As we all know, ultra-fine grinding machine is a very common grinding machine, which has a very wide range of applications in the market. The ultrafine mill can be used in a single machine or widely used in the grinding production line. Ultra-fine grinding machine Equipment grinding plants are vital, so what should we do to maintain the efficient production and safe operation of ultra-fine mills? Improving safety in a way that protects workers' safety is an important way to find the wrong way to operate and properly operate the ultra-fine mill. The following aspects are scientific means to improve the performance of the ultra-fine mill and to ensure the grinding capacity of the grinding mill.
1. Rely on the operation and maintenance manual of the ultra-fine mill to ensure the smooth operation of the ultra-fine mill.
2. Install the ultra-fine mill and master the flow chart of the ultrafine mill.
3. Adopt innovative ultra-fine grinding machine and introduce new grinding technology to ensure work quality and life safety.
In the process of improving the production efficiency of the ultra-fine mill in the grinding mill, firstly, the Raymond mill equipment is started under non-load conditions. If there is some material in the device when the Raymond mill is started, the pressure of the motor will be A large increase, a more serious degree will burn the motor. Therefore, when we start the ultra-fine mill, please make sure that your equipment is empty, then add gypsum or limestone into the ultra-fine mill after running; secondly, input the appropriate raw materials of the ultra-fine mill, generally speaking Too little feed can not reach the rated grinding capacity, and excessive push will be blocked at the feed port, sometimes it may damage the impeller of the mill; third, we should pay more attention to lubricating the ultra-fine grinding at fixed time intervals. The maintenance and lubrication system of the ultra-fine mill is very important.

Hammer head is a very important core component for hammer sanding machine, hammer <a href="http://www.demihidraulik.com/products/sand-making-machine.html">sand making machine</a> and counter-type sand making machine equipment. It is also one of the main wearing parts of the equipment. It is the key equipment for breaking. The suitability of the weight of the hammer is related to the energy consumption of the entire sand making machine and the working efficiency of the equipment. Below we SBM will provide you with detailed analysis and calculation of the hammer weight calculation of the hammer sand making machine.
Since the hammer head of the hammer <a href="http://www.punkdogwine.com/crusher-equipment/zenith-vsi-sand-making-machine.html">sand making machine</a> (sanding machine) is grounded on the rotor, the correct selection of the weight of the hammer head has a great effect on the crushing effect and energy consumption. If the weight of the hammer is too small, it may not meet the requirement of crushing the nugget once it is hammered; if it is too large, the useless power consumption is too large, which is uneconomical. Therefore, the weight of the hammer must meet the hammering once to break the ore, and the well minimizes the useless power consumption. At the same time, the hammer must not be overturned backwards.
There are two ways to calculate the weight of the hammer: one is to calculate the weight of the hammer according to the kinetic energy generated by moving the hammer to equal the crushing work required for the broken ore; the other is based on the principle that the collision theory works most equally. Calculate the weight of the hammer and. The former method does not consider the speed loss after the hammer hits the ore block, so the calculated weight of the hammer head tends to be too small. It needs to be corrected according to the actual situation.

The sand washing machine filters the sand by the sorting function of the screen. The sand washing machine requires strong toughness and wear resistance for the material of the screen. After repeated verification by our technicians, it is determined that the sand washing effect will be better when there is expansion force of the sand washing machine screen. Below, we will repeat the process of the sand washing machine test. First, a sand washing machine with quality inspection was selected from the sand washing machine manufacturing workshop and transported to a sand washing machine near the factory for testing. The sand washing machine can be turned on after determining that the power connection is normal, the electric control cabinet, the bearing, and the runner are inspected. Secondly, the sand is fed into the rotating bucket through the belt conveyor, and then the water is pumped to the water. Under the impact of the water, the dust contained in the sand is cleaned, and the gravel and wood chips are separated by the screen. The size of the screen is essentially the size of the mesh, and the diameter of the wire of the woven mesh directly affects the size of the mesh. In order to ensure the uniformity of the size of the screen, China has established a standard for the screen, which specifies the diameter of the thread and the size of the screen and its error. For the sander screen, we change a variety of materials. For example, nylon, manganese steel, high-chromium alloy, rubber, stainless steel, etc., screens of different materials are installed on the sand washing machine for sand washing work. After 10 days of continuous operation of the sand washing machine, it is found that the mesh holes of different materials have different degrees of wear. The chrome-manganese screen with tension is less worn. Therefore, it is best to wash the sand when the screen of the sand washing machine has a certain tension.
The slag vertical mill is widely used. The SBM Industrial Technology Group below introduces the precautions in the use of the slag energy savingvertical roller mill. 1. During the use of the slag vertical mill, there should be fixed personnel responsible for the inspection, and the operators must have a certain level of technology. The slag vertical mill must perform the necessary technical training for the operator before installation to understand the principle performance of the slag vertical mill and familiar with the operating procedures. 2. After using the slag vertical mill for a period of time, it should be repaired. At the same time, the wearing parts such as the grinding roller and the blade should be repaired and replaced. The grinding roller device should be carefully checked before and after the use. There is looseness and the grease is added. 3, in order to make the slag vertical mill normal, the equipment "equipment maintenance and safety operation system" should be established to ensure the long-term safe operation of the slag vertical roller mill operation, and necessary maintenance tools and grease and corresponding accessories. 4. When the grinding roller device of the slag vertical mill is used for more than 500 hours to replace the grinding roller, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time. The fueling tool can be used with manual fuel pump and grease gun. .
As the main equipment used in the grinding of the ore milling production line, the vertical roller mill can easily achieve the purpose of changing the material discharge granularity and material shape. The model is complete and widely used. Among them, among the main components, grinding Roller as a wearing part, its material quality and processing technology will affect the grinding effect of the vertical mill, so it is very important for its choice, then where to buy the vertical mill roller? It is recommended to go to Shibang Industrial Technology Group to make purchases. 1, the grinding roller material is excellent The choice of the material for the vertical mill is very particular, because the length of use of the roller is related to the overall economic benefits. The grinding roller equipped with Shibang Industrial Technology Group adopts the alloying method. On the basis of ultra-high manganese material, it uses advanced rare earth metamorphism treatment, precious elements such as vanadium and vanadium to strengthen the matrix, so that it has toughness and wear resistance. It has also been upgraded a lot. The excellent quality of the grinding roller makes the reliability enhanced, and the comprehensive performance has been improved. It is one of the reasons for purchasing. 2, strong technology For the processing of the grinding roller, it can also reflect the quality of its quality. The grinding roller of the vertical roller mill produced by Shibang Industrial Technology Group first adopts the double refining technology outside the furnace, which effectively reduces the harmful elements and improves the toughness and wear resistance of the material steel. Secondly, the heat treatment process is optimized to make the grinding The hardness of the roller is more uniform, and the impact abrasion resistance is stronger, and it is more durable in the process of grinding the material. This is the reason why users are advised to come to this choice. 3. Other reasons In addition, one of the reasons for the manufacturer to purchase the vertical mill grinding roller is that it is very proficient in the number of grinding rollers installed, the fastening method, etc. After all, as a mining equipment expert, not only the production of accessories, Also know the key to the accessories.
Ultra-fine vertical grinding has the effect of over-grinding. It can be used for grading, drying and dispersing of complete equipment. It can be combined with vertical mill to form pre-grinding, mixing grinding, semi-grinding, etc. Grinding and other new process complete process, due to the principle of ultrafine mill, the new grinding system process can reduce the grinding power consumption system by about 50%, the output can be improved a lot, can be applied to cement or raw materials and cooked In the material, the new grinding system is suitable for the grinding of a variety of mineral powders, thus solving the current situation of insufficient grinding capacity with the new standard. The grinding system has been widely used in many industries. There are many models of ultra-fine vertical grinding. The fine ore fineness and high screening rate after ultra-fine vertical grinding process convey a large amount of production for refractory materials, cement, glass flux, building materials, paint, ceramics, chemical industry and other industrial parts. Good raw materials have improved the economic price of dolomite. The fineness of the ultrafine mill can be adjusted during the grinding process. When processing different ores and crystal materials, in order to improve the production time of the grinding material, the production can be reduced by reducing the consumption, and the particle size is selected to be smaller than The powder below 1mm is directly into the grinding machine, and the remaining more than 1mm is re-extruded into the main machine, which greatly reduces the particle size of the slag, which shortens the grinding time and increases the output of the mill. The grinding process and equipment also need to be adjusted accordingly.
In the ore milling production line, an inadvertent misuse, an unintentional neglect, will cause the production error to widen. The fineness of the heavy calcium ultrafine mill is arbitrarily adjusted between 300 mesh and 2500 mesh. According to the user's reflection, Shibang Industrial Technology Group analyzes why the fineness of its production is not up to standard. The main reason is ? First of all, let's take a look at the composition of the heavy calcium superfine mill. The complete set of equipment includes hammer crusher, bucket elevator, storage bin, vibrating feeder, superfine mill host, frequency classifier, double The cyclone dust collector, pulse dust removal system, high pressure fan, air compressor, and electrical control system are realized by the combination of the entire line. First, the speed of the fan of the heavy calcium ultrafine mill affects the fineness of the discharge. In the process of milling, if the speed of the fan is too high and the wind is too large, the material that does not meet the fineness requirement will be blown into the powder collector. Conversely, if the material has a large specific gravity, the wind will be too small. Affects the discharge, which in turn affects the overall fineness. This requires us to adjust the motor and current to achieve the adjustment of the fan speed. Second, in the analysis machine of the heavy calcium ultra-fine mill, a large number of blades are installed. These blades will wear after a period of use, which directly affects the efficiency of the analyzer. Operators should pay attention to the maintenance during maintenance. Once the blade wear phenomenon occurs, it should be replaced in time to avoid affecting the quality of the milling. Third, under normal circumstances, the production of medium-heavy calcium ultra-fine grinding machine grinding roller and grinding ring is not in direct contact. However, as the use time of the equipment increases, the degree of friction between the grinding roller, the grinding ring and the material increases, and the wear degree of the grinding ring increases. The material is not fully ground and the fineness of the finished product is affected. The operator should record the service life and replacement cycle of the grinding roller ring and replace the new fittings regularly. In short, there are many factors affecting the fineness of the super-calcium superfine mill. In normal applications, only correct operation is carried out, and the equipment is carefully maintained and maintained to better ensure the quality of the mill. Once the fineness of the heavy calcium ultrafine mill is not up to the requirements, it is necessary to check the cause in time, and prescribe the right medicine to ensure the quality of the powder.
Jaw crushers are machines that are often used in the field of ore crushing. However, many people will continue to malfunction during use and have to stop working to repair the machine. Tip: In fact, as long as it avoids the following non-standard phenomena in the operation, you can avoid damage to the machine. 1. Maintenance of the machine from time to time. In the use of the stone crushing equipment, the screws of the internal parts of the machine or the screws of the fixed machine are often loosened due to the great force of the machine. This requires regular reinforcement of the machine's screws. Second, do not promptly replace the lubricant with the machine. After the machine has been in use for a period of time, the internal lubricant will reduce the lubrication effect, and the debris that falls off during the running of the machine will also increase the wear of the machine. Therefore, when the lubricant has been used for a while, it must be replaced in time. And after the replacement, use kerosene to thoroughly clean the interior, leaving no crumbs left. This way the machine is not easy to wear. Third, the internal temperature of the machine is too high. Jaw crusher generates a lot of heat due to friction during use. If this heat is not released in time, it will damage the machine. For example, the center axis of the machine will be deformed due to high temperature and will be damaged when the stone is broken. Therefore, always pay attention to the internal temperature when using the crusher. If the machine temperature is too high, stop the work in time, and then use it when the temperature is reduced. 4. The iron pieces were not picked out when the raw materials were added. If the iron is in the raw material, the jaws of the jaw crusher will be destroyed and the machine will not be able to be used. 5. Add raw materials unevenly. This will damage the machine due to excessive load when too much material enters the machine.
VSI sand making machine is the most advanced and most advanced mechanism sand equipment. It is widely used in hard pebbles, river pebbles, granite, basalt, diabase, andesite, dolomite, iron ore, ore tailings, and stone chips. Sand making is a high-quality gravel aggregate for highways, high-speed railways, high-rise buildings, municipal, hydropower dam construction, concrete mixing stations, and is the preferred equipment for artificial sand and stone shaping. There are some repairs during the use of the VSI sand making machine: 1. The direction of rotation of the rotor must be counterclockwise when viewed from above the device. If the direction of rotation is incorrect, it will cause serious damage to the rotor. The two motors must be in the same direction of rotation. When the judgment is unclear, the V-belt can be removed to observe the steering of the two motors. 2, VSI sand making machine lubrication method is thin oil lubrication, generally do not need to change the oil frequently. The equipment is equipped with the German original thin oil lubrication station. The double oil pump complements the oil supply, and automatically stops when there is no oil flow or oil pressure. The oil cooling and heating device ensures that the bearing lubrication is always in the best condition. 3. Excessive particle size (greater than 60mm) mixed with iron or feedstock in the iron feedstock has a significant impact on the life of the throwing head. Therefore, always remove the iron on the iron remover and check if the screen is damaged. The use record of the throwing head indicates that the damage caused by abnormal causes can be eliminated, and the use time can reach more than 2700 h. For this purpose, a separator is mounted on the feed tape. 4, the tension of the drive tape The appropriate tension is extremely important for the long-term, normal operating state of the drive tape, especially for dual-motor drive equipment. If the current of one motor is lower than the current of the other motor, it may be caused by the difference in the tape tension of the two motors. After the new tape is idle for 30 minutes, the tension should be re-adjusted, and then the feeding operation is run for 8 hours. Adjust again to eliminate the natural extension of the tape, otherwise it will easily burn the tape. 5, dust control usually in the normal operation process, the air turbulence in the crushing chamber creates an ideal dust collecting environment, and does not need to use dust collecting equipment to reduce dust, but start or stop or insufficient feeding during operation A large amount of dust is discharged, and a water spray device can be installed at the discharge port, and a lock associated with the motor can be turned on/off, so that the sand machine automatically starts the spray device to control the dust discharge when driving or stopping.
SBM Industrial Technology Group introduces you to the four skills of cement vertical roller mill maintenance. First of all, production maintenance mainly refers to the elimination of production planning problems, the production can not keep up, the finished products are not up to standard, etc. There are two possible failure factors: one is the performance of the equipment itself, the other is the level of the operator, the general test machine does not There are quality problems, and the factors affecting the quality of the later-grown grinding equipment are much smaller, which may not be caused by the operator. For example, it is impossible to control the uniform feeding, the startup shutdown sequence is incorrect, and the valves are open in error, for example, the locker is not sealed. Jiahui will produce less or no powder, and the yield will be low. The uneven feeding will affect the uniformity of the finished product and the problem of blockage has occurred. Second, predictive maintenance is similar to preventive maintenance, but it is fundamentally different. Prevention is all possible problems, but the substance does not necessarily occur, and the prediction is about to happen. It has been predicted to some extent, but it has not yet Cause serious consequences. Predictively, according to the information provided by the state monitoring and diagnostic technology, necessary and appropriate maintenance can be carried out before the failure occurs. Most skilled operators can find potential faults in advance through the sound and finished product status, so as to prevent and control early. Third, preventive maintenance, develop detailed plans for the operation of milling equipment, including production volume, schedule, professional maintenance department, etc. Reasonable work arrangements and preventive measures can extend the service life of equipment and accessories and improve production efficiency. The following points: 1. Develop a reasonable production plan to avoid overworked equipment. 2. Set up a special maintenance department to check regularly and find out that the abnormal quality of finished products and production efficiency are eliminated in time. 3. Lubricate or replace the minor or severe wear parts of the vertical mill. Fourth, fault repair refers to the unplanned maintenance taken when the cement vertical mill fails or the performance is degraded. It is a behavior that solves the fault more specifically. For example, the powder collector does not produce powder, the bearing locks, and advances. Problems such as abnormal dust at the material port, such common faults SBM Industrial Technology Group mine has introduced the detailed technical description of the grinding equipment. In addition, the fault problem cannot be handled at will. Look for the technician or check and eliminate it under the knowledge of the technician. The whole process should be carried out under power-off conditions to avoid other accidents.
