Impact crusher and crusher long-term work in harsh conditions, which exacerbate the rotor bearing wear. Without rotor, crusher does not work, the rotor plays irreplaceable role on crusher. However, it is also fragile, switched bearing is not only expensive, but also very difficult to replace, often resulting in production lost. How to take effective measures to improve the life of impact crusher rotor bearing are our customers in the course of most concern. We need to pay more attention on its normal situation: 1. Make reasonable adjustment with the relationship between each other. Impact Crusher rotor bearing withstand the impact load, the size of the load suffered by the rolling body is not the same, the impact load under the joint effect is the maximum force, the inner and outer rings of the rolling body raceway also here in contact with the rolling body, getting the largest force. The inner ring does continual rotation, the point of contact on the track by the maximum force and then to force minimum continuous loop, so it is needed to make the inner ring tightly, so it will not produce a point to stay in the force. 2. Make the right choice of rotor bearing model. Double row spherical roller bearings have a strong bearing capacity, aligning performance advantages, so these bearings are more chose as rotor bearing. In addition, in the calculation of the selected bearing life, 5000 ~ 10000h should be appropriate. 3. Improve the accuracy of the rotor balance. Impact crusher has big rotor quality, high speed, rotor mass deviation caused by the rotor casting deviation and mounting plate hammer will generate unbalanced centrifugal force when the rotor rotates. The centrifugal force of the machine produce forced vibration, leading to the bearings and other mechanical damage to the crusher, so rotor balance test must be carried out. If the rotor diameter is small, we can change the blocking plate quality on both sides of the rotor body. If the diameter of the rotor body is big, the counterweight can be welded to the wall of the rotor in vitro. 4. Improve the crusher bearing force status; Adding rubber plate can increase the support softness, thereby absorbing a part of the vibration energy and improving the bearing stress condition, to achieve the purpose of prolonging lifetime. At the present, Fote Heavy Machinery has set up three state level machinery research institutes, and we also produce various kinds of impact crusher price,china impact crusher and free service for assembling various kinds of production line. 
The bag house filter used in crusher is generally smaller, ventilation is inadequate, so the dust cover and crusher cavity under crusher feed opening film is difficult to form slight negative pressure, causing large dust is filled in working environment, not conducive to breathing. Precipitator dust gets into the pipeline, the inlet tube at the elbow increases the system resistance, the bend parts is susceptible to be worn and clogged by dust. Using screw conveyor and dividing wheel conveying bag-type collector to trap dust increases power consumption and mechanical maintenance workload; often need to be demolish the lower sub-grid wheel feeder, with the passage of time, the feeder flange leaks air and exacerbate ash bucket air leakage. When the humidity is high, the dust particles get into precipitator is rougher than dry crushing materials, bag filter is easy to paste bag house, easy to plug the feeder, resulting in bag filter ventilation resistance substantially increases, ventilation capacity decreases and severe dust. The materials on the belt conveyor go into closed dust cover in falling process with the air and the material, dusty gas through the crevice and orifice hood walls spread to the outside of the cap, causes the pollution of the environment. In addition, due to the belt-corner dust point set incorrectly, the precipitator almost has no impact on lower level belt conveyor dust whatever open and stop it. The bag house and spare parts failure not only affect the normal dust removal, and increase equipment maintenance workload. Statistics from equipment maintenance and spare parts, poor quality is a more important reason to cause equipment failure. In order to reduce dust caused by the crusher casing air leakage, in the actual production, when the material is dry, we often water the crusher at the entrance, which result in bag dust collector filter bag paste bag and the feeder blockage are exacerbated. Because bag house is intermittent cleaning, when the precipitator is in normal working, the division round air leakage cannot to be neglected. Seen from the above, the crusher dust removal work is necessary. At the present, Fote Heavy Machinery has set up three state level machinery research institutes, and we also produce various kinds of crawler-type mobile crushers, stone crushing plant and free service for assembling various kinds of production line. vertical crusher: http://www.china-ftm.com/pros/compound_crusher.html
Based on years' experience and technology development, China Fote Machinery jaw crusher series are of 6 different models, which can meet most crushing requirements in primary and secondary crushing. Flexible discharge opening setting of jaw crusher allows perfect match with relative equipments. China Fote Machinery PE Series jaw crusher is easy to install, operate and maintain. As per Feedback, our experts will make continuous improvements on our products to meet customers' changing needs. Here, Fote will help you analyze the reasons and solutions: In normal work, it runs with the operation of the movable jaw, if tooth plate occurs abnormal jitter, the reason is usually very simple; in production, user can avoid if pay attention to it. What are the causes of tooth plate jitter? There are two possible reasons: ① jaw crusher crushing chamber internal liner looses or completely falls off, linings impact tooth plate, resulting in the tooth plate loses balance and appears abnormal jitter; ② tooth plate mounting bolts connecting with the movable jaw operation looses or fractures, causing tooth loosening bolts loose tooth plates and other components of the crushing cavity collide, exacerbating the frequency jitter. Tooth plate jitter is actually a problem very easy to deal with, take certain measures in production will be able to overcome it; first stop machine to check percussion, knock fixed wedge iron on the sidewall with a hammer and other tools to find the reason and tight liner ; Yet another approach is firmly connect to the bolt or replace it with a new bolt, to ensure the steady state of the tooth plate. Jaw crusher equipment is imported from abroad, improved combining with the development status of the domestic crushing industry; the jaw crusher tooth plate structure is located in the edge of the movable jaw, if tooth plate occurs abnormal jitter, it will not only exacerbate the degree of wear of the moving jaw and other parts, as well as may lead to the production does not work correctly; It is widely used in fields of mining, metallurgy, construction, smelting, hydropower and chemical industries etc. At the present, Fote Heavy Machinery has set up three state level machinery research institutes, and we also produce various kinds of jaw crusher supplier, jaw crusher supplier and free service for assembling various kinds of production line. pex jaw crusher: http://www.chinafote.com/pro/p1.html
Beneficiation is according to the differences in various minerals physical properties, physical properties and chemical properties to collect mineral raw materials. The implementation of this process, called mineral processing machinery. Beneficiation processing machinery is divided into crushing, grinding, screening, sorting (sorting) and dehydration machinery: (1) Crushing equipment: the common used includes jaw crusher, hammer crusher, cone crusher, roll crusher and impact crusher machine. (2) Mineral grinding machine: the most widely used includes drum mill, Rod mill, Ball mill, pebble mill and ultrafine laminated mill. (3) Screening machinery: Vibrating Screen and resonance screen. Grading machine and hydraulic and mechanical grading machines are widely used in the classification in the wet classification operating machinery. (4) Mechanical used in sorting are Shaking table, spiral chute, magnetic separator and Flotation machine. Flotation machine should have those basic requirements: In the flotation process, the flotation machine is the basic equipment to achieve mineral flotation separation. Flotation machines and ordinary machine flotation process should be reliable, wear-resistant, energy-saving, inexpensive and easy to manufacture, but also need to meet special needs. Flotation machine has the following basic requirements: 1.Inflatable role Flotation machine must inject sufficient amount of air and try to diffuse throughout the tank. More fine and more uniform, mineral particles has more opportunity contact with gas saturation; flotation efficiency is also higher. 2.Good stirring effect Flotation confidential should have a good stirring effect on the pulp, so that the mineral particles do not precipitate in suspension and can be evenly distributed in the tank, while promoting the dissolution of some of the poorly soluble pharmaceutical and facilitate agents and mineral particles fully interact. 3.Good circulation flow action It can increase the chance of contact of the ore particles and bubbles in the circulating flow of the slurry in the flotation machine. 4.Adjust the slurry liquid level and can work continuously In the flotation process, sometimes it needs to be adjusted to hold the thickness of the Mo layer and the slurry flow rate.   flotation-cell: http://www.fote-machine.com/product/flotation-machine.html
Vibrating feeder is commonly known as vibratory feeder, which can transfer the massive and granular materials from the storage silos uniformly, timely and continuously into the feeding devices. In the sand and stone production lines, it can feed continuously and uniformly for crushing machines, and it can also screen rough materials, which is widely used in metallurgy, mining, mineral processing, building materials and chemical industry, grinding industry, etc. Vibrating feeder has wide application ranges, which can adapt to the change of raw materials. It has characteristics such as simple structure, reliable production and strong production capacity, which is a kind of effective mixing equipment. But the material is always sticking in the barrel with insufficient mixing time and strong vibration. In order to reduce the vibration, some factories use floating raceway (i.e. not fixed with the cylinder, peristalsis is allowed), between the motor of the mixer and the reducer, the wheel group and the supporting roller, shock absorber is arranged between the support bracket and the floor. At the same time, use the rubber metal impairment compensation device with associated uranium reactor. When choosing a vibration feeder, the steel structure durability should be checked, especially observe the bearings, we should choose the appropriate shape to combine their own actual situation, so as to facilitate the installation. The screen amount for per hour should according to the vibration frequency and determine. In addition, vibrating feeder should save space with light weight and low driving power, because the screening surface can drive the vibration feeder, therefore we should ensure whether the rotation or pulsation amplitude is small, be clear of the vibration frequency of the vibration screen, its normal capacity is more than three thousand times per minute. The magnitude of the power is closely related with the yield.
