Vibrator of Guangzhou Huabao mining machinery vibrating screen

In the working process of the vibrating screen, it is often affected by the bearing to make the screen machine vibrate strongly, which is mainly affected by the following five factors:

1. eccentric vibration of the exciter

   if it is the cause of the exciter, increase the weight of the eccentric block and adjust the amplitude; If it is a vibrating motor, the amplitude adjustment depends on the angle between the eccentric blocks at both ends of the shaft to change the size of the exciting force. If the angle is small, the exciting force will increase and the amplitude will increase; On the contrary, the larger the angle, the smaller the exciting force and the smaller the amplitude

   Through the bearing test of environmental cleaning screen, the results show that too small or too large radial clearance will cause greater vibration of the bearing system. When the radial clearance is too small, it will cause high frequency vibration; When the radial clearance is too large, it will cause low frequency vibration

2. geometric accuracy of the bearing

   excessive exciting force of the vibrating screen will cause the bearing to bear a very large radial force, resulting in strong vibration. The higher the bearing accuracy is, the smaller the vibration is. Therefore, to rece bearing vibration, the surface machining accuracy of rolling element should be improved first

   The bearing friction and lubrication is the main source of vibration which is difficult to control for the vibrating screen. Because the vibrating screen is maintained by a large exciting force, the bearing will suffer a large radial force. During the working process of the vibrating screen, the huge exciting force will cause the elastic vibration of the bearing system

3. the fit of outer ring and supporting hole

   the fit of outer ring and supporting hole will affect the transmission of vibration. If the fit is tight, it will force the raceway to deform, increase the shape error, and increase the vibration. Usually, the material is in the shaker. The speed of operation and propagation. After the material enters the material inlet from the vibrating screen, it will fall onto the screen and then spread to the surrounding area. Diffusion will graally complete the screening process. The smaller the angle of the vibrating motor is, the faster the material diffuses to the surrounding area

Description of vibrating screen st collector: vibrating screen st collector is composed of st collector, fan, PLC automatic pulse injection system, hanger, access door, sealing soft curtain, etc. In the proction time, we use our latest design, more optimized in the structural configuration, at the same time, the use of the ash collection performance is more excellent, the use of vibrating screen st collector can avoid the st flying around, causing pollution to the environment, but also to protect the health of Rui staff, our professional after-sales service team is dedicated to serve you
vibrating screen st collector, also known as gravel screening st collector, is a kind of st purification equipment mainly used for vibrating screen operation, which can effectively deal with the pollution problem caused by vibrating screen in the process of vibration. At present, the vibrating screen st collector has been widely used in mining, building materials, grain, chemical instry, casting, ceramics and other instries. It is a more advanced bag st collector or material collection equipment
operation characteristics of vibrating screen st collector
2. Low power consumption and low operation and management costs
3. The pulse injection cleaning of st collector is controlled by PLC automatically, which is stable and reliable
4. It is most suitable for st removal of vibrating screen system for coal, sinter, ore and other raw materials
5. The one-time investment is small. Compared with other precipitators, it can run for 2 months and recover the investment cost
6. According to the nature and temperature of the material, different filter materials are selected to ensure the st removal effect and service life
7. The st recovered by the vibrating screen st collector directly returns to the bin or belt, without secondary pollution, saving manpower and material resources and effectively recycling raw materials
8. High purification efficiency, in line with the requirements of national environmental protection index, completely solve the problem of st pollution of vibrating screen
working process of vibrating screen st collector
according to different working conditions and different requirements for st removal equipment, we have provided more than ten specifications of ZC type and PPC type vibrating screen st collectors for users. For specific technical parameters, please refer to the table below. You can choose according to the actual situation of st in vibrating screen operation
the vibrating screen of the vibrating screen st collector proces a lot of st in the working process. When the MC series st collector starts to work, the centrifugal fan of the st collector is used to form a negative pressure area at the st overflow, and the st containing gas is sucked into the st collector. There are several filter bags in the vibrating screen st collector. When the st containing gas passes through the filter bag, the st is blocked and separated, and the purified gas is discharged through the fan
the vibrating screen st collector is a kind of st removal device of MC type pulse bag filter, which is specially used to proce st when the vibrating screen is working. Due to the difference of font, it is also called vibrating screen st collector. The device is composed of st collector, fan, PLC automatic pulse injection system, hanger, access door, sealing soft curtain, etc. The use of vibrating screen st remover can avoid the st flying around, causing pollution to the environment, and has made a certain contribution to the protection of the earth's environment. When the st on the surface of the filter bag increases and the knife resistance value reaches the predetermined value, the pressure sensor sends an indication signal to the electric control box, and the pulse injection system automatically controls the PLC to blow the filter bag, shake off the st attached to the filter bag, and directly reach the belt through the sealed ash discharge pipe. That is to say, the good filtration performance of the filter bag is always maintained without secondary st< 1. Pulse off-line cleaning, the efficiency is more than 99.9%, and the st does not proce secondary adsorption
2. The pressure of air source is only 0.2 MPa and 0.3 MPa, and the service life of filter bag and pulse valve is long
3. To deal with high temperature and humidity gas, the filtering wind speed can reach 1.2m/min
4. The filter bag is easy to disassemble and has good sealing performance< It is easy to operate and reliable
6. The new type of FMS microporous thin composite filter material can adapt to various flue gas conditions and has a service life of more than 3 years
7. Small area, low investment and good effect
