At present, vibrating screen dust remover has been widely used in mining, building materials, grain, chemical industry, casting, ceramics and other industries, and is a relatively bag dust collector or material collection equipment.



Working principle of mine vibrating screen dust collector:
A large amount of dust is generated during the work of vibrating screen. When the vibrating screen dust remover starts to work, the centrifugal fan of the dust remover forms a negative pressure area at the dust overflow place, and the dust containing gas is inhaled into the dust collector. There are several filter bags in the dust collector. When the dust containing gas passes through the filter bag, the dust is blocked and separated, and the purified gas is discharged through the fan. When the dust on the surface of the filter bag increases and the cutter resistance value reaches the predetermined value, the pressure sensor sends the indicator signal to the electric control box. The pulse blowing system controlled by PLC automatically sprays the filter bag automatically, and the dust attached to the filter bag is shaken off, and the sealed ash discharge pipe directly reaches the belt. That is, the filter bag is always kept good filtration performance, and no secondary dust is generated. According to the work of vibrating screen and the actual situation on site, the design and installation of dust removal device are carried out, and the problems such as overhaul and screen changing of vibrating screen are fully considered.

It is used together with hammer crusher, jaw crusher and impact crusher.

The dust collector of mine crushing system is used in the crushing system of the mine to solve the problem of excessive dust and serious pollution in the process of crushing, separation and transportation of ore by machine. The dust collector of the crusher is installed with dust collection device at the dust point, and the dust is sucked into the dust collector box of the crusher through negative pressure for purification treatment, so as to separate the dust from the clean air.

The dust collector of mine crushing system uses centrifugal fan to produce negative pressure area at the dust sealing cover, and inhales the dust into the dust removal equipment. The pulse bag filter is equipped with dust removal cloth bag. When the dust gas passes through the filter bag, the dust is blocked and separated, and the purified gas is discharged through the fan. The dust on the surface of the filter bag is injected by the electromagnetic pulse valve to make it fall off the filter bag. The compressed air injection is automatically controlled by PLC without human control, which is one of its major characteristics. Pulse bag filter is not only used in crushing, but also used in dust control of various industries. It has achieved good dust removal effect and reached the design requirements. It is an ideal dust removal equipment at present.

5.Mine dust collector

The mine dust collector is used to deal with the crushing of the mine. The working environment and atmospheric environment are seriously polluted due to the dust emission in the process of piercing, drilling, blasting, shipping, crushing and so on. In dry rock drilling without dust control measures, the dust concentration of working face can reach hundreds or thousands of milligrams per meter. When there is no dust prevention measures in underground crushing chamber, the dust concentration can reach several thousand milligrams per meter. The mine dust collector should be suitable for the characteristics of the mine. It is required to be simple in structure, small and compact in size, easy to move, moisture-proof and durable. When the comprehensive dust control measures adopted in each working procedure still fail to meet the requirements, it is necessary to take personal protection.

It can collect various kinds of pollution dust with fine particle size, cohesiveness, fiber, chemistry, electrification and high temperature. The dust collector can clean and discharge dust automatically.

Dust prevention of mine crushing: on the basis of airtight equipment, the combined measures of wet dust prevention and mechanical dust removal can be adopted for the dust generated by various crushing equipment. The purification equipment of mechanical dust removal adopts bag type dust collector or wet type dust collector. Wet dust collector should be selected for dust removal of underground crushing chamber. When the exhaust air of dust removal system can not be discharged to return air roadway or ground, but can only be discharged locally, the exhaust air shall be treated by filter.

Mine perforation dust prevention: a large amount of dust is produced during the operation of the open-pit drilling rig. Measures such as air-water mixed wet rock drilling inside the hole, dry dust catching outside the hole and wet dust catching can be adopted. Because of the high initial dust concentration, two-stage purification of cyclone and bag filter is needed.
