Mine crusher dust collector

The dust collector of the mine crusher is mainly composed of upper and lower boxes, ash hopper, ash discharge device, filtration device, spraying device, induced draft fan and other main components. It has the advantages of large dust treatment, good purification effect, stable operation, saving installation space, and easy daily maintenance. It is used in conjunction with hammer crushers, jaw crushers, and impact crushers.

The dust removal mechanism of the mine crusher dust collector is very simple. Like the dust removal mechanism of a mask, it is achieved by mechanically intercepting fly ash particles in the flue gas through filter materials. But in addition, the first received fly ash particles also form a stable and dense layer of ash on the surface of the filter material (generally referred to as a filter cake or filter bed), which plays a good filtering role, especially in dust removal equipment that uses woven cloth as filter bags. This layer of filter bed plays the main filtering role.

Characteristics of mine crusher dust collector: The shell cyclone dust collector has a flow pattern design that can play a local cyclone role and reduce the load on the filter bag The shape of the cylindrical dome is uniform in force and has strong blast resistance. The dust collector of the mine crusher is not limited by the gas source conditions of the usage site, with few vulnerable parts, easy maintenance, and operation Overcoming the cheating problem of compressed air pulse dust cleaning The anti blowing effect distance is large, and long filter bags can be used to fully utilize space and occupy a small area.

Working principle of dust collector for mine crusher:

The dust containing gas enters the upper space of the filter chamber in a tangential direction. Under the centrifugal force of large particles and condensed dust particles, they spin down the ash hopper along the cylinder wall. Small particles disperse in the gaps between the filter bags in the filter chamber and are blocked. Purified air passes through the bag wall and is collected in the clean room through the filter bag inlet on the flower plate. It is then sucked in by the ventilation fan and discharged into the atmosphere As the filtration process progresses, dust adheres to the surface of the bag, and the resistance of the filter bag gradually increases. When the upper limit of the anti blowing control resistance is reached, the differential pressure transmitter connected to the front and rear interfaces of the dust collector sends a signal to automatically start the anti blowing mechanism.

Dust prevention of mine crusher dust collector:

1、 Rock drilling for dust prevention. Wet rock drilling with good dust removal efficiency is preferred for mining dust collectors. When wet rock drilling conditions are not available, dry dust collection rock drilling can be used. Dry dust collection rock drilling is divided into two forms: using a dust hood to extract dust at the rock drilling mouth or extracting dust at the bottom of the hole. When it is not suitable to use a large amount of water, foam can be used for dust removal, that is, foam can be pressed into the hole bottom or sprayed at the hole mouth, or dust laden air can be introduced into foam dust remover for purification.

2、 Blasting dust prevention. The amount of dust produced during ore blasting is large, and the dust production time is concentrated. The main dust prevention measures are spray watering and water seal blasting. The blasting wave is often used to start the spray, the purified water curtain and the water wind ejector.

3、 Dust prevention during shipment. Ore stacking, rock loader, loader, scraper, tramcar, belt conveyor and ore drawing and loading of pass all produce a large amount of dust. Measures such as spray watering and closed ventilation can be taken to prevent dust emission.

4、 Shattered and dustproof. For the dust generated during the operation of various crushing equipment, wet dust prevention and mechanical dust removal combined dust removal measures can be adopted on the basis of equipment sealing. The purification equipment for mechanical dust removal adopts bag filter or wet dust collector. Wet dust collectors should be used for dust removal in underground crushing chambers. When the exhaust of the dust removal system cannot be discharged to the return airway or ground, but can only be discharged on site, the exhaust needs to be treated by a filter.
