Manufacturer of dust collector for mine crusher

1. The dust collector shell of mine crusher has the flow pattern design of cyclone dust collector, which can play the role of local cyclone and reduce the load of filter bag. The shape of the cylinder vault is uniform in force. It also uses the high-pressure fan with its own equipment to blow back ash, which is not limited by the air source conditions in the use occasion, has fewer vulnerable parts, simple maintenance and reliable operation, and overcomes the shortcomings of pulse ash cleaning by compressed air. The backblow has a large action distance, and can use a long filter bag to make full use of the space and occupy a small area.

2. The trapezoidal flat bag used in the dust collector of mine crusher has a large amplitude and can shake off the accumulated dust with only one shock, which is conducive to improving the service life of the filter bag. In addition, the automatic control of rotary back-blowing is adopted to automatically adjust the cleaning cycle depending on the inlet concentration. Compared with the timing control mode, it is more reliable and reasonable.

The structure of dust collector of mine crusher:

It is composed of upper box, middle box, ash hopper, bracket, filter bag assembly, back-blown ash cleaning mechanism and unloading valve, etc. The dust collection and filtering system is mainly composed of filter bag, bag cage, flower board assembly, ash hopper and tangential air intake system, and the ash cleaning and unloading system is composed of high-pressure fan, rotary back-blower pipe and deceleration motor, and the electric control system is an automatic control system.

Fudong Environmental Protection explains for you several dust control measures of mine crusher factories and the selection of dust collectors

1. The dust collector of the crushing system of mine raw materials shall install airtight devices or dust collecting covers at the feeding and discharging ports of crushers or crushers for raw materials such as raw materials, lump ores, limestone, dolomite, bauxite and raw coal, as well as at the upper part of the vibrating screen and the operation point of the belt conveyor, and double-layer airtight covers shall be installed at the feeding point of the operation point.

The dust-producing equipment is covered with a closed cover or a dust-collecting chamber is made to form a uniform negative pressure inside the cover to avoid dust escaping, or an open suction hood is used to form a suction airflow. The exposed dust area is controlled in a narrow range, so that the dust-carrying airflow is sucked and pumped out. After being cleaned by a dust collector, the dust-carrying airflow is discharged into the atmosphere through an exhaust pipe (or chimney).

2. Dust removal measures should be taken for the unloading truck on the tank and the quantitative feeding station under the tank in the mixing batching tank. Dust generated by the unloading truck on the trough can be used as a movable vent ventilation trough or a vehicle-mounted dust collector, or with a large volume of airtight cover. Dust produced by quantitative discharge device under trough should be provided with double-layer airtight cover. For the dust raising of mixing batching tank, it is advisable to set up an independent dry dust collecting system and adopt a bag filter.

3. The dust removal system of crushing and conveying raw coal should adopt professional measures. The bag filter is selected for dust collector, which should have anti-static function, and the system and equipment should be grounded electrostatically and equipped with explosion relief device. The ash hopper should adopt heat preservation or tracing measures.

4. The air extraction and dust removal system of raw material yard includes ore crushing, screening and dust removal system, limestone crushing, screening and dust removal system, aluminium ore crushing and dust removal system, and coal crushing and dust removal system. For dust-producing points with centralized equipment, the same nature of dust and the same working system, large centralized dust-collecting system should be adopted as far as possible to facilitate treatment, such as limestone crushing and screening dust-collecting system, where as many as dozens of dust-producing points are concentrated in a large system. Otherwise, a small decentralized system can be used. Dry and effective bag filter is widely used in various dust removal systems.

The dust collector technology of Fudong crusher is an ingenious combination of cyclone dust removal mechanism and bag dust removal mechanism. It has the characteristics of purification efficiency up to 99%, higher filtration load, lighter wear of filter material, longer service life, stable and reliable operation.

Crusher dust collector is a control project designed for dust prevention and dust removal from material crushing. It can make the air dust concentration of post and exhaust meet the emission standards of environmental protection, including mining and mineral processing dust removal design. Bag filter of crusher belongs to high efficiency dust removal device, which has a wide range of applications, because it has the advantages of purification efficiency up to 99%, higher filtering load, lighter wear of filter material, longer service life, stable and reliable operation.

Crusher dust removal process is a clever combination of cyclone dust removal mechanism and bag dust removal mechanism. The shell adopts cyclone dust collector flow pattern design, which can play a local cyclone role, reduce the load of filter bags, the shape of cylinder vault, uniform force and good explosion resistance; it is not restricted by the air source conditions in the use occasion, has fewer vulnerable parts, convenient maintenance and reliable operation, overcomes the fraud of compressed air pulse ash cleaning, and the back-blowing effect. Long filter bags can be used for long distance, making full use of space and occupying small area. Ladder flat bags are arranged in the cylinder body, which has simple structure and compact structure and improves the service life of the filter bags.

The dust removal equipment of crusher is to use centrifugal fan to generate negative pressure area at dust sealing cover, and to inhale dust into the dust removal equipment. A dust removal bag is arranged in the pulse bag filter. When the dust-containing gas passes through the filter bag, the dust is blocked and separated, and the purified gas is discharged by the fan. The dust on the surface of the filter bag is injected by electromagnetic pulse valve to make it fall off the filter bag. The compressed air injection is controlled automatically by PLC without human control, which is a major feature of the filter bag.

The features of dust collector of mine crusher are as follows:

1. Bag dust collector is not only widely used for crushing, but also for dust control in various industries. It can achieve good dust removal effect and fully meet the design requirements.

2. It can be used to deal with the dust produced by the processes of perforation, drilling, blasting, loading and crushing in fragmented open-pit mining or underground mining.

3. It is simple in structure, compact in size, easy to migrate, moistureproof and durable.

4. Low operating cost and perfect design process are conducive to the efficient and stable operation of bag filter, reduce energy consumption and effectively reduce the loss of filter bag and maintenance work.
