Product Introduction  

Mining bag dust collectors are dust removal equipment used for collecting dust from crushing operations, including dust collectors for crushers, vibration screen dust collectors, belt conveyor dust collectors, etc. The characteristics of dust produced during the operation of mining machinery are large dust volumes, so when selecting a mining bag dust collector, the air volume of the dust collector should be appropriately chosen. In fact, based on our experience, slightly selecting a larger air volume yields better dust collection results. Due to the large dust volumes during crushing and screening, a smaller design can lead to dust overflow.

The mining bag dust collector is composed of a filtering chamber, filter bags, clean air chamber, ash hopper, ash discharge valve, pulse-jet device, electric control box, and more. The mining bag dust collector is a new energy-saving dust collector with a large air handling capacity developed by our company based on the MD-type single machine pulse-jet bag dust collector and PPC gas box pulse dust collector, combining practical experience. It overcomes the shortcomings of small air handling capacity of single machine dust collectors and insufficient cleaning strength in the gas box partition, as well as uneven air distribution in and out. The structure of the mining bag dust collector has its unique features, thereby improving the dust collection efficiency, adaptability, and extending the service life of the filter bags. After many years of production practice, the equipment operates stably, requires minimal maintenance, and has a wide range of combinations, earning high praise from a large number of mining enterprise users.

Operation Principle
Mine crushers and vibrating screens allow dusty gas to enter the dust collector through the ash hopper inlet. The gas flows through the lower ash hopper into the filtering chamber, where coarser particles fall directly into the ash hopper. The filtered clean air enters the clean air chamber and is exhausted into the atmosphere by a fan. As the filtering time increases, more dust accumulates on the filter bags, increasing resistance and gradually reducing the treated air volume, affecting the normal operation of the equipment. This series employs a continuous timed cycle for dust cleaning. During cleaning, a pulse controller signals the sequential opening of each pulse valve. The compressed air in the gas separator is instantly directed through the pulse valve to the jet pipe and into the filter bags, causing them to rapidly expand and remove the dust layer on the surface, restoring the filter resistance. The cleaned dust falls into the ash hopper and is discharged through a dust discharge valve. After all filter bags have been jet cleaned, the dust collector resumes normal operation.
