This motion causes the heavier dust particles to move towards the walls of the chamber, where they are collected and removed. Cyclone dust collectors are effective at handling large volumes of dust and are commonly used in heavy-duty belt grinding applications.
Baghouse dust collectors
Baghouse dust collectors, also known as fabric collectors, are similar to mechanical dust collectors in terms of their filtration mechanism. However, they feature a series of cloth filter bags instead of filters or bags. The dust-laden air passes through the bags, and the dust particles are captured on the outer surface of the bags. Baghouse dust collectors are known for their high filtration efficiency and are often used in belt grinding operations where fine dust particles need to be controlled.
Mechanical Dust Collectors
Principle of operation
Mechanical dust collectors operate using a filtration system consisting of filter bags or cartridges. The contaminated air enters the dust collector through an inlet, and the larger particles are immediately separated using a baffle or a pre-filter stage. The remaining fine dust particles are then collected on the surface of the filter bags or cartridges. The cleaned air exits the dust collector through an outlet and can be discharged back into the workplace or released outdoors.
Advantages
