The working principle of the dust collector matched with shot blasting machines mainly consists of four stages: dust capture, filtration, dust particle separation and exhaust discharge.
First of all, while the shot blasting machine is running, dust and impurities are drawn into the dust collector by airflow. Exhaust gas flows in through the air inlet of the dust collector and makes contact with filter bags. Large dust particles and contaminants are trapped on the surface of the filter bags.
Subsequently, the trapped dust and contaminants build up to form a primary dust layer, which effectively blocks fine dust from penetrating the filter media. As operation continues, further dust accumulates on the primary layer and forms a dense filter cake. This filter layer can intercept micro particles larger than 0.01 microns, realizing highly efficient dust removal.
After filtration, clean air passes through airflow channels into the particle settling chamber. Inside this chamber, airflow velocity drops sharply. Under gravity, residual dust particles settle down and fall into the dust hopper. This process ensures that only extremely fine particles are carried out with the airflow.
In the final stage, the purified air is released through the exhaust outlet. The exhausted gas contains merely trace amounts of dust and fully complies with environmental emission standards, delivering clean and eco-friendly exhaust air.
