The LT filter cartridge sandblasting dust collector adopts a pulse blowing dust cleaning method, which has the advantages of good dust cleaning effect, high purification efficiency, large processing air volume, long filter cartridge life, low maintenance workload, and safe and reliable operation. LTM filter cartridge sandblasting dust collector is widely used for dust removal and purification of non fibrous industrial dust and material recovery in various industrial and mining enterprises such as metallurgy, building materials, machinery, chemical industry, and mining.

The working principle of LT filter cartridge dust collector is as follows: the dusty gas enters the filter chamber through the ash hopper (or lower open flange), and the coarser particles directly fall into the ash hopper or ash bin. The dusty gas is filtered by the filter cartridge, and the dust is trapped on the surface of the filter cartridge. The clean gas passes through the bag mouth to the clean air chamber and is discharged into the atmosphere by the induced draft fan. When the dust on the surface of the filter cartridge continues to increase, causing the equipment resistance to rise to the set value, the time relay (or micro differential pressure controller) outputs a signal, and the programmable controller starts to work. The pulse valves are opened one by one, allowing compressed air to blow and clean the filter bag through the nozzle, causing the filter bag to suddenly expand. Under the action of reverse airflow, the dust attached to the bag surface quickly separates from the filter bag and falls into the ash hopper (or ash bin), and the dust is discharged through the flap valve. Spray blowing only cleans the filter bags one by one, while other filter bags continue to filter normally without stopping the fan.
