Dust collector appears with the development of science and technology and social production, as the filter emissions in the production of industrial equipment, with the environmental problem more and more prominent, countries are increasingly strict with emissions management, and also have higher requirement of filter, dust removal equipment in today's industrial production process has been widely used.

Of all the dust removal equipment, bag filter is widely used in industrial production of dust removal equipment. This is because the bag filter through years of development, in the continuous improvement, dust removal effect is better, the effect is more and more stable, and service life is getting longer and longer, and is relatively reasonable cost.

In building materials production, lime rotary kiln, ceramic sand rotary kiln, rotary kiln, the gas is generated by fuel combustion, and is part source of air pollution, in order to actively cooperate with the needs of the national policy of energy saving and emission reduction, and to protect the atmosphere, reducing pollution many building materials production enterprises also start to use dust removal equipment in the production line of rotary kiln.

The dust removal efficiency of bag filter can reach more than 99.99%, and emission concentration is lower than 50 mg/m³, even less than 10 mg/m³, achieving smoke-free emission, and being close to zero pollution. The main clean production workshop of many cement plants, starts from installing bag filter in the grinding workshop.
