The dust bag can be used in the flue gas treatment and dust removal systems of iron making plants, steel-making plants, ferroalloy plants, refractory plants, foundries, power plants, etc. Flue gas filtration of waste incinerators, coal-fired boilers, fluidized bed boilers, etc. Asphalt mixing, building materials, cement ceramics, lime, gypsum and other production sites. Smelting flue gas filtration, fine material recovery and liquid-solid separation of aluminum electrolysis, lead, tin, zinc, copper and other rare metals. Liquid solid separation and fine material recovery in chemical, coke, carbon black, dyes, pharmaceuticals, plastics and other fields. Dust treatment and purification collection in mining, grain processing, flour, electronic industry, wood processing and other industries.

The fabric and design of the dust bag should strive to be efficient filtration, easy dust removal and durable. The selection of dust bag is very important, which directly affects the dust removal effect of the dust collector. Two important aspects that determine the quality of the dust bag are the quality of the dust cloth (dust removal material), such as high temperature resistance index, filtration accuracy, and air permeability. On the other hand, the manufacturing process and quality of filter bags are also important factors. Poor manufacturing will lead to powder leakage. So how can we choose a good dust bag?

1. Physical properties:
Such as the mass per unit area, the thickness and amplitude of the bag, the organization of woven fabrics, the density of fabrics, the bulk density and porosity of nonwoven fabrics, etc.

2. Mechanical properties:
Such as the breaking strength and elongation at break of the dust removal bag, the load elongation in the warp and weft directions of the bag, and the bursting strength of the filter material.

3. Dust filtration characteristics:
Such as resistance coefficient, static dust removal efficiency, dynamic dust removal efficiency, dynamic resistance of filter material, regeneration resistance coefficient, dust stripping rate, etc.
We also have many types of dust bags, please contact the dust bag manufacturer if you need.
