Raymond Mill's dust bag method

The role of Raymond's dust bag is to filter dust or to control the air flow. It is not a wearable part in the raymond mill system. However, the dust bag is worn during use, so it also has a service life.
Raymond Mill dust bag used as follows:
1. When the material is crushed by Raymond Mill, the resulting dust flow and friction are strong, will directly wear dust bag, reduce service life. In the common dust, aluminum powder, silicon powder, coke powder, charcoal powder, sintered ore powder and other high-loss dust, Raymond machine users should choose a good wear resistance of the filter fabric. According to the experience, the wear parts of the dust bag are concentrated in the lower part of the dust bag, because the upper air flow rate of the dust bag is low and the dust concentration in the gas is low, so the wear probability is relatively low.
2. Sometimes the dust on the dust bag will also be burned and burned out of the dust bag. Dust burning is usually caused by friction spark or explosion sparks, static sparks, hot particles, etc., which charge the greatest harm. This is because the chemical fiber filter is usually easy to charge, if the dust at the same time charge is easy to produce sparks, so for flammable and easy charge of dust, etc., should choose flame retardant filter and conductive filter.
3. When the weather is humid and the moisture content in the air is high, the powder on the dust bag is easily reunited with small water molecules, and it takes a long time to accumulate. The dust bag can not be ventilated. It will be under the action of air pressure was broken. So, every day after the repair of the mechanical parts of raymond mill, but also need to beat the dust bag with a stick, so that the powder accumulated in the dust bag off to extend the life of dust bag.
