A bag filter is used to filter dust and control airflow in raymond mill. Although the bag filter is not a consumable part, it has a certain life in the process of using the raymond mill because of its continuous wear during use.
After the Raymond mill pulverizes the material, it produces strong dust flow and friction, and directly wears the filter bag. The upper part of the dust bag has a low airflow and a small amount of powder. Generally, the bag is broken from the lower part. Wear-resistant fabrics should be the material of dust bag .
Flame-retardant filter media and conductive filter media should be used for the dust bag. Because dust combustion is usually caused by friction sparks or explosion sparks, static sparks, hot particles etc, the charge is the most harmful. Because chemical fiber filter materials are usually easy to charge, and if the dust is charged at the same time, it is easy to generate sparks.
When the weather is wet, the dust will stick to the bag, causing the bag to be ventilated and easy to break under pressure. Before the Raymond mill is turned on, the instrument should be used to tap the dust bag to make the powder accumulated on the dust bag fall off and prolong the life of the dust bag.
Guilin Hengda Mining Machinery Co., Ltd is a professional grinding equipment manufacturer, and HD series high efficiency raymond mill is the hot sell product, here is the features of raymond mill:
1.High capacity and low consumption, the output is increased by 20%-30% compared with traditional Raymond machine, impeller type fan is used, which efficiency is higher than straight blade type fan, once oil can be used for 30-45 days.
2.Powder classification accuracy is higher, without coarseness missing, the accuracy is 80-600 mesh, classification efficiency of 99%.
3.Efficient and stable, grinding roller and grinding ring always contact during operation; environmental protection, low vibration, low noise.
