In modern industrial production, the material fineness required by different industries and application areas is also different. Nowadays, modern technology is constantly developing, and we have higher fineness and efficiency requirements for grinding equipment. However, since the fineness of materials used in different industries varies with specific needs, it is not said that the finer the powder of the material is better.

Under normal circumstances, we divide the fineness range into three stages: coarse powder processing (0-3mm), fine powder processing (20-400 mesh), and ultrafine powder processing (400-3250 mesh). Among them, 400 mesh powder is widely used in some fields.

Then, if you are processing 400 mesh grinding powder, is there any recommended equipment?

Raymond grinding mill

Guilin Hengda Minging Machinery Col., ltd HD series raymond grinding mill breakthrough the bottleneck of the grinding mill, the processing capacity is 30% high than the capacity of the R type raymond mill. It has the advantages as following.

HD Series Raymond Grinding Mill features:

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.
