Usage and Application
The Raymond mill is used to grind materials in the fields of building materials, mining, metallurgy and chemical industry. The materials must be non-flammable and non-explosive materials such as: limestone, calcite, barite, dolomite, potassium feldspar, marble, talcum, gypsum, kaoline, medical stone, rock phosphate, manganese ore, iron ore, glass, ceram, active carbon, carbon black, fireproof materials, heat preservation materials, chemical materials and so on(300 kinds of materials). The materials should have the hardness less than 7 in Moh's scale and humidity less than 6 percent. The granularity of the end products can be adjusted from 30 to 325 meshes.

Features

1. The whole mill is of spatial structure , less premise and systemic strong. The whole system from roughing, transportation, powder collecting to packaging forms a independent production system. 
2. Even granularity, sieving rate 99%, which is unapproachable for other mills. 
3. The driving device applies inclosed gear box and belt pulley, so the transmission is calm and the operation is reliable. 
4. All the main parts of Raymond Mill adopt high quality steel, the resistant parts use high-performance proof materials, so the whole system has high wear resistance and reliable performance. The blade frame of the main machine keeps in touch with the materials , it is consisted of the upper part and lower part, when the lower part is worn down , just take down the bolts to exchange it . 
5. Centralized controlling of the electrical system, unmanned operation , easy maintenance. 
6. Less dust pollution, low noise.
