The Handling Materials of Raymond Mill:
Raymond mill, also called Raymond grinding mill. It is suitable for producing powder in mineral, chemical, building and other industries. 

Raymond Mill is suitable for grinding of all kinds of materials whose Moh’s hardness is below 9.3, such as calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, clay, white mud, mica, refractory material, glass, total about ***0 kinds of materials.

Internal structure and Working Principle of Raymond Mill:

The standard configuration of Raymond Mill consists of main unit, reducer, powder classifier, cyclone powder collector, dust cleaner, blower, control cabinet motor and pipes. The optional accessories include crusher, bucket elevator, feeder.
Big materials are crushed by jaw crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and are fed evenly and continuously by vibrating feeder into the main unit for grinding. The grinded powder are carried by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter cyclone collector through pipe, and are separated and collected there. They are discharged at the discharging valve to become finished products; The airflow is sucked to the blower by return pipe on the top of cyclone collector. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure.
Benefit of Raymond mill 
1.Ertical structure, so it has small footprint, strong system. 
2.Compared with other mills, Raymond Mill has high passing rate - *9%.
3.Adjustable particle size:*****5mesh
4.The main drive device of Raymond mill adopts airtight gear box and belt pulley, the transmission is stable and the operation is reliable.
5.Important components are made of high quality castings and profiles, ensuring the durability of the whole equipment.
6.The centralized control is used in the electric system, the mill can basically realize unmanned operation, and the maintenance is convenient.
