The Raymond Mill(Pulverizer) is an excellent grinding device for
materials used in the fields of building materials, mining, metallurgy and
chemical industry which is not flammable and non-explosive as well. Such materials include 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.

At first required materials to grinded enter the grinding chamber of the main frame, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roller and grinding ring, and materials are ground as the grinding roller rolls.
After being ground, the powder is selected by classifier via the cycle wind of
the blower and the rough powder will be back to the grinding chamber for
regrinding. The qualified powder is brought into the powder collector together
with airflow. The powder comes out as end products while the airflow goes back
to the powder collector in cycling to make the machine work normally. The
remained airflow comes out after purification by dust filter.
