Product Details

Raymond Mill Introduction:
Raymond Mill usually called raymond pulverizer is a ground-based grinding crushing machinery. Raymond Mill has the advantages of stable performance, convenient operation, low energy consumption, product size of a wide adjusting range, thus widely used in coal, coke, gypsum, limestone, steatite, graphite, bentonite, kaolin, sulfur and pigments, chemical raw materials, chemical fertilizer, pesticide and other fine grinding. Raymond mill's feed size is generally 15 to 20mm, grinding particle size is usually 0.044 -- 0.125mm.

Raymond Mill Working Principle:
After the materials are put into the grinding room of the main equipment, the grinding roll swings outward and presses closely upon the grinding ring due to the centrifugal force in rotation of the main shaft. The shovel carries materials to the space between the grinding roll and grinding ring, and materials are ground as the grinding roll rolls.
After being ground, the powder is selected by Separator via the cycle wind of the blower and the rough powder will be back to the grinding room for regrinding. The proper 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 increased airflow comes out after purification.

Features of Raymond Mill:
1. High Efficiency Under the same finished final size and the same motor power, the capacity of the machine is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
2. Long lifecycle of spare parts The ring and roller are forged by special material with high utilization,the lifetime can reach 2-5 years for grinding calcite.
3. High safety and reliability As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
4. High fineness, flexible adjustment The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm.
5. Environment Protection
