Raymond Mill

raymond mill machine is widely used in mineral products, building materials, chemical industry, metallurgy and materials in the field of mine etc. The material after crushing to the desired size, by the elevator materials will be the to the storage hopper, then through vibrating feeder will feed into the uniform continuous grinding room host, due to the effect of centrifugal force of the rotating, grinding roller swing outwards, pressed on the grinding ring, blade material to scoop up between rollers and ring because of the grinding roller, rolling and achieve the purpose of crushing.

Applications: Metallurgy, chemical engineering, building materials, mining, pharmacy, cosmetics and other fields

Raymond Mill's Requirements On Materials

Moh’s hardness below Grade 7
Moisture below 8%
Non-combustible and non-explosive
Feed size ranging from 40 to 400meshes

Imported high-quality steel is used for important parts. High-performance wear-resistant materials are used for the grinding parts.
A Raymond Mill covers a small area, and can complete powder preparation efficiently and the fineness of the finished product is uniform and the screening rate can be as high as 99%;

How raymond mill processing material

Powder after grinding with circulating air blower is brought into the sorting analysis machine, fine through thick materials fall back to the grinding, qualified fine powder with the airflow into the finished cyclone powder collector, the powder tube.

what raymond mill should pay attention to in debugging process

Raymond Mill no-load start, to be in normal operation and loading. And then observe their smooth operation, no abnormal noise and vibration of rolling bearing, the highest temperature of not more than 70℃, temperature shall not exceed 35 C.
Raymond mill load transportation time not less than 8 hours, the normal work of Raymond mill after the machine without abnormal noise, the pipe joints without leakage phenomenon, after the test machine again after the solid screw, can be put into normal use.
Raymond mill low pressure springs, Raymond mill grinding roll of material is also bigger , its yield is also higher, but should be based on the loading condition of the Raymond mill main motor, Raymond mill grinding roller is with small gradual compression. The pressure spring height should be controlled in the range of 200 ~ 210 mm range.
Raymond mill should empty load operation test machine, in the no load test machine, Raymond mill grinding roller device should be used for steel wire rope wrapped tightly, avoid Raymond mill grinding roller and grinding ring contact impact, then host idle test machine is not less than 1 hours; the host operation should be smooth, the box body temperature is not too high.
