Main Configuration of Raymond Mill

Raymond mill is mainly composed of the mill body, analyzer, blower, cyclone collector, and air duct. Among them, the Raymond mill body consists of rack, air-inlet volute, analyzer blade, scraper blade , grinding roller, grinding ring and mill shell.

Superiorities of Raymond mill:

1. Stable rotation and reliable operation.
The transmission device of Raymond mill host is adopted with the sealed gearbox and belt wheel, so Raymond mill can keep the stable rotation and reliable operation.

2. Small footprint
The whole Raymond mill is with the vertical structure. It has relatively smaller footprint, at the same time, it is convenient for users to operate Raymond mill equipment.

3. High screen-pass rate
The screen-pass rate of Raymond mill is as high as 99%. It has the high screen-pass rate that other grinding equipment can't reach.

4. Powerful durability
The important parts of Raymond mill are made of superior castings and profiles. Meanwhile, our technicians manufacture it with sophisticated technology and precise process, so as to ensure the powerful durability of whole-set equipment.

5. Long life-span of its vulnerable parts
The vulnerable parts of Raymond mill are made of high manganese steel with long service life.

6. Easy to operate and maintain
Raymond mill is equipped with the centrally controlled electrical system. The grinding workshop can basically realize unmanned work, which can save the manpower cost for users.  And the maintenance of Raymond mill is also very easy.

Raymond Mill Working Principle:

When the Raymond mill starts to work, we can feed the material into mill body from its feeding hopper. Depending on the grinding roller device hanging on the wobbler spindle, material rotates around the vertical axis, and the material itself is spinning. Because of the centrifugal force effect during the rotation, grinding roller moves outward and squeezes on grinding ring, so that scraper blade can scoop up material to the grinding roller and the grinding ring. Under the roller compaction of grinding roller, the material is completely ground.

Air-separation process of Raymond mill:

After the material is ground into powder, the blower will blow the air into the mill body and blow up the powder. Then the powder is sorted by the analyzer. The powder with too-coarse fineness falls into the grinding chamber and is ground again. The qualified powder enters the cyclone collector with the air. After being collected, the qualified powder is discharged from powder outlet, which is called finished product. The air flow returns to blower through the return duct, and then discharged from the exhaust pipe to the small cyclone collector for purification treatment.
