How to replace raymond mill grinding ring?

Raymond mill is a kind of fine mineral powder grinding equipment. It is widely used in barite, calcite, talc, marble, limestone, dolomite, lime, activated carbon, bentonite, kaolin, phosphate rock, Gypsum, glass, manganese ore, titanium ore, chrome ore, refractory materials, insulation materials, etc. The Mohs hardness is below 7, and the humidity is below 6%.

When the Raymond mill is working, the grinding roller makes the grinding ring roll under the action of centrifugal force to crush and grind material, and then achieves the required fineness and output capacity.

The main wearing parts of Raymond mill are grinding roller and grinding ring, which should be replaced in time when the wear is serious, otherwise the output of the equipment will be affected. Compared with the grinding roller, it is very troublesome to replace the grinding ring, especially when the grinding ring is seriously worn.

Dismantle method

1.Remove all grinding roller assemblies,
2.Remove bolts used to fix the grinding roller and cover
3.Use a jack to push out the grinding ring. If the jack cannot be used due to serious wear and tear, it is necessary to cut the grinding ring into several parts by gas cutting, so that the grinding ring can be easily taken out.

Installation method

When installing a new grinding ring, the user needs to do a good job of cleaning to ensure that there is no residue on the inner wall of the air duct, so as to ensure the efficient operation of the Raymond mill.

Replacement frequency

1. Generally, it is necessary to replace the grinding ring once and the grinding roller twice.
2. When the wear degree of the grinding ring is greater than 2cm, it must be replaced, otherwise the efficiency of the air duct will be seriously affected, and the air duct panel is expensive, and replacement is more troublesome.

We need to regularly overhaul the wearing parts and replace the severely worn parts to ensure the best condition of the Raymond mill.
