discription of Raymond Grinding mill

Used for grinding the barite, limestone, kaolin, cerames, and slags below scale 9.3 of Mohs hardness and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industrial, chemical engineering and building material for high fine powder generation and processing

The product size is adjustable in the range of 80 to 325 (600 the largest) meshes

It is possible to product 30 to 80 mesh coarse powder through special device in the machine

Features of Raymond Grinding mill:

The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area

From crushing of raw material to grinding and packing is an independent production system

Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach

Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably

Main parts of the whole plant are made from cast and steel of high quality

The technics is so subtly that insures the durability of whole plant

The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room

Working principle of Raymond Grinding mill:

In the main frame, a 100 to 1,500kg powered pressure spring is fixed to the roller suspender

After the grinder is put into effect, the roller rotates around the main shaft, and rolls closely against the ring pressed by the high pressure spring and centrifugal force

And its rolling pressure ration is 1.2 times higher than that of the Raymond grinder under the same power condition and the production output is raised to substantial degree

When a certain degree of wear of roller and ring is affected, it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring

As a result, the stable output and fineness are ensured
