Application of Raymond Mill

SHIBANG Raymond Mill is applicable to the grand processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 mesh to 325 mesh according to requirements.

Structural Characteristics of Raymond Mill

The whole grinder Mill is of a standing structure. Raymond Mill features small occupying space and strong integration capacity. Raymond Mill can form an independent production system from the lump materials , crushing to finished powder and packaging.

All the finished particles have a good uniformity of fineness, with passing screen rate as high as 98%. This is what other machine cannot reach. The machine adopts electromagnetic vibrating feeder, which ensures even and regular feeding.Raymond Mill is easy to adjust, small in dimension, light in weight, with lower oil and power consumption and easy to maintain.

The transmission device of the main unit is equipped with a close gearbox which ensures its smooth transmission and reliable operation. Attendance of operater is not necessary in the Mill operating room because the adoption of advanced central control console switch.

Factors Influencing Raymond Mill Capacity

Major factors affecting the capacity of any given roller mill include desired fineness, grindability and initial moisture. The capacity of the mill decreases when fineness increases. The harder a material is to grind, the lower the capacity of the mill. High initial moisture may also decrease mill capacity because of limitations on the drying capacity of the mill.

The roller mill, when equipped with a variable speed mill drive, can be used in applications requiring adjustable capacity. This allows the user to match product rate with downstream process requirements, thereby reducing the operating and maintenance problems associated with frequent starts.

Maintenance and Repairof Raymond Mill

1. Prior to installation of the equipment, all the people who will be assigned to operate the equipment have to be technically trained to know the principle and rules of operation. Someone should be specially selected and put in charge of the operation.

2. To ensure normal operation of the equipment, a manual containing strict rules and procedures for its operation, maintenance and repair should be well prepared and followed. Tools, replacement parts for maintaining, repairing and lubricating oil and grease must be available for immediate use.

3. After a period of usage, the equipment should be checked, to replace worn-and-torn parts such as rollers, rings and shovels. Be sure to fasten connecting-bolts, nut collars to fix rollers properly. Be sure to lubricate the parts sufficiently.

4. Roller should be replaced after 500-hours use. To check bearing in them and replace broken ones, and then fill enough oil and grease (with oil-pump or grease-gun).
