Product introduction

Raymond mill is a leading word level industrial mill is designed by our engineers and technical workers, basing on many years industrial mill design, adopting world leading powder making technology. Our machine adopts numbers of national patents of mill, such as trapezium working surface, flexible connection, roll linked pressure boost, etc. It has totally covered many defects of traditional mill, like application, capacity, fineness, energy consumption, service life, etc and it is the ideal substitute of traditional mill, such as high pressure suspension mill, ball mill, etc.

Performance features

1. 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.

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

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

4. Main parts of the whole plant are made from cast and steel of high quality. The technique is so subtly that insures the durability of whole plant.

5. The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room and it's easy maintenance.

Working principle

General: Crushing -- Grinding -- Selecting -- Collecting

Detailed: Materials first enter jaw crusher to be crushed to smaller size. Then they are lift to storage room by elevator. Vibrating feeder will feed materials into grinding room evenly.

When the materials are put into the grinding room of the main equipment, the grinding roll swings outward and presses closely upon the grinding ring due to the centrifugal force in rotation of the main shaft. The shovel carries materials to the space between the grinding roll and grinding ring, and materials are ground as the grinding roll rolling.

After being ground,the qualified powder is selected by Separator via the cycle wind of the blower and the rough powder will be back to the grinding room for regrinding. The qualified powder is brought into the powder collector by airflow. The powder comes out as end products.
