Raymond Mill



  • Raymond Mill is getting more and more perfect by low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional grinder mill after many years of practice and improvement. Currently, the most popular Raymond mill in the leading position are on the basis of Newell Company and occupies 70% market share. Raymond mill’s production and the development has closely related to the development of scrap industry.
  • Raymond Mills are mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. Raymond mill can produce powder from more than 280 kinds of non-flammable and non-explosive mineral materials with Mohs hardness below 7 and humidity below 6%, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum etc. The final size of the raymond mills is between 613 micron and 440 micron(0.613mm—0.044mm). Through the function of separator and blower, raymond mill can meet different customers’ demand.

How Does Raymond Mill Work?

  • Firstly, raw material is crushed by jaw crusher to the size required, and then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind. After this, the ground stuff is carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The airflow system is closely sealed up and circulated under condition of negative and positive pressure.

Raymond Mill Characteristics

  • 1. The whole plant of the grinder mill is a vertical structure of strong systematic characteristic, so the raymond mill occupies small area. From crushing of raw material to grinding and packing is an independent production system.
    2. Compared with other milling plants, raymond mill's passing ratio achieves 99%, this is what other grinder mill can not reach;
    3. Driving system of the raymond mill's main frame adopts airtight gearing and pulley, drives smoothly and operates reliably;
    4. The electric control system of the grinder mill is centralized controlled, so the automaticity is high, no people are needed in the operating room.
    5. Main parts of the whole raymond mill plant are made from cast and steel of high quality. Such strict techniques insure the durability of whole plant.

Raymond Mill Maintenance Knowledges

  • Prior to installation of the raymond mill equipment, all the people who will be assigned to operate the equipment have to be technically trained to know the principle and rules of its operation. Someone should be specially selected and put in charge of the raymond mill's operation.
  • In order to enture raymond mill in a normal working state, a Safety Operation System for the Maintenance of the grinding equipment must be established. Only in this way can this raymond mill be guaranteed to have a long-term and safe operation. Meanwhile, it is necessary to have the required repairing tools, lubricant and grease, spare parts and accessories.
