Raymond Mill Structure And Operation Principle


Raymond mill is widely used in limestone, dolomite, feldspar, barite, calcite, kaolin, gypsum, cement, glass with hardness less than 9.3 fine powder processing, high humidity below 6% in the inflammable and explosive mineral, chemical, construction and other industries more than 280 kinds of materials, Raymond mill product size 80 – 325 orders within the scope of any regulation, part of the material up to 600 head.

Raymond Mill Operation Principle
The material is crushed to the desired size, by the elevator will be sent to the material storage hopper, then through the continuous vibrating feeder will feed evenly into the grinding chamber of Raymond mill host, due to the centrifugal force in rotation, the roller swings outward, tightly pressed on the grinding ring, shovel shovel material to the grinding roller and grinding ring for roll grinding roll and achieve the goal of crashing.

Fine powder material after grinding with the circulating air blower is brought into the analysis of the sorting machine, fine through thick material falling back to re grinding, qualified fine powder with the airflow into the finished cyclone powder collector, the powder discharge tube.

Main characteristics of Raymond mill
1. a wide range of applications, can be aimed at the hardness of less than 6 kinds of materials grinding.
2. under the influence of high pressure spring, the fineness of the finished product is greatly improved.
3. compared with air mill, the system energy consumption is low.
4. less investment, high efficiency, quick recovery.
5. since the system, production links less, less than 25mm of materials can be directly into the machine processing.
6. no pollution, dust removal effect fully meet the national standards.
7. roller grinding device, good sealing effect.
