R-type Raymond Mill, Raymond Mill Manufacturer

R-type Raymond millWidely used in the grinding process of mineral materials in metallurgy, building materials, and mining industries, processing Mohs hardness.Non-flammable and non-explosive minerals below grade 9 and with humidity below 10%, such as talc, gypsum, calcite, limestone, potassium feldspar, barite, dolomite, granite, kaolin, bentonite, bauxite, ferric oxide, iron ore, etc., with finished particle fineness ranging from 80 to 800 microns, can meet various customer requirements through the combined action of analyzers and fans.
Advantages
1. The Raymond mill features a compact, three-dimensional structure with a small footprint and high integration. It forms an independent production system from raw blocks to finished powder.
2. The finished powder has uniform fineness, with a sieve pass rate of 99%, which is difficult to achieve with other powder grinding equipment.
3. The main drive unit of the grinding mill adopts an enclosed gear box and belt pulley, ensuring smooth transmission and reliable operation.
4. The Raymond mill's critical components are made of steel, wear parts are made from high-performance wear-resistant materials, ensuring the entire machine has high wear resistance and reliable operation.
5. The electrical system employs centralized control, allowing the coal powder workshop to be largely unmanned and easy to maintain.
6. Full system hermetically sealed vacuum circulation, free from dust pollution and noise, environmentally friendly and safe.
7. Equipped with an electromagnetic vibration feeder for even feeding, automatic feeding, easy adjustment, compact size, light weight, and easy maintenance.
Operating Principle
The solid material is crushed to a certain particle size, then lifted vertically into the storage hopper by a hoist. The electromagnetic vibration feeder then feeds the material into the main machine in a quantitative and uniform continuous manner for grinding. The powdered material is blown out by a blower and extracted by a classifier placed above the main machine for grading. The finely ground powder that meets the specifications is carried by the airflow into a large cyclone collector, collected, and discharged through the powder outlet as finished product. The airflow enters the blower through the return pipe at the top of the large cyclone collector. The entire air distribution system operates in a closed-loop and under a negative pressure condition.
Due to moisture content in the material being ground, which evaporates into gas during the grinding process, and the introduction of some air during the feed, the air volume in the circulating air path increases. The excess air enters the dust collector through the exhaust duct at the front of the blower, along with the fine dust carried by the exhaust air, which is then collected by the dust collector. The clean gas separated by the dust collector is released into the atmosphere.
