R-Series Roller Mill

Raymond Mill - the originator of Pendulum Grinding Mill

The R series pendulum mill belongs to the classic Raymond mill series with high cost performance. The Hongcheng R-type machine has been optimized and upgraded in technology, and its performance has been greatly improved in all aspects. The parameter configuration has been well tested by the market for a long time. It has been confirmed that it is an economical and applicable choice for small and medium-scale non-metallic ore milling.

R-Series Roller Mill

This product is suitable for grinding limestone, calcite, talc, dolomite, bauxite, marble, feldspar, barite, phosphate rock, coal mine, clay, kaolin, wollastonite, lime, bentonite, etc. , and other all kinds of non flammable and explosive materials with Mohs hardness below 7 and moisture below 6%.

Working Principle

working principle:

The raw materials with suitable particle size are fed into the main machine through the feeding mechanism (vibration feeder, belt feeder, screw feeder, air lock feeder, etc.); the high-speed rotating grinding roller rolls tightly under the action of centrifugal force Pressed on the grinding ring, the material is shoveled by the shovel and sent to the grinding area formed by the grinding roller and the grinding ring. The material is crushed into powder under the action of the grinding pressure; After blowing through the sorting machine, the materials that meet the requirements of fineness pass through the sorting machine, and the materials that do not meet the requirements are stopped by the sorting machine and return to the grinding chamber to continue grinding; the sorted qualified materials are blown into the cyclone through the pipeline. The collector separates the material and gas through the action of the cyclone. The collected material is sent to the next process through the unloading valve. The separated airflow enters the main engine under the action of the fan and participates in the next cycle; the unloading valve below the cyclone collector , it can be directly bagged and packaged by the packaging machine, or directly loaded and transported by the bulk machine, and can also be sent to the finished product warehouse through the conveying mechanism for storage; after the excess air in the system passes through the pulse dust collector, it is discharged into the atmosphere to ensure the stability of the system. The collection efficiency of the pulse dust collector reaches 99.99%, ensuring that the discharge meets the environmental protection standards.
