Raymond Mill

Raymond Mill is a high-fine powder equipment suitable for high-efficiency closed-circuit circulation in mining, chemical, building materials, refractory materials, metallurgy and other industries. Raymond mill is widely used in barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass. High-fine powder processing of more than 280 kinds of materials, such as non-flammable and explosive ore, chemical, building materials and other industries with a Mohs hardness of not more than 7 grades and a humidity of 6% or less. The finished product has a particle size of 50-325 mesh. Arbitrarily adjusted, some materials can be as fine as 600 mesh.

product description

Technical performance and characteristics

High screening rate, strong systemicity

Raymond mill uses a three-dimensional structure, with a small footprint and a strong system. It is a self-contained production system from block to finished product. The fineness of the finished product is uniform and the screening rate is 99%, which is difficult for other milling equipment. The transmission adopts a closed gear box and pulley, which makes the transmission smooth and reliable.

Centralized control

The electrical system adopts centralized control, and the grinding workshop can basically realize unmanned operation and convenient maintenance. The important parts of Raymond mill are made of high-quality steel, and the wear parts are made of high-performance wear-resistant materials. The whole machine has high wear resistance and reliable operation.

working principle

After the Raymond mill crushes the bulk material to the required feed size, the bucket elevator transports the material to the storage bin, which is then sent by the electromagnetic feeder to the grinding chamber of the main machine to enter the grinding chamber. The material in the grinding is ground between the grinding roller and the grinding ring. The powder after grinding is brought to the analysis machine by the fan airflow. The fine powder that meets the fineness is sent to the large cyclone collector through the airflow for separation and collection. And then discharged through the unloader is the finished product.
