What is raymond mill?

Raymond mill is a high-efficiency closed-circuit fine powder grinding mill plant for non-metallic minerals. The finished particle size is relatively fine and uniform, and could well meet the material requirements of various fields. It is suitable for processing various non-flammable and explosive minerals with Mohs hardness below 7 and humidity below 6%, such as gypsum, talc, calcite, limestone, marble, potassium feldspar, barite, dolomite, granite, Kaolin, bentonite, medical stone, bauxite, red iron oxide, iron ore, etc., The fineness of the finished product can be adjusted between 613 micron and 44 micron (0.613 mm -0.044 mm) to meet different requirements through adjusting the analyzer and the fan.

Why choose Raymond mill?

1. Raymond roller mill is an efficient closed-circuit circulating powder making equipment. Compared with the ball mill, it has the advantages of high efficiency, low power consumption, small footprint, small investment and no environmental pollution.

2. Raymond grinding mill is vertical structure with small coverage. From raw material rough processing to transportation to powder and final packaging, it can be an independent powder production system.

3.For Raymond mill, its application is mainly in small and medium-sized mines, chemicals, building materials, metallurgy, refractory materials, pharmaceuticals, cement, etc., Baichy machinery could provide great help for the processing of different materials in these industries.

Working principle

Raymond mill is mainly composed of main grinding machine, fineness analysis machine, blower, cyclone, bag dust collector and connecting air duct. According to user needs, Baichy machinery could supply jaw crusher, bucket elevator, vibrating feeder, electric control cabinet and other auxiliary equipment. How does raymond mill machine work? Large rocks are crushed by jaw crusher machine to 0-20mm, and carried by bucket elevator to storage hopper. The crushed rocks by jaw crusher to the needed size are fed into the storage hopper and then they are fed into main raymond mill grinding chamber evenly by vibrating feeder. The grinded materials are blown into analyzer by blower for classification. With the function of impellers and airflow of the fan, materials without meeting fineness are fallen into grinding chamber for grinding again. Qualified powder are blown into a cyclone with airflow through pipelines for collection. The powder from a discharging device is the finished product to packing machine. Separated airflow is back to blower through return duct on the top of the cyclone powder collector.The entire airflow system of this machine is closed and circulating, and it circulates under the condition of positive and negative pressure.
