Introduction of raymond mill

Raymond Mill is a new kind of mill, which is invented with great concentration and on the basis of many years of  powder processing experiences. This invention starts an   epoch of high efficiency and low cost in international mining industry.     

Application of raymond mill

After many years of practice and continuous improvement,  the  structure of  raymond mill   is increasingly perfect, with high efficiency, low energy consumption, cover an area of an area small, less investment and environmental pollution, etc.  Therefore  raymond mill  is widely used in metallurgy, building materials, chemical industry, mines and other minerals in the field of grinding materials processing, suitable for processing mohs hardness under seven, humidity under 6% of all kinds of inflammable and explosive mineral, such as gypsum, talc, calcite, limestone, marble, potassium feldspar, barite, dolomite, granite, kaolin, bentonite, medical stone, bauxite, iron oxide red, iron ore, etc., product fineness 440 microns to 613 microns (0.613 mm to 0.613 mm), through the analysis of the combination of machine and fan, can meet the requirements of different users.

Working principle of raymond mill

After big block materials  are  broken to the required size by by jaw crusher, then the materials are fed into the grinding chamber for grinding by vibrating feeder equably and continuously. The powder after grinding goes upwards together with the airflow, after separating by powder separator, those which can meet the fineness requirement enters into the cyclone powder collector through pipe together with the airflow, and then discharged from the discharge valve as final products. The airflow is sucked into centrifugalblower through wind recycling pipe at the upper part of cyclone powder collector.

The grinded material in the grinding room may contain moisture to some extent, the heat generated during grinding makes the moisture evaporated and changes the air current, and since the pipeline joints are not airtight, the external air is sucked in and the circulation air increases. Thus the balance of the air current can be achieved through adjusting air pipe which is between the air blower and the main engine. The superfluous air current will be led into the bag dust catcher; the fine powder that is along with the air current will be collected. And the superfluous air current will be discharged after being purified.

Features of raymond mill

1. The equipment's structure is tight, from crushing to grinding and packing all together forms an independent production system, it has advantages of covering small area, operating simple, saving work force.
2. The final product has high passing screen ratio, which can achieve 99%. 
3. Driving system of main frame adopts airtight gearing and pulley, which secures reliable operation.
4.  Raymond mill important parts adopt high quality steel, wear-resistant parts adopt high-performance wear-resistant materials, whole machine high wear-resisting performance, reliable operation.
5. Electric system adopts centralized control, milling workshop basic can achieve unattended operation, and convenient maintenance.
