Product Description
The Great Wall Raymond mill is used to grind materials in the fields of buildingmaterials, mining, metallurgy and chemical industry. The materials must benon-flammable and non-explosive materials such as: limestone, calcite, barite,dolomite, potassium feldspar, marble, talcum, gypsum, kaoline, medical stone,rock phosphate, manganese ore, iron ore, glass, ceram, active carbon, carbonblack, fireproof materials, heat preservation materials, chemical materials andso on(300 kinds of materials). The materials should have the hardness less than7 in Moh's scale and humidity less than 6 percent. The granularity of the endproducts can be adjusted from 30 to 325 meshes.
Working Principle:
After the materials enter the grinding chamber of the main frame, thegrinding roller swings outward and presses closely upon the grinding ring due tothe centrifugal force generated by the rotation of the main shaft. The bladecarries materials to the space between the grinding roller and grinding ring,and materials are ground as the grinding roller rolls.
After being ground,the powder is selected by classifier via the cycle wind of the blower and therough powder will be back to the grinding chamber for regrinding. The qualifiedpowder is brought into the powder collector together with airflow. The powdercomes out as end products while the airflow goes back to the powder collector incycling to make the machine work normally. The remained airflow comes out afterpurification by dust filter.
