Detailed Description

Raymond Grinder has almost several tens of years history. Raymond Mill Machine is collocated with jaw crusher, elevator, electromagnetic vibrating feeder, main unit, classifier, collector, cloth deduster and high-pressure blower and so on. We also offer spare parts and original wear parts related to the Raymond Mill. After years of practice and improvement by manufacturer Shanghai Dingbo Machinery, the structure of Raymond Mill is getting perfect by blow consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional industrial grinding mill. The Raymond Grinding Mill is used to grind materials in the fields of building materials, mining, metallurgy and chemical industry. The materials must be non-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, carbon black, fireproof materials, heat preservation materials, chemical materials and so on(300 kinds of materials). The materials should have the hardness less than 7 in Moh's scale and humidity less than 6 percent. The granularity of the end products can be adjusted from 30 to 325 meshes. Working Principle: After the materials enter the grinding room of the main equipment, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roll 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 the rough powder will be back to the grinding room for regrinding. The qualified powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally. The remained airflow comes out after purification by dust catcher.
