High efficiency vertical roller mill

Three-dimensional structure. The screen-passing rate can reach to 99%. The transmission device of mainframe adopts airtight gear case and zonal wheel. Centralized control for the electric system, convenient to operate. Produces and processes fine powder. The product size is adjustable from 80 meshes to 425 meshes. It is possible to produce 30 - 80 mesh coarse powder through a special device in the machine. Working principles of High efficiency no pollution Raymond mill. The materials enter the grinding room of 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.

A new type of Mini Raymond Mill Not long ago, Our Company's experts on the basis of the former mill , invented a new type of grinding mill-Vertival Roller Mill. The following is a brief introduction on the vertical roller mill. Vertical roller mill is on purpose to grind mining materials in the fields of metallurgy, building materials, chemistry, mining and so on. It can grind the non-flammable and non-explosive mineral materials with the Moh's hardness lower that scale 9.5 such as quartz, feldspar, calcite, talcum, barite, fluorite, rare earths, marble, ceram, bauxite, manganese ore, iron ore, copper ore, phosphate rock, colcothar, zircon, slag, cement clinker, dolomite and so on.

Vertical Roller Mill Working Principle: The motor dives the grinding table to turn through the speed reducer. At the same time, hot air comes into the roller mill from the air inlet. The materials fall down the centre of grinding table from the feeder. Because of the centrifugal force, the materials move to the edge of grinding table from the centre . The materials are crushed by the grinding roller when they passes the groove on the grinding table. The crusher materials continue to move to the edge of the grinding table until they are taken away by the airstream. Then the bigger materials fall down the grinding table and the process of crushing continues. When the materials in the airstream pass the separator on the top of the mill, the materials fall down the grinding table from the taper filler under the force of guide leaf blade. The fine powder comes out with the airstream, and is gathered by the dust catcher of the system. The powder gathered is the final product of roller mill.
