Domestic Vertical Roller Mill is widely used in cement and silicate products; new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other mineral production industries of all kinds of ores and other grind-able materials can be dry or wet grinding. According to different ways of discharge it can be divided into two kinds of lattice type and overflow type.
How ball mill works
Cylindrical ball Advantages Of Ultrafine Mill is a horizontal rotating device. Material will be fed evenly into the first warehouse where has ladder liner or corrugated liner, built with different specifications of steel balls; centrifugal force will raise the ball to a certain height. After the falling, the material will be seriously impacted and abraded. The material will then enter the second silo which is lined with flat liner for further grinding.
Ore grinding is a crucial procedure in the ore beneficiation plant and the working state of ball mill directly influences the efficiency, energy consumption of the grinding mills of the ore beneficiation plant and the production cost and other technical and economic indexes. To improve the ore grinding efficiency of ball mill, Machinery carries out technical reform from the optimization of the structure of the lining board and the gradation of the steel balls of the milling equipment.
(1) Improvement of the types of lining board
The correlative data indicates that that ball mills with different shapes of lining board will have different ore grinding efficiency. For this reason, it is necessary to choose lining boards with high wear resistance, anti-impact, high strength, high tenacity, high cost performance and high adaptability. The traditional bar-type lining board can be changed to be wave-form groove spiral lining board, which improves the ore grinding efficiency per machine by 6.0% and the utilization coefficient of the grinding mill by 10%.
