Ball bearing mill VBM series

laboratory

VBM laboratory ball mills are made by lab equipment supplier Vilitek. These ball mills are reliable and highly resourceful equipment for use in laboratories and pilot plants. VBM ball mills are designed for batch operation. They are used both for wet and dry grinding. Vilitek VBM ball mills can grind a wide range of samples of ores and various nonmetallic materials, such as glass, ceramics, minerals, ferrous and non-ferrous ores, alloys, chemicals, vegetable stock, soils, sewage sludge, and others. VBM mills are perfectly suited for sample preparation, production of batches of materials in pilot plants, research on grind ability of materials in various modes and studies using Bond technique. The ball mill works on the following principle: size reduction is achieved by impact from metal balls in a rotating drum. The drum is loaded with grinding material and balls. When rotating, the material is crushed as a result of abrasive effect, chipping action and impact force. As a rule, the optimal grinding time, rotation speed, number and size of balls, and the grinding type are selected experimentally for each specific material – depending on its properties, quantity, and granularity of the initial fraction. At the end of the grinding cycle, the product is unloaded together with the balls into a receiving container, where they are separated. Unloading and separation can be done at the same time when using a special unloading cover, which is supplied together with each ball mill in the series.
