MTW Trapezium Mill

Brief introduction:Trapezoidal grinding machine is widely used in power, mining, metallurgy, stone industry, iron and steel, building materials, coal and other industries.It is mainly used for grinding various non-flammable and explosive mineral materials with mohs hardness below grade 9 and humidity below 6% in mining, building materials, stone industry, metallurgy, thermal power and coal industries.The fineness of finished product can be adjusted at 30-400 mesh.

Application: In addition to limestone desulfurization, the new environment-friendly and energy-saving grinding mill is also used in mining (stone powder making), slag, fly ash, slag, building materials (paint, high grade paint, highway, mixing station, ceramics, glass, etc.), petroleum exploration, non-ferrous metal processing, stone industry and other industries.

MTW European Type Trapezium Mill--- the latest type of Raymond Mill, has become one of the most advanced grinding mills in the world with its so many intellectual properties like bear-gear drive, inner oil lubricating system, arc air channel, etc.

Product Feature

1、 The whole bevel gear transmission has low energy loss and high efficiency.

2、Specially designed roller and ring, replaceable curved blade, high efficiency and low cost.

3、 Roller joint pressurization device, stable operation and advanced productivity.

4、Reliable and advanced internal automatic thin oil lubrication system technology is adopted.

5、 Humanized design makes it easy to use.

Working Principle

The main engine of MTW series European trapezoidal grinding machine drives the central shaft to rotate through the integral transmission device of bevel gear. The upper end of the shaft is connected with the suspension rack of grinding roller, which is equipped with the grinding roller device and forms the swing fulcrum.The grinding roller device not only revolves around the central shaft, but also revolves around the grinding ring. The grinding roller itself rotates due to friction.A spatula is installed under the grinding roller hanger, which is located at the lower end of the grinding roller. In the process of the rotation of the blade and the grinding roller, the material is thrown up and fed into the grinding ring of the grinding roller, forming a cushion material layer.
