MTW Grinding Mill

The trapezoidal mill (MTW Grinding Mill) is a new type of mill designed on the basis of the high-pressure suspension roller mill. At present, the trapezoidal mill is mainly used in mining, building materials, chemical industry, metallurgy, coal, and other industries to grind non-flammable and explosive mineral materials with a Mohs hardness below 9.3 and a humidity below 6%. It can be adjusted arbitrarily between 30-400 mesh.

Product features

Stable Performance

Bevel gear overall drive provides strong power. the production capacity increased by 20% under the same power condition.

Economical and reliable

Can grind a variety of minerals to meet the needs of different specifications of particle size; low investment cost, and low operating cost.

Low cost, less maintenance

Patented technology, with an Inner automatic thin-oil lubricating system, and a long oil change cycle.

Low energy consumption

Adjustable output size, efficient powder production. unique air recycling system, together with an advanced dust collector makes the environment much cleaner.

Working principle

Working principle

The trapezoidal mill (MFW Grinding Mill) adopts a trapezoidal working surface, flexible connection, and interlocking pressurization of grinding rollers, which overcomes the defects of traditional industrial mills in terms of scope of application, output, fineness, energy consumption, and service life. The trapezoidal mill adopts trapezoidal grinding rollers and grinding rings that can improve crushing efficiency. The machine designs the grinding roller and the grinding ring in a stepped shape, which reduces the sliding speed of the material entering the gap between the grinding roller and the grinding ring, thereby prolonging the grinding time of the material and improving the crushing effect. The elastic coupling reduces vibration and noise and avoids resonance.
