MTM Trapezium Grinder

The MTM trapezium grinder absorbs the world first-class grinding technology, elaborate design, by our professional R & D team test and improvement, is currently the most advanced grinding equipment. It has wide applicability, suitable for grinding Mohs hardness below level 9.3, humidity below 6% in various non flammable and explosive mineral materials. In order to improve the yield, we used spring compression device to improve the grinding roller pressure; in order to improve the powder selecting accuracy, it is equipped with a high density of selected impeller powder machine; in order to reduce the vibration and noise, it hosts, powder selecting machine, fan adopts the soft connection; in order to quickly adjust the fineness, it adopts the impeller adjusting device, by changing the selected slot end and shell leaf powder machine between and convenient realization.

The technical performance of MTM trapezium grinder reached the international leading level, compared with the traditional grinding machine has the following five major technical advantage:

Adopted to improve the grinding roller and grinding ring trapezoidal grinding efficiency, the trapezium grinder will rollers and ring is designed into the ladder, reduced into rollers and ring material's slip velocity between, extended to material compaction time, improve the crushing efficiency;

Equipped with high density can improve the powder selecting machine impeller powder selecting accuracy. Practice shows that, at a constant engine speed, improve leaf density can improve the fineness of the product, in other words, the fineness of finished products do not need to change the circumstances, the high density of impeller impeller speed than low density low, reduce the air flow resistance, yield of finished products the same power to improve more than;

High efficient energy-saving centrifugal induced draft fan. The old mill on the traditional straight blade with old fan, and the impeller and blade are energy-saving mould stamping molding draught fan;

Unique design of tilt inward air duct, ensure that enter into the wind nest shell material can be smoothly along the slope into MTM trapezium grinder;

The size of the gap between housing and end of the blade of the powder selecting machine also effects fineness, the machine patent technology is convenient to adjust the clearance.
