MTM Trapezium Mill

MTM trapezium mill is mainly applied to the powder processing of mineral products in the industries of building materials, chemical industry, metallurgy, mining, fireproofing, ceramics, iron and steel, electric power, coal, etc.

This MTM trapezium mill is suitable for powder producing from various non-flammable and non-explosive mineral materials with Mohs hardness below 9 and humidity below 6%, such as calcite, barite, petroleum coke, marble, bauxite, manganese ore, iron ore, phosphate rock, dolomite, gypsum, etc.

Technical Advantages

Low comprehensive investment

Three-dimensional structure, complete production line design, small floor area, low original investment.

Excellent damping, sufficient noise reduction, high efficiency and considerate environmental protection

The main mill and powder classifier are combined by braid connection. The damping springs and sealing tapes are used to reduce the vibration and noise and also avoid resonance.

A variety of de-dusting equipments are available, with the emission standard higher than the national standard.

MTM trapezium mill Working Principle

The main mill drives the center shaft to rotate by means of a reducer. The shaft top connects a grinding roller hanger, with a grinding roller device mounted under the grinding roller hanger through the cross arm shaft to form a swinging pivot. The grinding roller rotates around the center shaft of the main mill along the grinding ring. At the same time it also rotates itself under the action of the friction.

The shovel blades system is equipped bottom of the cinquefoil shelf. The shovel blade and the grinding rollers can throw up and feed the materials into the space between the rollers and ring, thus the materials are crushed into powder. The air flow into the grinding chamber from the bottom of the grinding ring takes small particles of powder into the classifier. The coarse particles fall back for further grinding while the qualified powder enters the powder collector along with the air flow and then be discharged from the powder discharging pipes as finished products.
