MTM medium speed trapezium mill outline

MTM medium speed trapezium grinder mill is a leading-world-level industrial grinder mill. It is designed by our own engineers and technical workers, basing on industrial mill research of many years and adopting world-leading-powder processing technology.

This type trapezium mill adopts numbers of national patents, such as trapezium working surface, flexible connection, roll linked pressure boosts etc. It has completely overcome defects of traditional mill in amplification fields, capacity, fineness, energy consumption and service life etc.

Components of grinding line: The whole set of MTM medium speed trapezium mill consists of main unit, powder classifier, cyclone collector, decelerator, dust catcher, blower, motor, and pipes. The optional accessories include jaw crusher, elevator, feeder, and control cabinet.
MTM medium speed trapezium mill features

1. The trapezium shaped roller and ring highly improved the crushing efficiency.
2. The pressure springs work the function of balance and pressurize. Elastic connection can reduce vibration and keep balance when the equipment works.
3. The powder classifier adopts high density impeller which can increase powder precision and capacity.
4. Adopting high-efficiency and energy-saving blower.
5. Using convenient impeller adjusting device.
MTM medium speed trapezium mill operating principle

In the grinding mill, air is driven into the undersurface of the grinding ring and flows upward, carrying fines to the classifying section. The classifier allowed the pulverized material to pass and the oversized particles are drove back to the grinding chamber for further processing. The whole mill operates under negative pressure conditions, which can maximize the service life of major mechanical components. Thus minimizing mill maintenance and plant housekeeping problems have been solved.
