Overview
MTM series trapezium mills are a stable grinding equipment, which are generated and practicle used with more 30 years for producing 80-325 mesh mineral powder. Features less investment and adaptability to materials, MTM mills are very popular with customers.
Features
1. Less Occupied Area & Less Investment
MTM series trapezium mills has its own production system from bulk material to finished powder, with less investment in building plant and foundation.
2. Adjustable Output Fineness
MTM series trapezium mills adopts modular impeller adjustment device, which can produce products with different fineness only by changing impellers.
3. 60% Lower on Consumption than Ball Mill
MTM series trapezium mills has an energy consumption of more than 60% lower than that of the same grade of ball mill under ideal working conditions.
4. Higher Induced Air Efficiency
MTM series trapezium mills adopts high efficiency impeller fan, which improves the efficiency of air induction from 62% to 85%.
Working Principle
The host drives the central shaft running (Fig. 3) by the gear box. The upper end of the shaft is connected with a wobbler spindle and the grinding roller is suspended under the wobble spindle by a cross arm shaft and forms a swinging point. The grinding roller runs along with the central shaft of the whole machine, and also rotates by friction with the grinding ring. A perching knife system is installed under the wobble spindle and feeds the material into the gap between the grinding roller and ring for pressing and grinding with the grinding roller during rotation. (Fig. 5) Air flow will bring minor powder into the powder concentrator upon entry into the grinding gravity from the bottom of the grinding ring. Coarse materials fall down and are reground; and fine powder goes into the powder collector along with the air flow and is discharged as the finished product through the powder discharge tube.
