Overview Of MTM Medium Speed Trapezium Mill↑

MTM Medium Speed Trapezium Grinding Mill machine is designed by our own engineers and technical workers to overcome the traditional Grinding Mill machine defect completely in application, capacity, fineness, energy consumption, service life, etc.This series of Grinding Mill has become a leading-world-level industrial mill.It adops numbers of national national patents and world-leading-powder processing technology, such as trapezium’s working surface, flexible connection, roll linked pressure boost, etc.Now MTM Medium Speed Trapezium Grinding Mill is the ideal substitute of the traditional mill, such as Raymond mill, high pressure suspension grinding mill, ball mill, etc.

The Application Of MTM Medium Speed Trapezium Mill↑

MTM Medium Speed Trapezium Mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. It can produce powder from non-flammable and non-explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum, trona, beads etc. The final size is between30â

The Features & Benefit Of MTM Medium Speed Trapezium Mill↑

• The ladder-shaped rollers and rings improve crushing efficiency greatly. The rollers and ring are designed in the main machine of an inverted trapezium, which control the material’s slip velocity between rollers and rings. They can extend the grinding time, and enhance the crushing effect.
• The press springs with balancing and pressurized function and the forming resilient connection with steady and vibration reducing function are invented into our machines. The symmetrical roller assembly is connected by horizontally-placed spring rod. When the large materials impact one roller assembly, to keep balance, the radial force will pass to another roller assembly, which is on the plane of symmetry through spring rod. Under this condition, the whole device’s bearing is improved to be 40% on the other mills; and the forming resilient connection can reduce the vibration and noise, also it can avoid resonance.
• The powder classifier adopts high density impeller, which can increase precision of powder and capacity. It has been proved that: under fixed spindle speed, to enhance the density of impeller is to enhance the fineness of final products. In other words, when the fineness of final product is fixed, the spindle speed of high density impeller is lower than the low density one. Thus under the same power, our machine can reduce resistance of air’s flow, the capacity can be improved more than 50% over the traditional one.
• There is high-efficiency and energy-saving blower installed on our machine. The efficiency of prismatic blade equipped on the traditional machine is only 62%, but the efficiency of the energy saving blower, whose impeller and blade are both stamping, is 85%.
• There is convenient impeller adjusting device. The clearance between housing and ending of powder classifier’s blade also effects fineness. Our mill is convenient to adjust the fineness. Construct

Main Parts Of MTM Medium Speed Trapezium Mill↑

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.

Working Principle Of MTM Medium Speed Trapezium Mill↑

Inside the MTM Medium Speed Trapezium Grinding Mill machine,air is driven into the undersurface of the grinding ring. The air entering the MTM Medium Speed Trapezium Grinding Mill machine flows upward, carrying fines to the classifying section. The classifier allowed the pulverized material to pass. The oversized particles are drove back to the grinding chamber for further processing. The service life of major mechanica components can be extended because the whole MTM Medium Speed Trapezium Grinding Mill machine operates under negative pressure conditions.Thus minimizing mill maintenance and plant housekeeping problems have been solved.

Maintenance Of MTM Medium Speed Trapezium Mill↑

1. Prior to installation of the equipment, all the people who will be assigned to operate the equipment have to be technically trained to know the principle and rules of operation. Someone should be specially selected and put in charge of the operation.
2. To ensure normal operation of the equipment, a manual containing strict rules and procedures for its operation, maintenance and repair should be well prepared and followed. Tools, replacement parts for maintaining, repairing and lubricating oil and grease must be available for immediate use.
3. After a period of usage, the equipment should be checked, to replace worn-and-torn parts such as rollers, rings and shovels. Be sure to fasten connecting-bolts, nut collars to fix rollers properly. Be sure to lubricate the parts sufficiently.
4. Roller should be replaced after 500-hours use. To check bearing in them and replace broken ones, and then fill enough oil and grease (with oil-pump or grease-gun).
