MTM Medium Speed Trapezium Grinding Mill Overview
grinding millMTM Medium Speed Trapezium Grinding Mill is designed by our own engineers and technical workers to overcome the traditional grinding mill 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.
MTM Medium Speed Trapezium Grinding Mill Parts
The whole set of MTM medium speed trapezium grinding mill consists of main mill, powder classifier, speed reducer, blower, jaw crusher, bucket elevator, vibrating feeder, storage bin, bag filter, pipe and fitting, cyclone powder collector, electric control cabinet, electric motor, etc.
MTM Medium Speed Trapezium Grinding Mill Application
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 etc. The final size is between30—400mesh. Fully considered the needs of desulfurization, MTM Medium Speed Trapezium Mill could perfectly work with desulfurization equipments to increase the efficiency of desulfurization. So it is the best choice of desulfurization
MTM Medium Speed Trapezium Grinding Mill Main Features and Benefits
  1. The crushing efficiency is improved highly thanks to the trapezium shaped roller and ring of the MTM Medium Speed Trapezium Grinding Mill.
  2. When the MTM Medium Speed Trapezium Mill works,elastic connection can reduce vibration and keep balance when the equipment worksand and the pressure springs work the function of balance and pressurize.
  3. Powder precision and capacity increases because the powder classifier adopts high density impeller.
  4. Adopting high-efficiency,energy-saving blower and using convenient impeller adjusting device make our MTM Medium Speed Trapezium Grinding Mill have better capability.
  5. Using convenient impeller adjusting device.
MTM Medium Speed Trapezium Grinding Mill Working Principle
Inside the MTM Medium Speed Trapezium Grinding Mill,air is driven into the undersurface of the grinding ring. The air entering the MTM Medium Speed Trapezium Grinding Mill 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 operates under negative pressure conditions.Thus minimizing mill maintenance and plant housekeeping problems have been solved.

MTM Medium Speed Trapezium Mill use and maintenance of common sense
  1. The spindle refueling time should for each class plus, but it should be noted that the oil found in oil-cup there is no loss or loss is too slow, they should immediately wash the oil Road, together with 50 # machine oil, oil cup top position in the spindle, spindle base bearings, roller bearing axle with grease gun for each class notation 3 # lithium based grease once a parser bearings cleaned once every six months apart, add a little 3 # lithium based grease, fan bearings room plus lithium Grease.
  2. Forbidden piece of metal into the machine, otherwise it will damage grinding roller and grinding ring, and even center hanger and so on.
  3. Feeding should be uniform, non-erratic. feeding too much will be blocked duct, lower output, easy to burn out motor, feeding too little is not good also. Feed size: hard material in the diameters less than 15 mm, preferably, soft material diameter of 20 mm, large pieces of material is strictly prohibited to join the machine.
  4. Air volume control: in the fan on the intake manifold air flow control valve, generally open to maximum position, according to fineness, yield requirements appropriate adjustments. Is located in the exhaust pipe on the exhaust exit control valve, transferred to feed the mouth can be no dust emitted. Air volume is small, thin high. It should be noted, wind is too small, the host within a duct beneath the easy precipitation of materials, please be adjusted appropriately.
  5. Fineness adjustment, according to materials, size, hardness, moisture content, the proportion of different degree of processing of different thickness, adjustable top of the analyzer, high speed, fineness high, speed low, thin low. Improve the fineness, the output will be reduced accordingly, if it is mainly the fan speed when debugging, the user can flexibly.
  6. When the ball mill is running , it should be checked whether the barrel body leak,where the feeding water or ore is normal,where the electric current and voltage is normal.If there is some proble,it should be handled quickly.
  7. Roller mill scrap ring limit, the remaining minimum wall thickness of not less than 10mm.
  8. Parking, the first stop feeding, the host continues the mood, so that residual abrasive continued milling, about a minute, you can disable the host motor and motor analyzer, stop grinding work, and later stopped fan motor, the net in order to blow residual powder.
