MTW Milling Machine

According to collected the feedback from customers’ long-term experiences,SBM designed the MTW milling machine.It is a upgrade grinding mill of MTM trapezium grinder.This new generation milling machine adopts bevel gear overall drive, trapeziums working surface, inner automatic thin-oil lubricating system, arc air channel and several latest patent technology, which is designed to substitute for ball mill, Raymond mill, vertical mill etc.
The final product’s fineness of MTW milling machine can reach 38micron (400mesh).To facilitate the use of MTW milling machine,we equipped it with trapezium mill consists of jaw crusher, electro-magnetic vibrating feeder, main unit, deceleration machine, blower, dustpan elevator, impulse dust cleaner, piping device, cyclone collector device, classifier, high-pressure motor and muffler and so on.

Application of MTW Milling Machine

SBM MTW milling machine are designed to grinding the stones whose Moh's hardness below 9.3 and moisture below 6% of all kinds of inflammable and explosive mineral materials processing such as limestone, calcite, dolomite, barite, gypsum, talc, calcium carbonate,bentonite and so on.Its final product size is 1.6 mm to 0.038 mm,which is very fine.

SBM MTW milling machine is the ideal prowder making equipment in electric power industry, metallurgy industry, chemical industry, building construction, coal industry, fireproofing materials making industry and some others.

Distinctive feature of MTW Milling Machine

  1. The shovel is made of high manganese steel which is more durable and the blade can replace easily.
  2. Cone gear whole transmission-compact conformation, convenient installation, reducing dissipation of energy.
  3. Isolation type cyclone powder collector. Effectively improve the efficiency and precision of choosing powder.
  4. The observe door and air inlet volute is in the same surface,voiding the eddy current effect and reducing energy consumption.
  5. Optimization design for grinding roller grinding ring of main-spring pressurization, high-wearing feature.
  6. Internal thin oil lubrication system. Advanced and reliable, prolong service life.
  7. Curved duct. Loss of the air volume is small, the liquidity of material is good and not easy plugging material.

Working principle of MTW Milling Machine

The entire air system of MTW Milling Machine is a closed loop and is circulating under negative pressure condition.Big block material after broken to required size by the jaw crusher,will be sent to the storage hopper by the elevator.The material will be uniform quantitative continuously feed into the indoor host grinding of grinding by the vibrating feeder.The powder have been ginded being taken away by fan.By the classification of the classifier,the powder which meet the fineness requirements will be collected by the separation collection via the pipeline into the whirlwind set powder.then through the powder tube eduction is the finished product powder.
