MTM Trapezium Grinder

Since the early 1980s SBM has been designing and manufacturing high-performance grinding mills under the SBM brand.MTM trapezium grinder is a kind of leading-world-level industrial milling machinery.Basing on industrial mill research of many years and adopting world-leading-powder processing technology,SBM MTM trapezium grinder become a popular mill product.
Now many customers are fond of it for its incomparable features. SBM MTM trapezium grinder are reliable, high-performance, low-maintenance demolition tools that give a low cost per ton of material processed. Moreover, the pressure springs have balancing and pressurized function. The elastic connections reduce vibration, keep balance, and avoide resonance.

Application of MTM Trapezium Grinder

SBM MTM trapezium grinder 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 MTM trapezium grinder is widely used in electric power industry, metallurgy industry, chemical industry, building construction, coal industry, fireproofing materials making industry and some others.

Distinctive feature of MTM Trapezium Grinder

  1. High density and precision impeller device.
  2. Efficient balance compression spring,which can guarantee the stable pressure, reduce the vibration and noise.
  3. Unique spring connection,avoiding the wastage of main shaft and bearing by the material.
  4. Stable output and fineness.When the grinding roller and ring is wear and tear,we can keep them a constant distance by adjusting the spring.
  5. Host and classifier using damping spring both vibration and noise reduction and avoid the body crack causing by sympathetic vibration.
  6. Quick adjustment of maintenance.High pressure spring length can control the distance between the grinding roller and grinding ring.
  7. Equipped with high density classifier impeller,improve the fineness of finished product.

Working principle of MTM Trapezium Grinder

Inside the MTM Trapezium Grinder,air is driven into the undersurface of the grinding ring.The air entering the MTM Trapezium Grinder 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 Trapezium Grinder operates under negative pressure conditions.Thus minimizing mill maintenance and plant housekeeping problems have been solved.
