MTM Trapezium Mill

Structure Analysis

  • millstone: including the guide ring, ring, ring, the wind stopper lining plate, plate, scraping plate and a lifting device etc.
  • grinding roll: roll sleeve is easy to wear pieces, claims to have enough toughness and good wear resistance.
  • powder selecting machine:it can be divided into static, dynamic and efficient combined type powder selecting machine three major categories.

Product Application

MTM trapezium mill is widely used in electric power industry, metallurgy industry, chemical industry, building construction, coal industry, fireproofing materials making industry and some others. About the application of material,it can apply to various non-flammable and non-explosive materials which Mohs hardness ≤9 and humidity content ≤6%. For example, cement, quartz, feldspar, calcite, gypsum, limestone, dolomite, mica, bentonite,graphite, fluorite, rock phosphate, coal, slag, talc, granite, marble, barite, ceramics, glass and other material. Its output product fineness is among 30~ 400meshes and it is adjustable.

Product Advantage

  • Low production cost, high performance

    The design of the grinding roller and grinding ring into strips, reduced access to material between grinding roller and grinding ring decline, thereby extending the material roller compaction time, increased crushing effects.
  • Good stability, high reliability

    It is equipped with can improve the precision of powder density separator impeller, speed with no change, increase blade density improves the fineness of finished products, finished products under the same power 50% more.
  • Product size composition well

    Within tilt duct can ensure the video into the inlet volute smooth down the incline of the material fell into the mill.Using convenient impeller adjusting device allows separators of leaves end of shell gap size can easily adjust.

Operational Principle

MTM trapezium mill operational principle is easy to understand. Air is driven into the undersurface of the grinding ring and flows upward, carrying fines to the classifying section in the grinding mill. The classifier allowed the pulverized material to pass and the oversized particles are drove back to the grinding chamber for further processing. The whole mill operates under negative pressure conditions, which can maximize the service life of span>major mechanica components. Thus minimizing mill maintenance and plant housekeeping problems have been solved.
