MTW Series Trapezium Mill

MTW Series Trapezium Mill

MTW series European version of the Trapezium Mill is my company to absorb the latest European expert grinding technology and ideas, research and development experience in the long-term mill on the basis of a comprehensive 9518 mill use of customer suggestions, after painstaking research of innovative design out the latest type of mill. Excellent aircraft production to meet customer demand for 200-33μm (80-425Mesh) fines.

Detailed introduction

  • 1. High production efficiency
    Yield: a unique curved blade type design, material can be oriented facade, so the roller mill ring, middle and lower can be grinding, uniform wear, while also increasing the effective work area and improve the yield. Good product quality: cage, leaf disc separator, dual configuration options, unique sealing device for gas, effectively prevent "run meal."
  • 2. Low running costs
    Downtime: Built-pump, no need to reprovision or lubricating oil pump station can achieve circulating lubrication spindle bearings and gear shaft. High utilization of materials: using split blade design, the replacement simply replace the shovel blade; blade section with high wear-resistant alloy, long service life, which greatly reduces the cost of production.
  • 3. Low energy consumption
    Reduce resistance: low resistance curved duct, tangential flow into the import smooth resistance, internal export orientation in favor of material scattered and difficult blocking material. High efficiency dust collection: powder collector binoculars isolated a unique structure, high dust collection efficiency, low cycle powder.
  • 4. Small footprint
    Compact: bevel gear integral transmission, more compact, more convenient installation adjustment. Beautiful appearance: the appearance with curved design, a beautiful simplicity, a grade.

Working principle

Large bulk materials through the jaw (hammer) crusher to the desired size, by the elevator to the hopper the material, and then by the electromagnetic vibrating feeder evenly host quantitative material continuously fed indoors grinding mill . After grinding the material is selected airflow blower powder machine grading, the role of classifier wheel, does not meet the requirements of the fineness of the material falling into the interior re-grinding mill, in line with the requirements of the fineness of the material with the flow through the pipeline inside into the cyclone powder collector, were separated and collected by the exhaust discharge device is finished powder. Airflow separated by cyclone powder collector tube into the upper end of the return air fan. The system is a closed loop system, and run under negative pressure condition.

Since the grinding mill interior being some of the water-containing material, the heat generated during the grinding mill chamber will cause evaporation gas expands changing air flow system, coupled with the feed port sealing problems at various pipe joining, outside ingress of air such that the air flow within the system out of balance, for which the fan through the outlet provided in the exhaust pipe valve the excess gas is introduced into the baghouse, and is discharged after purification, in the balance regulating system airflow while achieving environmental produce.
