MTW Series Trapezium Mill

Zenith MTW Series trapezium mill is the latest grinding mill, which is developed by our company’s experts based on years’ R&D on grinding machine. It owns many independent patents property, such as overall prick gear drive, internal thin oil lubrication system, and arc-shaped air duct. All of these make it leading the trend of the milling industry in the world.

MTW series trapezium mill adopt bevel gear integral transmission, inner light-oil lubrication system, arc whirl tube and another proprietary technology. And obtain international advanced technology as well as many proprietary intellectual property rights.

Trapezium Mill Advantages

  1. Frequency conversion system
  2. The classifier is used of frequency conversion system, which costs lower energy, is in better control of speed, and has high degree of automation.

  3. Adoption of bypass powder collector
  4. It has isolation room and can reduce the possibility for powder to escape. Compared with normal powder collector, this system loses less pressure, has higher efficiency and is especially good at collecting ultra-fine powder.

  5. The same resistance system of equipment layout
  6. Equipment layout plan has the same resistance, which avoids different output pressure of two powder collectors, improves the powder collector’s efficiency, reduces internal circulation and increases the output of the mill.

  7. A straight line of three discharge ports
  8. Two discharge ports of powder collector and one discharge port of dust collector is in a straight line. This is good for centralized collection, reduction of labor amount and packaging.

  9. Maintenance platform.
  10. Setting maintenance platform and the mill maintenance is more convenient and safer.

Trapezium Mill Benefits

  1. Lower investment for the maximum benefits
  2. More stable performance of the machine
  3. Large output
  4. Considerate after-sale service is provided for our clients

MTW series of the European version of ladder mill adopts the conical gear driven spindle overall transmission, curved blade, low resistance curved duct, several new patented technology. It is suitable for various non-flammable and non-explosive mineral materials, which Moh’s hardness is under 7 and humidity is below 6%.

Trapezium Mill Working Principle

Closed system: The bulk materials are crushed to the desired size by jaw crusher. Then the materials will be sent to the storage hopper by the elevator. After vibrating feeder, materials will be even quantitatively and continuously into the indoor host grinding. After grinding, the powder is away by fan airflow, the powder selecting machine will grade the powder. Accord with the fineness of fly will be into the large cyclone collector with the gas flow through the pipe to be isolated and collected, and then the powder will be discharged from the powder tube discharge. The airflow returns air duct fan from large cyclone collector inhalation top.

Open system:In the grinding chamber internal grinding material with certain water content, the grinding heat generated in grinding chamber gas vaporizing expansion changes the gas flow rate, and the various machine pipe joint seal is not strict, let the outside gas is inhaled, the circulating air volume increase, therefore to achieve balance through adjustment of air exhaust fan and host the pipe, and the excess gas into the bag filter, the residual gas into the powder collected, the residual gas is discharged after purification.
