MTM Trapezium Mill

MTM Series Medium Speed Trapezium Mill

MTM Series Medium Speed Trapezium Mill adopts the trapezoidal shape of working face, the flexible connection, the grinding roller mill supercharger and a number of national patent technology, completely overcomes the defects of the traditional industrial milling machine in the scope of application, yield, fineness, energy consumption and long service life, is the most ideal substitute of Raymond mill, high pressure suspension roller mill, ball mill the traditional milling machine. At present, the models have been widely used in China's metallurgical, power, chemical industry, iron and steel, building materials, coal and other industries, has had the huge economic efficiency.

MTM Series Medium Speed Trapezium Mill application

MTM Series Medium Speed Trapezium Mill Mainly used in building material, chemical industry, metallurgy, mining, abrasives, refractories, ceramics, steel, thermal power and coal industry grinding Mohs hardness below level 9, humidity below 6% in various non flammable and explosive mineral material, finished product fineness can be adjusted in 30 ~ 400 mesh of arbitrary order. For example, the cement (born clinker), quartz, feldspar, calcite, gypsum, limestone, dolomite, graphite, fluorite, wollastonite, rock phosphate, calcium magnesium phosphate fertilizer, urea, electrolytic manganese metal, alloy, Meng Tie coal, coal gangue, slag, zircon sand, talc, granite, potash feldspar, marble, barite, ceramic, glass and other more than 1000 kinds of material grinding machining.

MTM Series Medium Speed Trapezium Mill Working principle

The bulk materials by jaw crusher to the desired size, by the elevator will be the materials to the storage hopper, then through the electromagnetic vibrating feeder will even materials quantitatively and continuously into the indoor host grinding grinding. After grinding the material was fan airflow into the powder selecting machine are graded, in select powder machine impeller role, does not meet the requirements of grinding fineness material into indoor re grinding fineness, comply with the requirements of material with gas flowing through the pipeline into the cyclone powder collector, were isolated and collected, the discharging device is discharged for the finished product powder. After the flow separation by cyclone powder collector upper return air duct into the fan. This system belongs to the closed circulation system, and the positive and negative pressure condition.

Because the grinding room were grinding material contains a certain amount of moisture, grinding heat generation causes gas evaporation grinding indoor expansion and change the gas flow system, and the inlet and the pipe joint sealing problem, enter the outside air makes the system within the gas loss to balance, therefore, by setting the the air outlet of the blower and the exhaust pipe valve excess gas into the bag filter, and the discharged after purification, the regulating system flow balance while achieving environmental production.
