MTW Series European Technology Trapezium Mill

The MTW series European technology trapezium mill is mainly applicable to grinding process of mineral materials in metallurgy, building material, chemical and mine industries, etc. It can process the non-flammable and non-explosive mineral materials of hardness less than 9 on Moh’s scale, and the humidity less than 6%, including quartz, feldspar, calcite, talcum, barites, fluorite, tombarthite, marble, ceramic, bauxite, manganese ore, iron ore, copper ore, phosphate ore, iron oxide red, zircon sand, mineral waste residue, water granulated slag, cement clinker, active carbon, dolomite, granite, granat, iron oxide yellow, chemical fertilizer, compound fertilizer, flyash, soft coal, coking coal, lignitous coal, magnesite, chromium oxide green, gold ore, red mud, clay, kaolin, coke, coal gangue, porcelain clay, kyanite, fluorspar, bentonite, medical stone, rhyolite, diabase, pyrophyllite, shale, red sandstone, stromatolite, basalt, gypsum, graphite, carborundum, thermal insulation material, etc..

New Performance Features:

1. Bevel gear integral transmission: The traditional mill needs an additional speed reducer and the main shaft is driven through a coupling. In addition, the alignment is hard to handle during installation, and noise will be generated and the efficiency is low. The MTV series European technology trapezium mill adopts the integral bevel gear integral driving, which makes the structure more compact, installation and adjustment more convenient and quicker , and the efficiency increased greatly.
2. Internal thin oil lubrication system: The traditional mill is generally lubricated with grease. In that case, the lubrication resistance is large, and the temperature rises high and the service life is short. The MTV series European technology trapezium mill adopts the internal oil pump, it is not necessary to add an additional oil pump or lubrication station to lubricate the bearing of the main shaft and the bevel gear shaft.
3. Arc air duct: The air duct of a traditional mill is of straight panel type. In such structure, resistance force may be generated when the air impacts the air duct panel. And the energy loss is large due to the crashing between airflow molecules, thus the air duct may be subject to jamming because of vortexes. The MTV series European technology trapezium mill adopts the curvesurface air duct, and the inlet for tangential airflow is smooth, so the resistance is very small. The internal outlet direction is good for scattering the material and blocking is avoided.
4.The curve-surface spading tool whose blade can be replaced. The blade of the traditional mill is easily worn. Its spading tool is integral, so the whole tool needs to be replaced when the blade is worn. In that case, the material is wasted and`the shut down time for replacement is long, while the blade of MTV series European technology trapezium mill is made of alloy material with high wear resistance, it has a long service life. You only need to replace the blade part when replacement is required. In addition, if you use the traditional straight surface spading tool, the material will be piled on one layer after it is spaded, this may result in bad wear of the middle part of the mill roller and grinding ring, while the curve-surface spading tool can make the material move to the vertical surface, in this case, the upper, middle and lower parts of the mill roller and grinding ring all can be used for grinding, so the wear is uniform. At the same time, the effective working area is enlarged, thus the output is improved as well.
5.Isolated cyclone power collector: An isolated structure is used between the internal cylinder and the mixed air and powder, so the powder classification efficiency and precision will be greatly improved.
6.Air-inlet volute shell with no resistance (no vortex available at the small observation door): The internal door panel of the observation door of the air-inlet volute shell for the tradition mill is protuberant outward, and it is not on the same plane with the air-inlet volute shell, in this case, eddy-current effect may occur and the energy consumption of the system will be increased. As for the MTV series European technology trapezium mill, the internal door panel and the inner surface of the air-inlet shell is on the same curve surface. Therefore, eddy-current effect can be avoided.
7.Exquisite appearance: The European technology trapezium mill adopts many advanced structures. Besides, its appearance is designed in beautiful arc shape, which makes the whole machine look pretty and smart.
