How MTW series trapezium mill works?

MTW series trapezium mill adopts several latest patent technology such as bevel gear overall drive, inner automatic Thin-Oil lubricating system, arc air channel etc.

MTW series European Technology Trapezium Mill is widely applied in mining, metallurgy, construction, chemical industry etc. They can process materials which are non-flammable, non-explosive, with Moh’s hardness below 9 and moisture below 6%, such as limestone, quartz, chrome oxide, calcite, bauxite, manganese, iron ore, barite, fluorite, marble, copper ore, phosphorite, slag, dolomite, granite, fertilizer, compound fertilizer, coal ash, soft coal, basalt, gypsum etc.

Working principle of MTW series trapezium mill:
The bevel gear drives the main shaft, which is connected to the roller hanger on the top. There are grinding rollers installed in the hangers and forming a swing support. The rollers rotate not just around the main shaft, but also around the grinding ring. Besides, rollers can rotate itself as well because of the friction. .A set of shovel are installed at the lower end of the quincunx-rack. While turning together with the rollers ,the shovels shed the stuff onto the gap between the rollers and the ring, and that’s where the stuff layer forms. The rotating rollers ,while turning together with the ring ,grind the stuff layer into powder. The classifier drives the blades in the rotary table through the speed motor to classify the powder. The turning speed of the impeller can be adjusted to the requirement of the fineness of powder products
