mtw trapezium grinding mill main features and benefits
mtw trapezium mill
1. the bevel gear transmits in a whole, which makes the grinding mill machine’s structure more compact, installation and commission more convenient.
2. the internal oil pump of the grinding mill machine can lubricate the bearings both in main shaft and bevel gear shaft, without connecting any external oil pump or lubrication station.
3. former straight wind tunnel in the traditional grinding mill machine is replaced by curved one.
4. sheet of the shovel is easy for change, and cyclone collector in isolated type.
5. porthole adopts smooth wind spiral, which also gives the grinding mill machine a very beautiful appearance.
mtw trapezium grinding mill working principle
the european type grinding mill is ideal for grinding barite, lisbmne, mica, talcum, quartz, calcite, granite, porcelain clay, basalt, gypsum, gold, iron ore, bauxite, copper, cement, coal etc. the fineness can reach 38micron (400mesh). this new type trapezium mill adopts bevel gear overall drive, trapeziums working surface, inner automatic thin-oil lubricating system, arc air channel and several latest patent technology, which is designed to substitute for ball mill, raymond mill, vertical mill etc.
the powder grinding plant with trapezium mill consists of jaw crusher, electro-magnetic vibrating feeder, main unit, deceleration machine, blower, dustpan elevator, impulse dust cleaner, piping device, cyclone collector device, classifier, high-pressure motor and muffler and so on.
the bevel gear transmits in a whole and drives the main shaft, who is connected with the roller hanger in 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 to itself as well because of friction. shovels are installed at the bottom end of hanger, when shovels rotate together with rollers, materials will be fed into space between rollers and ring to form a material layer, which will be grinded due to centrifugal force. the classifier drives the blades in the rotary table through the speed motor to classify the powder.
