used trapezium mtw mill introduction
used mtw Trapezium Mill
mtw series trapezium mill is the latest Grinding Mill, which is developed by our company’s experts based on 10 years’ r&d on grinding machine. it owns many independent patents property, such as overall prick gear drive, internal thin oil lubrication system, arc-shaped air duct. all of these make it leading the trend of the milling industry in the world. according to the experience and suggestions from 9518 customers, zenith has made great efforts to bring mtw european trapezium grinding mill into the world.
this new industrial mill takes the most advanced patent technology from european, and the supply the customers with outstanding performance at low costs.
the european type grinding mill is ideal for grinding barite, lizenithne, 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.

used trapezium mtw mill working principle
mtw series of european working process of milling machine at a whole through the bevel gear driven center gear shaft rotation, shaft coupling with the upper roller hanger, rack with roller device and the formation of swing pivot. not only roller device rotating around the central axis, but also the revolution around the grinding ring, roller itself is a result of friction and rotation. under the hanger with roller blade, roller at the bottom of its location, roller blade and turn the course of the same toss of materials between the feed roller grinding ring, the formation of litter layer, the material layer by roller outward rotation of the centrifugal force (ie, extrusion pressure) the material is crushed, thus achieve the purpose flour.
used trapezium mtw mill structure & features
used mtw trapezium mill
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 whole series of milling machines for the vertical structure, small footprint, complete and strong, and the host transmission with sealed gear box, transmission stable. an important component of the mill are made of high quality steel, so wear a reliable machine, milling machine electrical centralized control, a reasonable selection of advanced high degree of automation. feeder small, light weight, easy to adjust and maintain and very power.
1. overall bevel gear drive, energy loss, high efficiency;
2. internal thin oil lubrication system, advanced and reliable;
3. curved duct, air flow loss, and good material flow;
4. roller and grinding ring of special design, cutting edge blade surface can be changed, so that grinding efficiency, the use of cost reduction;
5. the product size is adjustable and controllable high efficiency separator;
6. without resistance into the wind spiral (small observation door without vortex);
7. humanized design, easy to operate.

used trapezium mtw mill projects
black thunder thermal coal mine
the black thunder thermal coal mine is located in the southern powder river basin of wyoming produce coal. after passing through a vibrating grizzly screen, jaw crusher, heavy duty sizing screens and a large scale Cone Crusher, the coal is reduced to 0-15mm in diameter.
in the grinding mill plant, the mtw trapezium grinding mill in european type will be grind the crushed coal in fine powder, the size can be down to 0.04mm (or 400 mesh).
this project in usa supply most of the thermal coal, and the grinding mill used in the plant can increase efficiency rapidly.
