Description Of MTW Series Trapezium Mill

MTW series trapezium mill can be used to process limestone, calcite, marble, talcum, barite, gypsum, lime, coarse whiting, attapulgite, dolomite, coal, feldspar, quartz, graphite, coal gangue, fluorite, slag, cement clinker, bauxite, kaolin, cement, activated carbon, petroleum coke, coal ash, iron oxide red etc. ZENITH MTW series trapezium mill is the lastest grinding mill, which absorbs the European advanced technology and many engineers’ ripe experience.

Features

  • 1.Bevel gear overall drive: traditional grinding mill is driven by speed reducer and coupling. It is hard to be installed. And there will be too much noise, and the efficiency is lower. MTW series mill is driven by bevel gear, so its structure is compacter, more efficient and easier to be installed;
  • 2.Inner automatic Thin-Oil lubricating system: the traditional mill adopts grease lubrication, so the lubricating resistance is stronger, the temperature will become high soon, the service life of the bearing is shorter. MTW series mill adopts inner L.O.pumps, so the main shaft bearing and bevel gear can be lubricated without additional lubrication system with good stability and reliability;
  • 3.Arc air channel: all air channel of traditional grinding mill is upright board type. In this case, there will be stronger resistance when the air impacts the air channel board, and the energy of collisions of air molecules loss heavily, as a result, the air channel will be jammed easily because of the eddy air flow. MTW series mill adopts a cambered air channel, the tangential air goes into air channel easily because there is little resistance. And the inner outlet is very good for the grinded material to spread around and avoid grinding material being jammed;
  • 4.Cambered shovel with renewable edge: The traditional shove is integral and the edge is always worn out quickly, so you have to replace it in short time, which affects the working time and wastes too much steel. The shovel edge of MTW series mill adopts high wearable limit alloy, its life will be longer. You only want to change the edge, not the whole shovel. so the steel material is saved. In addition, because the traditional shovel is plane type, the grinded material stacks on the same plane when it is scooped up. So the middle parts of the roller is worn out heavily. But the cambered shovel can scoop up the grinded material in the same vertical plane, which makes the rollers and ring worn equally. At the same, the grinding efficiency is higher and capacity is higher with good product particle size;
  • 5.No resistance snail shell (small checking door so that there is not an eddy air flow): In the traditional grinding mill, the checking door of snail shell is prominent, which means the checking door and snail shell are not on the same plane. So there will be eddy air flow easily come into being. As a result, the energy waste is bigger. MTW series mill make the inner surface of checking door stay with the inner surface of snail shell on the same plane, so the eddy air flow is avoided efficiently;

MTW Trapezium Mill is the best equipment

Fine calcium powder market to rise rapidly, with the industrial development of modern building materials and powder used in all aspects of the paper, putty powder, daily chemicals, feed additives, pharmaceuticals, building materials.Fine calcium powder in the process of production of calcium carbonate ore full crushing mill, and then by chemical means to generate high purity precipitated calcium carbonate, that is fine calcium powder.The fine calcium powder production process has high requirements on the purity of calcium carbonate, calcium carbonate mill grinding intensity of the more stringent requirements, in general, is difficult to achieve high-quality fine calcium powder products.Conventional light calcium powder mill technology has seriously affected the production and application of fine calcium powder, iron pollution is the fatal flaw of the calcium carbonate mill processing.

MTW Series Trapezium Mill

In order to solve the problem of calcium carbonate mill in the use of fine calcium powder market, ZENITH Heavy Industry Science and Technology R & D engineers designed MTW Trapezium Grinding Mill, learn from the successful experience of Europe in light calcium powder mill, mill on the original calcium carbonatethe overall improvement of the European version of the material of the mill has been substantial improvements in the processing of fine calcium powder production process play an irreplaceable role.

Brand new , redesign the structure of the internal grinding, the premise of ensuring energy saving and environmental protection, reduce the actual contact with the material to ensure that the materials of great purity, used as a light powder mill, and other quartz stone millmachine with absolute advantage.
