Feature
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 Grinding 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 Grinding 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 Grinding 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 Grinding 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 Grinding 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;
