MTW European Trapezium Mill is the newest grinding equipment which enjoys many patented technology and reaches the international advanced level. It is the up-to-date grinding equipment designed by our devoted research team, basing on feedbacks and advice from 9518 mill customers and rich experience on mill research. The mill enjoys several patent technologies, such as bevel gear overall drive, inner automatic Thin-Oil lubricating system, arc air channel, etc.

Features:

1) Bevel gear overall drive: the traditional grinding mill is driven by speed reducer and coupling. It is hard to be installed. And there will be too much noisy, and the efficiency is lower. MTW series mill is driven by bevel gear, so its structure is compacter, easy to be installed and more efficient.

2) Inner automatic Thin-Oil lubricating system: the traditional mill adopts grease lubrication, so the lubricating resistance is stronger, the temperature will be higher soon, the bearing life is shorter. MTW series mill adopts inner L.O. pumps, so the main shaft bearing and bevel gear can be lubricated without an additional lubrication system.

3) Arc air channel: all of the 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 small resistance. And the inner outlet is very good for the grinded material to spread around and avoid grinding material jammed.

4) Cambered shovel with renewable edge: The traditional shove is integral and edge always be worn out quickly, so you have to renew 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, that makes the rollers and ring worn equally. At the same, the grinding efficiency is higher and capacity is higher;

5) Separated cyclone: There is a separated structure between inner piping and mixed air and powder. The efficiency and precision of classifying is promoted highly;

6) 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, that mean 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;

7) Perfect outward appearance: Both of the inner parts and outer part of the MTW series mill adopt advanced structure and beautiful arc structure design. This makes the mill advanced and beautiful.

1.MTW European Trapezium Mill can be used in grinding basalt

Basalt is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey. Ground basalt is used as railroad ballast, asphalt, and road aggregate for highway construction. MTW series trapezium mill is an important equipment to grind basalt in road construction.

2. MTW European Trapezium Mill can be used in Kaolinite grinding

Kaolinite, a clay composed of kaolin, is used in ceramics, medicine, coated paper, as a food additive, in toothpaste, as a light diffusing material in white incandescent light bulbs, and in cosmetics. It is generally the main component in porcelain. The largest use is in the production of paper, including ensuring the gloss on some grades of paper. MTW series trapezium mill can be used to grind Kaolinite into fine powder in the production of paper.

3. MTW series trapezium mill is used for processing talc powder

Talc Powder, also called French Chalk, is the grinding products of Talc stone. It is formed by Calcium Chloride Flakes, widely used in paper making and cosmetics Industry. Talc is a hydrothermal alteration mineral. Magnesium-rich minerals often become talc by hydrothermal alteration, so it is often called olivine talc, enstatite, hornblende, tremolite, etc. MTW series trapezium mill is an important equipment in Talc grinding.
