Overview Of MTW European Trapezium Mill↑

MTW SERIES EUROPEAN TECHNOLOGY TRAPEZIUM MILL--the latest grinding equipment, with its own knowledge patents, have reached modern advanced level in the world. This series mill absorbing the European advanced technology and many engineers’ ripe experience, combining the actual requirement and proposal of our 9518 customers’, have been developed on the basis of our professional engineers’ hard researching. This new type mill adopts bevel gear overall drive, inner automatic Thin-Oil lubricating system, arc air channel and several latest patent technology.

The Application Of MTW European Trapezium Mill↑

MTW European Trapezium Grinding Mill is mainly applied to the powder processing of mineral products in the industries of metallurgy, construction materials, chemical, and mining, etc. This Grinding Mill can produce powder from various non-flammable and non-explosive mineral materials with Moh’s hardness below 9.3 and humidity below 6%, such as quartz, feldspar, calcite, talcum, barite, fluoride, Xircom, cinder, white lime, cement clinker, activated carbon, dolomite, granite, soft coal, coking coal, lignite, magnesia, chromium oxide green, gold ore, red clay, clay, kaolin, coke, coal Gangue, porcelain clay, kyanite, fluorspar, bentonite, medicinal stone liparite, diabase, pyrophyllite, shale red stone, emeraldite, basalt, gypsum, graphite, carborundun, heat insulating material, etc.

The Features & Benefit Of MTW European Trapezium Mill↑

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

Main Parts Of MTW European Trapezium Mill↑

This grinding mill equipment is mainly composed of host machine, redactor, separator, fan, cloth dust controller, piping device, integrated device, and electric engine etc. The whole set of equipment is composed of jaw crusher, belt bucket-elevator, feeder machine, storage silo, electrical control tank etc.

Working Principle Of MTW European Trapezium Mill↑

The main shaft of MTW European Trapezium Grinding Mill connected with the the roller hanger in the top.It is drived by the bevel gear which trabsmits in a whole.The rollers of the Grinding Mill rotate not just around the main shaft, but also around the grinding ring.Also,rollers can rotate to itself because of friction.Shovels are installed at the bottom end of hanger; materials will be fed into space between rollers and ring to form a material layer when shovels rotate together with rollers. Then The classifier drives the blades in the rotary table through the speed motor to classify the powder.
