MTW European Trapezium Grinding Mill

obtain international advanced technology as well as many proprietary intellectual property rights. Our experts design MTW series grinding mill according to advices of customers of YGM9518 mill and their long-term experiences. The MTW series

grinding mills

adopt bevel gear integral transmission, inner light-oil lubrication system, arc whirl tube and another proprietary technology.

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. They can produce powder from various non-flammable and non-explosive mineral materials with Mohs 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.

• bevel gear integral transmission: The traditional grinding mill needs decelerator and ratcheting to drive the main shaft that increase the centering difficulty and is easy to bring noise as well as reduce the efficiency. MTW series grinding mills adopt bevel gear integral transmission that compact the whole structure and simplify the installation as well as improve the efficiency.
• Inner light-oil lubrication system: The traditional grinding mills’ lubrication adopts grease lubrication which increases the resistance of lubrication, creates high inherent temperature and shortens the service life of bearing. MTW series grinding mill adopts light-oil lubrication achieve the lubrication of bearing without oil pump and lubrication station.
• Arc whirl tube: The traditional grinding mills adopt board-type whirl tube that increases the resistance, reduces the performance, and stops the air flow and so on. MTW series grinding mills adopt arc whirl tube reduce the resistance and avoid the air-stop and so on.
