Introduction
MTW series mills obtain international advanced technology as well as many proprietary intellectual property rights. Our experts design MTW series mill according to advices of customers of YGM9518 mill and their long-term experiences. The MTW series mills adopt bevel gear integral transmission, inner light-oil lubrication system, arc whirl tube and another proprietary technology.
Application:
This series mills are 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.

Working principles of the MTW Series Trapezium Mill:
Firstly, raw material should be crushed by the jaw crusher to the size specified, and then the crushed stuff is elevated into a hopper from which the stuff is loaded, through the vibrating feeder, evenly and continuously into the grinding chamber for power-processing. After this, the ground stuff is carried by the air from the blower into the Classifier for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.
The grinder is driven by rotation of the central axle through decelerator, with the up end of the axle connecting to a quincunx-rack upon which the grinding equipment is fixed.
The whole set equipment turns together with the axle along the grinding ring while the rollers rotate driven by the fractional force. A set of shovel are installed at the lower end of the quincunx-rack, and positioned at the piece under the lower-end of the rollers. While turning together with the rollers, the shovels shed the stuff onto the gap between the rollers and the ring and the stuff layer is formed there. The rotating rollers, while turning together with the ring, grind the stuff layer into power.
To separate the ground stuff into the fine power-product and the rough stuff is done through vane on the turntable driven by a speed adjustable motor. The turning speed of the vane can be adjusted to the requirement of the fineness of powder products. If more finer powders are needed, the turning speed will be increased so that the rough stuff can be thrown towards the outer wall of the pipeline away from the air current and then back into grinding chamber for redone. Whereas, the powder fine enough will be collected as the final product by the cyclone-collector.
It plays an important role in ensuring the smooth functioning of the grinder. As the highly spinning air current mixed with ground stuff is flown into the cyclone-collector, the ground stuff is separated from the air-current.
