MTW of European Strength Grinding Mill is our company design and long-term production grinding mill with stable, high efficiency, energy-saving, and environmental protection, which has excellent performance parameters and combines many domestic and foreign customer’s using experiences. It is widely used in mining, building materials, electric power, road and bridge, coal, metallurgy, chemical industry, ceramics, refractories and other industries. It can grind limestone, calcite, talc, barite, quartz, feldspar, iron ore, kaolin, bentonite, fly ash, bottom slag, pulverized coal, petroleum coke and other non-flammable and explosive mineral materials with a hardness of less than 9.3 and a humidity of less than 6%.
The MTW European Type Strength Grinding Mill adopts the heavy type design, which fully considers the grinding efficiency and service life, and has achieved many key breakthrough.The hanger device is upgraded to cone structure, the durability is greatly enhanced, the wind resistance is reduced, the grinding roller assembly adopts the floating sealing patent structure to effectively prevent the dust from entering, which is more than three times longer than the traditional structure.The wearing parts are made of highly wear-resistant materials, which prolong the service life, reduce the cost of replacement parts and equipment downtime.
Supply coarse powder device, blade type and cage type, three types classifier structures, meet different customer’s request for market. Make the fineness and the capacity reach to the best connection.According to the actual needs of users, can adopt blade type classifier or cage type classifier, using the frequency converter to adjust speed to achieve the fineness of the final powder which is adjustable between 80-600 mesh. Blade type classifier with low energy consumption, suitable for 200(200 mesh≈D90) or below.
Adopting high pressure blower, high efficiently adjusts the airflow; the arc wind duct design and non-resistance winds inlet snail shell design, reducing the resistance of airflow, so that making the material smooth flow.No dust leakage of equipment operation,the remaining air is collected by pulse bag dust filter, quick and automatic ash removal, with high dust removal efficiency, ensure the workshops are dust free operation.
According to the actual needs of users, it can be an open circuit system that allows the system to run the mill at full negative pressure to ensure long term continuous operation of the device at a constant temperature, which is safe, reliable, and energy efficient.
It adopts the new gear transmission, which is reliable and stable in operation and convenient to use and maintain.MTW138 and MTW178 adopt split arc gear integrated transmission, reduce the transmission chain, improve the transmission efficiency; adopt thin oil lubrication, no need maintenance shortly, and reduce the maintenance time and cost.
The bulk materials are crushed to the required particle size by the crusher and sent to the storage hopper by the elevator. The materials are quantitatively and continuously sent to the main machine for grinding by the vibrating feeder. The milled powder rises with the air flow of the centrifugal fan and enters the powder concentrator for classification. The powder meeting the fineness standard flows through the pipeline and enters the cyclone powder collector for separation and collection, The finished powder is discharged through the discharge valve. The air flow enters the centrifugal induced draft fan from the return air pipe at the upper end of the cyclone powder collector. The whole air flow system is closed and circulates under positive and negative pressure. An exhaust pipe is added at the outlet of the centrifugal induced draft fan to discharge the excess gas into the dust collector for filtration, and then discharge the clean gas to realize environmental protection production.
