MTM Medium Speed Trapezium Mill
MTM Medium Speed Trapezium Mill adopts numbers of national patents, such as trapezium working surface, flexible connection, roll linked pressure boosts etc. It has completely overcome defects of traditional mill in amplification fields、capacity、fineness、energy consumption and service life etc.
MTM Medium Speed Trapezium Mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. It can produce powder from non-flammable and non-explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum etc. The final size is between30—400mesh. Fully considered the needs of desulfurization, MTM Medium Speed Trapezium Mill could perfectly work with desulfurization equipments to increase the efficiency of desulfurization. So it is the best choice of desulfurization.
Application
MTM Medium Speed Trapezium Grinding Mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining, etc. The MTM Medium Speed Trapezium Grinding Mill can produce powder from non-flammable and non-explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum etc. The final sizeof the powder is between30—400mesh. Fully considered the needs of desulfurization, MTM Medium Speed Trapezium Grinding Mill could perfectly work with desulfurization equipments to increase the efficiency of desulfurization. So it is the best choice of desulfurization.
Features and Benefits
1. The trapezium shaped roller and ring highly improved the crushing efficiency.
2. The pressure springs work the function of balance and pressurize. Elastic connection can reduce vibration and keep balance when the equipment works.
3. The powder classifier adopts high density impeller which can increase powder precision and capacity.
4. Adopting high-efficiency and energy-saving blower.
5. Using convenient impeller adjusting device.
Working Principle
The main unit runs with a central shaft driven by a transmission device. The top of the shaft is connected with a quincunx stand, on which a grinding roller is installed to form a swing support. The grinding roller not only rotates around its own axis, but also rotates around the grinding ring and rotates itself due to the friction. There is a spade system under the quincunx stand at the bottom end of the grinding roller. During rotation of the spade and the rollers, materials will be fed into the space between rollers and ring to form a material layer. The materials will be grinded due to centrifugal force.
