Overview of MTM Trapezium Mill
MTM Medium Speed Trapezium Mill adopt numbers of national patents, such as trapezium working surface, flexible connection, roll linked pressure boosts etc. The grinder mills have completely overcome defects of traditional mills in amplification fields、capacity、fineness、energy consumption and service life etc.
The application of MTM Trapezium Mill
MTM Medium Speed Trapezium Mill are mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. The grinder mills 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 of the trapezium mill is between30—400mesh. Fully considered the needs of desulfurization, MTM Medium Speed Trapezium grinder mills could perfectly work with desulfurization equipments to increase the efficiency of desulfurization. So the grinder mills are the best choice of desulfurization.
Features & Benefits of MTM Trapezium Mill
1. The trapezium shaped roller and ring of the grinder mills 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 grinder mills works.
3. The powder classifier adopts high density impeller which can increase powder precision and capacity of the trapezium mill.
4. The grinder mills have adopted high-efficiency and energy-saving blower.
5. Using convenient impeller adjusting device.
Working principle of MTM Trapezium Mill
The main unit of the trapezium mill runs with a central shaft driven by a transmission device. The top of the trapezium mills’shaft is connected with a quincunx stand, on which a grinder roller is installed to form a swing support. The grinder roller of the trapezium mill not only rotates around its own axis, but also rotates around the grinder ring and rotates itself due to the friction. There is a spade system under the quincunx stand at the bottom end of the grinder roller. During rotation of the spade and the rollers of the trapezium mill, 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.
