MTM medium speed trapezium mill

Based on years’ research experience ,we expert have developed this new kind of MTM Medium Speed Trapezium Mill .And the MTM Medium Speed Trapezium Mill adopt trapezoid working surface ,flexible connection ,consecutive movement and pressure boost of the grinding roller ,and other multi -national grinding mill’s licensed technologies .And compared with the traditional vertical mill, the MTM Medium Speed Trapezium Mill features small covering area, low energy consumption, long service life ,low cost of the wearing parts and high cost performance .And at present ,the MTM Medium Speed Trapezium Mill have found their extensive application in the field of metallurgy, electric power, chemicals, iron and steel, building materials, coal and so on, which have created huge economic benefits.

Technical features of MTM medium speed trapezium mill

This kind of MTM Medium Speed Trapezium Mill have designed the grinding roller and ring to the ladder-type, which have reduced the downturn speed of the materials between the grinding roller and ring, which can also extend the speed and improve the crushing effect.

This kind of MTM Medium Speed Trapezium Mill has taken the flexible connection which can relief and balance the shaking effect. And the powder classifier will be connected with the main unit by several decoupling spring and be sealed by the flexible belt, which have reduced the vibrating and noise and avoided the resonance.

Equipped with the powder classifier impeller ,the MTM Medium Speed Trapezium Mill have improved the powder classifying precision and high production density .And with the same rotating speed ,the improvement of the impeller’s density can improve the fineness of the products ,which can improve the production by over half times with the same dynamic force.

Equipped with high-efficient and energy-saving eccentric induced draft fan .the efficiency of energy-saving eccentric induced draft fan can reach by over 85%,while the traditional grinder ‘s straight blade can just reach 62%.

Equipped with the impeller adjustment is convenient and the space size between the end of the classifier’s impeller and shell will also influence the fineness of the final products. And this kind of impeller equipment will make the space adjustment become more convenient.

Main structures of MTM medium speed trapezium mill

The standard configuration of MTM Medium Speed Trapezium grinder consists of main unit , powder classifier , cyclone collector, decelerator ,dust catcher ,blower, motor, pipes, feeder, and control cabinet.

Working principle of MTM medium speed trapezium mill

The working functions of the MTM Medium Speed Trapezium Mill are as follows: The main unit runs with a central shaft driven by a reducer device. The top of the shaft is connected with a quincunx stand, on which a grinding roller is installed to form a awing 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 spade system under the quincunx stand, which is 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.
