Trapezium Grinding Mill is mainly consists of main frame, speed reducer, powder concentrator, induced draught fan, dust collector, piping device, integrator, and motor, etc.The whole grinding mill line include Jaw Crusher, Bucket Elevator, Mill Deceleration Machine, Vibraing Feeder, Main Frame, Blower, Powder Concentrator, Powder Collecting System, Piping Device,and Bag Deduster.

Features

1.Adopt the new wear-resistant materials to improve crushing efficiency, and extend the using life of the roller and the ring. The roller and ring are designed in inverted trapezium, which reduce the material's slip velocity between rollers and ring, extend grinding time, and enhance crushing efficiency and fineness.
2.Increased the density of the classifier’s blades so that the production has been greatly increased compared with other machines with the same rotating speed and motor.
3.With good sealing performace, tha machine reduced the noise and vibration, enhanced the fineness of the products, and improved the working efficiency.

Working Principle

The operation principle of main unit of Trapezium mill is that main unit runs with the central shaft that is driven by a gear box. 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 the central axle and grinding ring but also rotates around its own axle due to the friction. There is a pallet knife system at bottem of quincunx stand. The pallet knife system is under the grinding roller. With co-rotation of pallet knife and grinding roller, pallet knife will lift the materials into the space between roller and ring to to form a material layer. The materials will be grinded due to the centrifugal force of roller and thus finally achieve the aim of making powder.
