Trapezium Mill

Large capacity, low consumption, environmentally friendly

Trapezium Mill

Got CE and National Patent Certificate, Trapezium Grinding Mill got good reputation with our customers from Australia, US, UK, Spanish and other countries. Trapezium Mill adopts our patented technologies, which are trapezium working surface, flexible connection, roller linked pressure boost, etc. It has reached the advanced international level of powder making equipment manufacturing. 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, Vibrating Feeder, Main Frame, Blower, Powder Concentrator, Powder Collecting System, Piping Device, and Bag Deduster.

Output size : 1.6~0.045 mm,fineness can reach to 0.038mm

Production capacity : Up to 22TPH, capacity depends on the size of fineness

non-flammable and non-explosive minerals with Moh’s hardness lower than 9 and humidity less than 6%

The mainframe is driven by the speed reducer through the central axis in the mill. The quincunx stand connected with the upper part of central axis, at the quincunx stand and rollers there is shovel system. Materials are fed into the space between rollers and shovels when they are turning, and then be grinded by the pressure produced when rollers are turning, thus powder is made. 


metallurgy,building materials,chemical and mining

TGM super pressure trapezium mill mainly includes main frame, speed reducer, separator, blower, bag filter covered by square box, connecting pipes, cyclone collector, and motor etc. The complete set of TGM super pressure trapezium mill is composed of jaw crusher, bucket elevator, electromagnetic grizzly feeder, and electric panel. TGM Series Super Pressure Trapezium Mill can grind all kinds of non-flammable and non-explosive minerals with Mohs’ hardness less than 9 and humidity less than 10%, and TGM Series Super Pressure Trapezium Mill is widely used in metallurgy, manufacture of building materials, chemical industry, mining industry, etc.


Compared with the traditional grinding mill,the Super Pressure Trapezium Grinding Mill has below advantages:
1. The trapezium roller and grinding ring improve the grinding efficiency greatly. The roller and grinding ring are designed in inverted trapezium with different diameter,which reduce the slip velocity of materials between roller and grinding ring,extend grinding time,and improve the grinding efficiency;
2. With high efficient balanced adding pressure springs.Adopting the advantages of Raymond Mill and High Pressure Suspension Mill,Super Pressure Trapezium Grinder has longer service life. The roller assembly has been linked by the pulling pole and the levelled springs, with the radial force yeilding, which avoids the bulk material entering into the grinding chamber to wear down the principal axis and the the bearings, thus the service life will be longer;
3. Using flexible connection to connect main frame and powder concentrator,so the damping spring and airproof belt can reduce the vibration and noise,and avoid the resonance as well;
4. There is high desity and high precision impeller;
5. There is high-efficiency and energy-saving centrifugal induced draft fan;
6. With the impeller adjusting device brings more convenience. The clearance between housing and powder concentrator’s blade front end also effects the fineness of the final product.The patent technology enables adjust the clearance more convenience.
7.Innovative roller, grinding ring and blade designs.
8.Roller linkage supercharger.
9.Flexible connection.
10.Efficient and practical, product fineness can be adjusted.
11.Energy efficient centrifugal fan.
12.The gap adjustment of the end of the separator and shell is more convenient and faster, which improved the efficiency of the powder collection.
