Super Pressure Trapezium Grinding Mill

Got CE and National Patent Certificate, Super Pressure Trapezium Grinding Mill got good reputation with our customers from Australia, US, UK, Spanish and other countries.
Super Pressure Trapezium Mill adopts our patented technologies, which are trapezium working surface, flexible connection, roller linked pressure boost, etc. Super Pressure Trapezium Mill has reached the advanced international level of powder making equipment manufacturing.

Working Principle:

Large materials are crushed by Jaw crusher to the needed sizes firstly, then the materials are elevated to storage hopper by bucket elevator, third, the materials are fed into the grinding chamber for grinding by vibrating feeder equably and continuously. The powder after grinding goes upwards together with the airflow, after separating by powder separator, those which can meet the fineness requirement enters into the cyclone powder collector through pipe together with the airflow, and then discharged from the discharge valve as final products. The airflow is sucked into centrifugal blower through wind recycling pipe at the upper part of cyclone powder collector. 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, rollers are set and by which the vibrating pivot formed. Below 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.

Features:

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.
