Knowledge is Power!
The coal is made into pulverized coal in mill mainly through crushing, shredding and grinding three ways. Among which, crushing process is the most energy-consuming one and the milling process is most consumed. Various mills in the milling process both have the above-mentioned two or three ways, but it depends on the type of the pulverizer to decide the main way. There are many types of pulverizers, and it can be divided into three types, namely low-speedcoal mill, medium-speed coal mill and high-speed coal mill according to the rotating speed of working parts. Overpressure trapezium mill produced by Henan Hongxing belongs to the high-speed high-quality and efficient milling machinery.
Technical advantages of overpressure trapezium mill:
1, it is with innovative roller and grinding ring design. Compared with Raymond mill, its roller and grinding ring are designed to be multi-level ladder-like, it reduces decline rate of materials between trapezoidal rollers and grinding ring, extends the rolling time of materials by roller and improves the fine degrees and production of finished products.
2, it adopts efficient balanced pressured spring. Overpressure trapezium mill absorbs the advantages of raymond mill and suspended roller mill to combine roller assembly and the placed spring together with pull rod. The radial force generated during which avoids large pieces of materials falling into the grinding chamber and damaging main shaft and bearing, improving the service time of machine.
3, the host machine and classifier.html">classifier use soft links; the damping spring and sealing tape not only reduce vibration and noise, but also avoid the resonance.
4, it adopts high-density and high-precision impeller device.
5, it has energy efficient centrifugal induced draft fan. Fan plays a crucial role in the entire operation of the mill process, trapezium mill adopts efficient energy-saving fan, greatly improving efficiency compared with the straight blade fan.
6, overpressure trapezium mill makes the gap adjustment between classifier blades end and shell convenient, greatly improving the accuracy of finished products.
