Pulverizing fan is a unit which is simultaneously functioning as a grinding device and a fan conveying the finished pulverized coal by gas flow. Hot gases drawn off from furnace and coal from which the surface moisture is removed (this moisture decreases drying agent temperature at mill inlet) enter the upper part of gas intake mine simultaneously.
The invention discloses a method for manufacturing end disks of a pulverizing wheel of a fan type coal mill, and a welding rotary table for the rear end disk. Produced front and rear disks have small thickness and high wear resistance; and the disadvantages of large material using amount, high operation energy consumption and the like existing in the conventional pulverizing wheel are overcome.
Fan Types Fan and blower selection depends on the volume flow rate, pressure, type of material handled, space limitations, and efficiency. Fan efficiencies differ from design to design and also by types. Typical ranges of fan efficiencies are given in Table Fans fall into two general categories: centrifugal flow and axial flow.
