Bulk material movement involving sliding very often causes heavy wear of the equipment used, resulting in damage to equipment, lower reliability, production losses, and lower capacity utilization.
An inverted cone is positioned inside of the inner cone to reduce the velocity of the transport medium entering the inner cone through .the cone spout and ensure that the heavier coal particles are not prevented from returning to the bowl. The exiting coal air mixture passes through a

Alumina Ceramic Lined Coal Pipe Lines & Bends. Coal and air from pulverizer to Coal Burner Nozzles flows between outlet pipes and bends. Due to high velocity 25 m/s and abrasive nature of coal pipe lines experience erosive wear. This wear can be substantially reduced by fixing Alumina Ceramic Liners.

Reconditioned 372 C-E Raymond Bowl Mill Coal Pulverizer rated at a base capacity of 6,200 Lbs/Hr. on 55 grindibility coal pulverized to 70% minus 200 mesh. Mill is capable of grinding down to 90% minus 200 mesh as well as grinding a 40 hardgrove but at a lower rating. ... static classifier with inner cone and inverted cone, side mounted feeder ...
This concentrates the oversize material along the surface of the upper inner cone, where gravity causes it to flow into the lower inner cone and then out the tailings spout at the bottom. The air stream carrying the powdered material of required fineness moves through the fan and is delivered into the outer cone chamber where the fines are ...
According to different grinding requirements, ball mill liners are roughly divided into 9 types, which are wedge-shaped, corrugated, flat-convex, flat, stepped, elongated, rudder-shaped, K-shaped ball mill rubber liner and B-shaped ball mill rubber liner. These 9 kinds of grinding mill liners can be classified into two categories: smooth grinding mill liner and unsmooth grinding mill liner.
