Primarily for cement grinding plants in India, coal (generally of bituminous grade) is used in the slag-dryer. The wet slag arrives at the stack on wagons from some nearby steel plant, or it may be brought via a trolley-system (primitive mode). But, this wet slag cannot be directly put into the ball-mill (where grinding is done) as.

Coal is the main fuel for both the kiln and the preheater tower. The coal is ground in a 1000 hp KVS ball mill with a Polysius SEPOL dynamic separator. This coal mill system has a production rate of 20 T per hour (22 t). The pulverized coal is conveyed to and stored in a 200 T (220 t) coal bin. Two Pfister rotary weigh feeders.
Oct 21, 2011 . Inerting systems avoid dust explosions and smouldering fires in silos, coal mills and filter equipment by creating an inert atmosphere. In the case of abnormal levels of carbon monoxide (CO), oxygen or heat, the inerting process is initiated automatically through a process-control system. Constant and.
Coal mill bag filter DP high & chocking problem. Dear expert. I am facing problem of coal mill bag filter DP high & bag damage problem after using tyre dust grinding with pet coke in coal mill. Can any method of grinding & mixing of tyre dust with other fuel without dust pollution. How to arrange purzing cycle.
The material to be ground is fed into the mill from its top. It falls on the table placed at the bottom of the mill. Due to the centrifugal force generated by the rotation of the main shaft the grinding rollers are pressed closely upon the grinding ring and grind the material fed into the mill (raw, cement or coal for instance) as they roll.
