Fine coal air mixture leaves the mill and enters the fuel piping system. Tramp iron pieces which are not required to grind, leave the Bowl due to centrifugal force and are removed through the reject removal system. Bowl Mill Nomenclature / Designation Suction type mills are designated as XRS whereas pressurized mills as XRP and HP.

What is mill fineness? The rolls do not touch the grinding ring even when the mill is empty. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance.

The present paper discusses an innovative means for solving the problem of accumulation of waste coal in some pulverized coal fired plants. A major waste in a pulverized coal fired power plant is the reject produced from pulverizing mills. When coal is ground in a bowl mill heavy mineral matters are separated, but they still contain a small amount of coal mixed. However, the heating value of ...

The ground coal is picked up by an air stream entering the mill through a Port Ring on the periphery of the Grinding Table; • Air entering through the Port Ring creates a fluidising zone in which 'heavy material' (Mill Rejects) such as rock falls through the Port Ring into the Air Plenum below the Grinding Table and is ejected from the Mill through the Mill Reject System;
