A series of abnormal phenomena emerging in normal operation conditions of the medium speed pulverizers in a 600 MW unit are introduced. The effects of the primary air (PA) mass flow and nozzle ring passage area on the pulverizer rejects (PRs) discharge are analyzed. The results indicate that the root cause of all these abnormal phenomena is the lower nozzle PA velocity led by the narrowed ...

Of Coal Mill Discharge Abstract modification of coal mill discharge abstract. Pulp and paper mills generate varieties of pollutants depending upon the type of the pulping process. This paper is the state of the art review of treatability of the pulp and paper mill wastewater and performance of available treatment processes.
Apr 22, 2016· The active coal mine discharge was dominated by sodium and bicarbonate ions compared to magnesium and sulphate ions in the closed mine drainage. Although both receiving waters were sodium and chloride dominated upstream of the mine waste, their ionic composition was strongly modified due to the inflow of coal mine wastes.
Grate Discharge Ball Mill: This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill. A Grate Discharge Mill will also have 15—25 % higher capacity per volume unit as compared with an Overflow Mill.
