Misalnya pada Pulverizer, biasanya batu bara yang dengan flowrate 65 ton/jam mampu menghasilkan steam hasil pembakaran dengan temperatur 540C. Namun, ternyata dengan flowrate yang sama, temperatur dari steam menurun, salah satu penyebabnya bisa jadi berkurangnya asupan fine coal dari pulverizer. Karena itu pulverizer harus diperiksa Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coalBoilers machinery : Coal Pulverizer Mitsubishi Heavy Industries, Ltd.

Vertical Grinding Mill (Coal Pulverizer) Explained saVRee
Coal Pulverizer Purpose. Irrespective of the machine used to pulverize the coal, all coal pulverizers have a similar purpose. Coal pulverizers are used to dry, grind and classify. Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases used should have a low oxygen content, thisThe more recent coal pulverizer designs are Vertical Roller Mills. Figure 2 shows a cutaway view of a Babcock and Wilcox MPS Pulverizer.

Dynamic Pressurized Rotating Classifier The rotating classifier offers coal flow and fineness Associated minerals in the raw coal increase the energy consumption and abrasion of grinding media of vertical spindle pulverizer (VSP). Moreover, the low separating efficiency of classifier in VSP leads to the return of fines to grinding table, worsens the grinding phenomenon and make the energy-size reduction of coal complex.Loesche vertical roller mills for the comminution of ores and minerals
