1.	What is the main disadvantage of race and ball mill pulverizer?(a) Mill requires extra floor area(b) It is directly connected to the motor(c) High power consumption(d) Greater wearThe question was asked in quiz.My query is from Pulverised Mills in portion Steam Power Plant of Energy Engineering
Answer» Right choice is (d) Greater wear To EXPLAIN: Ball and race MILL have greater wear compared to other pulverizers. The advantages of lower space occupied, lower power consumption in KW hr/ton of coal pulverized, lower WEIGHT and lower capital cost have OUTWEIGHED the wear problem and these pulverizers found general acceptance.
