• Ball and Race Mill ~ ME Mechanical

    In this ball and race mill, coal is pulverized by a combination of’ crushing, impact, and attrition between the grinding surfaces. The advantages of ball and race mill are as follows: Lower capital cost; Lower electricity power consumption; Lower workspace required; Lower weight. However, in ball and race mill there is greater wear as compared to other coal pulverizers. The usage of pulverized coal as a fuel
