  • Types of Boiler Coal Pulverizers - Bright Hub Engineering

    Attrition TypeImpact and Attrition TypeImpact Or Hammer TypeCoal is fed into a rotating cylinder containing steel balls of around 50 mm diameter. When the cylinder rotates, the balls rotate along with the cylinder and fall down when they reach the top position. Coal is ground due to attrition and impact. Coal feeds into the cylinder axially at one side and discharges through the other side. Hot air or gas carries away the fine coal through the other end of the Tube. This called the “Tube mill” or “Ball mill.” These types of mills have: 1. Initial costs that is higher. 2. Maintenance that is
