A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. 15. † The hammer mill operates on the principle of impact between rapidly moving hammers mounted on a rotor and the powder material. 19. † The hammer mill can be either the horizontal or vertical shaft type.
Working of Ball Mill. The ball mill works by introducing the material to be ground into the feed hopper. The material is then pulled into the mill by the rotation of the drum. As the drum rotates, the balls inside the drum strike the particles, breaking them down into smaller pieces. The ground material is then discharged through the discharge ...
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Introduction Ball mills are essential equipment in many industries, ranging from mining to pharmaceuticals. They are used for a variety of purposes, such as grinding and mixing materials, reducing particle size, and preparing materials for further processing. The importance of ball mills in these industries cannot be overstated.
BALL MILL Construction The ball mill consists of a hollow cylinder rotated on its horizontal axis. Inside the cylinder balls or pebbles are placed. Cylinder: Cylinder may be made up of metal, porcelain or rubber. Rubber reduces the abrasion. Diameter of the cylinder ranges from 1 to 3m in pharmaceutical practice. Balls:
