Introduction Ball mill is an efficient tool for grinding many materials into fine powder. The ball mill is used to grind many kinds of row materials. There are two ways of grinding: the dry process and the wet process. It can be divided into tubular type and flowing type according to different forms of discharging material.
Practical 1: Title: Ball Milling Objective: To grind the coarse salt to a smaller size by using a ball mill and to obtain the particle size distribution of the initial and the sieved final mixture. Introduction: 'Ball milling is a method used to break down the solids to smaller sizes or into a powder. A…
Ball mill is typically used to grind and/or blend materials and it can be done wet or dry. It can be used to mix ceramic powders, disperse particles in solvents, homogenize ceramic slurries, etc. Ball mills operate by rotating plastic jars around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

1) The bowls and balls must be cleaned after your use. Try some acids if they are very hard to clean. Please consult experts to avoid any damage. 2) Put the bowls, caps and balls in oven to dry them, Or flip the bowl to naturally dry it. Note: Never put the flat seal ring in oven. 3) Put all parts on the table for next users.
