I claim: 1. A ball mill apparatus for the continuous crushing and dispersing of a solid grinding stock which is conveyed along in a fluid, comprising an annular-gap-shaped grinding chamber which is rotationally symmetric with respect to a vertical centre axis, formed between a stator and a rotor coupled to a drive, which chamber has an at least approximately V-shaped cross …

A ball mill is a big chamber used to grind tough materials like ores, chemicals, ceramic raw material, and paints. Moreover, it consists of a cylindrical container (called the barrel). It rotates about its axis with one or more heavy balls (mill balls or beads) that roll around its outer surface.

Ball mills Ball mills are used for dry and wet grinding of different materials such as cement materials, cement, lime, and ceramic materials. PSP Engineering has continuously refi ned the design of its ball mills. Horizontal ball mills have become a reliable part of grinding plants Main characteristics of ball mills seated on shoe-type bearings

Our Ball Mill's compact vessel with comparable amount of balls, results in a milling chamber with almost no dead-space. Less product in the ball mill during grinding leads to a reduction of waste during product changes. Making this generation of ball mills the most effective so far.
