Abstract

This invention relates to a bead mill design and provides improved performance and reduced specific power consumption. In the cylindrical grinding chamber 1, the disks are mounted at an acute angle to the plane perpendicular to the axis of rotation of the shaft 2, and provided on both sides with projections with a triangular profile, the surface of the projections facing the direction of rotation being concave. The ground mass, together with the liquid component, is pumped into the nozzle 6 and fills the entire chamber volume. Colliding in opposite flows, the mass is intensively crushed by grinding bodies 5 and by self-grinding during mutual collisions and abrasion. Due to the fact that the distance between the disks 3 from the top down is reduced, a more uniform concentration of the grinding bodies 5 throughout the volume of the working chamber is ensured, which improves the quality of the product and prevents the formation of sludge. The finished product is withdrawn through the grid 7 and the fitting 8. 3 Il. Ј $ (L

Claims (1)

Claim A bead mill containing a cylindrical grinding chamber with means for loading and unloading material, ball grinding media and a vertical shaft coaxially placed in the chamber with parallel mounted disks, on the ends of which there are protrusions of a triangular profile with a concave surface, characterized in that, in order to increase productivity and reduce the specific energy consumption, the disks are mounted on the shaft obliquely with decreasing distance between them from top to bottom, and the protrusions are oriented in the radial direction so that their concave surface is turned in the direction of rotation.
