The balls inside the attritor mill can be made of various materials, but must be stronger than the material to be milled. A vertical centre shaft inside a cylindrical tank is fixed with arms that spin around the shaft at high speed. The arms can vary slightly in design. The tank is partially filled with balls and then the mineral is introduced.
The vertical ball mill has stable performance, supports dry and wet grinding, and has unique performance for coarse and thickened materials. Vertical ball mill can be widely used for dispersion and grinding of solid or powder materials in paint, medicine, building materials, chemical industry and …
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
The patented CLS Attritor Stirred Vertical Ball Mill Lime Slaker operates in continuous processing mode and has been used successfully in power generating plants for flue gas desulphurization (FGD). The Attritor will slake the lime as well as grind the inert grit, eliminating grit separation and disposal problems. Because of its compact size ...
Conway-Baker et al. [] studied the effect of the impeller design on the media motion inside a vertical stirred mill by using Positron Emission Particle Tracking (PEPT).Three impellers were tested: a flat blade, a pin type and down pitched impeller. This work highlighted how the impeller strongly influences the upper and lower recirculation loops inside the mill, and consequently, the packing ...

Milling occurs in a stationary container filled up with a huge number of grinding balls, which are mixed by impellers attached to a vertical drive axis. A major problem experienced using vertical-axis attritor mills for dry grinding is the gravity-driven segregation of the powder to the bottom of the mill [ 59 ].
Aligning the vertical head – tramming. One of the key alignments on a vertical milling machine is setting the vertical head so that it is square with the milling table. This has to be so it is square in the x-z plane and in the y-z plane. All vertical heads, except on the smallest machines, are designed so that they can rotate in the x-z plane.
