the alpine atr agitated ball mills are ideally suited for the dry production of superfine mineral powders < 10 µm. Products with fineness values of up to 95% < 2 µm and a high …

The increased metal wear of grinding media and mill liners for wet grinding equalizes the additional energy costs of the dry grinding procedure. When dry grinding cement raw material, a protective coating of ground material covers the mill liners and grinding balls. It is known that cement raw material is much less abrasive than cement clinker.

RETSCH offers the largest selection of laboratory ball mills in the market! Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials.

 — In ball mills, the grinding of ore bodies takes place due to the impact and attrition of the colliding balls. For efficient grinding of hard materials, high-impact velocities are required. For a given rotating speed and filling of the mill, impact velocities of balls and the nature of forces developed inside the mill can be controlled by the ...

 — The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency …

Glass ball mills are ideal for grinding of pigments in mills vertically and also horizontally. Glass ball mills are particularly suited for applications in mills because of their specific mass which can process low and medium viscosity mill bases. The glass beads, that is, the glass ball meals are thermally and chemically treated to maintain ...
