In the raw meal grinding production, the cement raw materials will be ground into finer size to make sure good mixing. In this stage, there are two types of the raw mill to choose, the vertical cement mill uses the pressure leaked by cylinder to crush the passing materials. The cement ball mill use balls to grind the materials. From now on, the ...

Unequivocally no. The concrete adds little or no vibration dampening, no real rigidity, and basically no strength. I went through all of that a number of years ago trying to cure a JET mill drill of nasty vibration. I asked the same question, guys talked about epoxy concrete, hydraulic grout, loose sand, etc.

where d is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
