As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Years of cement production practice shows that cement particle gradation should be distributed continuously within a certain size range. Generally speaking, the cement particles smaller than 32 μm are beneficial to reduce bleeding and early strength, but as the size of particles gets smaller, although the hydration activity increases, the voidage of particles will also increase when they ...

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.

and with the decreased grain size, the necessary ball size also decreases (Olejnik, 2010; 2011). For each grain size there is an optimal ball size (Trumic et. al., 2007). The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In both
