The cement mill
Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

Grinding Media Wear Rate Calculation in Ball Mill
In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight. Since the amount of ore crushed varies as …

Concrete Mix Calculator
For example, let's calculate the amount of cement, sand, and gravel for the M5 mix to fill one cubic yard of space. Start by calculating the dry volume of the mix. dry volume = 1.0 × 1.54 = 1.54 cu yds. Recall the percentages for this mix are: 1 part cement -> 1/16 = 0.0625 5 parts sand -> 5/16 = 0.3125 10 parts gravel -> 10/16 = 0.625. Now, multiply each of …
