Several basic assumptions are made in modeling of the grinding process in various types of mills and milling circuits. Most frequently, it is assumed that the mill's content is uniform and thoroughly mixed by the rotation of the mill and the movement of the grinding media [44]. In this case the model is known as a perfectly mixed model.

Selecting the correct angle grinder for concrete grinding purposes is very important. You can choose either a 4inch angle grinder or one that is 4 ½ inches. These are considered the best for most concrete grinding tasks. It may also be a good idea that you choose a tool with a motor that is able to draw anywhere between 5 9 amps.
