Typically the ball mill was placed on an upper floor so that material could move by gravity. An example was the original rawmill system at Aberthaw. Four Ernest Newell ball and tube sets were provided to serve two kilns. The ball mill by this stage used forged steel balls as grinding media and had its outlet in the form of grids in the end wall.
For this reason, the rawmill is usually placed close to the kiln preheater. Types of dry rawmill include ball mills, roller mills and hammer mills. Ball mills. These are similar to cement mills, but often with a larger gas flow. The gas temperature is controlled by coldair bleeds to ensure a dry product without overheating the mill.
This relationship was successfully used for the scaleup of a rocking ball mill, and the optimum design and operating conditions for the rocking ball mill could be estimated by the specific impact energy of the balls calculated by a computer simulation.
