Mass balance - Wikipedia

A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem ...

Modeling and Optimization of Cement Raw Materials

Before cement raw materials are transported into the cement burning kiln, cement raw material blending process is considered as a whole process, thus the grinding process could be seen as part of blending process. For integrity and generality, we consider that the cement raw material blending process includes ball mill grinding process. Then, the mass balance equation of active ingredients SiO

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. The drum is generally divided into two or three chambers, with ...
