The springloaded roller grinding mill for grinding coal was intro duced by Loesche in the 1920's. Since the end of the 1930's Loesche mills have also been used for grinding cement raw material. The biggest breakthrough in this field of application took place in the 1960's. Soon after this the cement industry expressed the desire to
The dry raw mix is pneumatically blended and stored in specially constructed silos until it is fed to the pyroprocessing system. In the wet process, water is added to the raw mill during the grinding of the raw materials in ball or tube mills, thereby producing a pumpable slurry, or slip, of approximately 65 percent solids.

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.
In the cement industry, natural raw materials are processed to produce an end product which is a fine powder. As shown in the flow diagram, several size reduction processes are needed. The major raw materials are usually quarried, so that they begin the process as geological strata.
World cement production has increased around 20% in the past decade and reached a high of 4100 million tonnes in 2019. The electrical energy consumed in the cement production is approximately 110 kWh/tonne. 30% of the electrical energy is used for raw material crushing and grinding while around 40% of this energy is consumed for grinding clinker to cement powder.

In this chapter an introduction of widely applied energyefficient grinding technologies in cement grinding and description of the operating principles of the related equipments and comparisons over each other in terms of grinding efficiency, specific energy consumption, production capacity and cement quality are given.
For raw materials and cement clinker, the vertical roller mill is an excellent grinding solution because of the relatively lower cost of installation, ease of operation and maintenance, energy efficiency and product quality. Further, our vertical roller mill solution for cement grinding has an ability to dry, grind and separate within a single ...
The accurate prediction of raw meal fineness in the vertical mill system is very helpful for the operator to control the vertical mill. However, due to the complexity of the industrial environment, the process variables have coupling, timevarying delay and nonlinear characteristics in the grinding process of cement raw material.
