Sep 04, 2013· re Cement Process Quality Control. 1. Mineralogy of Raw Material used for manufacturing of Cement. You need a good deal of reasonably pure limestone (or marble of chalk or othe form of CaCO3); some shale, clay, schist or other material that is mainly composed of compounds of silicon, iron and aluminium.
Feb 23, 2016· Raw mill fans: Raw mill fan in cement industry carries gas and raw meal. The pressure drop in raw mill fan is very high. If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. 4.

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
Details of the raw mill circuit are shown in Figure 5 for a ball mill and in Figure 6 for a Vertical Roller Mill (VRM). The main filter fan pulls the gases through the ducting and the main bag filter/ ESP to the stack. The coal mill circuit for a VRM is shown in Figure 7.
As cement producers continually seek reduced energy consumption and lower maintenance costs, two emerging trends are changing the face of cement production: the use of grinding stations that support variable feed materials and more widespread use of vertical roller mills (VRMs). Cement producers in India, Nepal and Bangladesh demonstrate the success of using VRMs.
ABB Ability™ Expert Optimizer is a computerbased system for controlling, stabilizing and optimizing industrial processes. Due to its stateoftheart optimization technologies the software helps you to make the best operational decisions accurately and consistently at all times.
HOLTEC has undertaken Performance Optimisation of the cement grinding circuits by doing process diagnostic studies in many cement plants. The paper describes the approach for the process diagnostic study for the optimisation of a ball mill circuit and is supported with typical case study done by HOLTEC in a mio t/a cement plant.
Fans for Cement Industry include the preheater exhaust, kiln induced draught, raw mill exhaust, Cooler exhaust, cooler forced draught and cement mill exhaust applications. Quality fans for complete dedusting applications, air slide blowers and axial fans for the shell cooling are supplied by Reitz India.
Instability, where ball mill feed is stopped and the mill ground out, is also infrequently recorded or acted upon. When it comes to mill control, operators rarely concentrate on pushing mill production when the kiln is regarded as the key. Expert systems on mills should be universal and well tuned.
In the modern cement plants, the exhaust gas from the coal mill circuit requires dust control measures. Until a few years back, it was the practice to use coal mill exhaust gas as primary air in the kiln burner and the coal mill capacity was balanced with respect to the kiln requirement.
