PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL OPTIMISATION - CASE STUDY V.K. Batra*, D. Bhaskara Rao** and Raju Goyal*** Holtec Consulting Private Ltd., New Delhi ABSTRACT Grinding technology has been continuously improving with numerous innovations with a view to improve productivity and reduce power consumption.
The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of .
Jul 18, 2016· The consumption of energy by the cement grinding operation amounts to one third of the total electrical energy used for the production of cement. The optimization of this process would yield substantial benefits in terms of energy savings and capacity increase. Optimization of the Cement Ball Mill Operation
CHAENG cement ball mill equipment can reduce energy consumption by 30% and increase the processing amount by 15-20% after transformation. The cement ball mill can perform dry process production and also wet process production, moreover it can do grinding and drying at the same time.
Feb 10, 2016· re VRM vs Ball Mill for Cement Grinding. Specific power consumption- high for ball mill and Low for VRM ; Maintenance costs- high for VRM and low for Ball mill ; Process control/process technology- ball is operation friendlt and simple in operation but VRM requires some PID or .
Hydration products. The products of the reaction between cement and water are termed "hydration products." In concrete (or mortar or other cementitious materials) there are typically four main types: Calcium silicate hydrate: this is the main reaction product and is the main source of concrete strength. It is often abbreviated, using cement chemists' notation, to "C-S-H," the .
So, the raw mix is burnt to produce clinker : the basic material needed to make cement. conveyor Raw mix kiln cooling preheating clinker storage at the plant Raw mill PowerPoint Presentation: THE CEMENT MANUFACTURING PROCESS 1.GRINDING : The clinker and the gypsum are very finely ground giving a "pure cement".
This is achieved in a cement raw mill. The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm. The measure of fineness usually used is the "specific surface area", which is the total particle surface area ...
