ORGANIZATIONAL RESTRUCTURING AND OPTIMIZATION OF THE MAINTENANCE PROCESS IN A CEMENT PLANT ALPHA CEMENT GROUP, RUSSIA Holcim is one of the leading cement producers in the world. Holcim together with Alpha Cement Group operates two cement plants in Russia: one in Shurovo, the other in Volsk. The Shurovo plant with approximately 800 employees produces 1,0 million tons of cement .
Entire process of cement production is subdivided into several unit operations like Raw materials, Crushing, Raw materials grinding, Pyroprocessing, Cement grinding, Packing dispatch etc. Further each unit operation is studied in details with an objective to identify the potential improvement areas for optimizing the operational practices. A special emphasis is laid on achieving the ...

Energy optimization in cement manufacturing Reprint from ABB Review 2/2007 Cement producers are large consumers of thermal and electrical energy, which on a global level are only available at steadily increasing costs. Efforts to reduce demands by using higher effi ciency equipment and substituting fuels and raw materials to lower production costs have been addressed in recent years. These ...
Production planning plays an important role for a manufacturing industry as it relates to the manufacturer''s plan to meet product demand, profit achievement, and use of resources. An improper planning can lead to costs that are not expected. This
the cement industry planning process is centralized and optimization oriented. There is no constraint in the availability of cement main raw materials with the exception of some countries where subsoil ownership regulations applied. Cement manufacturing is capital and energy intensive where cement truck delivery is restricted due to its low valuetoweight ratio. quarries: HIGH • Oligopoly ...
This paper shows that important technological benefits such as monitoring of cement manufacturing and prediction of the finished product behavior can be assessed by analysis of portland cement clinker microstructure. In fact, raw meal travelling
· Cement Manufacturing Process Phase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide. High temperature of kiln ...

Introduction. Cement production has undergone tremendous developments since its beginnings some 2,000 years ago. While the use of cement in concrete has a very long history (Malinowsky ...
Controlled parameter optimization of this 5000 MT/D production line was then carried out. As a result, ... whole cement production system have not been su ciently carried out. This paper proposes that the scope of research should be extended from a single device or certain process to the whole cement clinker calcination system (the whole system) while analyzing the thermal e ciency of the ...
This paper focuses on modelling and solving the ingredient ratio optimization problem in cement raw material blending process. A general nonlinear timevarying (GNLTV) model is established for cement raw material blending process via considering chemical composition, feed flow fluctuation, and various craft and production constraints.
cement production is as low as 6 per tonne in China as opposed to 30 per tonne in Nigeria; this has contributed largely to the high and persistent rise in unit cost of ce ment production. There is thus the need for the adoption of energy efficiency in cement production in Nigeria. Recently, there has been an increasing interest in using energy analysis techniques for energyutilization ...
