Cement Mill Plant
Cement Grinding technology
Grinding technology has been continuously improving with numerous innovations with a view to improve productivity and reduce power consumption. In order to reduce the manufacturing costs for cement, it is very important to optimise the existing mill installations as far as the grinding process is concerned and also to use high quality spare parts and consumables like grinding media.
Cement Ball mills
Ball mills are predominantly used machines for grinding in the cement industry. Although ball mills have been used for more than one hundred years, the design is still being improved in order to reduce the grinding costs.
SBM Cement Mill Plant
Cement Mill Plant
SBM 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 SBM in a 1.5 mio t/a cement plant.
The paper also describes the principle of the mill load control system developed by the Holderbank Engineering Canada Limited (HEC), Canada for the optimisation of the performance of the ball mills for obtaining maximum production and minimum specific energy consumption.
Cement Mill Plant Introduction
The need for process optimisation through diagnostic studies has been increasingly felt as production costs are shooting upwards in conjunction with increased competition in the market. In order to reduce the manufacturing costs for cement, it is very important to optimise the existing grinding installations.
Cement Grinding System
Experience has shown that the potential for optimisation is greatest in the cement grinding process in a cement plant The benefits that can be achieved due to the optimisation of cement grinding system through process diagnostic study are:
• Reduction in specific power consumption
• Increase in production
• Stable and sustained operation
• Increase in availability of the equipment – Less down time
• Improved and consistent product quality
• Conventional tube mill – Open and Close circuit
• Tube mill with precrushing unit i.e. vertical shaft impactor (VSI) or horizontal impact crusher (HIC)
• Roller press in semi finish and finish grinding mode
• Vertical roller mill (VRM)
• Ring roller mill or Horo mill
Even though there are various types of systems available for cement grinding, ball mills are predominantly used machines for cement grinding in large number of cement plants. In this paper authors are covering the process diagnostic study of Ball mill for cement grinding.
