Mill Feed Sep. Return Final Product System Fan Figure 1: Closed circuit grinding system. milling system is a delicate task due to the multivariable character of the process, the elevated degree of load disturbances, the different cement types ground in the same mill, as well as the incomplete or missing information about some key process charac
The paper presents the design procedure of a modelbased control algorithm for the regulation of tailings and product flowrates in a cement mill. The control variables are the feeding rate and the classifier speed. Experimental results of a fullscale industrial application are reported and discussed with a view to the control of the fineness of the cement.
cement mill optimization. i have a polysius ball mill with capacity 110 tph. normally i get blaine at mill outlet around 200 while my product blaine target is 400 . separator reject baline is around 90 . i think i should put more smaller grinding media in ii chamber to increase the fineness at mill .

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.
Jul 31, 2014· CONCLUSION There is a scope for significant optimisation of the traditional cement grinding circuits. Grinding process modelling and simulation methods can be used for optimisation. A case study conducted using the data from an industrial cement plant indicates that: • Precrushing of cement clinker using a Barmac crusher offers realistic ...
Over the past 15 years, minetomill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding. Minetomill optimisation: effect
