How to Improve Grinding Efficiency and Profitability - Indicators of grindability andgrinding efficiency

The ball mill grinding efficiency was poor and could be indicated by the fraction 125 µm of only 5 9 or x. P 80 >400 µm in the mill discharge. This was deemed due to poor hydrocyclone performance which was characterized by higher feed solids content coarser overflow x. P 80 >200 µm as well as cut sizes x.Many studies in the literature indicate that the size of the grinding media directly influences the grinding efficiency. The size distribution of the charge media is related to the surface area of ...

affects their grindability [4]. During machining, fibre particles cause fast tool wear and irregular cutting forces, hence workpiece surface roughness [5]. The grinding process consumes more energy than other machining processes for the removal of a ... parameters for maximized grinding efficiency and minimized surface roughness seems to exist ...Re: Impact of free lime on grinding efficiency. Hello Pankajbits, All other factors being equal, low free lime clinker (hard burned) is generally harder to grind than clinker with higher free lime. This is due to physical changes in clinker mineralogy and porosity caused by over-burning rather than the presence of the free lime itself.
