Energy Management in Small and Medium sized Re-rolling mills

Jun 19 2017 · Use of lower capacity motor reduces the consumption of electrical energy of the mill. Fig 1 Time speed relationship of electric motor and fly wheel at time of start. Non coking coal with a CV in the range of 6500 kcal/kg to 7000 kcal/kg is a preferred coal in these re-rolling mills for the combustion in the reheating furnace. The MPS mill also grinds dries calcines and classifies gypsum without any problem all in a single machine for any fineness requested and considering individual requirements. The MPS vertical roller millbuilt to last reliable and energy-efficientis the optimum solution when it comes to performing several process steps in one unit.
