  • Best energy consumption International Cement Review

    The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill circulating loads of >1000 per cent Manufacturers have countered this generally satisfactorily with pressure drops reduced by lower nozzle ring velocities and the addition of external spillage elevator recirculation systemsThe basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closedBall Mill Design/Power Calculationgrinding mills power consumption kw grinding mills power consumption kw Electricity power conservation in cement productionFacility Efficiency Description Vertical Raw Mill Reducing% of specific power consumption for milling Compared to conventional ball mill Waste Heat Recoverygrinding mills power consumption kw,MODELING THE SPECIFIC GRINDING ENERGY AND MODELING THE SPECIFIC GRINDINGthe specific grinding energy and ball

  • Energy Consumption in Mining Comminution

    · Energy consumption is described by kWh/tonne with mill efficiency is described by kW/m3 and material throughput described as t/h (tones/hour) Whereas crushing is usually a dry process, grinding is usually performed wet to provide a slurry (liquid) feed to the chemical concentration process [15] With rock reduced to a manageable size by crushing, grinding mills then reduce the rock eventhe SAG mills throughput, power consumption and accordingly, specific energy The feed size distribution together with the ore characteristics (hardness, lithology, alterations, etc) are the most important factors affecting the SAG mills performance Some operations have recognised an opportunity in the relationship between feed size and mill performance and manipulate feed size to obtainModelling SAG milling power and specific energySp power consumption kWh/t 4418 4356 4120 4200 Product blaine m 2/gm 270 273 272 274 The mill was operating at an average output of 135 t/h OPC and specific power consumption of 4273 kWh/t OPC 33 Observations and Diagnosis • The cement mill and the sepax separator were thoroughly inspected to observe internal condition of the mill and separator During the inspection, mill andPROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL
