Abstract:

Aiming at the problems of  low grinding production capacity，low efficiency of mill，low classigication efficiency of cyclone，high consumption of steel ball and energy，grinding research and industrial applications were carried out in Dayingezhuang gold mine，by using the technology of accurate ball loading and addition，and  a good effect of increasing production and reducing consumption was achieved.The results show that the production capacity of the mill increased by 5.01%，electricity consumption decreased by 7.88% and the grinding media consumption decreased by 6.84%.Mill efficiency increased by 9.16% and 10.45%，respectively.Cyclone classification efficiency has been increased by 4.94% and 4.07%，the mass transfer efficiency of cyclone classifier increased by 3.51% and 3.90% respectively.The -0.074 mm product of cyclone classification increased by 0.52%，-0.010 mm content reduced by 3.5%.Concentrate grade and recovery has been improved.The results indicated that the increasing production of mill has a remarkable economic benefit，so it has the value of popularization and application.
