to include SAG and Ball milling. The hardness of each sample was measured in terms of SAG power index, SPI (for SAG grinding) and Bond Ball mill work index, BWi (for ball mill grinding). A further measure, the Minnovex crusher index, Ci was also measured for use in the CEET program to determine SAG mill feed size (Kosick and Bennett, 2001).

view moreWorking Principle & Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the

Order of magnitude estimate: An order of magnitude estimate is a rough estimation of costs used at the very early stage of a project, particularly during the evaluation and planning stages.The purpose of this type of cost estimation is to have an idea about general and total expenditures instead of itemizing expenses based on project

view moreBall mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
