Ball 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.
Capital costs for construction projects - Designing Buildings Wiki - Share your construction industry knowledge. Capital costs are costs associated with one-off expenditure on the acquisition, construction or enhancement of significant fixed assets including land, buildings and equipment that will be of use or benefit for more than one financial year.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

1-6-2005· Anyway, SAG mills can be calculated as inefficient, except they do not require a large grinding load like ball and rod mills. Capital and operating costs have to be compared, system vs. system in order to assist with the selection. The feed suitability vis-a-vis the grind method is critical.
