energy efficient pre grinding ball mill of ore

Comparison of energy efficiency between ball mills and

01/06/2009  At product sizes finer than 80% passing 75 μm, the efficiency of ball mill grinding rapidly decreases. The practical limit to ball mill product fineness is considered to be 40–45 μm (Gao and Weller, 1994). Although ball mills can still be found in the regrind circuits in a number of mineral processing plants, their energy consumption is high, and size reduction efficiency is low. The need to grind the ore finer to liberate the minerals and the dramatic increase in the cost of energy

Improved characterisation of ball milling energy

15/01/2018  This paper describes a method for assessing the downstream milling energy requirements for high pressure grinding rolls (HPGR) products based on a Bond mill test procedure. Multiple trade-off studies have reported the performance of HPGR versus SAG milling with energy savings of between 11 and 32 per cent. One factor that is often inconsistently defined in these studies is the change in the

Achievement of High Energy Efficiency in Grinding Mills at

SAG Mill Ball Charge The SAG mill was simulated to require a 10-12% ball charge with a top size of 125mm. During the commissioning phase no balls were required to be added to the SAG mill to achieve the target throughput of 575tph. This allows for great flexibility in the future and significant security for the future. Ball Mill Power

The more control you have over the mill, the better your grinding efficiency is likely to be. Our ball mills include monitoring systems to continuously measure the material and air temperatures as well as the pressure at the mill exit. The venting of the mill is adjusted by a damper in the inlet to the mill fan. And the material fill level is continuously monitored by means of sensors. For ball mills operating in closed

Using smaller balls increases grinding ball surface area and, within limits, may allow more particles to be ground for the same amount of energy. Once again gains in ball mill circuit energy efficiency may result. Such opportunities can only be discovered by detailed study of the individual units by experienced comminution practitioners. Once potential operating improvements have been identified, simulations can then be run and the magnitude of the likely gains in energy efficiency
