### Major Mines Projects Holt Mine

The Holt Mill was constructed in 1988 and was originally designed for a throughput of 1 360 tpd. Expansions in 1988 and 2001 increased the throughput to 2 500 tpd and 3 000 tpd respectively. Surface ore storage is a total of 4 900 t in three silos the Holt headframe bin (900 t) and two other separate storage bins (1 000 t and 3 000 t). Sep 01 2013 · A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors including the feed size the product size the mill diameter and the breakage parameters.

### Mill power draw modelsSAGMILLING

Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models. The ball mill is the most common ore grinding technology today and probably more than 50 of the total world energy consumption for ore grinding is consumed in ball mills.
