Mill power draw increase Chalenge Draw more power, increase throughput, and maximize production with your existing mill. Your challenge Mills are originally sized for specific running conditions. Declining ore grades and increasing hardness makes supporting the market demand more challenging.Ball mill power draw predicted from the Denver slide rule, kW 0 200 400 600 Calculated ball-mill power draw from the m odel derived, kW Data compared Line y=x Fig. 2. Comparison of the ball mill power draw from the Denver slide rule and the proposed model.

Mill power models have been used in a variety of ways in industrial practice since power directly equates to throughput and fineness of ground product. We first start with Hogg-Fuerstenau Power Model and show how this model successfully predicted the power draw of many grinding mills in several mining operations. Then, we show how this model was on the …ball mill power draw pi Ball Mill Design/Power Calculation Jun 19, 2015 The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution.

The Morgärdshammar equation and the IMM equations are shown for comparison. The method of use is similar to the AM section 3.3 Ball Mill Design The ball mill designs also follow the Bond/Rowlings method with comparison with other methods. Again the method of use is the same

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. Models of this type do not predict the particle size ...For example, the D:L ratio for 32 ft dia. mills decreased from 3.00:1 to 2.17:1 over 35 years until the advent of 36 ft dia. mills in 1973. The D:L ratio for 36 ft dia. mills decreased from 2.53:1 to 2.06:1 over 23 years until the first 38 ft dia. mill was purchased in 1996. The 38 ft dia. mills are 1.87:1, with special cases at Freeport (2.08:1)
