The mill (2) is constructed from a steel drum mounted on a mill rig (11). It is driven by a 2.5 kW variable speed motor (10) via a chain drive (9).The speed of the motor is controlled electronically through a speed controller (tachometer) and can run up to approximately 100 rpm.The milling cylinder (2) measures 550 mm in diameter (inside liners) by 400 mm long …Ball Mill Power Calculations A nice and pretty online Ball Mill Power-draw Calculator was put live by one of the great prophets of grinding. comes with all the related Online documentation prompting you to enter your basic mill data.

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.
