Charge behaviour and power consumption in ball mills:
Discrete element method (DEM) modelling has been used to systematically study the effects of changes in mill operating parameters and particle properties on the charge shape and power draw of a 5-m ball mill. Specifically, changes in charge fill level, lifter shape (either by design or wear) and lifter pattern are analysed. The effects of Effective mill power draw 24 Ball mill specific grinding rate 29 Ball mill grinding efficiency 33 Progress Review 1 39 PART II You will need a calculator to complete this module.

AG Autogenous & SAG Semi-Autogenous Mill Design Calculations
Product Size: All passing 6 mesh with 80% passing 20 mesh. Net power from pilot plant: 16.5 KWH/ST. Mill, gear and pinion friction multiplier: 1.025. Mill Power required at pinionshaft = (240 x 16.5 x 1.025) ÷ 0.746 = 5440 Hp. Speed reducer efficiency: 98%. 5440 Hp ÷ 0.98 = 5550 HP (required minimum motor output power).At the end of this lesson students should be able to: Explain the role of ball mill in mineral industry and why it is extensively used. Describe different types of ball mill design. Describe the components of ball mill. Explain their understanding of ball mill operation. Explain the role of critical speed and power draw in design and processAMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill Operator

Calculation of energy required for grinding in a ball mill
INTRODUCTION The energy consumption for grinding, according to Bond (1961), is deter- mined by the formula: / 10 10 (I) The work index is determined by grinding experiments carried out in a labo- ratory Bond ball mill. Based on the results of grinding experiments, numerical values of the work index Wi are calculated according to the on ball motion in mills using the discrete element method has been proposed by Mishra et al.2) and Yanagi et al.3) So far, reports on analyses simulat-ing three-dimensional analysis and complex liner shapes,4), 5)and research on mill power consump-tion 6), 7) have been published.

AUTOMATION AND OPTIMIZATION OF COAL GRINDING BY MEANS OF BALL MILLS
improvement of grinding capacity of the mills in such a way that the capacity of two mills was enough for preparation of the fuel for the power generating unit and the third mill was turned off. This is how energy saving by 30 % at coal grinding was reached. 3. CONCLUSION . The ball mill control and optimization system underSince for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal to1.20.
