### Calculation of energy required for grinding in a ball mill ...

Jan 01, 1989 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 formula ...

### MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

• Ball mill specific grinding rate • Ball mill grinding efficiency The circuit output is defined as the production rate of fines by the circuit. It is calculated from three values: 1. The dry ore feed rate to the circuit (t/h). 2. The % fines in the circuit feed. 3. The % fines in the circuit product. Use this equation to solve for circuit ...

### Calculate Top Ball Size of Grinding Media - Equation Method

Apr 04, 2018 Although it was developed nearly 50 years ago, Bond‘s method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding circuits.

### Calculate and Select Ball Mill Ball Size for Optimum Grinding

Apr 08, 2021 In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

### Experimental Study on the Grinding Rate Constant of a Ball ...

The grinding rate constant is one of the important factors needed to measure or evaluate a grind ing process. It has been found that the decreasing rate of the feed size is described by a first-order equation in the initial grinding stage of various mill types. In this study we conducted grinding tests on silica glass using a ball mill, and ...
