Sep 11, 2013 TITLE: Ball mill grinding.INTRODUCTION Indeed the ball milling means, the reduction of particles to smaller sizes with the help of a ball mill.They are,\ Dry milling Wet milling Generally, this has porcelain or steel ball as the grinding media.Commiution is occurred by several methods in the ball mill grinding.
The long processing time is among the reasons for low efficiency in the implementation of conventional conching and ball‐mill techniques.In this study, the time‐dependent variation of the moisture, particle size, and water activity of dark, milk, white, and compound chocolate (cocolin) samples were modeled using polynomial regression analysis.
The mill performance is evaluated and recommendations are formulated based on the past history of the mill operations, inspections, process measurements, feed/product characteristics and grinding performance, in order to improve mill output and reduction in power consumptions in the ball mill system.
The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit.Each of these performance parameters peaks at different filling values.In order to contin- uously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position.
The results from this study showed that the ball mill load and mill speed are the most important parameters rather than ball mill charged material volume for the fine grinding of the hydrated lime .
