Ball charge loading
Abstract: In determining the proper mill size required to meet a targeted production rate, many factors are evaluated including: length to diameter (L/D) ratio, individual compartment lengths, rotational velocity, liner type, ball gradation and percent filling degree. This paper examines the effects of changing mill filling degree with respect …

AP-42, CH1.8: Bagasse Combustion In Sugar Mills
1.8.1 Process Description1-5. Bagasse is the matted cellulose fiber residue from sugar cane that has been processed in a sugar mill. Previously, bagasse was burned as a means of solid waste disposal. However, as the cost of fuel oil, natural gas, and electricity has increased, bagasse has come to be regarded as a fuel rather than refuse.

Modeling of operating parameters for wet ball mill by …
Load of the ball mill affects the productivity, quality and energy consumption of the grinding process. But sensors are not available for the direct measurement of the key parameters for mill load (ML). A new soft sensor approach based on the shell vibration signals to measure the operating parameters is proposed in this paper. Vibration signal is first transformed …
