2020-5-21In addition to wear speed ball sie and recharge practice charge volume and feed rate are significant factors affecting the actual production wear rate. Wear speeds are largely independent of ball sie and ball charge volume. The wear rate exponent for SAG milling was experimentally determined to

2009-8-27The process design of gold leaching and carbon-in-pulp circuits contaminants. These are removed by thermal regeneration of the eluted carbon typically in a rotary kiln at temperatures of 650750C. Regeneration is carried out in a steam atmosphere to minimie carbon degradation due to oxidation. The eluted and regenerated carbon is screened

2018-6-5For a given waste material the key parameters affecting the incineration process include gas-solid contacting tem-perature and time. The importance of temperature makes heat transfer calculations useful for estimating the effects of kiln design and operation on burden temperature. This pa-per presents a mathematical model of heat transfer in

2019-5-25A promising approach in the selective separation and modification of cellulose from raw biomass under a mild alkali process was proposed. In our study ball milling was applied to wheat straw prior to alkali treatment. With ball milling ultrafine powder formed an amorphous microstructure and displayed a level of solubiliation in aqueous NaOH higher than that of general ground samples. Alkali

On the other hand the fineness of the material at the mill outlet depends mainly on the retention time of the material in the mill. The main influencing factor on the retention time is the mill length. Therefore the ratio of length to diameter LD of a mill is an important factor for an optimal design of the mill

Typically bottlenecks in a circuit can be found in the equipment for comminution transportation or classification. They are possibly preventing crushing screening and milling equipment from operating at their optimum performance levels. In the first post of the series we covered the importance of measurement and assessments to increase value per tonne. Here we will take a deeper look on
