The effect of grinding on the acidulation of phosphate

An investigation was undertaken to determine the effect of grinding on the acidulation of phosphate rock. Bench-scale work was carried out in a one quart, laboratory ball mill made of stainless steel. The mill was equipped with a heating chamber so that the material could also be dried in the mill;The results from this work indicated that a normal superphosphate product Get price

High Energy Ball Mills Instead of Planetary Ball Mills

What was the background for the development of your High Energy Ball Mill, the Emax? In laboratories worldwide, Planetary Ball Mills are frequently used, for both, quality control and RD. They have a reputation to be the best mills to grind semi-hard to brittle samples to very fine particles in the nanometer range 100 m, always depending on the samples properties.Get price
