Effect of Different Grinding Processes on Powder ...
2019-8-1 Commonly hammer mills are used for medium- to hard-to-mill products for grinding process. Tamarind seed is a hard-to-mill material; even some of its seeds may damage the grinding zone of mills. Its seed with higher moisture content may stick inside the grinding zone if the mill is run for longer period.

Effect of ball mill grinding parameters of hydrated
2013-5-1 Operational grinding parameters have marginal effect on fineness of particle. Real surface area enhancement did not occur on the external surfaces, but in the inner surfaces due to lime hydration process conditions. The ball mill load and speed are the most important parameters rather than material charged volume. The undersize percentages of 297, 53 and 10 μm are quality control checkpoints for
