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

other parameters such as hammer pattern and screen size can be changed, the tip speed and available screen area are determined with the machine purchase. In,so fine grinding may be required in order to achieve a reasonable pellet quality. Swine have

Grinding Wheel Selection for Cylindrical Grinding The listing of grinding wheel specifications for commonly used materials (on page 80) serves the purpose of general information only. It may be used as a first approach in grinding wheel selection for cylindrical grinding operations, should more pertinent data, as from comparable past operations, not be available.
