Although the importance to achieve steady-state in a grinding test is widely accepted Bond tests, the MacPherson test remains the only small-scale AGSAG mill test that offers this option. Steady-state is especially important in AGSAG mills where a harder component can build up over time and negatively affect operations.
A proprietary process that involves multi-pass grinding and pinch finish grinding is used which has been developed over many years of testing. Dimensional tolerances can be maintained over long or short production runs with the help of in-process measurements and automatic compensation for wheel wear and for changes in ambient temperature.
Grinding is a material removal and surface generation process used to shape and finish components made of metals and other materials. The precision and surface finish obtained through grinding can be up to ten times better than with either turning or milling. Grinding employs an abrasive product, usually a rotating wheel brought into

The grinding experiments were carried out on four typical samples of iron, copper, manganese and leadzinc ore with three test-sieves in specified time periods and aimed to shortening the procedure.
The industrial pin mill also known as a universal mill, turbo mill, and impact mill is a one pass grinding equipment ideal for achieving the micronization of bulk materials and powdered products. Common applications involve the fine grinding of sugar, salt, sodium bicarb, etc. The average achievable particle size range of the pin mill is around a d50 of 80 microns.
Pinch grinding offers accurate geometrical dimensions on the blank and tight surface finish requirements. In pinch grinding, the roughing and finishing wheels grind parts simultaneously, with the finishing wheel trailing the roughing wheel. The
Pinch grinding is suitable for grinding products such as precision punches, micro pins, and mold components. The purpose is to have minimal contact between the wheel and the workpiece in order to reduce the introduction of heat. With pinch grinding, part deflection is minimized. It can do both roughing and finishing operations simultaneously.
