How Temperature Affect Grinding Efficiency

2017-10-24  Polyurethane foam insulation was used to help keep the mill at a uniform temperature. The ore was crushed and mulled to the size distribution given in Table 1, and each experiment used a 5.0 kg charge in 2 liters of water. Six experiments were conducted consisting of three sets of duplicate tests at 2-9°C, 24-26°C, and 84-62°C.

However, the process of comminuting the regrind sometimes proves to be a problem, as many materials have a high temperature sensitivity and tend to melt. In the case of spices, aroma and flavors can be lost due to the high temperatures involved in the grinding process. To prevent these negative consequences with soft, flexible or oily materials, cryogenic grinding is brought to bear.

In Grinding, Coolant Application Matters

2008-03-01  Often the engineer is grinding stringy and ductile materials, such as medical stainless, Inconel, and titanium, and they are seeing the benefit of wheel cleaning as much as cooling. However, the general consensus is to use 600–800-psi (2–5.6MPa) coolant at 2 gpm per inch (0.3 L/min/mm) for bonded wheels, and up to 1500 psi (10.5 MPa) for single-layer wheels.
