EP1593436A1 - Centrifugal mill - Google Patents

The mill is driven in a housing (2) which has a blow-out pipe (7) for discharging the ground material. At least one element (11) is inserted in a region of the blow-out pipe in order to influence the flow and prevent blockage. An element for influencing the flow can also be used in a region of an inlet pipe of a meal container on the outlet side of the housing.

Grinding mechanism of centrifugal mills — a simulation ...

Mar 01, 1996  2. Model and simulation In a partly filled mill, the ball media are considered to grind the material in the mill body by impact force due to collision of the grinding bodies and attrition between the grinding bodies. In modeling such mills by micro events the first problem is to represent the physical events by kinetic equations.

Styles of centrifugal pumps used in pumping carbon to ...

Aug 01, 1991  Attrition of activated carbon in either the carbon-in-pulp (CIP) or carbon-in-leach (CIL) method of gold extraction can lead to, at the least, loss of expensive carbon that has to be made up, and at the worst, loss of both the carbon and any gold that was attached to it. Carbon attrition therefore represents a significant factor in both the efficiency and cost of the extraction process, and ...
