The energy efficiency of ball milling in comminution

The energy efficiency of ball milling in comminution

Nov 01, 2002 Because the size distribution of comminuted products are self-similar, Fuerstenau and Kapur (1994) defined an energy efficiency in terms of the median size of the product: (2) Energy efficiency =[E m (SP)/E m (Mill) to produce same X 50]100 where E m (SP) is the specific energy required to produce a product of a given median size X 50 by single-particle comminution and E m (Mill) is the specific energy to produce the same median size in a comminution machine, such as a ball mill. …

Estimated Water Requirements for the Conventional

heat generated in the crusher. At most operations, water is sprayed into a crusher and onto conveyor belts to suppress dust in the plant, but this usage represents only a small fraction of the plant’s total water usage. The crushed ore is transferred to a semiautogenous (SAG) mill or ball mill where the ore is further reduced in size.

How to Calculate Power Based on Force and Speed dummies

How to Calculate Power Based on Force and Speed dummies

In physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. However, the object’s speed, v, is just s divided by t, so the equation breaks down to.

TECHNICAL How to Spec a Mill Gear Power Transmission

TECHNICAL How to Spec a Mill Gear Power Transmission

Autogenous mills are the largest in diameter since the feed grinds itself. A semi-autogenous mill uses some metallic or ceramic balls to assist the grinding process and can be slightly smaller. Ball mills are smaller still and use a larger percentage of balls to perform most of the work. Large-di-ameter mills allow for use of gear ratios
