dynamic balance aggregate crusher drums

Dry coarse aggregate samples are rotated in a large steel drum with an abrasive charge of steel balls. A hardened steel shelf lifts the sample and abrasive charge and drops them against the opposite side of the drum as it rotates, creating an impact-crushing effect. Grinding and abrasion continue as the contents roll in the drum.

Dec 01, · The operation of the Los Angeles drum is therefore dynamic aggregate destruction as opposed to completely static loading when testing the ACV crushing index. However, there are opinions that the test results of the aggregate LA disintegration ratio are consistent with the strength of the concrete from the tested aggregate [ 23 ].

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Oct 01, · The LA abrasion test is the most widely used method for testing aggregate abrasion (Wu et al., 1998).In Australia, the LA abrasion method is available in the Australian Standards (AS 1141.23), whereas other standards, such as ASTM C131/C131M, may be used in other parts of the world.

1.8. Dynamic Model of Crushing Plant A. Gauti ( ) had studied the dynamic behavior in crushing plants and found that there are many factors that effect to plant performance (Figure 5).
