Used to crush aggregates, core samples and similar materials when a reduction in sample size is necessary. The crusher has a jaw opening of 100x60 mm and can produce from 100 to 400 kg of material per hour. The movement of the jaws can be adjusted from 2 to 18 mm. The crushed sample can be further reduced using the hammer-mill for laboratory.

TESTING OF AGGREGATE CRUSHING VALUE. Aggregate crushing value is an indicator of the crushing resistance of the aggregates when a compressive load is increased. It is tested in accordance with BS 812:110, 1990 and aggregate passing a 14mm test sieve and retained on 10mm sieve are considered for the testing. The allowable range is 17- 41.

A stone crushing plant is primarily involved in the manufacture of aggregates of various sizes (coarse aggregates, crusher run, rock sand and other fine aggregates) from basalt boulders. Coarse aggregates are usually used in ready mix concrete and asphaltic concrete. Crusher run is used for the bases and sub-bases for road making.
