Cone crushers were originally designed and developed by around 1920 and therefore are often described as cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory crushers.

Crushed stone: If you hear the generic “crushed stone” term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

Compression strength test of stone is determined in this type of test. Procedure: The sample taken for the test should be a cube of size 40mm×40mm×40mm or 50mm×50mm×50mm. The sides of the cubes are made smooth by dressing and polishing. The test should be carried out on dry as well as on saturated samples.

Stone Processing activities include conveying, screening, secondary and tertiary crushing, and sizing. Screening is the single most important part of the processing cycle of crushed stone particles. A wide variety of screen types exist, and their selection is a function of the material processed and the final product required.
