The crushing process is commonly conducted in several stages. Each stage of the crushing process implements a different type of crusher to gradually reduce the size of the material. The first step is crushing the material by using larger crushers that can reduce the material into smaller sizes that will be used in the next stage.

2.2. Samples analysis after comminution2.2.1. Particle size distribution. The gold ore sample of 200 kg was first fed to the primary crusher (PEX-150 × 250 mm) and secondary crusher (XPC-60 × 100 mm) to ensure all the sample could pass through a sieve of 20 mm.The comminuted ore was then thoroughly mixed and divided, fed to the …

A cone crusher can crush a variety of rocks, from medium to hard. The way a cone crusher operates is similar to how a gyratory crusher does, but in a cone crusher the slope in the breaking space is not as steep. Although it is known for its ability to crush hard and abrasive ores and rocks, the cone crusher is better suited for secondary crushing.

The size characteristics of the feed are important consid- erations. The coarser the feed, the larger the number of crushing stages and degree of compaction the feed has to undergo before it is discharged. It is commonly observed that the degree of compaction of the product decreases with increasing coarseness of the feed.
