Stone Crusher is a component of the rock-breaking equipment that serves to break down and reduce the size of material (stone). Generally composed of primary rock-breaking equipment depending on the combination of aggregate. In general, consist of primary crusher and jaw crusher types, gyrator crushers, impactors, or a single roll crusher is capable of reducing the size of large size stone (ma ks. 91.44 s / d 121.92 cm).
Breaking stones to stone the size of a small / more can use twin or triple roll crusher, cone crusher, or a hammer mill.
Primary Stone Crusher is the first step is crushing, crusher equipment normally used at this stage is Gyrator Crusher and Jaw Crusher. Bait used is usually derived from the mining results with the sizes ranging from 1500 mm, with the size settings between 30 mm to 100 mm. The largest size of the first stage of crushing products are usually less than 200 mm.
Secondary Stone Crusher is the second stage of crushing, crusher tool used is Cone Crusher, Hammer Mill and Rolls. Bait is used ranges from 150 mm, with a size between 12.5 mm to 25.4 mm. Produced the largest product is 75 m. Fine crushing, crushing an advanced stage of secondary crushing, the tool used is the Rolls, Dry Ball Mills, Mills Disc Mills. Bait is typically used less than 25.4 mm. to minimize the material mined is still commonly used sized lump crusher tool. Material results from the crushing and then do the sifting or screening that will produce two kinds of products are products which qualify for the so-called sieve undersize which is a product that will be further processed or as a final product, and materials that do not qualify for the so-called over sized sieve which is a product that must be Crushing done again.
