The principle of how an impact crusher works is to impact and try to explode material. When steel, wire, and/or rebar are fed into an impact crusher, the machine could be damaged or wear out significantly faster than a jaw. The jaw crusher operates at slower speeds and tries to compress and compact material rather than explode it.

Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).

An impact crusher consists of several components, including the rotor, hammers, impact aprons, and screens. The rotor is the central part of the machine, and it is the part that rotates and drives the hammers. The hammers are attached to the rotor by means of a pivot point, which allows them to move freely and strike the material with …

Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in large-scale industries for crushing various types of materials into smaller sizes.

The primary crusher's function is to reduce the size of the rock or stone for easier handling and transportation. The primary crusher is usually a jaw crusher or a gyratory crusher, which operates by compressing the material between two surfaces. The jaw crusher works by moving the material between a fixed and a moving plate.

The keys are to find the biggest fenner pulley you can find (and afford) for the spindle on the crusher, the smallest pulley you can fit on the motor and a motor that goes 1100 rpm or less. The rest of the work is just building a mounting bracket. I suggest making the motor removable which makes the crusher light enough for one person to carry.

Closed Circuit is defi ned as a combination of a crusher and one or more screens were all or parts of the material will pass the crusher. Over sized material will then be re-circulated to somewhere before the crusher and thereby fed to the crusher again to be re-crushed. Parts of the rock material will thereby pass the crusher more then once.
