How to Select a Rock Crusher According to Crushing Method

Rock crusher is a general term for types of crushes, which is widely used in smelting, building construction, road construction, mineral mining, water conservancy and chemical industry, etc. At present, the most frequently used rock crushers are the jaw crusher, cone crusher, impact crusher, hammer crusher, combination crusher, sand crusher and roll crusher. Due to the particle shape of the material is irregular and material property is different, so the crushing method of crusher machine is also different, mainly divided into five types: squash crushing, spilled crushing, fold crushing, impact crushing and scrunch crushing.

A. Squash crushing: The extrusion pressure of the rock crusher's two crushing working faces is used to crush the material.

B. Split crushing: The rock crusher utilizes the splitting force of the sharp teeth wedging material to finish the crushing operation.

C. Fold crushing: Material is subjected to a concentrated load like the two fulcrums or multi-fulcrum beam in the crushing work face, when the bending stress oversteps the acceptable bending strength of the material, the material is broken off.

D. Impact crushing: The rock crusher makes use of the impact force from its hammerhead to crush the material, and its impact force is the instantaneous force acting on the material.

E. Scrunch crushing: The two crushing working surfaces of rock crusher make the relative motion on material, and apply the shearing force to material, when the shearing force reaches the shear strength limit of material, the material will be broken.

Each crusher machine is divided into different types and models according to the specific production requirement. Before the customer purchases the rock crusher, first of all, he should determine the crushing way according to the material property and his own granularity requirement for the material, then determine the corresponding types of crushes and crusher machine model. It is mainly divided into the following situations:

A. The large or medium sized hard materials are usually crushed by the squash crushing or impact crushing way, such as the jaw crusher, toothed roll crusher, etc.

B. Strong-corrosivity materials are generally handled by the squash crushing method, the crushing surface of available rock crusher should be smooth.

C. Weakly corrosive materials can be processed in the impact crushing, scrunch crushing or squash crushing way, the crushing surface of available crusher machine should be with the sharp teeth.

D. The small hard materials are usually crushed by the squash crushing, impact crushing or scrunch crushing method, the rock crusher surface should be smooth without the tooth seam, such as the double roll crusher.

E. Materials with strong toughness are generally processed in the scrunch crushing or impact crushing way, such as the hammer crusher.

F.Powdery or muddy materials should be ground, impact crushed or squash crushed, such as ball mill.

G. Multi-component materials can be handled by the impact crushing way or in combination of various force fields.
