Crusher, also known as stone crusher, is a kind of mechanical equipment widely used in mining, building materials, roads, railways, water conservancy and other fields. Its main function is to break large pieces of materials (such as rocks, ores, concrete, etc.) into small particles by mechanical force to meet the production needs of different industries.
The working principle of crusher usually involves the feeding, crushing and discharging process of materials. The material enters the crushing chamber of the crusher through the feed port, and is subjected to the force of the crusher (such as rotating blades, hammers, cones, etc.) in the crushing chamber, and experiences the effects of impact, extrusion and shearing, so that it breaks and breaks. The crushed material is separated into particles of different sizes through the screen and finally discharged from the discharge port.
According to the different working principles and uses of crushers, they can be divided into many types, such as hammer crusher, jaw crusher, cone crusher, etc. Each type of crusher has its unique working principle and scope of application, and users can choose the appropriate crusher according to their needs.
In summary, crusher is an important mechanical equipment, which provides strong support for the production of various industries through its efficient crushing capacity.

The above data is based on a feed with a density of 1.6t/m³and a moderate particle size that can smoothly enter the crushing chamber.The processing capacity is the instantaneous maximum processing capacity and varies according to the material properties:feed gradation,feed moisture and clay content,bulk density and cleavage characteristics.When the jaw plate is a sharp tooth,the discharge opening is the distance from the bottom of the tooth tip to the top of the other jaw plate tooth tip;when the jaw plate is a flat tooth,the discharge opening is the minimum distance between the outer tooth tops of the jaw plate.
