Zhengzhou Hongxing Machinery Cone Crushers have been widely used in mines and quarries around the world for more than 30 years. Zhengzhou Hongxing Machinery makes four main types of cone crushers: the ROC/C Standard for coarse crushing, the ROC/F for fine or medium uses, the ROC/S Short Head and the ROC/SS Super Fine. These four crusher types are designed for secondary or tertiary crushing of highly abrasive materials in ether fixed or mobile plants.
Simplicity of design and rugged construction make Zhengzhou Hongxing Machinery Cone Crushers ideal for any crushing operation. Users could choose from a wide range of Cone Crusher models for optimal yield and cost-effective production. Zhengzhou Hongxing Machinery Cone Crushers are known for their rugged construction.
The Zhengzhou Hongxing Machinery standard Cone Crusher is normally applied as a secondary crusher in plants designed for three or four stages of crushing. However, the wide range of crushing cavities available in the Standard Cone Crusher permits its installation as a primary crusher in many cases.
Working principle of Cone Crusher
In a Cone Crusher the rock material is crushed between rigid surfaces. The motion of the moving surface is independent of the loading of the crusher, therefore the explored combination principle is‘form-conditioned’compressive crushing. The crushing action is achieved by an eccentric gyratory movement of the main shaft axis, as shown in figure 1. Particles are nipped, compressed and crushed between the mantle and the concave. Breakage of particles can be both single particle (particles are broken between cone and mantle) and antiparticle (between other particles). The mantle and the concave must be replaced regularly as they are subjected to continuous wear.
Crushing takes place continuously and is antiparticle to a great extent. Antiparticle crushing is achieved when a particle is stressed and broken between other particles. This type of breakage is desirable from the point of view of wear and service life, and is also considered to give the best particle shape. To achieve antiparticle breakage choke-fed conditions are normally recommended. Choke-fed conditions imply that the inlet of the crusher is covered with feed material, which is then fed into the crusher under the influence of gravity. The distance between the mantle and the concave at the outlet of the crushing chamber is called the closed-side setting when the mantle is in its closed position.
