PYB/PYZ spring cone crusher

PYB spring cone crusher is a kind of cone crusher which is manufactured in the former Soviet Union; it combines 1980s international technology and kinds of cone crushers’ technology. One the basis of these technologies, Tarzan had successfully developed the compound cone crushers, hydraulic cone crushers by our efforts. The spring safety device is the overload protection device which can avoid the damage to the machine when metallic foreign body entre through the crushing cavity. The capacity of this machine is very big, owning to the technology of laminated crushing, finished products are mainly cubic shape and less needle-flake material. It is widely used in industries of metallurgy, architecture, road construction, chemical industry, phosphate. It is the preferred choice for secondary crushing equipment which is used for hard and medium mineral rock such as iron ore, copper ore, limestone, quartz, granite, basalt and dolerite.

Feature:
1. The moving cone of this machine rotates continuously, the process of material crushing and products discharge carry out alternatively and continuously along the work surface, thus the product efficiency improved a lot by this solution. There is a equally parallel gap between the moving cone and the fixed cone, so the grain size of finished products are uniform.
2. Longer using life, reliable operation
Two kinds of sealing: dry oil or water makes sure that the dust can’t enter the body. This solution can guarantee the cleanness of lubricating oil, extend the life of spherical bearings, and make the machine operate reliably.
3. Low operating cost, wide field of application
Due to large capacity, high reliability, easy maintenance, this machine can reduce the production cost heavily. It promotes the cone crusher to achieve greatest performance. It is applied for kinds of crushing technics: primary crushing to fine crushing; stationary crushing plant to mobile crushing plant.
 
Principle:
When the spring cone crusher works, the motor drives the eccentric sleeve to rotate by horizontal axis and a couple of bevel gear. Under the rotation of eccentric sleeve, the crushing cone axis line swings, thus makes the broken wall surface come or leave the rolling wall surface from time to time. This movement leads the ore to be pressed, bended and at last to be crushed in the cavity.
