1. Application of PYB/PYZ/PYD cone crusher

Cone crusher is a kind of crushing machine commonly used in mining, metallurgical industry, construction, road construction and chemical industry. Our cone crusher can be used to crush hard and medium hard minerals, rocks, iron ores, limestone, copper ores, quartz, granite, sandstones, etc. In a whole production line, usually, the cone crusher is used for secondary or tertiary crushing process, or first crushing.

 

2. Special advantages of DongMeng PY series cone crusher

A). Reliable quality approved by CE and reach to European quality standard.

B). Grease seal can effectively avoid the blockage of water feeding system and drainage system, as well as mixing of water and oil.

C). Large and medium-sized crushers adopt hydraulic chamber-cleaning systems, which will help reduce the down time

D). Cone crushers with different chambers are available, to meet our customers' requirements.

E). As the overload protection device, spring safety device allows foreign matter and iron pieces to pass through the crushing chamber without jeopardizing machines.

F). In normal condition, the operation rate of trouble free is more than 95%.

 

3. Working principle of PY series cone crusher

A). When cone crusher is working, motor drives the eccentric sleeve to rotate. The eccentric sleeve drives the transmission shaft and cone part to make swing movement. When they swing to the extent that the surface of the crushing wall is close to the roll mortar wall, the rocks and ores are pressed and crushed.
B). Joint between supporting sleeve and frame is compressed by spring. When metal block and other materials that can no be crushed fall into the crusher, spring will be out of sharp and discharge the objects.
C). When the materials that can not be crushed pass through the crushing chamber or the machine overloads, the spring safety system makes the cone discharging hole become larger. When objects are discharged from crushing chamber, discharging hole will automatically reset. Cone crusher resumes normal operations.
D). The surface of crushing chamber is covered with wear-resisting high manganese steel lining plate. Size of discharging hole can be adjusted hydraulically or manually.

 

4. General description of PY cone crusher:

  DongMeng PY series cone crusher get to world advanced level. We combine high-efficiency crushing chamber with high crushing frequency, in order to increase capacity. Furthermore, finished products are cubic-shaped and less needle-flake materials, owing to the technology of laminated crushing.
