Py series spring cone crushers are widely used in metallurgical industry, construction industry, road construction industry, chemical industry and phosphate industry. They are suitable for crushing hard and medium hard ores and rocks, such as iron ore, copper ore, limestone, quartz, granite, basalt, diabase, etc. The type of crushing chamber is determined by the ore use: the standard type is suitable for medium crushing, the medium type is suitable for fine crushing, and the short head type is suitable for ultra-fine crushing.

1. Reliable operation of special seal: the spring cone crusher adopts two sealing methods of dry oil or water, so that dust and impurities cannot enter the machine body, so as to ensure the cleanness of lubricating oil, prolong the service life of sliding bearing and thrust ball bearing, and make the machine operate reliably.

2. High production efficiency, good product particle shape: the moving cone rotates continuously, and the crushing and unloading are carried out alternately and continuously along the working surface, with high productivity; A parallel belt is set between the moving cone and the fixed cone to ensure uniform particle size of finished materials.

3. Low energy consumption and less wear: because the material is sandwiched between the two cones and subjected to extrusion, bending and shear, it is easy to break and low power consumption; The product has uniform particle size, uniform wear on the working surface of the moving cone and low loss.

4. Simple maintenance of overload protection: the spring safety system is an overload protection device, which can make metal foreign matters pass through the crushing chamber without endangering the machine; At the same time, the machine is easy to disassemble and repair, which greatly reduces the shutdown and maintenance time.

When py series spring cone crusher works, the motor drives the large bevel gear at the bottom of the eccentric sleeve through the hydraulic coupling and small bevel gear to rotate the eccentric sleeve, causing the cone to swing and crush materials. The main shaft of the crusher does not move, but only supports the duster spherical tile to bear the crushing force. Because the main shaft of the crusher does not move and the eccentric sleeve transmits the crushing force, the structure can bear large crushing force and is very suitable for fine crushing and ultra-fine crushing, because the crushing force of ultra-fine crushing is very large.

The working part of Py series spring cone crusher is two truncated cones, one is fixed cone (also known as outer cone) and the other is moving cone (also known as inner cone). The fixed cone is stationary and a part of the frame. The moving cone is hinged at point O, and its lower end is movably inserted into the eccentric bushing. Therefore, the central axis OO 'of the fixed cone intersects with the central axis oo1 of the moving cone into an oblique angle. When oo1 rotates around OO ', the moving cone makes a partial rotation movement along the inner surface of the fixed cone. In the section where the moving cone approaches the fixed cone, the material is squeezed, impacted and bent by the moving cone to become a crushing chamber; At the place where the moving cone deviates from the fixed cone, the crushed materials are discharged from the cone bottom under the action of self weight to become the discharge port, and the materials are loaded from the feed port.
