PYB/PYD/PYZ concave and mantles for cone crusher Cone crusher wear resistant mantle, concave, bowl liner Main material is high manganese steel,  Mn 13%, Mn 18%   Our advantage:  1. 30 years experience on technique 2. High wear-resistance feature,long life time 3. In time service feedback 4. One-stop solution available 5. OEM service available   Main casting process: Lost foam casting, The process way could save more cost than others,  The casting parts face is better than others.    Meanwhile, we also provide customised materials to our customers. B.Manufacturing Processes  photos of  concave and mantle:   Suitable equipment:Cone crusher   Cone crusher rolling mortar wall, crushing wall provided by YK are widely used for crushing iron ore, non-ferrous metal ores, granite, limestone, quartzite, sandstone, pebbles and so on. Products using modified high manganese steel, after modification treatment, combined with advanced production technology, manufacturing, so the service life increased by 30-50% than traditional materials, and also with impact, friction, compression, shear, and long service life characteristics.     Operating Principle:   During operation, the motor drives the eccentric shaft shells to turn around through a horizontal axle and a pair of bevel gear. The axle of crushing cone swings with the force of eccentric shaft shell so that the surface of the crusing wall is close to the roll mortar wall from time to time. In this way, the ores and rocks will be pressed and crooked and crushed.    Applicational Area:   Cone crusher is widely applied in mining, metallurgy, construction, road building, chemical and phosphatic industry, and is suitable for hard and mid-hard rocks and ores.    Our Advantages and Features:   1. Abundant technology, advanced production, sophisticated processing equipment and completed  inspection facility.   2. Every process being controlled and every machine and spare parts being inspected.   3. We will provide with one-stop services, real-time tracking and co-operation you.   4. Authorized by the National ISO9001 quality system.   5. Japan Advanced LOBF Direct-reading Spectrometer   6. Tensile Strength: 190-220MPa   7. Brinell hardness: 500-540 HB    The cone crusher spare parts we supply:concave,mantle, bowl liner, bowl shaped bearing, eccentric shaft bushing,spring,bolt,nuts
