Gyratory crusher copper bushings include:

　　Upper and lower friction discs, frame bushings, eccentric copper bushings, thrust bearings, copper slip rings.

Upper Bronze Plate

　　The upper bronze plate of the spindle assembly, located above the centre steel plate, is a wear part.

　　Lower Bronze Plate

　　The lower bronze plate of the piston assembly, located below the centre steel plate, is a vulnerable part.

 The material is mostly aluminium bronze with high hardness and good mechanical properties, which is processed through the metal casting process.

　　Frame Bushings

　　Also known as the outer bronze bushing, spindle bushing, copper bushing, the material is mostly used in high lead bronze, the material is mostly used

  in high lead bronze, the material is mostly used in high lead bronze.

　　Eccentric Bushings

　　Also known as eccentric bushing, drive gear shaft bronze bushing, inner bronze bushing, etc. The material is high-lead bronze.

　　Thrust bearing

　　Also known as the lower thrust bearing disc, pressure ring, etc., the role is to reduce wear and tear of parts, fixed, to protect the mechanical parts. 

The material is mostly made of aluminium bronze with high hardness and good mechanical properties, which is processed by centrifugal casting technology.
