Cone Crusher Eccentric Bushing Technical Requirement
Material Requirements
Chemical analysis (ladle analysis) ranges (% min./max.) shall be as follows:
| Cu | Sn | Pb | Zn | Fe | Sb | Ni | S | P | Ai | Si |
| 75.00 | 6.30 | 13.00 | / | / | / | / | / | / | / | / |
| 79.00 | 7.50 | 16.00 | 0.80 | 0.15 | 0.80 | 1.00 | 0.08 | 0.05 | 0.005 | 0.005 |
Mechanical Properties
- Tensile Strength Min. PSI (MPa) :24,600
- Yield Strength Mi. PSI (MPa): 11,600
- Elongation In 2 in. (50 mm) Min. % : 8
These properties are per EN 1982 alloy CC496K for sand castings. They are also acceptable for centrifugal and permanent mold castings made to meet this specification.
Quality Standard
Casting sections and surfaces critical for strength and finish shall be free of shrinkage, cracks, porosity, blowholes, hot tears which will be detrimental to use of the finished casting. Runners, risers, fins and other cast-on pieces shall be removed and dressed down to blend with the normal profile of the casting surfaces.
Defect Limitations
Total defects in a casting shall not exceed one percent (1%) of the area of the complete casting surface area. Total defects within any 144 sq. in. (929 sq. cm.) casting surface area shall not exceed two percent (2%) of that area.
Pin Holes (Porosity) – Pin holes less than .063 in. (1.6 mm) diameter do not have to be repaired, unless the area of the perimeter enclosing all pin holes in a surface exceeds one percent (1%) of the total area of that surface, or the defective area will not successfully pass a pressure test, if pressure testing is a requirement. Castings not meeting these requirements shall be subject to the Repair provisions.
Blow Holes – Castings having blow holes with diameters greater than .38 in. (9.6 mm) shall be rejected and be subject to the Repair provisions in Section 8.0 above.The accumulated area of all blowholes on a single (rough or machined) surface of the casting shall not exceed 0.8 percent (0.8%) of that surface area. The maximum number of blowholes permitted within any 144 sq. in. (929 sq. cm) the surface area shall not exceed 20.
Cracks – Cracks on any bearing surfaces or cracks on any surface which will contribute to strength reduction in any section of the casting shall be rejected. Cracks which appear on non-critical surfaces and which are not detrimental to the strength of the casting shall be repaired by welding.
