Bronze bushings and wear parts are irreplaceable core wearing components for cone crushers and gyratory crushers. Their material formula, casting process and precision machining directly determine equipment operation stability, service life and overall crushing efficiency.
High-quality crusher bronze parts strictly follow standardized centrifugal casting production procedures, adopt high-lead tin bronze alloy materials, and cover mainstream single-cylinder, multi-cylinder, Symons and gyratory crusher models. Below we introduce the complete production workflow and full specifications of common crusher bronze components.
Crusher Bronze Parts Manufacturing Production Process
Copper Alloy Melting & Proportioning
Melt and proportion professional copper alloy raw materials, and conduct strict chemical composition inspection to ensure material performance meets industry casting standards.
Casting Mold Preheating
Preheat the casting mold to eliminate internal stress, avoid casting defects, and improve the compactness and uniformity of bronze blanks.
Centrifugal Casting Pouring
Pour molten bronze liquid into the high-speed rotating mold by centrifugal casting technology, forming dense and pore-free bronze bushing blanks.
Cooling & Solidification
Natural and controlled cooling of castings to complete solidification, ensuring stable internal metal structure and mechanical properties.
Precision Machining
Perform turning, boring and fine finishing to achieve strict dimensional tolerance and surface finish requirements.
Inspection & Finishing
Carry out dimensional inspection, appearance detection and flaw inspection, then complete surface finishing and packaging for delivery.
