CHANGSHA TIGER MACHINERY CO., LTD.

Your Technical Partner in Crusher Components

CHANGSHA TIGER MACHINERY CO., LTD. specializes in crusher wear parts and spare components backed by deep technical expertise. We don't just supply parts — we provide detailed specifications, material data, and application guidance to help you make informed purchasing decisions.

What Sets Us Apart

Model-Level Precision: Unlike general parts catalogs, we maintain individual technical pages for each crusher model — from Metso C63 to C200, HP100 to HP800, Sandvik CH420 to CH890, and beyond. Every part number, material grade, and dimension is documented.

Materials Science Focus: We publish comprehensive alloy reference data — DIN, SAE, GB/T copper alloy standards, metal density charts, and casting process comparisons — because understanding the metallurgy behind the part matters.

Multi-Process Manufacturing: Our supply chain spans centrifugal casting for bronze bushings, sand casting for manganese wear parts, forging for shafts and gears, and precision CNC machining — giving you single-source access to every crusher component type.

Global Reach

From our base in Changsha, China, we serve mining and quarry operations worldwide. Our technical documentation and responsive support ensure you get the right part, the first time.
