Cone Crusher Liners Procurement Guide | HUATAO Group
1. Definition
Cone crusher liners are consumable wear parts installed inside a cone crusher. They consist of the mantle (mounted on the main shaft) and concave (mounted in the crusher frame). The gap between these components forms the crushing chamber where material is crushed.
The quality of Crusher Wear Parts directly affects crusher performance, product shape, throughput, and operating costs.
The cone crusher operates in the Crushing stage of the mineral processing flow. After primary crushing by a Jaw Crusher, secondary and tertiary cone crushers reduce material before feeding into the Screening stage via Vibrating Screen Panels.
2. Working Principle
Cone crusher liners work through compression and gyratory motion:
Step 1: Feed material enters through the feed cone
Step 2: The mantle gyrates eccentrically within the concave
Step 3: Material is crushed in the gap between mantle and concave
Step 4: High manganese steel work-hardens under impact (200-220 HB → 450-600 HB)
Step 5: Crushed material exits through the bottom opening
