EC Extra Coarse
Structural Features: Largest feed opening, steepest crushing chamber, highest upper limit of crushing ratio
Applicable Working Conditions: Processing large, hard materials; primary crushing in mines; pre-processing of primary medium crushing
Selection Goal: Maximize feed size, achieve ultra-high crushing ratio; primarily for coarse processing of large hard rock
C Coarse
Structural Features: Standard medium crushing coarse chamber; optimal balance between processing capacity and particle shape
Applicable Working Conditions: Various metal/non-metal mines; mainstream medium crushing operations for sand and gravel aggregates
Selection Goal: General medium crushing scenarios, balancing capacity and basic particle shape control
M Medium
Structural Features: Most versatile across the entire series; outstanding lamination crushing effect; significant improvement in the needle-like and flaky shape of finished products
Applicable Working Conditions: High-quality sand and gravel aggregate production; mid-range stone shaping
Selection Goal: Significantly optimize the particle shape of finished aggregates while ensuring high output
F Fine Cavity Type
Structural Features: Reduced crushing chamber steepness, longer parallel zone, more material crushing cycles
Applicable Working Conditions: Secondary fine crushing, high-quality aggregate processing
Selection Goal: Producing uniform finished material with finer particle size and higher cubic content
Extra Fine Cavity Type (EF)
Structural Features: Longest parallel zone, compact crushing chamber, highest crushing frequency
Applicable Working Conditions: Ultra-fine aggregate, pre-sanding fine crushing, demanding fine material production scenarios
Selection Goal: Specifically for producing ultra-fine aggregate, high-fineness crushing operations
Single-Cylinder Cone Liner Selection Logic
- Large feed block, coarse crushing open-circuit production → EC Extra Coarse / C Coarse Cavity
- Conventional mines, general medium crushing for sand and gravel, balancing output and particle shape → M Medium
- Requires high-quality aggregate, reducing needle-like and flaky particles → F Fine Cavity
- Producing ultra-fine aggregate, pre-sanding fine crushing → EF Extra Fine
