Jaw crusher and cone crusher are two common crushing equipments, which have significant differences in structure, working principle, application scenarios, etc. The following is the main comparison between the two:
1. Structure and appearance
Jaw crusher:
Simple structure, mainly composed of frame, movable jaw, fixed jaw, eccentric shaft, flywheel, etc.
The appearance is rectangular, and the feed port is large.
Cone crusher:
Complex structure, composed of frame, movable cone, fixed cone, eccentric sleeve, hydraulic system, etc.
The appearance is conical, and the overall structure is relatively compact.
2. Working principle
Jaw crusher:
The material is crushed by the periodic extrusion movement of the movable jaw and the fixed jaw.
The movable jaw moves back and forth, and the material is squeezed and sheared in the crushing chamber.
Cone crusher:
The movable cone is driven by the eccentric sleeve to make a swiveling motion, and the material is squeezed, bent and sheared in the crushing chamber.
The motion trajectory of the movable cone is swiveling, and the crushing process is more continuous.
3. Crushing method
Jaw crusher:
Mainly uses extrusion crushing, suitable for coarse and medium crushing.
The crushing ratio is relatively small (usually 4-6).
Cone crusher:
Mainly uses extrusion, bending and shearing crushing, suitable for medium and fine crushing.
The crushing ratio is larger (usually 5-8), and the discharge particle size is more uniform.
4. Discharge particle size
Jaw crusher:
The discharge particle size is coarse, usually between 10-350mm.
Suitable for coarse crushing operations with low particle size requirements.
Cone crusher:
The discharge particle size is fine, usually between 5-60mm.
Suitable for medium and fine crushing operations with high particle size requirements.
5. Processing capacity
Jaw crusher:
The processing capacity is low, suitable for small and medium-sized production lines.
Suitable for processing materials with higher hardness.
Cone crusher:
The processing capacity is high, suitable for medium and large production lines.
Suitable for processing materials with medium hardness.
6. Energy consumption and efficiency
Jaw crusher:
Low energy consumption, but relatively low efficiency.
Suitable for intermittent operation.
Cone crusher:
High energy consumption, but higher efficiency.
Suitable for continuous operation.
7. Application scenarios
Jaw crusher:
Mainly used for coarse crushing in mining, construction, metallurgy and other fields.
Suitable for processing large pieces of materials.
Cone crusher:
Mainly used for medium and fine crushing in mining, building materials, chemical industry and other fields.
Suitable for processing medium-sized materials.
8. Maintenance and cost
Jaw crusher:
Simple structure and low maintenance cost.
Conveying parts (such as jaw plates) are easy to replace.
Cone crusher:
Complex structure and high maintenance cost.
Conveying parts (such as liner plates) are more complicated to replace, but have a longer service life.
9. Comparison of advantages and disadvantages
Features Jaw crusher Cone crusher
Advantages Simple structure, low cost, suitable for coarse crushing High efficiency, uniform particle size, suitable for medium and fine crushing
Disadvantages Uneven discharge particle size, low processing capacity Complex structure, high cost, difficult maintenance
Summary
Jaw crusher is more suitable for coarse crushing, especially for large and hard materials, with low cost and easy maintenance.
Cone crusher is more suitable for medium and fine crushing, especially for scenes with high requirements for discharge particle size, with high efficiency but high cost.
Which equipment to choose depends on specific production needs, material characteristics and budget. In actual production, the two are often used together, with jaw crusher for coarse crushing and cone crusher for medium and fine crushing.
