There are significant differences between jaw crushers and cone crushers in many aspects. The following are the main differences between them:
1. Structure and working principle:
• Jaw crusher is mainly composed of a frame, movable jaw, fixed jaw, lining plate, screen plate, adjustment device, and other components. Its working principle is to use two jaw plates (one fixed and one movable) to exert pressure on the material so that the material is crushed, bent, and split between the jaw plates.
• The cone crusher is mainly composed of a frame, a moving cone, a fixed cone, a lining plate, a screen plate, an adjustment device, and an eccentric sleeve. Its working principle is that the electric motor drives the eccentric sleeve to drive the movable cone to perform a swing motion, and the materials are continuously impacted, squeezed, and bent in the crushing chamber to be broken.
2. Crushing stage and material adaptability:
• Jaw crusher is often used in the primary crushing stage of the production line, that is, the coarse crushing link. It is suitable for processing materials of various hardnesses, including materials with compressive strength between 200-1200MPa. The jaw crusher has no strict restrictions on the particle size of materials and can crush materials with a side length of no more than 500mm.
• Cone crushers are more suitable for the secondary and fine crushing stages. It mainly handles materials with medium hardness and above and has a strong crushing capacity and high material utilization rate. The feed particle size of the cone crusher can usually reach 500mm, and the output range is wide (12-2000t/h).
3. Performance characteristics:
• Jaw crusher has the advantages of simple structure, easy manufacturing, reliable operation, and easy maintenance. It has a large crushing ratio and uniform product particle size and is widely used in mining, building materials, highways, railways, and other fields.
• The cone crusher has the characteristics of a large crushing ratio, high efficiency, low energy consumption, and uniform product particle size. It is suitable for crushing hard materials and can control the particle size of the product by adjusting the gap between the movable cone and the fixed cone.
4. Usage scenarios:
• Jaw crushers are commonly used in primary and secondary crushing operations in mining, smelting, building materials, and other industries, as well as in areas such as highways, water conservancy projects, and construction gravel processing.
• Cone crushers are widely used in the crushing of metal mines, construction sand and gravel, glass raw materials, blast furnace slag, steel slag, river pebbles, particularly hard and high-hardness materials, and other fields.
To sum up, there are significant differences between jaw crushers and cone crushers in terms of structure, working principle, crushing stage and material adaptability, performance characteristics, and usage scenarios. When selecting a crusher, it is necessary to comprehensively consider factors such as specific production needs, material characteristics, and crushing stages.
