How to choose the right crusher machine to build an efficient aggregates crushing production line? Jaw crusher, impact crusher or vertical shaft impact crusher? Here, Luoyang Dahua will give you a brief analyse for reference.
- Jaw crusher
Applied field: primary crushing (coarse crusher), for the processing of large block of hard materials (like granite, basalt, iron ore, etc.)
Advantages: simple structure, low maintenance cost | large processing capacity, high compressive strength (up to 320MPa) | large feeding size (1500mm)
Disadvantages: coarse discharging particle size (10-350mm) | poor particle shape (more needle-like and flaky pieces) | high noise and vibration
Recommended application: Coarse crushing in mines and quarries
- Impact crusher
Applied field: medium and fine crushing, for the processing of medium hardness and below materials (like Limestone, concrete, coal gangue).
Advantages: good particle shape (cubic-shape, suitable for construction aggregates) | adjustable feeding granularity (by adjusting the gap between impacting plate and rotor) | large crushing ratio (40:1), less crushing section
Disadvantages: not suitable for high hardness materials (granite), the plate hammer is easy to wear | more powder and noise | high energy consumption
Recommended application: Medium and fine crushing of building materials and construction aggregates, or scenarios where a better particle shape is required.
- Vertical shaft impact crusher (sand making machine)
Applied field: fine crushing and sand making, for the crushing and sand making of hard materials (like pebble, granite).
Advantages: excellent particle shape | fine adjustable of finished products (0-5mm) | with function of crushing and sand making, suitable for stone sand production
Disadvantages: high price, complex maintenance (regularly inspection of rotor and distributor plate) | easy to clog for processing sticky and wet materials | relatively low production capacity, suitable for medium and small scale production line.
Recommended applications: Production of manufactured sand, shaping of aggregates for high-grade highways/railways.
How to choose crusher machine?
- According to the material hardness
Hard rock (such as granite) : jaw crusher (coarse crushing) + cone crusher (medium crushing) + vertical shaft impact crusher (sand making)
Medium soft rock (such as limestone) : jaw crusher (coarse crushing) + impact crusher (medium and fine crushing)
- According to the discharge requirements:
Coarse aggregate (10-50mm) : Jaw crusher or impact crusher
Fine aggregates or manufactured sand (0-5mm) : Impact crusher
- According to the budget:
Low-cost solution: Jaw crusher + impact crusher
High-quality particle shape solution: Jaw crusher + impact crusher
Jaw crusher: A required coarse crushing equipment, suitable for handling large and hard materials.
Impact crusher: High cost performance, suitable for medium and fine crushing and particle shape requirements of medium-hardness materials.
Vertical shaft impact crusher: The preferred choice for sand making and shaping, but it is relatively expensive.
In actual production lines, the three types of equipment are often used in combination (such as jaw crusher for coarse crushing → impact crusher for medium crushing → vertical shaft impact crusher for sand making). It is recommended to make a comprehensive choice based on the material characteristics, production capacity requirements and investment budget.
