In the sand aggregate production line, jaw crusher (jaw break) and cone crusher (cone break) have significant advantages over hammer crusher (hammer break), which makes them more favored in practical applications. The following is an analysis of the advantages of jaw break and cone break over hammer break:
1. Crushing efficiency and grain type
Jaw breaking: deep cavity crushing design, no dead zone, large crushing ratio, uniform product particle size, and the discharge can be flexibly adjusted by adjusting device.
Cone breaking: The use of laminated crushing principle, high crushing efficiency, the finished grain shape is good, mostly cube structure, suitable for high-quality sand aggregate production.
Hammer breakage: although the crushing ratio is large, the finished particle shape is poor, it is easy to produce over-crushing phenomenon, and there are more needle flake materials, which affects the quality of aggregate.
2. Applicable materials and wear resistance
Jaw breaking: suitable for materials of various hardness, strong wear resistance, can effectively break large pieces of stone, reduce equipment wear.
Cone breaking: Especially suitable for medium hard to high hard materials (such as granite, basalt) in the crushed and fine, wear parts long life, low operating costs.
Hammer break: poor adaptability to material hardness, serious wear when dealing with high hardness materials, high frequency of replacement hammer head.
3. Equipment stability and maintenance
Broken jaw: simple structure, easy operation, low maintenance cost, long service life.
Cone break: Equipped with hydraulic protection and automatic control system, can automatically clear the cavity and adjust the discharge port, reduce downtime, easy maintenance.
Hammer: The stability of the equipment is poor, there are many wearing parts, the maintenance cost is high, and manual intervention is required when the overload occurs.
4. Energy consumption and environmental protection
Broken jaw: relatively low energy consumption, suitable for coarse crushing operation.
Cone breaking: low unit power consumption, high crushing efficiency, and good environmental performance.
Hammer breaking: high energy consumption, and the dust in the crushing process is large, and the environmental protection is poor.
5. Application Scenarios
Jaw breaking: widely used in mining, construction, chemical industry and other industries of the initial breaking operation.
Cone break: mainly used for medium and fine crushing, suitable for high-quality sand aggregate production line.
Hammer breaking: It is mostly used for the crushing of soft materials such as limestone, but it is less used in the sand aggregate line.
Sum up
Jaw breakage and cone breakage have significant advantages in sand aggregate production line. Jaw breaking is suitable for coarse crushing, strong crushing ability, low maintenance cost; Cone breakage is excellent in medium and fine crushing, and the finished grain shape is good and the wear resistance is high. In contrast, although the crushing ratio is large, there are obvious deficiencies in particle shape, wear resistance and maintenance cost, so it is less used in the aggregate line of sand and stone.
