Crusher is a mechanical equipment that uses external force to break large solid materials into small pieces or powdery materials. It can be widely used in mining, metallurgy, chemical industry, building materials, coal, refractory materials, ceramics and other industrial sectors.
Application of crusher in construction industry
In the construction industry, crushers can process construction waste, such as concrete blocks, bricks, asphalt, etc., and crush them into reusable aggregates and smaller particles for the production of new building materials, such as recycled concrete, road base materials, etc. This not only reduces the impact of construction waste on the environment, but also reduces construction costs.
5 major applications of crushers in construction
| The Core Function Of Crushers In Construction |
| Crushing hard materials |
such as rocks, concrete, stone, etc. |
| Generating construction aggregates |
producing sand and gravel for concrete, mortar and asphalt. |
| Recycling construction waste |
crushing and screening construction waste such as abandoned concrete, bricks, tiles, asphalt, etc., and converting them into recycled aggregates to reduce resource waste and environmental pollution. |
| Raw material crushing and aggregate production |
crushing raw materials such as natural rocks, ores or construction waste into aggregates (sand, gravel) that meet engineering requirements for the production of building materials such as concrete, mortar, and asphalt. |
| Aggregate quality optimization |
adjusting the physical properties of aggregates (such as particle shape, grading, and crushing value) through crushing processes to meet the needs of different construction projects. Impact crushers produce machine-made sand with fewer edges and corners to improve the workability of concrete. Cone crushers perform secondary crushing to eliminate needle-like particles. |
What crusher can be used in construction?
Common crusher types and applicable scenarios in construction
1. Jaw Crusher
Jaw Crusher is mainly composed of two jaw plates, the movable jaw and the static jaw, to form a crushing chamber, simulating the movement of the two jaws of animals to complete material crushing. It has a simple structure and low cost, and is suitable for coarse crushing. The jaw crusher has a large crushing ratio (3:1~6:1) and can handle materials with high hardness (such as granite and basalt).
| Application construction scenarios |
suitable for mining and preliminary treatment of construction waste. |
| Applicable materials |
rock, concrete block, sintered brick, etc. |
2. Cone Crusher
Cone Crusher consists of a frame, a fixed cone, a movable cone, an eccentric sleeve, a spring and other components. The movable cone performs a rotary swing motion under the action of the eccentric sleeve and forms a crushing chamber with the fixed cone. Efficient fine crushing, high degree of automation, suitable for medium and fine crushing.
| Application construction scenarios: |
Secondary/tertiary crushing: production of machine-made sand and gravel (particle size ≤5mm). |
| Applicable materials |
medium hardness rock (limestone, sandstone). |
3. Impact Crusher
The impact crusher consists of a rotor, an impact plate, a plate hammer and other components. The rotor is equipped with a plate hammer. After the material enters the crushing chamber, it is impacted by the plate hammer and the impact of the impact plate and crushed. High crushing efficiency, the finished particles are cubic and have no internal cracks.
| Application scenario |
fine crushing, production of high-grade concrete aggregate (such as C50 and above). |
| Applicable materials |
suitable for materials with medium hardness or below (such as coal gangue, gypsum). |
4. Mobile Crusher
The mobile crusher is a crushing equipment that integrates feeding, crushing, screening and conveying. Mobile Crusher can easily perform crushing operations at different locations. The movable chassis can flexibly adapt to the construction site environment.
Application scenario: on-site treatment of construction waste.
