Concrete refers to a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to cement used as cementing material, sand and stone as aggregate, mixed with water (containing additives and admixtures) in a certain proportion, and the cement concrete obtained by stirring is also called ordinary concrete, it is widely used in civil engineering. The demolished concrete block is a kind of construction waste. It generally contains materials such as steel bars, wood, and rags. After being crushed, it can be turned into gravel aggregate for road construction, houses, etc. So, how to deal with concrete, and effectively remove materials such as steel bars, wood, rags, etc. This is the problem that most of us are now concerned about how to choose a crusher and what is the budget?
Concrete blocks are generally about 50cm large and about 5cm small. Generally, the crushing process uses two types of fixed crusher or mobile crusher. If the customer requires strong flexibility and the space is not limited, it is more appropriate to choose a mobile breaker; if the customer only requires low cost and the site does not require it, then use fixed crusher equipment.
Fixed crusher
Category: DHKS series jaw crusher, 2PGC series construction garbage crusher, ZSW series vibrating feeder, YKR series circular vibrating screen, PFQ series impact crusher
Output: 100t/h
Finished products: 0-5mm, 5-10mm, 10-20mm, 20-31.5mm aggregates; recyclable metals, etc.;
Final products: recycled block bricks, permeable concrete, etc.
Equipment characteristics: relatively low investment cost, large output and large crushing ratio, suitable for fixed operation site.
Production process: The raw materials after pretreatment are sent into the large silo by forklift or hook machine. The vibratory screening feeder (ZSW series) will separate gypsum, soil and small concrete blocks (less than 120mm) while ensuring uniform feeding to the crusher. Large materials (more than 120mm) enter the jaw crusher (DHKS3624) for primary crushing, and fall into the vibration feeder (ZG200) after buffer adjustment (the role of the vibration feeder is to protect the belt to prevent the belt from being scratched by thick steel bars) Injury), enter the secondary crushing through the belt conveyor. The secondary crushing adopts the construction waste special crusher (P2PGC series construction waste crusher), which has the dual functions of screening and crushing, high crushing efficiency, and the special cavity type is not afraid of steel bar winding. The materials are crushed into materials smaller than 50mm by the impact crusher (PFQ series), and most of the steel and concrete are separated, and then conveyed to the screening system through the belt (the screening system includes two parts: soil removal screening and material classification) for processing.
Mobile crushing plant
Category: Tire Mobile Crusher, Crawler Mobile Crusher
Output: 50-500t/h
Equipment features: intelligent control, flexible and convenient, high degree of automation, environmental protection and energy saving, suitable for scattered users on the job site, and high investment cost.
Both fixed and mobile crushers can crush concrete blocks for processing. Choose the quality of the crusher, and compare the advantages and disadvantages of the equipment. Both fixed and mobile breaks have their own characteristics and advantages. If you want to do engineering, there are more venues. You can choose to move the crushing station, although the initial cost investment is more, but the payback later is also faster. Not subject to regional restrictions, multiple sites work back and forth, and operation labor costs are also low. If you own a construction site and the production is relatively fixed, you can choose a fixed crusher, and the overall cost is more suitable.
