The disposal of construction waste involves multiple stages and steps, thus requiring different types of equipment to complete these tasks. Here are some common construction waste treatment equipment:

Crushing equipment:

Fixed crushers, such as jaw crushers, impact crushers, cone crushers, etc., are used to crush construction waste into smaller particles.

Mobile crushing stations: including tire and track types, they integrate functions such as crushing, screening, and conveying, and are suitable for different sites and operational needs.

Screening equipment:

Vibration screen: used for screening construction waste, separating materials of different particle sizes for subsequent processing.

Drum screen: suitable for screening wet and sticky materials, capable of separating soil, stones, etc. from the material.

Sorting equipment:

Wind sorter: separates light substances (such as plastic, paper, etc.) and heavy substances (such as concrete blocks, bricks, etc.) in construction waste through wind power.

Magnetic separator: used to separate iron materials from construction waste.

Conveyor equipment:

Belt conveyor: used to transport construction waste from one place to another, improving processing efficiency.

Bucket elevator: suitable for vertical material conveying.

Dust removal equipment:

Pulse dust collector, bag dust collector, etc.: used to reduce the dust generated during the construction waste treatment process and protect the environment.

Other auxiliary equipment:

Feeder: used to control the speed and quantity of materials entering the crusher.

Dust removal and noise reduction equipment: used to reduce noise and dust pollution.

These devices play important roles in the construction waste treatment process, and through reasonable selection and configuration, efficient and environmentally friendly treatment of construction waste can be achieved. The selection of specific equipment should be comprehensively considered based on factors such as processing scale, material characteristics, and site conditions.

The process of construction waste treatment mainly includes the following stages:

1. Collection and preliminary classification:

Collection: Firstly, collect the garbage generated at the construction or demolition site in a centralized manner to ensure that all types of garbage are not mixed, such as storing wood, metal, concrete blocks, bricks, tiles, and stones separately.

Preprocessing: Use a loader to transport the garbage to the processing center, and combine manual preliminary sorting to remove visible impurities such as household waste, flammable and explosive materials, etc.

2. Fine sorting:

Mechanized sorting: Using sorting equipment such as vibrating screens, drum screens, air separators, magnetic separators, etc., garbage is classified into different categories based on its particle size, density, magnetism, and other characteristics, such as coarse aggregate, fine aggregate, wood, metal, plastic, glass, etc.

3. Crushing and screening: Crushing concrete blocks, bricks, and other materials into aggregates of a certain particle size for the production of building materials such as recycled concrete, recycled bricks, and subgrade cushions.

Recycling: After treatment, waste wood may be used as biomass fuel or remanufactured into new wood products; Scrap metal can be recycled for steelmaking; Waste plastics, waste glass, etc. can also be recycled and reused.

Other processing methods:

4. Low temperature incineration: Some waste that cannot be effectively resourceful can be considered for low-temperature incineration treatment to obtain heat energy and reduce volume.

5. Landfill treatment: After strict classification and resource utilization, the remaining waste that meets environmental standards can be safely landfilled to prevent environmental pollution.

6. Biodegradation: For waste containing organic components, it can be degraded through biotechnology and converted into fertilizers or other environmentally friendly products.

In short, the goal of modern construction waste management is to prioritize resource utilization, minimize the proportion of landfill and incineration, and achieve circular economy and sustainable development. Each country and region will develop corresponding refined processing procedures and standards based on their actual situation and regulatory policies.
