Construction Waste Treatment Machinery

Construction waste treatment machinery is a set of efficient and systematic equipment, whose working principle is mainly based on physical sorting and processing technologies. Here is a detailed explanation of how construction waste treatment machinery works:

I. Raw Material Reception and Pre-treatment

Construction waste is first transported to the treatment plant by loading equipment (such as loaders, excavators, etc.) and dumped into feeders or hoppers. During the pre-treatment stage, manual or automatic sorting may be required to remove large debris and non-processable items, such as large concrete blocks, rebar heads, etc. This step helps to protect subsequent processing equipment from damage and improves processing efficiency.

II. Crushing

The pre-treated construction waste enters the crusher for crushing treatment. Crushers typically use equipment such as jaw crushers, impact crushers, or cone crushers, and the appropriate crushing method is chosen based on the material characteristics and processing requirements. The crushing process breaks down construction waste into smaller particles or powdery materials, facilitating subsequent sorting and recycling.

III. Screening and Classification

The crushed material is processed through screening equipment such as vibrating screens or drum screens. The screening process separates the material according to particle size, separating recyclable materials such as recycled aggregates. At the same time, further classification processing can be carried out based on the properties of the material.

IV. Magnetic Separation and Air Separation

Magnetic separators utilize the properties of magnetic materials to separate and recover metal-containing construction waste. Air separation equipment uses wind power to separate lightweight materials (such as plastics, paper, etc.) from heavyweight materials. These separated materials can be further recycled or treated harmlessly.

V. Resource Utilization

After the above processing procedures, construction waste is transformed into a variety of valuable resources. For example, recycled aggregates can be used to produce recycled concrete, recycled bricks, and other building materials; separated metals can be directly smelted or reprocessed into new metal products, etc.

Construction waste treatment machinery achieves the resource utilization and harmless treatment of construction waste through a series of efficient and systematic processing procedures.
