What equipment is required for recycling construction waste

Construction waste has long been discarded as refuse in open areas, with construction firms even paying others to dispose of it. Consequently, procurement costs for recycling construction waste are extremely low. After processing, construction waste can be used to produce numerous products, such as sand and gravel aggregates, concrete, and non-fired bricks. What equipment is required for recycling construction waste?

First, understand the processing techniques involved in a construction waste recycling production line:

1. Sorting

Construction waste is highly heterogeneous, containing not only concrete blocks but also glass, timber, plastics, metals, cables, etc. These must be pre-sorted beforehand, as separated materials can be sold separately.

2. Iron Removal

Iron components within construction waste resist crushing during subsequent processing stages. Larger pieces may even damage equipment. Therefore, magnetic separators are employed to remove residual metals from the concrete aggregate mixture.

3. Pre-screening

This stage typically employs circular vibrating screens to remove silt, sand, and smaller particles from the mixture.

4. Crushing

The crushing process comprises three stages: primary, secondary, and tertiary crushing.

Primary crushing is usually performed by jaw crushers, which offer high crushing ratios, strong compressive strength, large feed openings, and high throughput, making them the most widely used equipment in crushing operations.

The medium crushing stage employs impact crushers, which can separate reinforcing steel from concrete materials during processing.

Fine crushing is usually performed by impact sand makers, which refine the output from secondary crushers to produce particles meeting specified size requirements.

5. Screening

This stage involves two screening processes: first, screening materials from each crushing stage, with undersized particles returned to the preceding crusher for reprocessing; second, grading the finished sand by particle size.

Current equipment production technology for construction waste processing is well-established, with numerous manufacturers offering stationary crushing and screening solutions.
