Annual construction waste generation exceeds 300 million tons, but its characteristics—high impurity content, low density, and high moisture—often render traditional mining crushing and sorting lines ineffective, leading to screen clogging, failed air classification, and high impurity levels in the final product.

Industry experience has proven that solving this problem cannot rely solely on upgrading individual machines; it requires systematic process design. Mature solutions typically employ a combination of “bag-breaking + pre-screening + multi-stage air classification + optical sorting.” For example, to handle wet and sticky materials, expansion-contraction screens or spiral screens must be used to prevent clogging; for lightweight debris, multi-stage negative-pressure air classification systems must be configured.

As a manufacturer with extensive on-site experience, we advise investors: When planning a waste treatment center, prioritize equipment suppliers with process simulation capabilities. Use digital twin technology to pre-validate production line compatibility and avoid the awkward situation of having to retrofit equipment immediately after startup.
