INDUSTRY CHALLENGES

Industry Challenges

Solid Waste Encroachment

Urban household waste and industrial solid waste disposal pressures are surging; traditional landfill and incineration methods carry high environmental costs and significant compliance risks

Energy Transition Pressure

Energy-consuming enterprises such as industrial boilers, cement kilns, and thermal power plants face the dual challenge of fossil fuel price volatility and carbon emission reduction

Resource Misallocation

Large volumes of low-value solid waste cannot be efficiently converted into energy, wasting resources while compounding environmental burdens

APPLICATION CASE

Benchmark Case Showcase

CASE 01

Senge Environmental Industrial Waste Shredding and Sorting Project

Location
Jiangsu
Processing Capacity
100 t/d
Process Route
Coarse crushing + ferromagnetic metal sorting + particle size screening + density separation + fine crushing

The project primarily processes general industrial solid waste and combustible materials separated from renovation waste, with a processing capacity of 100 t/d. It adopts a process route of "coarse crushing + ferromagnetic metal sorting + particle size screening + density separation + fine crushing." The system mainly consists of a dual-shaft coarse shredder, electromagnetic self-discharging iron remover, trommel screen, high-pressure density separator, and single-shaft fine shredder. Inorganic components in the waste — brick, tile, stone fragments, and sand/gravel (<20mm) — along with metals are separated out, while combustible materials are finely shredded to a uniform particle size (<=100mm). The output can be baled via a baler or directly loaded for transport to cement plants for incineration or external sale. Output categories include ferromagnetic metals, inert non-combustibles, sand/gravel, and finished SRF fuel.

CASE 02

Aituo Environmental Industrial Solid Waste Processing Project

Location
Zhejiang
Processing Capacity
100 t/d
Process Route
Coarse crushing + ferromagnetic metal sorting + fine crushing

The project primarily processes mixed general industrial waste and combustible materials separated from renovation waste, with a processing capacity of 100 t/d. The system adopts a process route of "coarse crushing + ferromagnetic metal sorting + fine crushing" and mainly consists of a coarse shredder, electromagnetic self-discharging iron remover, and fine shredder. After two-stage crushing, material size specification: >=85% by weight <=150mm, with some flexible material pieces potentially exceeding 150mm.

CASE 03

Guangdong Dongguan Qishi Industrial Solid Waste Shredding and Baling Project

Location
Guangdong
Processing Capacity
200 t/d
Process Route
Coarse crushing + particle size screening + density separation + fine crushing

This project primarily processes general industrial solid waste with a capacity of 200 t/d. It adopts a process route of "coarse crushing + particle size screening + density separation + fine crushing." The system mainly consists of a coarse shredder, electromagnetic self-discharging iron remover, trommel screen, high-pressure density separator, and fine shredder. Material undergoes coarse shredding and trommel screening, followed by secondary iron removal to extract ferromagnetic metals, then enters a high-pressure density air separator where lightweight and heavy materials are separated by airflow. Heavy materials drop directly into a heavy inert material temporary storage area below, while lightweight materials continue along the conveyor into the fine shredder, where particle size is further reduced. The final output is conveyed into a distribution belt conveyor, where it can either follow the main route to the downstream baling and wrapping system for baling and wrapping operations, with bundled bales stacked in the product stacking area, or be diverted to the bypass route for direct entry into the briquetting and pelletizing system, with the final product stacked in the pelletized product storage area.
