1、Background and program introduction

With the acceleration of urbanization, the incineration of domestic waste to generate electricity has become the mainstream treatment, but the incineration of slag still contains a large number of recyclable metal resources (such as iron, copper, aluminum, stainless steel, etc.). If direct landfill, not only waste of resources, but also cause environmental pollution.

Life waste incineration slag metal sorting overall solution through crushing, screening, magnetic separation, gravity sorting, eddy current sorting and other physical methods, efficient recovery of valuable metals in the slag, to achieve the utilization of resources, reduce the amount of landfill, and enhance the economic and environmental benefits.

2, slag incineration slag metal sorting process

Pre-treatment stage
Uniform feeding → Grid sieve to remove large debris → Tumbler screen grading → coarse + fine crushing shaping

Metal sorting stage
Multi-stage magnetic separation (ferrous metal recovery) → Eddy current sorting (non-ferrous metal extraction) → Jig + shaker (precious metal fine sorting)

Post-treatment stage
Fine screening → spiral sand washing and dewatering → filter press slag-water separation → product slag resourceization

Environmental protection closed loop
The whole cycle of water system, no chemical additive, no secondary pollution.

4、Waste incineration slag can be recycled metal

• Iron metal

• Copper (brass, copper)

• Aluminum and alloy

• Stainless steel

• Copper sand, zinc and other non-ferrous metals

• Trace gold, silver and other precious metals

• Finished slag (building materials aggregate)

5, domestic waste incinerator slag sorting program advantages and features

• ✅ High-efficiency sorting: multi-stage crushing + intelligent sorting, metal recovery rate industry-leading

• ✅ Energy saving and environmental protection: recycled water system, no chemical pollution

• ✅ Fast return on investment: 10-18 months to recover costs, metal earnings continue to be stable

• ✅ Intelligent control: PLC automation, easy operation and low labor cost.

• ✅ Flexible adaptation: customized solutions according to treatment scale (200-2000 tons/day)

• ✅ High resource utilization rate: the tailing reaches GB/T25032-2010 building materials standard, which can be used for making bricks, road base materials, etc.

6、Customer representative of incinerator slag of domestic waste power plant

• A state-owned enterprise in Jiangsu, China, 1000 tons / day project

The above are some of our projects, we provide a total solution from design to installation and commissioning.

7、Resource utilization of tailings after sorting

The treated tailings meet the standard of building materials, and can be used:

• Raw material for brick making

• Cement Admixture

• Roadbed bedding

• Concrete aggregate, etc.

Wecan provide sorting after the tailing slag resource utilization technology and the overall program to achieve the slag resource utilization rate of 100%, waste power plant solid waste 0 landfill.

8、 Garbage incinerator slag treatment program configuration

• Program A (metal recovery type): focus on maximizing the recovery of metal, relatively concentrated investment, fast return. (Recommended, is now the mainstream of domestic waste incinerator slag sorting treatment)

• Scheme B (comprehensive utilization type): "Scheme A + tailing slag deep processing". Output of metals and building materials products (such as new building materials, roadbed materials, etc.), to achieve the full quantitative utilization of solid waste and maximize the comprehensive benefits.

9、Customized service/service support

• Tailor-made: according to the treatment capacity, site, budget to provide personalized waste slag sorting program

• Process design: waste incineration slag sorting process design, site planning, drawing design

• Equipment selection: modular design, flexible combination of core waste incinerator slag sorting equipment

• Full-service: project design → equipment manufacturing → door-to-door guidance and installation → on-site commissioning → staff training → after-sales service

• Technical support: 24-hour response, remote diagnosis + on-site service
