Tailing &Construction Waste Crushing Project Profile

From collection of tailings and building wastes to integrated treatment, from green building material production to sales of finished products, this project forms a complete operation mode, maximizing the use of tailings and building wastes.

Tailing &Construction Waste Crushing Design Scheme

1) When the raw materials are building wastes…

Firstly, building wastes are sent by vibrating feeder to the jaw crusher for primary crushing. After coarse crushing and magnetic separation, the materials are classified by screen where rubbish including cloth, plastic bags and lumber is screened out.

The materials prescreened enter to the buffer material bin, then to the impact crusher. After being processed by impact crusher, de-ironer would remove the magnetic unbreakable material including steel and iron wire. Then screener classifies the materials again into 3 levels --- materials( ≥40mm) which would be sent back to impact crusher to be processed into particles with size within 0-40mm, materials (10-40mm) which enter the aggregate production system for dressing, materials( 3-10mm, 0-3mm) which would enter the storage bin and the fine materials (0-3mm) would be moistened to be used in brick production.

2) When the raw materials are tailings…

Because tailings are hard and wear resistant, cone crusher is recommended. And remaining processing steps are similar to those of building wastes. Say, the materials prescreened enter the buffer material bin, then to the impact crusher. After being processed by impact crusher, de-ironer would remove the magnetic unbreakable material including steel and iron. Then screener classifies the materials again into 3 levels --- materials( ≥40mm) which would be sent back to impact crusher to be processed into particles with size within 0-40mm, materials (10-40mm) which enter to the aggregate production system for dressing, materials( 3-10mm, 0-3mm) which would enter the storage bin and the fine materials (0-3mm) would be moistened to be used in brick production.

The Profit of Tailing &Construction Waste Crushing

Annual Output Value

1) High-quality recycled aggregate (500,000TPY): The market price of recycled aggregate is 33 yuan per ton, so 16.5 million yuan can be earned per year.

2) Dry-mixed mortar (300,000TPY): The market price of dry-mixed mortar is 220 yuan per ton, so 66 million yuan can be earned per year.

Cost Calculation

1) Costs of recycle and transportation: Very often, the transportation distance of tailings and construction wastes is below 30 kilometers. The expenditure is 10 yuan per ton.

2) Costs of material processing: A ton of material costs 10.29 yuan which covers fee of electricity, quick-wear parts, depreciation of equipment and labor.

Profits Calculation

1) The average price of natural aggregates is 33 yuan per ton. So a ton of materials can get 12.71 yuan after subtracting the costs（10+10.29=20.29）And annual profits of high-quality recycled aggregate can reach ¥6.355 million.

2) Provided that the content of magnetic materials like rebar and iron wire is 1%, then the profits got from these materials: 800yuan/ton X 1 million tons X 1% = ¥8 million.

3) Compared to river sand, the dry-mixed mortar (300,000TPY) can save: 30yuan/ton X 300 thousand tons = ¥9 million.

Gross Profits

Disposal fee of building wastes saved annually: 20yuan/ton X 1 million tons = ¥20 million. Annual indirect profits: ¥28.155 million+¥20 million=¥48.155 million
