Construction Waste Crusher Plant
At the end of 2016, Shibang Industrial and Shanxi Linfen Wah Building Materials Science and Technology Co., Ltd. signed a construction waste and industrial tailings crushing production line with a single value of nearly 10 million yuan. After the project is completed and put into production, it can handle 1 million tons of construction waste and tailings every year.

Urban Construction Waste Processing
Raw materials into the plant stacked in 10,000 square meters of storage shed, from excavators, loaders and other equipment into the raw material warehouse, the raw material warehouse below the vibrating feeder will be even raw material delivered to the coarse crusher jaw crusher crude After the strip separator is separated by the belt type iron remover, the large pieces of rags, wood and other unbreakable organic debris are manually selected and can be sent as fuel to the garbage power plant to generate electricity. Magnetically-selected iron removal of steel, wire and other magnetic unbreakable basic separation of concrete, the armor belt magnetic separator automatically selected, can be sent to steel mill steelmaking.
After the coarsely crushed magnetic separation of construction waste transported by belt conveyor to the special screen for the primary impurity removal soil, construction waste dedicated sieve upper sieve through the mesh with light material separation and dust removal system integration of small dust It can be used as fuel to transport power to the garbage power plant. The lower part of the vibrating screen is made of earth and weathered soft materials (about 15%), which can be used as land for planting organic vegetables , Fruit trees backfill material; also be used to produce stable soil material;
The pre-screened construction waste removed by the belt conveyor into the buffer sub-silo into the impact crusher processing, the belt conveyor and belt remover to remove steel, wire and other magnetic unbreakable material , Into the second screening screening machine for screening, the first layer of sieve on the material +40 mm clean hard materials back to the crusher closed loop crushing 0-40mm, the second layer of sieve on the 10-40mm high strength clean aggregate Enter the high-quality mechanism of gravel production system for self-sharpening, high-quality construction waste production mechanism gravel; the third layer of sieve and sieve material were 3-10mm and 0-3mm fine aggregate, respectively, by the belt Conveyor conveyor through the finished product material into the wind light powder separated into silos, of which 0-3 fine aggregate into the mixing mill wet mixing for brick, brick raw materials.
Mine Tailings Waste Rock Processing
Raw materials into the plant stacked in 10,000 square meters of storage shed by excavators, loaders and other equipment into the raw material warehouse, through the raw material warehouse below the vibrating feeder bar gap, not through the jaw crusher, direct delivery To the jaw crusher belt machine, and then through the tee, not through the pick-up platform, remove impurities special soil, light material slag, directly into the buffer bunker, tailings due to hardness, strong abrasion , Into the cone crusher crushing processing, the conveyor belt and belt remove the iron again removed steel, wire and other magnetic unbreakable, into the second screening screening machine for screening, the first layer of sieve on the material +40 mm clean hard material Return to the counterattack crusher closed loop crushing 0-40mm, the second layer of the sieve on the 10-40mm high strength of clean aggregate into the high-quality mechanism of gravel production system for self-sharpening to produce high-quality tailings gravel ; The third layer of sieve material and sieve material were 3-10mm and 0-3mm fine aggregate, respectively, by the belt conveyor conveyor through the finished product after the wind light material into the powder silo separated for brick, brick raw material.
Second, The Effectiveness Of Assessment
Annual Output Value
- 500,000 tons / year high quality recycled aggregate: In accordance with the high quality recycled aggregate price of 33 yuan / ton, the annual output value: 500,000 tons X33 yuan / ton = 16,500,000 yuan
- 300,000 tons / year dry mortar:In accordance with the average dry mortar price of 220 yuan / ton, the annual output value: 300,000 tons X220 yuan / ton = 66 million yuan
- Total output value: 1650 + 6600 = 8250 ten thousand yuan
Comprehensive Cost Calculation
- Construction waste recycling, transport costs: the mine tailings and construction waste transportation within the city will not exceed 30 kilometers, recycling, transportation costs about 10 yuan / ton;
- Construction waste processing costs: running electricity + wear parts costs + equipment depreciation costs + labor costs ≈ 10.29 yuan / ton; comprehensive cost = recovery, transportation costs + production costs = 10 +10.29 = 20.29 yuan / ton
High-Quality Aggregate Efficiency
- The average price of natural gravel is about 33 yuan / ton, the direct cost saving is 33-20.29 = 12.71 yuan / ton; the annual high quality gravel profit: 12.71 yuan / ton X50 million tons = 6.355 million yuan;
- Recycling of steel, wire and other magnetic impurities calculated by one percent; annual magnetic debris profits about: 800 yuan / ton X100 million tons X1% = 800 million;
- Annual output of 300,000 tons of dry-free dry sand mixed with river sand can save costs: 30 yuan / ton X30 million tons = 9 million yuan; more than the total profit: 6.35 million yuan +8 million +9 million yuan = 2335.5 Million
- Annual construction waste disposal costs savings: 20 yuan / ton X100 million tons = 20 million yuan;
- Indirect economic efficiency generated each year = 2815.5 + 2000 = 4815.5 million.
