Specialized Crushing And Screening Equipment For Metal And Concrete Building Materials

Product Description Of Metallurgy Machine

The comprehensive utilization project of construction waste crushing stations can comprehensively utilize the resources of construction waste. It not only enables the "reduction, resource utilization and harmless treatment" of construction waste, reducing its impact on the environment, but also adopts scientific management and effective measures to reduce and reuse it. Over 90% of construction waste consists of building materials such as waste concrete, waste bricks and waste mortar. By using crushers to classify, crush and screen construction waste, it can be turned into treasure and rationally recycled and reused. After sorting, rejection or crushing, it can be reused as a recyclable resource and become the second resource in the construction industry. Metals such as scrap steel bars, scrap iron wires, scrap electrical wires and various scrap steel fittings, after sorting, concentrating and remelting, can be reprocessed and manufactured into steel of various specifications. Waste materials such as bricks, stones and concrete, after being crushed, can be used as substitutes for sand in masonry mortar, plastering mortar, concrete bedding, etc.

They can also be used to make building materials such as blocks, paving bricks and lattice bricks. Making bricks from construction waste features "three savings", "three cleanings" and "three modernizations". It also has the characteristics of energy conservation, water conservation, coal conservation, clean air, clean environment and clean production. It can truly achieve the reduction, resource utilization and harmless treatment of construction waste. Thus, a transformation from the traditional model of building materials → buildings → construction waste to a comprehensive utilization model of building materials → buildings → construction waste → recycled raw materials can be achieved.

The process of construction waste treatment and the reuse of new materials

The construction waste stored in a centralized manner enters the professional construction waste crusher, where it is crushed into powder and concrete sand and gravel particles. Then, it is conveyed to the vibrating screen through a conveyor belt for screening, separating out the lighter wood chips. Next, the metals such as steel bars and iron wires in the construction waste are separated, and the steel bars, iron wires, etc. are attracted and separated for recycling by a magnetic device. Thirdly, the particles of different sizes and specifications produced after crushing are conveyed to the silos respectively by the conveyor belt through different screening devices on the vibrating screen for future use.

Construction waste goes through several steps

classification → crushing → dust removal → screening to obtain finished sand and powder of different specifications. These raw materials go through more than ten processing techniques such as raw material activation, physical treatment, addition to the formula for stirring, and reasonable gradation. The recycled and environmentally friendly products produced have obvious advantages in terms of compressive strength, flexural strength, and heat insulation. More than 40 kinds of environmentally friendly building materials can be developed from construction waste.

1. The particle size of the finished product is below 12mm. These raw materials are the best for manufacturing environmentally friendly non-fired bricks and cut bricks. The dust collected by the dust collector can also be used to make non-fired bricks or cut bricks. The solid brick series has the characteristics of strong anti-weathering ability and no radiation, and its service life is more than 20 years longer than that of traditional fired bricks.
2. The finished product is 12-30mm bone and stone materials. These aggregates can be used as auxiliary materials for the foundation of buildings or roads. The hardness coefficient of construction waste is between 2 and 3. After crushing, materials with this hardness coefficient can be fully used as building auxiliary materials.
3. The finished materials can be used for making concrete mixtures, bricks and tiles, road foundations, and other building auxiliary materials, etc.
4. The finished materials after processing construction waste can be used to make lightweight aggregate concrete, lightweight slabs for building partition walls, lightweight aggregate concrete small hollow blocks, and at the same time, it can produce recycled aggregate building panels, recycled aggregate mortar and other recycled products.
5. It can be made into various building materials and products such as paving bricks, lattice bricks, partition wall bricks and grass planting bricks that are widely used on municipal roads. Grass pavers are of high strength, environmentally friendly, anti-slip and durable, and can be used on the roads of streets, squares, gardens, etc

Production process flow Of Metallurgy Machine

This project, through the classification, crushing and screening of construction waste, produces aggregates that partially replace natural sand and gravel. Some of the aggregates are used as raw materials for deep processing by enterprises, combined with cement, to produce ready-mixed mortar, cement admixtures, concrete products and other products. The remaining part is sold as commercial aggregates to concrete mixing plants, ready-mixed mortar stations, and backfilling of road structure foundations, etc. The selected fine powder is used for the production of concrete products, and the yellow soil screened out at the primary stage can be used as backfill soil or supplied to the garden department as greening soil.
