Sand and gravel are in short supply, and cement continues to soar! The recycling of construction waste has been supported by the national and local governments. This project continues to be hot and attracts the attention of batches of investors, but can the construction waste be used after being crushed? The following is a detailed introduction.
Can construction waste be used after being crushed?
Fine aggregate: refers to sand with a particle size of 0.25-0.5mm, which is mainly used to produce mortar and replace natural sand;
Medium aggregate: refers to stones with a particle size of 5-20mm, which are directly used for paving the road base, or as raw materials such as recycled bricks, permeable bricks, etc., and the requirements for particle size are not very high;
Coarse aggregate: refers to stones with a particle size of 16-40mm. The main purpose is to configure recycled concrete. It needs to be complete in particle shape and multi-angle and multi-edge. It can also be used as a material for paving the road base together with medium aggregate;
Use of construction waste
- 1. Scrap iron and steel are processed into new steel after sorting and centralized re-casting;
- 2. The waste wood is sorted and transported to the wood factory for the manufacture of recycled wood;
- 3. Muck is used for road construction, pile filling, foundation foundation, etc.;
- 4. The waste bricks and tiles are crushed to regenerate raw materials, which are used to recycle bricks, floor tiles, wall panels and other building materials;
- 5. The waste concrete is crushed to regenerate the aggregate, which is used for concrete and mortar of the corresponding grade;
The machine for crushing construction waste is also called a construction waste mobile crushing station, which directly removes iron and multi-stage crushing of large pieces of construction waste, and sieves it according to certain discharge specifications. Flexible, can be flexibly matched according to the processing raw material situation, output and finished material requirements, the classification is as follows.
- 1. According to the driving device: it is divided into tire type and crawler type. The tire is semi-mobile and needs to be pulled by a semi-trailer. The output of the large-scale construction waste pulverizer is less than or equal to 650 tons/hour; , the output is less than or equal to 580 tons/hour.
- 2. According to the collocation of the crusher: it is divided into jaw type, cone type, counterattack type, heavy hammer type and screening machine, etc. Due to different equipments, it can be further divided into coarse crushing, medium/fine crushing and screening;
Bellian Machine, as a powerful manufacturer for decades, has independently developed production equipment, and has quality inspection personnel to ensure the quality of the equipment, direct sales and supply, no agents, one-stop service, allowing you to save worry and money.
