Crushing is one of the important auxiliary operations in the construction waste treatment process. The main purpose is to reduce large material particles into smaller and more uniform particles to improve the efficiency and quality of sorting. There are two methods of crushing construction waste: mechanical crushing and physical crushing. Mechanical crushing uses various machines to crush solid waste. There are mainly jaw crushing, hammer crushing, roller crushing, impact crushing, impact crushing and shear crushing. The crusher is used to generate strong external force on the construction waste materials to force the waste materials to break and break into smaller materials. According to the characteristics of the force exerted on the broken materials, the crushing methods are divided into: impact, shearing, extrusion, grinding, shredding and other categories. Bulk materials are generally crushed and extruded. The grinding method is often used for fine grinding of small pieces of materials. The materials are ground into fine particles by friction between two metal surfaces or grinding bodies of various shapes.
Any kind of crushing generally does not use only one method for crushing, but uses two or more methods combined for crushing, such as: extrusion and bending, impact and grinding, etc. Which one to use must be based on the physical properties of the material. Determine the nature, size of the material and the degree of crushing required. For example: hard materials are crushed by extrusion and impact, brittle materials are crushed by extrusion belt grinding, and brittle and soft materials are crushed by splitting and impact.
Henan Global Heavy Industry took the lead in conducting in-depth research and development of construction waste resource treatment technology, and launched many construction waste-related environmental protection equipment such as complete sets of construction waste treatment systems, construction and decoration waste treatment systems, construction waste flotation machines, and construction waste sorting machines. We can also develop different solutions based on customer needs, aiming to maximize customer satisfaction and effectively solve customer difficulties and pain points.
Scope of application:
1. Many wastes in construction waste can be reused as renewable resources after sorting, rejecting or crushing. For example: scrap steel bars, scrap iron wires, scrap wires and various scrap steel accessories and other metals can be reprocessed into various specifications of steel after sorting, concentration and re-melting;
2. Waste bamboo wood can be used to make artificial wood;
3. After being crushed, waste materials such as bricks, stones, and concrete can be used as sand substitutes for masonry mortar, plastering mortar, concrete cushion, etc. It can also be used to make building materials such as blocks, paving bricks, and checkered bricks. products.
