Description

Background technique

Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals.

Concrete is the most commonly used material in construction, and it is also the most frequently used material. When the building needs to be demolished and rebuilt, the construction waste (concrete blocks) generated accounts for a large proportion, and the construction waste of concrete blocks can be processed and recycled. However, it is necessary to crush large pieces of concrete into small granular concrete blocks before they can be used. At present, conventional concrete crushing equipment only uses a single crushing method to crush concrete blocks, such as drill bit crushing and stamping crushing, but the effect is single. The speed is slow, and not all the crushed concrete is qualified.
