What's left in the end is concrete blocks and brick slag.
The construction waste generated after the blasting demolition of the building is pretreated to reach the particle size that can enter the crusher, and then sent to the vibrating feeder by the excavator. The iron separator is placed on the top of the impact crusher and the discharge belt conveyor to separate the steel bars in the construction waste, and then the materials enter the mobile screening station for screening, the large materials are returned to the impact crusher for cyclic crushing, and the small materials are conveyed by the belt conveyor. to each finished stockpile.
At present, the commonly used equipment for processing construction waste on the market is a mobile crushing station. In addition to the feeding system, crushing system, screening system, and conveying system, the mobile construction waste treatment production line is equipped with its own power device according to the mobility of mobile operations. According to different crushing and screening operation processes, the structure of the equipment is also different.
