Solid construction waste processing and treating system

Abstract

The invention discloses a solid construction waste processing and treating system which comprises a compound crusher, a double-cone crusher, a high-frequency vibrating screen, a water separator and a stone surface treatment machine, wherein solid construction waste with the rated size is crushed into the size less than that of preset particles by the compound crusher and enters the double-cone crusher to be further crushed into particles with the size less than that of another preset particles; the crushed particles are fed into the high-frequency vibrating screen and are separated to be in grades which are smaller than or equal to a large grade, a middle grade and a small grade, the particles of different grades are fed into the water separator to separate out stones, red bricks, pure concrete particles, as well as remove floating matters; and finally, the stones with different particle sizes are fed into the stone surface treatment machine, and the concrete layers on the surfaces of the stones are removed. The system is simple in structure, the stones and other building materials which accord with the building standard can be treated, waste materials can be changed into valuable materials, and the system is environment-friendly.

Description

technical field [0001] The invention relates to a system for processing solid construction waste. Background technique [0002] A comprehensive treatment method for construction waste disclosed in Chinese patent document CN1990129, first transports the construction waste produced in the demolition of buildings, house decoration and road reconstruction to the processing site, and then manually removes the construction waste that can be directly Recycled materials, such as metal materials, wood materials and plastic materials, are sorted and classified, and directly supplied to the corresponding companies for processing. For large pieces of waste concrete, waste bricks, marble and other materials in construction waste, use a large hammer or crusher to crush them to a size that the crusher can crush, generally less than 100mm, and then use a stone crusher to crush them to the size of the building. The required stones and sand, and then the above mixture is classified into coar...
