Method for treating inorganic solid waste and application

Abstract

A process for reclaiming the inorganic solid waste (waste silicon, waste concrete blocks, coal gangue, and slags) includes crushing to less than 400 mm for granularity, removing impurities, breaking to less than 80 mm for granularity to obtain the reclaimed aggregate, classifying, magnetic dressing, flushing dressing, and floatation. Said reclained aggregate can be used for road bed or concrete.

Description

technical field

[0001] The invention relates to a processing method for processing construction waste, waste rocks, coal gangue, blast furnace slag and other agglomerated wastes into recycled materials.

[0002] The invention also relates to the use of recycled material for processing. Background technique

[0003] With the development of urban construction, more and more construction waste is discharged from the demolition of urban buildings, which not only occupies land, pollutes the environment, but also causes waste of resources. Therefore, in order to solve this problem, as the Chinese Patent Publication No. CN1298772A discloses a kind of invention patent for the processing and recycling method of construction waste. Its processing process is to manually separate the waste bricks and waste concrete blocks, and then crush them to a particle size of less than 200mm, and remove impurities such as metal objects and wood blocks; and then mechanically crush them to a particl...
