Abstract

The invention discloses construction waste sand-making equipment, which is mainly used for solving a problem that the existing construction waste cannot be reasonably utilized. The construction waste sand-making equipment structurally comprises a transfer device, a sand-making system, a screening device and a tee joint, wherein the transfer device and the sand-making system are connected by a belt conveyor; the sand-making system and the screening device are connected by a conveying device; a discharging hole of the screening device is connected with the tee joint; a material return hole is formed in one side of the screening device; the material return hole is connected with the transfer device by a returning belt conveyor. The equipment disclosed by the invention is convenient to use, cost-saving, suitable for a production line of construction waste and common stone sand making, capable of realizing comprehensive utilization of construction waste, environmental friendly and energy-saving.

Description

technical field [0001] The invention relates to a sand making equipment, in particular to a construction waste sand making equipment. Background technique [0002] Facing the depletion of domestic natural sand, river sand and other resources and the difficult technical problems of sea sand, it has become inevitable for the development of the industry to replace natural sand with machine-made sand in the future. Compared with natural sand, machine-made sand has the advantages of continuous gradation, flexible sand and gravel field transition, and simple and extensive raw material sources. In the current situation where natural sand resources are exhausted, the future market demand for machine-made sand equipment is being optimistic by countless people. [0003] At the same time, construction waste has exacerbated the tension in urban land and resources in my country, seriously affecting the coordinated development of social economy and ecological environment. Cities across t...
