Abstract

The invention provides an efficient preparation systemfor waste concrete regenerated sand powder. The preparation system comprises a screening system, a blending system and a regeneration system, the screening system is connected with the blending system and the regeneration system, a first cleaning device is arranged in the screening system, and a second cleaning device is arranged in the regeneration system. The cleaning devices are arranged in the screening system and the regeneration system, and the cleaning devices are connected with a crushing machine, so that all-component recycling of waste concrete is achieved, part of crushing, grinding and sorting processes and equipment are introduced from the industries of ore processing, cement grinding and the like, and the technical problems that existing equipment mainly suitable for impact / impact crushing of homogeneous materials, for example, impact type and hammer type crushers for crushing waste concrete, causes serious environmental pollution in the crushing process.

Description

technical field [0001] The invention relates to the technical field of solid waste recycling, in particular to a high-efficiency preparation system for recycled sand powder from waste concrete. Background technique [0002] Natural sand is a non-renewable resource in a short period of time. With the increasing development of infrastructure and the gradual implementation of environmental protection and sustainable development policies, natural sand resources are increasingly in short supply in many areas of my country, especially for concrete mixing. The price of sand is on the high side at the peak of sand use, and there is even no natural sand available. In addition to being widely found in construction waste, waste concrete also exists in concrete production enterprises, engineering quality inspection units, roads or construction sites. Concrete not only solves the pollution problem of waste concrete to the environment, but also saves natural sand and gravel resources. At ...
