Device for separating waste concrete to manufacture sand, stone and silicate aluminate material

Abstract

The invention relates to a device for separating waste concrete to manufacture sand, stone and silicate aluminate material. The device comprises a disintegrating and repairing device, a separating device and a bracket; a material outlet of the disintegrating and repairing device communicates with a material inlet of the separating device; and the disintegrating and repairing device and the separating device are fixedly arranged on the bracket. The device is simple and has simple process, little land occupation, little investment, and effective and high-efficiency disintegration; the device canbe promoted to recycling of the waste concrete, and is beneficial to protecting the social ecological environment and the natural environment and beneficial to promoting employment opportunities; andmeanwhile the device can achieve the effective resource recycling of the three original constituent materials (sand, stone, binder) in the waste concrete and can greatly reduce the consumption of limestone, clay and shale of the limited natural resources during the cement production for the economic construction.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a device for separating waste concrete into sand, stone and aluminosilicate materials. Background technique [0002] As we all know, inorganic building materials, especially commonly used concrete, mortar, and cement bricks, are mainly composed of composite building materials in which cementitious materials, sand materials, and / or stone materials are solidified together. The scale of my country's infrastructure is huge, and the huge amount of construction projects across the country requires a large amount of sand, stone and cement raw materials. The mining and supply of sand and stone raw materials required by the huge infrastructure scale will continue to have an irreversible impact on the environment; at the same time, The production of a large amount of cement needed for engineering construction continues to consume high energy consumption and high p...

Low investment, low cost local centralized processing
