Abstract

The invention discloses equipment and a method for recycling aggregate from waste concrete, and relates to the technical field of waste concrete recycling. The equipment comprises a concrete crushing mechanism, the concrete crushing mechanism is provided with a shell, the top of the shell is fixedly connected with a rotary stirring mechanism, the concrete crushing mechanism is fixedly connected with the rotary stirring mechanism, the rotary stirring mechanism is provided with an extrusion block, and the extrusion block is fixedly connected with the shell. The outer wall of the extrusion block is fixedly connected with a crushing mechanism, and the rotary stirring mechanism is fixedly connected with the crushing mechanism. According to the equipment and the method for recycling the aggregate from the waste concrete, the extrusion block impacts on the inner wall of the shell, so that the extrusion block extrudes gas in the cylinder, blowing-out of airflow is accelerated, the airflow can blow up dust in the cylinder, and the influence of dust accumulation on concrete smashing is avoided; and the molecular spacing in the gas is reduced.

Description

technical field [0001] The invention relates to the technical field of waste concrete recycling, in particular to a waste concrete recycling and regenerating aggregate equipment and a method thereof. Background technique [0002] In recent years, my country's construction industry has risen rapidly. As a widely used building material, concrete is mass-produced. At the same time, the demolition of old buildings also produces a large amount of waste concrete. On the one hand, the production of new concrete consumes a lot of natural resources such as sand and gravel, and on the other hand On the one hand, the accumulation of waste concrete causes environmental pollution and affects social order. The efficient recycling of waste concrete can not only solve the environmental pollution caused by waste concrete, but also can be used as raw material for new concrete to be put into production, reducing the exploitation of natural sand and gravel resources. The development of circular e...
