Description

Technical Field

[0002] my country generates a large amount of construction waste every year. The traditional way of dealing with it is mainly landfill. This treatment method easily causes waste of resources and causes water and soil pollution in the landfill area. At the same time, the transportation of construction waste will also cause resource loss and increase in carbon emissions. Through "making bricks from construction waste" to achieve the recycling of solid waste resources, the utilization rate of construction waste can reach more than 80%, effectively alleviating the transportation and space storage problems of construction waste. It has high flexibility, no need for incineration, low carbon and energy saving, and achieves the ideal environmental protection requirements of near zero pollution and zero emissions.

[0003] To make bricks from construction waste, it is first necessary to use a crushing device to crush the construction waste.

However, a large amount of dust will be generated when the crushing device is used, which affects the environment and is not good for the health of workers. For this reason, we propose a crushing device for making bricks from construction waste with a dust reduction function. Utility Model Content
