Technical Field

[0001] The utility model relates to the technical field of garbage crushing, in particular to a construction garbage crushing device. Background Art

[0002] With the continuous acceleration of urbanization, the amount of construction waste generated and discharged in cities is also growing rapidly. Among them, construction waste accounts for a considerable proportion, accounting for about 30% to 40% of the total amount of waste. According to a rough statistics of the loss of construction materials for buildings such as brick-concrete structures, fully cast-in-place structures and frame structures, during the construction of every 10,000 square meters of buildings, only 500 to 600 tons of construction waste will be generated. In my country, more than 100 million tons of construction waste is generated and discharged every year in construction alone. In addition, the amount of construction waste generated by building decoration, demolition, and building materials industry will reach hundreds of millions of tons. There are at least the following disadvantages in the use of existing construction waste crushing devices: 1. The crushing fineness is not enough, which affects the subsequent secondary utilization; 2. When the existing equipment is used to treat construction waste, it is impossible to perform targeted crushing according to the size of the garbage, which reduces the crushing efficiency. Therefore, we have launched a construction waste crushing device. Utility Model Content
