Problems solved by technology
[0002] With the development of social economy, our country continues to deepen urbanization construction, coupled with the improvement of consumption level, there are more and more construction waste in cities, most of which are landfilled and piled up by construction units without any treatment. It not only affects the environment, but also wastes renewable energy. At present, the construction waste crushing devices used by enterprises generally use crushing rollers for direct crushing. However, some construction waste is too large to be crushed directly. It needs pre-treatment, single crushing, The crushed garbage particles are large and inconvenient to handle

The invention provides a construction waste pretreatment and pulverizing and grinding device which comprises a supporting and shock absorption device, a pretreatment and pulverizing device and a pulverizing and grinding device body; the supporting and shock absorption device comprises supporting columns and shock absorption device bodies; the upper end faces of the supporting columns are welded at the lower end faces of bearing plates; the shock absorption device bodies are welded at the lower ends of the supporting columns; the pretreatment and pulverizing device comprises a feed box and a pre-pulverizing box; the pre-pulverizing box is welded on a pulverizing and grinding box; the feed box is welded on an upper cover plate; the pulverizing and grinding device body comprises the pulverizing and grinding box and a material guide cover; the pulverizing and grinding box is welded on the left side of one bearing plate and on the right side of the other one bearing plate; and the material guide cover is fixedly arranged at the lower end of the pulverizing and grinding box through second nuts and second bolts. Large waste is pulverized in advance through the pretreatment and pulverizing device, and after the pre-pulverizing, the waste is pulverized through the matching of rotary pulverizing blades and fixed pulverizing blades, and is subjected to grinding treatment by a grinding rotating column, so that the pulverizing efficiency of construction waste is improved.
Description
technical field [0001] The invention relates to a construction waste treatment device, in particular to a construction waste pretreatment crushing and grinding device. Background technique [0002] With the development of social economy, our country continues to deepen urbanization construction, coupled with the improvement of consumption level, there are more and more construction waste in cities, and most of the construction waste is arbitrarily landfilled and piled up by construction units without any treatment. It not only affects the environment, but also wastes renewable energy. At present, the construction waste crushing devices used by enterprises generally use crushing rollers for direct crushing. However, some construction waste is too large to be crushed directly. It needs pre-treatment, single crushing, The crushed garbage particles are relatively large and inconvenient to handle. Contents of the invention [0003] The object of the present invention is to pro...
