Efficient crushing device for construction waste recovery

Abstract

The invention discloses a high-efficiency crushing device for recycling construction waste, which includes a box body. A pre-crushing mechanism is fixed on the upper part of the inner cavity of the box. The pre-crushing mechanism includes a fixed crushing plate, a movable crushing plate, a disc, a hydraulic cylinder and Motor, under the pre-crushing mechanism, there is an iron removal mechanism, and under the iron removal mechanism, there are first crushing rollers and second crushing rollers. The construction waste is crushed to expose the metal in the waste, which is beneficial to the subsequent crushing, improves the crushing efficiency, and can adjust the size of the crushed particles of the construction waste and adjust the degree of crushing. There are first crushing rollers and second crushing rollers. Secondary crushing is carried out, the crushing is more thorough and sufficient, the crushing effect is good, and the efficiency is high. It is equipped with an iron removal mechanism to remove and collect metals such as steel bars in construction waste. The structure is simple and the operation is convenient.

Description

technical field [0001] The invention relates to a crushing device, in particular to a high-efficiency crushing device for recycling construction waste. 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 directly for crushing, and construction waste often contains steel bars, steel bars and other metals, which are directly crushed by crushing rollers, which is easy to use The crushing roller is damaged, and the device is stuck, which seriously affects the service life of the device, and even safety accidents ...
