Efficient crushing device for construction waste recovery

Abstract

The invention discloses an efficient crushing device for construction waste recovery. The efficient crushing device comprises a box body, and a preliminary breaking mechanism is fixedly arranged at the upper part of the inner chamber of the box body. The preliminary breaking mechanism comprises a fixed breaking plate, a movable breaking plate, a disc, a hydraulic cylinder and a motor. An iron removal mechanism is arranged under the preliminary breaking mechanism, and a first crushing roller and a second crushing roller are arranged under the iron removal mechanism. In the falling process of massive construction wastes, the preliminary breaking mechanism breaks the massive construction wastes step by step, so that metal in the wastes is exposed. Moreover, follow-up crushing is facilitated, and the crushing efficiency is improved. The size of broken particles of construction wastes can be adjusted, and the breaking degree can be adjusted. The construction wastes are subjected to second level of crushing through the first crushing roller and the second crushing roller, and the construction wastes are crushed more thoroughly. The crushing effect is good, and the crushing efficiency is high. The metal, such as steel bars in the construction wastes can be removed through the iron removal mechanism and are collected. The efficient crushing device has the advantages of simple structure and convenience in operation.

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 ...
