Description

Technical Field

[0001] The utility model belongs to the technical field of crushing equipment, and more specifically, particularly relates to a solid waste crushing device. Background Art

[0002] Solid waste, also known as solid waste, refers to solid or semi-solid substances generated in human daily life, industrial production, construction, agriculture and other economic and social activities that have lost their original use value or have not completely lost their use value but have been discarded or are intended to be discarded. Different solid wastes are treated in different ways. For example, some waste from construction contains hard materials such as steel bars and cement, which need to be broken by blunt impact. For solid waste in daily life, such as plastic bottles, waste cloth, cables, etc., this type of solid waste cannot be broken by impact force during processing, and needs to be broken by shear force. However, due to the small thickness or diameter of this type of material and its high toughness, it is easy for material accumulation to occur during the crushing process, resulting in low crushing efficiency.

[0003] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a solid waste crushing device is provided to achieve a more practical purpose. Utility Model Content
