ABSTRACT
The structural design topic of the double-shear solid waste crusher comes from the needs of actual production and environmental protection. With the rapid development of urbanization and industrialization, the amount of solid waste is increasing, and how to treat these wastes efficiently and environmentally has become an important issue. As an effective crushing equipment, double-shear solid waste crusher has a wide application prospect. By analyzing the physical properties and components of solid waste, the crushing requirements can be better understood, and then design the crusher structure that is more suitable for the actual needs. Moreover, this study aims to improve the stability and efficiency of the crusher. Therefore, the actual source of the topic has important practical significance and application value.
This paper aims to design a double-shear solid waste crusher to meet the crushing requirements of solid waste. First, the crushing requirements of solid waste are determined by analyzing its physical properties and composition. Then, based on these requirements, the corresponding structural design is performed. In the structural design process, the optimization of the tool mechanism is specially considered to solve the problems of the possible tool tooth failure during the crushing process of the biaxial shear crusher. At the same time, according to the characteristics of the external size and hardness strength of solid waste, targeted design to ensure the smooth progress of crushing work. This study not only provides effective equipment for the crushing treatment of solid waste, but also provides a useful reference for similar mechanical design.
