Abstract:A new type of metal classification briquetting machine based on PLC,which was used to solve the problem of classification suppression of metal-slicing waste,was developed to achieve the goal of recycling and reuse.Mechanical system structure,working process,hydraulic system structure,PLC controlling system and the working principle of the equipment were introduced.The block-press machine,which can be operated manually and automatically,is good for popularization and application because of its improved stability and production efficiency,as well as its strong functional applicability.
