Development of a dense-phase conveying system of lapillus

Ordinary Lapillus has been thought as an aggregate though, it in this study, it is considered of particulate and being developed based on powder particle technology. The purpose of this study is guaranteeing safety of workers, improving working efficiency and minimization damage to farmlands. We are developing lapillus conveying system. This paper describes the detailed design of the Conveying System, the safety control system required for preventing from bursting the pipe, and the experiment condition we establish.
