Dynamic simulation design of centrifugal dewatering machine used in coal preparation line

Abstract

Centrifugal dewatering machine is the best solution for mechanical separation of water from solids because it can continuously dewater with high efficiency to low output moisture, while requiring little space, energy or time. Centrifugal dewatering machine is widely used in mineral processing technology, the machine has the task of separating (squeezing) water mixed in the product to reduce the product moisture. The moisture of the input product is from 18% - 28%, after passing through the dewatering device, the output moisture of the product is <= 13%. Currently, this type of machine is widely used in the coal industry, however, the it is imported from abroad with high cost and we cannot master the technology. In this study, the authors present the main factors affecting the machine during the working process and the method of integrating software in 3D design, analysis and simulation of machine dynamics, this can be the basis for scientists to refer to in the process of machine design.
