The structure, variety and application of centrifuges and centrifuges have developed rapidly, but the research on process theory calculation is backward. The knowledge acquired in the theoretical research of the Japanese civil disturbances is mainly used to explain the results of the experiments, while the performance and model selection of the pre-measured machines often depend on experience. However, the gap between the theoretical level of centrifuges and centrifuges and the actual level of machines has gradually narrowed since the 1950s. Nearly twenty or thirty years, the centrifugal filtration technique, centrifugal sedimentation and separation from the heart operation, from the understanding of the process mechanism to the quantitative calculation of the process, have T compared the comprehensive research, so the process of theoretical and computational initially formed its own system. Since the era of tianl, overseas achievements in theoretical and computational studies have been mainly apricot: 1. [UN [, A.S toHo w, M/M [" diagonal ", were b a hatred of research H.L race stages centrifugal filtration was proposed through the research firm formula of centrifugal filtration velocity, his formula be applied in the industrial centrifugal filtration calculation. (see chapter 3). M.H runi and A.S t a. R row in white, suspension of barium sulfate and a variety of materials such as starch, the work flow of liquid through the filter cake relationship, determine the liquid through the filter cake is laminar flow; put forward the liquid filled filter cake filtration process, Made a research on the various physical quantities, item by item in filtration equations is considered in the study of material conditions, the compressive stress effect on filter cake permeability small. Their research confirmed that h.g. ra c e proposed filtering equation.
