本文探讨的负压比重精选机是20世纪70年代,由国内生产厂家参照瑞士布勒公司的主机,消化吸收改进设计而成,沿用至今已有较长的时间。该精选机是根据颗粒状物料在流态化过程中会产生颗粒与密度偏析现象的原理,通过调整风压,振幅等技术参数,使物料与物料之间相互置换产生分层,比重大的向下沉降,比重小的
This article explores the proportion of negative pressure selection machine is 70 years of the 20th century, the domestic manufacturers refer to the host of the Swiss company Buhler, digestion and absorption of improved design, has been in use for a long time. The sorting machine is based on the granular material in the process of fluidization will have the phenomenon of segregation of particles and density principle, by adjusting the wind pressure, amplitude and other technical parameters, the material and material mutual replacement between the stratification, the proportion of major Subsidence, the proportion of small
