  • Equipment for solid-liquid separation and drying of fine-powder slurry, and method therfor
    Patent number: 10279287
    Abstract: Prevention of contamination of a dried product, deformation of particles, and a change of particle size distribution. The system includes: a solid-liquid separator in which a processing material is supplied between a pair of endless separation filter cloths wound around an outer periphery of a separation roll, and is dehydrated by being squeezed therebetween and also by ventilation gas passing from a ventilation port formed in an outer peripheral surface of the separation roll; and a horizontal rotary dryer provided on a subsequent stage of the solid-liquid separator, wherein carrier gas is made to flow in a rotating shell of the dryer in a cocurrent manner in the same direction as a conveyance direction of the processing material.
    Type: Grant
    Filed: December 22, 2014
    Date of Patent: May 7, 2019
    Assignee: TSUKISHIMA KIKAI CO., LTD.
