The paste thickener mainly consists of the tank, bridge, drive unit, feed well, rake frame unit, control system, testing instruments, and underflow circulation system Slurry first enters the thickener feed component, where dilution and dynamic mixing with flocculant occurs. After fine mineral particles react with flocculant to form flocs, they enter the thickener tank and undergo free settling, hindered settling, and compression settling processes, ultimately forming high-concentration slurry with underflow concentration typically between 60-70%.

  Drive unit: Drive system typically uses motor-gear reducer configuration, featuring high torque and low speed.
• 02

  
  Feed well: Features slurry dilution function, available in active or passive modes. Active dilution involves an opening in the feed well that uses specific gravity differences between slurry and supernatant to allow clear water entry, saving energy. Passive dilution installs a dilution pump in the feed well to pump supernatant into it, allowing adjustable dilution water volume.

  Underflow circulation system: Features three functions - low-level circulation, high-level circulation, and underflow discharge.
