Spiral Classifier

Spiral Classifier

Ore classification

Technical Data

  • Production capacity: 770-2800TPH
  • Screw diameter: 1500-3000mm
  • Rotation rate: 2.5~6 r/min

Advantage

  • 1 high-weir type and immersed weir type According to the spiral blade of flooding end, there are two types

  • 2 High-weir type for ore classification with flooding size between 25-120mesh The top side of spiral blade is higher than the flooding level and the center of blade is lower than flooding level

  • 3 22 models for your choose The processing capacity is dependent on the sand-return and overflow ways

  • 4 immersed weir type for ore classification with flooding size between 120-200meshThe whole spiral blade is immersed in the flooding level at the flooding end

  • Brief Introduction

    Working principle

    Based on the principle that different solid particles have different settling velocities in liquid, spiral classifier is produced. Fine particles flow on water and overflow out. Coarse and large particles settle under the tank and are pushed into ball mill again by spirals. The fine particles are discharged out through overflow pipes. The base of spiral classifier is made by steels and its body are welded by steel plates. Feeding mouth and shaft head of spiral shaft are equipped with cast-iron liner. The whole machine is wear-resistant and durable. Lifting device is classified into electric mode and hand mode.
