Powder and Granular Material Feeders Coal Feeder CSF

Specialized feeder for coal.

A feeder designed especially for coal, which is highly corrosive and often difficult to discharge

  1. The Circle Feeder has a solid record of use in successful coal discharge systems.
  2. Costs are reduced by limiting the specifications to focus on coal.
  3. Stable feeding, even if the material is of a rocky form particular to coal.

The Coal Feeder (CSF) is customized for application to coal, thereby aiding functionality and cost reductions.
Type 5000 is the largest model we offer.

  • Discharge test with "coal"

    The material with high corrosive wear property and of high hardness. Even for lumpy material, stable feeding is confirmed.

  • Coal Feeder

    Functions and specifications are specifically focused on coal applications, thereby enabling a lower cost than with conventional models.
