Powder cooler

Reduces the temperature, increases product quality

In order to improve general or specific product quality it is often necessary to cool the finished product directly after grinding. A powder cooler from Christian Pfeiffer provides the right solution for this task. It is suitable for all powder products, grits, and circulating material from grinding plants or similar production processes.

Technical details 

  • Indirect heat removal using the counterflow principle: The material to be cooled has no contact with the heat removal medium
  • Continuous and careful heat removal by means of an inside rotor that moves the material to be cooled upwards
  • The temperature of the input material can be reduced by 40°C to 70°C
  • If required, the cooling water can be returned to the cooling circuit using a recooling system
  • A water film cools the steel cylinder from the outside
  • Three machine sizes enable material throughputs of up to 180 t/h
  • Their compact design enables trouble-free installation in new plants, as well as easy integration into existing systems
  • Christian Pfeiffer's engineers conduct a water analysis and determine the plant components that will be required
