Trommel Washing Drum
A trommel washing drum is an industrial washing system that removes clay, dust and fine particles from ores and aggregates, cleaning the material and preparing it for the next processing stages.
Mining Machinery
Industrial spiral classifier solutions that separate materials precisely by particle size after crushing and grinding, with low energy consumption and easy maintenance.



KRIOS Classifier Systems are industrial equipment used in mining and industrial mineral processing plants to separate the material obtained after crushing and grinding according to particle size.
Their spiral or screw design allows coarse and fine particles carried in water to be classified in a controlled way. Robust construction, low energy consumption and easy maintenance support efficiency in production processes.
Spiral classifiers carry out classification by making use of the settling velocities of particles in water.
Coarse, heavy particles settle at the bottom of the tank and are carried to the discharge point by the rotating spiral. Finer particles leave with the water flow through the overflow.
This method allows controlled material separation, particularly in ore preparation and grinding circuits.
KRIOS Engineering provides engineering solutions for classifier systems suited to different production capacities and material properties.
