Co-current drum intended for drying sand / lime / dolomite or other raw material. The dryer drum can also be used for ash / slag or recycled materials. The drum is mounted with a combined oil / LPG burner. The drum and filter are controlled by a KVM controller developed for each drying process.

The flue gas pipe of the drying plant for the filter is insulated, as is the coarse separator and collecting funnel for fine filler.

This is done to avoid moisture, so it is possible to produce with very low flue gas temperatures.
