Flash cooler

The flash cooler operates according to the same principle as the shaft-type flash dryer. Ambient air is intensively mixed with the hot material in the riser pipe. The heated air can be used in other processes (e.g. as secondary air for burning processes).

Even if several flash coolers are connected in series, their footprint is often smaller than that of, for instance, a rotary cooler. Another advantage is that no water supply and treatment system is required.

If a flash cooler is used in combination with a cyclone, it is easily possible to discharge the dried material directly into the top of a silo, so that no vertical conveying equipment is needed.
