The flash cooler
Versatile. Proven. Powerful.
The proven design of the flash cooler is efficient, space-saving and low on maintenance. It can be used for various cooling options and is specially designed for use with fine materials. Its application areas are phosphate, lime, gypsum, sand and other ores with grain sizes of up to 2 mm.
How you benefit
This flash cooler’s key qualities are rapid cooling and highly efficient heat transfer. Another advantage is that no rotating parts are required for the cooling process so machine parts’ wear is reduced to a minimum. Even if several flash coolers are connected in series, their footprint is often smaller than that of a rotary cooler, for example. Another advantage is that no water supply and treatment system are required. Moreover, the flash cooler can also be installed behind various kilns, which significantly reduces the overall energy requirement in production.
How it works
This 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). If a flash cooler is used in combination with a cyclone, the dried material can be easily discharged onto the top of a silo so no vertical conveying equipment is needed.
The multitude of innovative process and design details makes this flash cooler a future-proof solution in terms of both mechanics and process technology.
