Reflux Cooler for granular and free flowing bulk materials

is especially suitable for granular and free flowing bulk materials, as it is a contact cooler. The material to be cooled graining < 1.5 mm slowly flows along the water cooled cooling faces in counter current fashion. Water does not of course come into contact with the bulk material. The special design of the contact areas between the cooling segments and the cooling spirals ensures that a high degree of heat exchange is achieved. A constant temperature of the cooled bulk material is achieved by automatically controlling the flow of cooling water. The reflux cooler is compact in design,...

Technical data: Auto regulating accuracy: z. ± 3 K Temp, of inflowing water: Normally 10° below the required temp, of the outflowing bulk material Water pressure: see diagram The following factors effectively reduce the cooling capacity of the reflux cooler: too little cooling water; too warm cooling water; humid bulk material blocks up the cooling segments; impurities in the bulk material block up the sieve; sediments in the water reduce the trans- double stage cooling empty filled empty filled The size of the cooling face of the reflux cooler is dependent on a number of with the bulk...
