PLANT FOR PRODUCING AMMONIUM POLYPHOSPHATE |
摘要 |
A plant for producing chain-type ammonium polyphosphate from ammonium orthophosphate and phosphorus pentoxide in the presence of gaseous ammonia comprises a reactor having rotatable mixing, kneading and comminuting tools in its interior and a feed pipe for the solid starting materials, an introduction pipe for ammonia, a gas discharge pipe and a discharge line for the reaction product, all of which are flow-connected to the interior of the reactor. The discharge line of the reactor is also connected for material flow to a mixing apparatus. A discharge device, which is controlled by the power consumption of the drive motor of the reactor, is arranged in the discharge line.
