Abstract
The method for applying a dry polymer layer to particulate cores circulating as a bed in a rotor processor includes the steps of loading the cores into the processor, rotating the rotor of the processor and supplying air into the processor to create the bed, spraying the cores with a wetting agent, and supplying dry polymer powder into the bed so as to adhere onto the wetted cores and thereby build up a continuous smooth layer of polymer on the cores. The wetting agent includes a plasticizer so as to facilitate uniform layering of the micronized polymer powder.
Claims22
A method of applying a polymer layer to a circulating bed of particulate cores in a rotor chamber of the rotor chamber, comprising:
- loading the cores into a rotor processor;
- actuating airflow in the processor and rotating the processor rotor so as to circulate the cores in the chamber;
- wetting the circulating cores;
- and
- introducing dry powder polymer material into the rotor chamber so as to adhere to the wetted cores and form a layer on the cores.
