Coagulation operator


Coagulation operators control machines to coagulate synthetic rubber latex into rubber crumb slurry. They prepare these rubber crumbs for finishing processes. Coagulation operators examine the appearance of the crumbs and adjust the operation of filters, shaker screens and hammer mills to remove moisture from the rubber crumbs.
