slurry and to prepare rubber crumbs for finishing processes: Turns valves, starts feed pumps, and
adjusts flow-controlling and proportioning devices in supply lines to control flow of latex and of
solutions to creaming and coagulating tanks. Adjusts recirculating pumps to control overflow of
creamed latex to coagulating tank and of coagulated slurry to soap conversion tank to convert soap
to fatty acid and extract fatty acid. Regulates tank stirring mechanisms to mix contents and
controls temperatures and acid concentration by automatic recorder-controllers. Observes appearance
of crumbs through sight glasses and regulates operation of filters, shaker screens, and hammer mills
to remove moisture from and pelletize rubber crumbs for finishing processes. Records data on
