Abstract

By varying the temperature and the flow rate of cooling water passing through rubber mill rolls and measuring the stock temperature of the rubber being milled, optimum flow rate and water temperature to be used in cooling the mill can be obtained, these corresponding to the minimum temperature difference between cooling water temperature and stock temperature. The desired stock temperature is predetermined by the rubber being processed and the optimum flow rate and water temperature may be selected to minimize the energy costs involved in running the mill.
