摘要

A) METHOD FOR OPERATING A SCREW EXTRUDER AND SCREW EXTRUDER USING THIS METHOD WITH A VARIABLE ROTATION SPEED, / P P B) A METHOD CHARACTERIZED IN THAT THE ROTATION SPEED IS ADJUSTED ON THE BASIS OF THE SPECIFIC ENERGY ENGAGED, BY MAINTAINING THIS ENERGY PRACTICALLY CONSTANT, AND THAT THE EXTRUDER FOR THE IMPLEMENTATION OF THE PROCESS IS CHARACTERIZED BY AN INSTALLATION22 TO MEASURE THE MOTOR POWER (N) OF THE ENGINE6, THE ENTRANCE OF THE ADJUSTING INSTALLATION18 RECEIVING A SIGNAL CORRESPONDING TO THE QUOTIENT OF THE DRIVING POWER (N) BY THE FLOW (G) AS THE ACTUAL SIZE (S) AND THE OUTPUT OF THE ADJUSTING INSTALLATION18 IS CONNECTED TO THE DRIVE MOTOR6 TO MAINTAIN CONSTANT SPECIFIC ENERGY SUBMITTED.
