The mixer bowl is double-walled (heating/cooling jacket) and is heated/cooled with water or oil by a circulation thermostat. The temperature of the mixer wall is measured with an angular thermometer the sensor tip of which can be inserted through the right side of the mixer bowl. The melt temperature is registered continuously by a thermocouple screwed through the bottom of the mixer bowl. A special rotor runs in a planetary movement in the mixer bowl for compounding and mixing the material to be tested. A revolving scraper prevents the material from sticking to the mixer wall.

A certain amount of sample material is poured into the preheated mixer bowl of the planetary mixer and compounded in dry condition. After a defined period of time, the liquid (e. g. plasticizer or water) is added, and the compounding process is continued. The torque vs. time curve recorded is evaluated after the test and can be used for comparative measurements.
