<p>The motor energy, as indicated by a meter, and the pressure stamp setting in the mixture chamber are monitored by a pressure control system which reduces mixing chamber press. should motor energy levels rise. Similarly a thermostatic temp. control operates a cooling circuit should friction heat exceed limits. The purpose is to prevent soot additives from lumping on being fed into the blend and to a prevent motor and seal damage from press. surges during mixing.</p> |
