Triple Roller Mill - TRMS The Pharmag Triple Roller Mill TRM-S is used in the preparation of ointments, creames, pastes, doughs and related products. The TRM-S is directly connected to the UAM Motor drive which is used to adjust the speed of the rollers. The hourly production varies from 2 -12 kh/hour depending upon the consistency of the material. The rolling action is produced by three hard stainless steel rollers, which are 110 mm long, and 50 mm diameter. The two outer rollers are spring supported to eliminate the possibility of damage to the rollers or to the operating mechanism. The space between rollers is regulated by turning one thumbscrew.
