CM Dual Drive Crackermill | Rubber Powder Production

High Volume Fine Grind System

CM Dual Drive Crackermill



CM Dual Drive™ Crackermill

The Dual Drive™ Crackermill produces more fine rubber for the tire recycling industry than all other competitive systems combined. Advanced Dual Drive™ rolls process clean rubber that is 1/4” – 5/16” [6 – 8 mm] in size, to material sizes that are 10-80 mesh [2000 – 177 microns]. The unique cutting action is produced by two large counter-rotating rolls that crack and mill the rubber to the desired size. Each roll is independently driven and operates at different speeds. Variable frequency drives allow the speed of each roll to be varied. This differential in speed between the rolls is referred to as the “Friction Ratio”. Due to the mills ability to vary its friction ratio, performance capabilities are optimized. All systems are operated by a PLC control system with feedback capabilities which allows the system to be monitored and its performance enhanced.
