Trusted by rubber product manufacturers across multiple industries worldwide.
Mix NR, SBR, NBR, EPDM and other rubbers with carbon black, oils, and additives for uniform compound.
Small batch testing for formulation development. 4″ and 6″ models fit any lab bench.
Prepare warm, consistent compound for calenders, presses, and extruders in production lines.
Break down and re-mix recycled rubber materials into usable sheets.
Practical advantages that make a real difference on your production floor.
Chilled cast iron rolls, surface hardness HS68-75, wear-resistant and durable. Choose hollow rolls for standard rubber processing or upgrade to drilled rolls for precision temperature control within 2°C across the roll face.
LTG-H chilled cast ironSwitch friction ratio by changing external gears — convert from mastication to sheeting in under an hour. No need to swap the entire gearbox. One machine, multiple processes.
External ratio gearsEmergency stop cable across the roll · Knee-operated reverse stop · Emergency stop buttons on both sides · Safety fuse disc protects rolls from overloading. Ready for CE and UL certification requirements.
CE-ready designRotary joints feed cooling water or steam through the roll cavity for consistent temperature. Lab models come standard with electric heating. Upgrade to drilled rolls for the fastest thermal response.
Rotary joint system6-pole motors (970 rpm) deliver high torque at low speed — ideal for rubber mixing. Upgrade to IE5 permanent magnet synchronous motor with VFD drive for 15-25% energy savings. Drop-in replacement, no gearbox change needed.
15-25% energy savingsOpen structure is easy to clean between color changes. Stainless steel drip tray and stock guides come standard. All major components — rolls, gearbox, motor — are standard parts readily available. No custom parts to wait for. Ideal for small to medium factories.
