A rubber mixing mill is an open-type, two-roll machine used in the rubber and plastic industries to process raw materials by plasticising, mixing, refining, and sheeting. It mixes rubber polymers with additives — oils, fillers, and vulcanising agents — by passing them between two horizontal rollers rotating at different speeds in opposite directions.
All Modern Industries mixing mills are supplied in the AFB (Automatic Friction Brake) series. Eight standard models — from lab and small-batch production through to large tyre plant and export-grade heavy industrial units
| Model Name | Roll Size Dimension | Motor Parameters (HP / RPM) | Batch Capacity | Optimal Application Profile |
|---|---|---|---|---|
| M1 – AFB | 10" × 24" | 15 / 1000 | 8 – 10 kg | Laboratory Testing & Small Batch Qualification |
| M2 – AFB | 12" × 30" | 25 / 1000 | 18 – 20 kg | Small Batch / Specialty Material Runs |
| M3 – AFB | 14" × 36" | 40 / 1000 | 28 – 30 kg | Mid-Scale Industrial Lines |
| M4 – AFB | 16" × 42" | 60 / 1000 | 38 – 40 kg | Mid-Scale Continuous Production |
| M5 – AFB | 18" × 48" | 75 / 1000 | 45 – 50 kg | General Industrial Rubber Goods Factory |
| M6 – AFB | 22" × 60" | 120 / 1000 | 65 – 80 kg | High-Volume Manufacturing Facilities |
| M7 – AFB | 26" × 84" | 215 / 1000 | 90 – 105 kg | Heavy Industrial Output |
| M8 – AFB | 30" × 100" | 300 / 1000 | 125 – 200 kg | Large-Scale Automotive / Masterbatch Plant / Tyre Facilities |
Custom roll sizes available on request. Motor HP confirmed against compound viscosity and production duty cycle at time of order.
Modern Industries AFB mixing mills are equipped with a specially designed hydraulic stock blender — an integrated attachment that works alongside the rolls during the mixing cycle. This is a key differentiator from standard mixing mills available in the market.
Tread compound, sidewall compound, bead filler mixing
Sheeting for industrial and commercial rubber floor tiles
Rubber compound preparation for moulded and cut gaskets
Specialised rubber sheeting for medical and healthcare applications
Rubber-coated fabric for industrial and protective applications
Sole compound for slippers, sandals, and safety footwear
Compound preparation before calendering
Seals, hoses, anti-vibration mounts
Raw rubber (bale-cut) fed between the rolls without additives. Rolls break down polymer chains, reducing viscosity and preparing the rubber to accept additives.
With rubber sheeting on the front roll — activators first, then fillers (carbon black, silica), then curatives (sulphur, accelerators) last. Order of addition is critical for dispersion quality and cure rate.
The hydraulic stock blender assists the operator in folding and re-feeding the compound through the nip. 8–15 passes until homogeneous dispersion is confirmed.
Finished compound sheeted off at required thickness (set by nip), cut, labelled, cooled, and sent to moulding, extrusion, or calendering.
Standard on all AFB models to reduce operator labor, lower compound temperatures, and accelerate mixing rates. Competitors rarely offer this out-of-the-box.
The core AFB design has been field-tested and refined over five decades. Heavy-duty construction keeps machines built in 2005 running flawlessly today.
Operator protection is non-negotiable. Our comprehensive safety package ships fully integrated on every single machine assembly, never as a premium upgrade.
Delivers high-precision roller speed variations and responsive nip gap controls, guaranteeing strict, repeatable compound consistency across every batch.
Complete operational peace of mind with on-site engineering maintenance, remote diagnostics across 19+ export markets, and lifelong OEM spare parts availability.
