High performance heavy duty AFB models ranging from 10"×24" to 30"×100". Engineered with custom 15 HP to 300 HP motors at 1000 RPM. Over 50 Years of manufacturing excellence out of GIDC Umbergaon, Gujarat.
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.
Frame, two horizontal rolls (chilled cast iron), driving gear, lubrication system, roller nip adjustment device, and safety brakes
Raw rubber is fed into the nip (gap) between the rollers, mixed, then manually or automatically cut and folded back for consistent mixture quality
Rolls are heated or cooled (via water) to manage compound temperature — preventing premature vulcanisation
Equipped with emergency brake systems including rod-operated and knee-operated stops for operator safety

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.
Reduces Labor Effort
Assists operators dynamically in mixing heavy rubber material with compound chemical powders.
Safer Operation Standards
Keeps the operator’s hands safely isolated away from the critical roll nip entry zones during mixing operations.
Optimized Temperature Levels
Lowers the overall batch temperature continuously to eliminate premature compound scorching.
Independent Speed Adjustments
Stock blender feed rates can be completely manipulated independently regardless of the main roll RPM.
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.
“MODERN mixing mills are equipped with a specially designed hydraulic stock blender to assist the operator in mixing the rubber material and chemical powder. It reduces the labor indulgence, provides safer working conditions, lowering the material temperature and speeding the mixing rate of the compounds.
The speed of the stock blender can be changed as per requirement irrespective of the roll rpm.”
What is a rubber mixing mill?
A rubber mixing mill is an open-type two-roll machine used to process rubber by plasticising, mixing, refining, and sheeting. Raw rubber and additives are passed repeatedly between two counter-rotating, temperature-controlled rolls. The nip gap between the rolls is adjusted to control compound dispersion and sheet thickness. It is the foundational machine in every rubber compounding operation.
What is the price of a rubber mixing mill in India?
Rubber mixing mill prices vary by model. M1-AFB (10″×24″, 15 HP) is entry-level — contact us for pricing. Industrial M5-AFB to M7-AFB models range from approximately ₹8 to ₹40+ Lakhs. Heavy industrial M8-AFB (30″×100″, 300 HP) is priced on request. All pricing is based on confirmed specifications — contact Modern Industries for a quotation.
What is the hydraulic stock blender on Modern Industries mixing mills?
The hydraulic stock blender is a specially designed attachment on all Modern Industries AFB mixing mills. It assists the operator in mixing rubber with chemical powders, reduces manual labour, lowers compound temperature during mixing (preventing premature vulcanisation), and speeds mixing rate. The blender speed is independently adjustable — separate from roll RPM — allowing precise control without stopping the mill.
What roll sizes are available for rubber mixing mills?
Modern Industries manufactures AFB mixing mills in eight standard models from 10″×24″ (M1-AFB) to 30″×100″ (M8-AFB). Models: M1 (10″×24″), M2 (12″×30″), M3 (14″×36″), M4 (16″×42″), M5 (18″×48″), M6 (22″×60″), M7 (26″×84″), M8 (30″×100″). Custom roll sizes available on request.
What motor power (HP) do rubber mixing mills use?
Modern Industries AFB mixing mills range from 15 HP (M1-AFB, 10″×24″) to 300 HP (M8-AFB, 30″×100″). All motors run at 1000 RPM. Mid-range models: M3 = 40 HP, M5 = 75 HP, M6 = 120 HP. Actual motor specification is confirmed against compound viscosity and production duty cycle at the time of order.
What is the difference between a mixing mill and a dispersion kneader?
A mixing mill is an open two-roll machine — visible rolls, operator-controlled compound addition, suitable for general compounding, mastication, and batch processing. A dispersion kneader is a closed internal mixer — faster per batch, better dispersion for high-filler compounds, and less operator intervention. Kneaders are preferred for high-volume tyre compound; mixing mills for versatility, smaller batches, and lower capital cost.
What safety features are standard on Modern Industries mixing mills?
All AFB mixing mills include: emergency stop push button with limit switch, electric/hydraulic thrustor brake, knee and foot brake system, cradle bar, safety cable and chest guard, HMI-based alerts, audible buzzer alarm, and heavy-duty safety grills and gear guards. All safety features are standard on every unit — not optional upgrades.
What industries use rubber mixing mills?
Mixing mills are used across tyre component manufacturing, rubber flooring production, gasket making, hospital rubber sheets, coated textile manufacturing, footwear sole compounding, conveyor belt compound preparation, and automotive rubber parts. The M-series covers all scales — from small footwear and gasket factories to large tyre plants.
What is the delivery time for a rubber mixing mill?
Standard AFB models (M1–M5) ship within 6–10 weeks from order confirmation and advance payment. Larger models (M6–M8) and custom configurations require 10–14 weeks. Export orders include additional time for seaworthy packing and export documentation. Timelines are confirmed in writing at order acceptance.
Do you export rubber mixing mills?
Yes. Modern Industries exports AFB mixing mills to 19+ countries including UAE, Bangladesh, Vietnam, Indonesia, South Africa, Saudi Arabia, Oman, Egypt, Nepal, and Sri Lanka. Full export documentation, seaworthy crating, and shipment via Hazira, JNPT, or Mundra ports are handled by our team. CIF or FOB terms available.
