MIKH Series · 5L to 150L · 7.5 HP to 200 HP at 1500 RPM · Pressure ram, hard-faced rotors, PLC & HMI automation · GIDC Umbergaon, Gujarat.
A dispersion kneader — also called an internal mixer — is a closed-chamber rubber compounding machine designed for intensive mixing and dispersion of rubber and plastic compounds under controlled temperature and pressure.
Unlike an open mixing mill where the compound is visible and manually worked, a dispersion kneader mixes inside a sealed chamber. Two specialised rotors rotate at differential speeds, applying high-intensity shear to the compound batch. A pneumatic or hydraulic pressure ram presses down on the batch, keeping the compound in the high-shear zone between the rotors throughout the mixing cycle.
Modern Industries manufactures the MIKH Series — available from 5L laboratory models through to 150L mass-production units — built for high-grade tyre compound, masterbatch, cable compound, and industrial rubber product manufacturing.

A sealed, jacketed chamber that prevents material leakage and ensures stable temperature control throughout the batch cycle. The jacket carries water (for cooling) or steam (for heating), maintaining the compound temperature within tight tolerances for consistent batch properties.
Two heavy-duty, often twisted metal blades optimised for intensive kneading and rapid dispersion of additives — particularly carbon black and other chemical powders. The rotors on all MIKH Series units are treated with hard-facing or nitriding, providing outstanding resistance to abrasive materials and ensuring long-term structural integrity with minimal maintenance in continuous production environments.
This is the key differentiator of the Modern Industries MIKH Series. The pneumatically or hydraulically operated pressure ram ensures the compound remains in the high-shear zone throughout the entire mixing cycle. This design:
After each batch cycle, the heavy-duty tilting mechanism tips the chamber forward for quick, effortless, and complete batch discharge. This reduces inter-batch time, eliminates residue sticking to chamber walls, and reduces operator effort during unloading. The tilting motor is a separate dedicated drive unit (1 HP to 7.5 HP depending on model) independent from the main mixing motor.
All MIKH Series kneaders run fully automatic operation via PLC (Programmable Logic Controller) and HMI (Human Machine Interface). Real-time digital temperature indication with efficient water cooling ensures thermal accuracy throughout the batch. Variable Frequency Drive (VFD) on the main motor provides precise rotor speed control and reduced power consumption compared to fixed-speed drives. Recipe management and data recording capabilities allow compound formulation repeatability across shifts and operators.

VFD (Variable Frequency Drive) is standard — providing precise rotor speed control and energy savings in continuous production.
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.
This is the key differentiator of the Modern Industries MIKH Series. The pneumatically or hydraulically operated pressure ram ensures the compound remains in the high-shear zone throughout the entire mixing cycle. This is not an optional upgrade.

What is a dispersion kneader machine?
A dispersion kneader (also called an internal mixer) is a closed-chamber rubber compounding machine that mixes rubber with chemicals, fillers, and plasticisers inside a sealed chamber using two counter-rotating rotors. A pressure ram keeps the compound in the high-shear zone throughout the batch cycle. It offers faster mixing, better dispersion of fillers like carbon black, and more consistent batch quality compared to an open mixing mill.
What is the difference between a Banbury mixer and a dispersion kneader?
‘Banbury mixer’ is a trade name owned by HF Mixing Group for a specific type of internal mixer. ‘Dispersion kneader’ is the generic industry term for the same class of machine. Modern Industries manufactures MIKH Series dispersion kneaders that serve as cost-effective, Indian-made alternatives to imported Banbury mixers for tyre compound, masterbatch, and rubber compound processing.
What chamber capacity dispersion kneader do I need?
Lab and pilot applications: MIKH-1 (5L) or MIKH-2 (15L). Small industrial production: MIKH-3 (25L) or MIKH-4 (35L). Standard production: MIKH-5 (55L) or MIKH-6 (75L). High-volume and heavy industrial: MIKH-7 (100L) or MIKH-8 (125L). Mass scale / mega projects: MIKH-9 (150L). Contact Modern Industries for a recommendation based on your compound batch size and cycle time target.
What is the price of a dispersion kneader machine in India?
MIKH Series kneader prices depend on chamber capacity and automation level. Entry-level MIKH-1 (5L, 7.5 HP) starts from approximately ₹7.75 Lakhs. Mid-range industrial models (MIKH-4 to MIKH-6, 35L–75L) range from ₹20–60 Lakhs. Large capacity MIKH-7 to MIKH-9 (100L–150L) are priced on specification. Contact Modern Industries for a quotation.
What motor power does a dispersion kneader use?
MIKH Series motors range from 7.5 HP (MIKH-1, 5L) to 200 HP (MIKH-9, 150L), all running at 1500 RPM. A separate tilting motor (1 HP to 7.5 HP) handles the hydraulic batch discharge mechanism. VFD (Variable Frequency Drive) is standard — providing precise rotor speed control and energy savings in continuous production.
What is the pressure ram in a dispersion kneader?
The pressure ram (also called the pressure lid) is a pneumatically or hydraulically operated component that pushes down on the rubber batch inside the mixing chamber. It ensures the compound remains in the high-shear zone between the rotors throughout the entire mixing cycle. This significantly reduces batch time and ensures homogeneous dispersion of rubber polymers and fine chemical ingredients. It is standard on all Modern Industries MIKH Series kneaders.
Can a dispersion kneader process all rubber types?
Yes. Modern Industries MIKH Series kneaders are designed to process all standard rubber types including Natural Rubber (NR), SBR, NBR, EPDM, CR (Neoprene), IIR (Butyl), and silicone rubber. The rotor configuration and chamber size are selected based on the primary compound type and production requirement.
What is hard-facing and nitriding on dispersion kneader parts?
Yes. Modern Industries MIKH Series kneaders are designed to process all standard rubber types including Natural Rubber (NR), SBR, NBR, EPDM, CR (Neoprene), IIR (Butyl), and silicone rubber. The rotor configuration and chamber size are selected based on the primary compound type and production requirement.
What is the delivery time for a dispersion kneader machine?
Standard MIKH Series models (MIKH-1 to MIKH-5) typically ship within 8–12 weeks from order confirmation and advance payment. Larger models (MIKH-6 to MIKH-9) and custom configurations require 12–16 weeks. Export orders include additional time for documentation, seaworthy packing, and freight arrangement.
