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.
Nine standard models covering lab-scale through mass production. Rotor speeds, motor power, and machine weights from the MIKH specification sheet:

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.
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.
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.
Tread compound, sidewall compound, and belt skim coat all require high-carbon-black loading with tight dispersion standards. MIKH-6 to MIKH-9 are commonly specified for tyre plant production lines. Modern Industries clients LG Balkrishnan & Bros Ltd. and Gulf Tyre & Rubber Holding Co. use our kneaders for compound processing.
Conveyor belt rubber requires large-volume, high-filler compound batches. MIKH-7 and MIKH-8 (100L and 125L) are standard for mining-grade and industrial belt compound production.
Cable insulation and hose compounds require highly controlled dispersion of carbon black and plasticisers. The MIKH kneader's PLC-controlled cycle and recipe management ensures compound consistency batch after batch — critical for electrical performance specifications.
Automotive seals, gaskets, and vibration-damping compounds require tight batch tolerance. The MIKH Series' real-time temperature monitoring and VFD-controlled rotor speed delivers the compound consistency required for Tier-1 and Tier-2 automotive supplier quality standards.
Commercial rubber compound houses use MIKH-4 to MIKH-6 (35L to 75L) for multi-formula production. The recipe management capability — storing different formulations in the HMI — allows rapid changeover between compounds with consistent quality.
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.

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. This significantly reduces batch time — compound cannot escape the high-shear zone and ensures homogeneous blend of rubber polymers and fine chemical ingredients.
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.
High-performance pressure ram as standard — compound stays in the high-shear zone throughout the entire batch cycle, reducing batch time and ensuring homogeneous blends. This is not an optional upgrade.
