Bharaj Machineries - Manufacturer of Heavy Duty Rubber Mixing Mill in Mumbai, India.
Bharaj Machineries is a leading name among rubber mixing mill manufacturers in India, delivering heavy-duty, high-performance machinery engineered for consistent quality and long-term reliability. From small lab-scale operations to large industrial production lines, our rubber mixing mill range covers every requirement with precision-built components and smart automation features.
A mixing mill is an industrial machine used to blend rubber compounds with chemicals, fillers, and additives by passing the material through two counter-rotating rolls under controlled pressure and temperature. It is a fundamental piece of equipment in rubber processing, ensuring uniform dispersion of ingredients for consistent end-product quality.
Bharaj's rubber mixing machine range is designed with operator safety, energy efficiency, and minimal maintenance at its core, making it the preferred choice for manufacturers across automotive, industrial, and especially rubber sectors.
One of the standout features of Bharaj Rubber Mills is the hydraulic nip gap adjustment system. Unlike conventional mechanical systems, hydraulic nip setting offers significant operational and safety advantages:
This hydraulic system ensures the roll gap is adjusted smoothly, accurately, and safely, eliminating the risks and inefficiencies associated with manual mechanical adjustment.
Bharaj's fully automatic rubber mixing mill is engineered for power saving, delivering electricity savings of 20% to 30% compared to conventional mixing mills. Energy-efficient motors combined with a heavy-duty three-stage helical gearbox ensure maximum torque output with minimum power consumption, reducing operating costs significantly over the machine's lifespan.
Our flagship model, the BMM-22-VF-VR, is a fully featured mixing mill machine designed for high-volume rubber compounding. Key specifications include:
The BMM-18 is a robust mixing mill machine equipped with a stock blender and hydraulic stock guide, ideal for mid-volume production with enhanced mixing efficiency and operator comfort.
Designed for heavy batch compounding, the BMM-26 comes equipped with peripherally drilled rolls, the latest safety features, a hydraulic stock guide, and a pneumatic strip cutter, making it one of the most capable models in the Bharaj lineup.
Bharaj Rubber Mills are equipped with a specially designed hydraulic stock blender that assists operators in mixing rubber material with chemical powders more effectively. The stock blender delivers measurable benefits:
The speed of the stock blender can be adjusted independently of roll RPM, giving operators full control over the mixing process at every stage. This feature significantly reduces labour dependency while improving safety and output consistency.
All Bharaj mixing mill rolls are peripherally drilled to enable the best heating and cooling effect across the roll surface. This ensures precise temperature management during mixing, preventing overheating of heat-sensitive compounds and maintaining consistent batch quality throughout the production cycle.
For quality control labs, R&D centres, and small-batch compound testing, Bharaj offers a dedicated Rubber Lab Mill starting from the compact BMM-6 (6" × 13") model. The Rubber Lab Mill delivers the same engineering precision as our industrial range in a smaller footprint, ideal for formulations testing, compound development, and material analysis.
