Working Principle of GMP Multi Mill

The GMP Multi Mill operates on the principle of variable force swing beaters with both knife and impact edges rotating at high speed within a selected perforated screen. This enables efficient size reduction, granulation, pulverization, mixing, shredding, and chopping of a wide range of wet and dry materials.

Step-by-Step Process:

Material Feeding The raw material is fed through the stainless steel hopper (with slide plate for feed rate control) into the milling/processing chamber.

Size Reduction Inside the chamber, a high-speed rotor fitted with 12 beaters (knife/impact edges) and 2 scrapper blades rotates rapidly (typically 750 to 3000 RPM). The swinging beaters subject the material to impact, shearing, cutting, and attrition forces.
- Knife edges are used for cutting and slicing.
- Impact edges (hammer action) are used for crushing and pulverizing.

Screening & Particle Separation The processed material is thrown towards the periphery and passes through the interchangeable perforated screen (available in sizes from 0.5 mm to 12 mm). Only particles that reach the desired size exit the screen radially and tangentially. Oversized particles continue to be processed until they pass through.

Discharge The finely reduced material is collected in a container or bin placed below the discharge hopper.

Key Features of GMP Multi Mill

Operation: Utilizes variable force swing beaters with knife and impact edges rotating within a cylindrical screen to control particle size, producing a narrow particle size distribution with minimal heat generation, ideal for heat-sensitive materials.

Material: All product-contact parts are made of stainless steel for corrosion resistance and easy sterilization, preventing cross-contamination.

Design: Compact, noiseless, low-maintenance, with safety interlocks, emergency stops, and castor wheels for mobility. Easy disassembly ensures thorough cleaning.

Capacity: Output ranges from 50-200 kg/hour, depending on the model, with screen sizes from 0.5-12 mm hole diameters.

FAQ for GMP Multi Mill

What is a GMP Multi Mill and what is it used for?

The GMP Multi Mill is a versatile, high-speed size reduction machine designed for granulating, pulverizing, mixing, shredding, and chopping of both wet and dry materials. It is widely used in the Pharmaceutical, Ayurvedic, Herbal, Nutraceutical, Biotech, and Cosmetic industries for achieving uniform particle size distribution of APIs, excipients, granules, and herbal powders. It helps improve flowability, dissolution rate, and blend uniformity while meeting strict cGMP, US-FDA, and WHO-GMP standards.

How does the GMP Multi Mill work?

Material is fed through the stainless steel hopper into the milling chamber. A high-speed rotor with swing-type beaters (knife and impact edges) and scraper blades subjects the material to impact, shearing, cutting, and attrition forces. The processed particles pass through interchangeable perforated screens (0.5 mm to 12 mm). Oversized particles continue to be milled until they achieve the desired size. The rotor direction is reversible for optimized performance.

What are the key advantages of the GMP Multi Mill?

High output with excellent process uniformity
Versatile for wet and dry granulation with minimal heat generation
Easy cleaning and quick product changeover
Compact, portable design on castor wheels
Full cGMP compliance with SS 304/SS 316 contact parts
Reversible blade rotation and variable speed for precise control
Low maintenance and suitable for heat-sensitive materials.

What capacities and models are available for the GMP Multi Mill?

We offer three main models:

MM-100: Up to 100 kg/hour (1 HP)
MM-200: Up to 200 kg/hour (3 HP)
MM-500: Up to 500 kg/hour (5 HP)

Rotor speeds range from 750 to 3000 RPM. Lab-scale to production-scale models are available with customizable options.

How easy is it to clean and maintain the GMP Multi Mill?

The machine is designed for easy disassembly — all contact parts (hopper, screen, beaters, and discharge) can be quickly removed without tools. Mirror-polished stainless steel surfaces and the absence of dead corners minimize residue. This supports fast cleaning, sterilization, and frequent product changeovers while ensuring full GMP compliance.
