Fluid Jet Micronizers



With forty years of experience and in-depth know-how in the design and manufacture of equipment for the pharmaceutical, cosmetics and chemical industries, Tecnologia Meccanica (Italy) today can offer the most advanced Fluid Jet Micronizers systems (also known as Fluid Jet Mills) for the micronization of process powders.

Fluid Jet Micronizers provide an integrated and super-fast method of reducing the dimension of powder particles to under 5 µm in size.

This technology is extremely important in different industrial fields, particularly the pharmaceutical industry where the reduction of the active principles (the so-called API and HPAI) to such dimensions increases exponentially the characteristics of Bioavailability, Bioequivalence, and the surface area available of the product.

Tecnologia Meccanica's Fluid Jet Micronizers are capable of achieving an extremely narrow tight particle size distribution curve of d100<5 µm (100% below 5 µm) and d99<3 µm (99% below 3 µm) or even less depending on the nature of the product.

A full range of Fluid Jet Micronizers is available for all your applications, including lab machines with capacities as low as 0.5 g/hour, up to production units with throughputs of up to 1500 kg/hour.

What is Micronization Technology?

Micronization Technology is a term that refers to the complex process of producing highly-refined powders by properly reducing the size of ordinary powder particles to dimensions below 10 micrometers.

Generally, this is a complicated and rather expensive process with wide applications in various fields, particularly in the pharmaceutical industry where the production of certain drugs, such as inhalers, requires the correct particle size distribution for inhaled APIs.

How Does Micronization Technology Work?

Process powder is fed at subsonic speeds (approximately 50 m/s) into the flat cylindrical milling chamber tangentially through a Venturi system using pressurized air or nitrogen. Once inside the milling chamber, the particles are then accelerated by a series of jets around the perimeter to supersonic speeds (300 m/s) in a spiral movement.

The micronizing effect occurs when the slower incoming particles and the faster particles in the spiral path collide. While centrifugal force retains the larger particles at the periphery of the milling chamber, the smaller particles exit with the exhaust gas from the center of the chamber.
This process works at a constant temperature (endothermic) and independently with the lowest consumption of process gas of similarly sized units available on the market.

The Particle Size Distribution is controlled by adjusting two main parameters:
PRESSURE: the energy used to micronize; increased pressure increases the micronization effect
FEED RATE: the concentration of product fed into the milling chamber; the greater the feed rate, the less the micronization effect. This is due to the fact that particles must have space to achieve proper acceleration before collision occurs.
