Product Description
Jet Mill:
Applications:
Jet Mills are widely used in the manufacture of drugs and pharmaceuticals, organic and inorganic pigments, optical brighteners, fluorescent pigments, food colour synthetic dyes, metal (except malleable metals) carbides & borides, tobacco, herbicides and pesticides, ceramic glasses, alumina, feldspar, frit, kaolin, mullite, electronic grade materials such as materials required for semiconductors, phosphors, photo-electronic, high temperature critical materials, rocket solid fuels etc.
Working Principle:
Jet Milling is a concept of feeding of the powder particles into a flat circular milling chamber and subjecting the same tangentially with pressurized air or nitrogen through a venturi. The powder particles are accelerated in a spiral movement inside the milling chamber by number of angular holes in a ring and placed around the periphery of the chamber.
The heat sensitive and low melting point materials are easily micronized. The micronization takes place due to the collision between the incoming particles and the particles, which are already accelerated into the spiral path. The larger particles of the product get retained at the periphery of the chamber by centrifugal force and the smaller particles exit with the exhaust air from the central portion of the chamber.
The material can be milled to an average particles size of 0.2 to 5 micron or coarse ground to 400 mesh depending upon characteristics of the product
Particle Separator:
The particle size distribution is controlled by adjusting pressure and feed rate. The particles are trapped by specially designed cyclonic separator and finger-bag made of non-woven PTFE coated cloth without risk of fibre contamination. The dust separator and collectors are cylindrical and are having sanitary clamp for quick accessible connections. The system is without reverse jet so as to save air / gas consumption. With the finger-bag shaking arrangement, the bag is automatically cleaned with a set time interval.
We also provide high-efficiency, dust separator combining inertial and static effects, with membrane filter cartridges, reverse-pulse, automatic cleaning and final safety HWPA filter that exhausts clean air to the atmosphere.
Jet Mill is mounted on an ergonomically designed portable stand.
Advantages:
The micronizing of the powder improves absorption capacity of the drugs in the human body. This also results in new and unusual chemical and physical properties relating to suspendability, solid-state reaction rate, texture, colour, absorption etc.
The surface area achieves increase in potency of drugs, which reduces the dosage of the drugs. Product of 30 mesh size when jet milled to 5 micron, has more than 160,000 particles & surface area more than 115 times. This results into faster reaction time for chemicals, faster ignition time in the case of solid fuels of rockets. The Jet Milled pesticides & herbicides cover much more surface area using less of the active ingredients, thus reducing the cost. The polishing powders used for polishing the lenses, computer hard disc or in toothpaste are required to be a narrow particle size distribution for maximum productivity. The abrasives used in these polishing powders are very precisely milled.
Any cosmetic product requiring silky smoothness in application can be achieved in Jet Mill. The reflectivity of light occurs when the particle size of the pigment approaches a precise relationship to the wavelength of visible light. Therefore by controlling the particle size, the product quality & its brilliance can be ascertained.

Our Company:
It all began in the year 2001. Like an energetic toddler, we first learnt to stand erect, and then to walk steadily.
Now it`s time to run and try to beat the pace of the world.
Built on an area of 10,000 sq ft, the Promas office and factory are located in a `state-of-the-art` facility at Navi Mumbai in the MIDC (Maharashtra Industrial Development Corporation (MIDC) area.
ISO 9001 certified, Promas is a name to reckon with for design and manufacturing of a wide range of process equipment and systems. These are built in varying sizes,that can be customized right from Kilo Lab model to Plant Scale, in compliance with stringent cGMP / USFDA standards, which carry CE markings, too. It is this never-ending quest for technical innovation in the field and providing best quality products, supported by prompt service technicians that`s earned us the stature we enjoy today; little wonder then, our clientele comprises some of the world`s leading Pharmaceutical, Chemicals, Cosmetics, Food Products and Bulk Drug manufacturers.
