 What is Fluid Energy Mill? Working Principle, Construction, Application, Advantages, Disadvantages

FLUID ENERGY MILL

Fluid Energy Mill is a type of size reduction equipment that is commonly used in the pharmaceutical, chemical, and food industries.

It is also known as a jet mill or a fluidized-bed mill.

It operates on the principle of using a stream of compressed air or gas to create a high-velocity jet of particles that collide with each other and reduce in size.

Construction:

A fluid energy mill typically consists of a cylindrical chamber, a feed inlet, a compressed air inlet, a grinding chamber, and an exhaust port.

The cylindrical chamber is lined with a porous material to allow the air to enter and exit the chamber.

The feed material is introduced into the chamber through the feed inlet, and the compressed air is introduced through the compressed air inlet.

The high-velocity jet of air carries the particles around the grinding chamber and causes them to collide with each other, resulting in size reduction.

Working Principle:

 

The working principle of the fluid energy mill involves the use of compressed air or gas to create a high-velocity jet of particles that collide with each other and reduce in size.

The feed material is introduced into the grinding chamber, where it is mixed with the high-velocity jet of air.

The air carries the particles around the grinding chamber and causes them to collide with each other, resulting in size reduction.

The reduced particles are then carried out of the mill through the exhaust port.

ADVANTAGES

High grinding efficiency

Narrow particle size distribution

Low heat generation during milling

Can handle a wide range of materials

No contamination of product

DISADVANTAGES

High energy consumption

High operating costs

Can only handle materials that are dry or have low moisture content

Limited to the production of fine particles

Require a large amount of compressed air

APPLICATIONS

Fluid energy mills are commonly used in the pharmaceutical, chemical, and food industries for size reduction of various materials.

They are also used for grinding and pulverizing materials that are difficult to grind using traditional milling methods.

                                                                        HAMMER MILL   Method of size reduction: Impact  Construction and working principle: Hammer mill consists of a steel casing, enclosing a central shaft to which four or more hammers are attached. These are mounted with swivel joints, so that the hammers swing out to a radial position when the shaft is rotated. The lower part of the casing consists of screen through which materials can escape, when sufficiently size reduced. The material is collected in a container placed below the screen. The screen can be changed according to the particle size required. According to the purpose of operation the hammers may be square-faced, tapered to a cutting form or have a stepped-form. The interior of the casing m...

NEW ERA OF DRUG PRODUCT: OPPORTUNITIES AND CHALLENGES

  NEW ERA OF DRUG PRODUCT: OPPORTUNITIES AND CHALLENGES Introduction One of the key determinants of a nation's level of development is its health care system, which also reveals the direction in which a nation is developing. Pharmaceutical businesses continuously strive to improve the standard of healthcare for people. One of the key elements of the administration of health care and its costs is pharmaceutical products or medications. An individual's spending for managing their health is rising as a result of changes in lifestyle and an increase in personal income. According to research, the cost of pharmaceutical items has grown more rapidly than the cost of all worldwide health care combined. The pharmaceutical industry not only benefits the nation's health care system but also its economy through fostering job growth, fostering ancillary sectors, generating export revenue, boosting GDP, and other factors. Thus, the expansion of a nation's pharmaceutic...
