5. How does a powder maker work?

The powder maker operates on the principle of a rotating impeller forcing the material against a stationary surface. The milling action is achieved through a combination of compression, shear, and impact forces. You will now discover how a powder maker works.

Material Feeding

Gravity Feeding – Photo courtesy: aurus

The process starts with feeding the material into the powder maker that has to be turned into a powder. There are two ways to feed the material to a powder maker.

Gravity Feeding

Material is fed into the powder maker through the top of the milling chamber through an in-fee chute guided by gravity. The interlock mechanism aligns the drum with the powder maker, and the entire setup is inverted to facilitate a smooth entry of materials into the milling chamber.

Controlled Feeding:

The material feed is controlled, in some cases, to optimize the milling process and achieve the desired particle size distribution. This is done using a butterfly valve which regulates the flow of powder particles into the powder maker.

Rotor Rotation

A zone of high shear and impact forces is created as the conical rotor rotates within the milling chamber. The material is continuously drawn into this zone for size reduction. The conical shape of the rotor compresses the material against the milling chamber's walls, leading to the initial particle size reduction. The high-speed rotation of the rotor generates shearing and impact forces, further breaking down the particles into smaller sizes.

The reduced particles are propelled through a perforated sieve situated at the bottom of the powder maker. This sieve plays a vital role in achieving the desired uniform particle size. Particles of various sizes pass through the holes in the sieve. The impeller's speed contributes to altering the approach angle of particles to the screen’s surface, leading to the production of small granules.

Screening Mechanism

Powder makers include sizing screens at the bottom of the milling chamber. These screens control the final particle size by allowing particles of a certain size to exit the mill while retaining larger ones for further milling.

Discharge of Milled Material

Milled material is discharged from the cone mill through the bottom due to centrifugal force. The controlled particle size is achieved through the combination of rotor speed and screen selection.

It is essential for you to understand each step in the working principle of the powder maker for optimizing its performance and achieving the desired particle size and product quality of the powder.
