Powder Production Line

Powder Production Line

Powder metallurgy is the technology (and sometimes, even the art) of producing metallic materials and components from a predominantly metallic powder instead of via the conventional ingot metallurgy route. PM products are generally divided into two groups.

The powder manufacturing process involves several steps and requires specialized equipment to function. Adding an intelligent element to this machinery could enable self-regulation to ensure that standards are met.

Production of the Powder

Powder metallurgy is an ancient method of producing shapes and designs from ferrous and nonferrous metals. Although the process has its drawbacks, technological advances have streamlined it into a low cost means of producing precision intricate parts. It also has the advantage of allowing for flexible manufacturing without compromising quality.

Powder soap production is accomplished in a variety Powder Production Line of ways, but the blender technique is the most common. It is the most affordable way for small businesses to get into the business of detergent manufacture. The other three techniques that are used in powder soap production include agglomeration, spray drying, and dry mixing. Each one has its own unique advantages and disadvantages.

A blender can handle massive amounts of combined ingredients, but agglomeration is a more precise method. It allows the production of smaller pieces that can fit into a specific size and shape, which is a big advantage for manufacturers who are making a large number of detergents for a particular market or industry.

Milk powder processing line includes raw milk acceptance system, milk standardization tank, homogenizer, sterilization machine, milk skimming (to produce skimmed milk powder), vacuum concentration, sugar preparation, spray drying machine and sieving. It can produce full-fat sugared milk, skimmed milk powder and flavored milk powder as per customer’s requirements. It’s safe, convenient, easy to operate and can be customized based on raw material, drying technic, processing capacity and way of packing.

Mixing and Blending

The properties of a powdered metal are determined by the process used to produce it. The primary method is melt atomization which breaks liquid metal into tiny droplets that cool and solidify into minute particles, but other processes can also create metal powder. Once it has been produced, the powder must be mixed and blended with other ingredients to form a homogenous mixture. Mixing and blending are very different operations; mixing involves thoroughly combining dissimilar materials to achieve a uniform mixture, while blending combines powders of the same chemical composition into a single mass that cannot be separated back into its original components.

In the case of powders, this can be a very difficult operation since the physical characteristics of these materials vary widely. They can be influenced by their chemistry, size distribution and internal structures; the ability to mix them efficiently depends on these factors as well as their shear behaviour.

To this end, mixer and blender manufacturers have developed a large variety of mixer and blending equipment to address these issues. Double cone and Vee blenders tumble their contents over and over, while rotary drum mixers, fountain blenders and low speed ribbon mixers all offer a range of options to suit the application. Other equipment such as sifters and shakers separate products by size or density, and classifiers reverse the process to enable products to be divided into groups based on their chemistry.


Following the blending and mixing of the powder, it is compacted into a die or mold. This process reduces potential voids and increases the density of the final product. This is called “compaction”. Depending on the type of metal used, compacting pressure ranges from 80 to 1600 MPa. The resulting form is known as a green compact, indicating that it was made by compaction.

The powder metal manufacturing process is particularly well suited to producing components with complex geometries and a high level of mechanical properties that cannot be produced through the ingot route. filling machinery This is especially true for high-performance, nickel-based superalloy turbine discs that are used in air and land-based gas turbines. For these types of applications, a PM-based process route typically incorporates Hot Isostatic Pressing (HIP).

In HIP, spherical metal powder is mixed with plastic or wax as a binder and then injected into a mold. The mold is then heated and compressed under controlled conditions to form a near solid, spherical part with a very complex geometry. Once the green part is formed, it can be heated to remove the binding agent in a process called de-bindering and then subjected to sintering. This produces a finished part with the correct shape and full density that matches the as-wrought properties of the original material. Another type of PM process that does not use binders is electric current assisted sintering (ECAS). It uses an electrical current to increase the density of the powder without a heat cycle, thus reducing production time.


Powder production lines typically use agglomeration to combine dry components into a form that can be packaged. Ingredients are combined in a machine called a tumbling or ribbon blender, then blasted with hot air from above, which creates an exothermic reaction. The resulting slurry is then dried with more hot air. This process is used for surfactants, optical brighteners, fabric softeners, enzymes, bleaches and compounds, synthetic perfumes and fragrances and other chemicals.

The slurry is sent into a storage hopper. A main unit, inverter classifier and cyclone collector send it to the first dial evenly by vibration feeder. The first dial is a set of rotating rollers, each with a different number of teeth, which are driven by the main machine through reducer and gears.

According to Stable Micro Systems, working with powders is challenging because they can compact under their own weight during storage, restricting flow and resulting in blockages that require time-consuming cleanup or lost product. The company’s Powder Vertical Shear Rig allows manufacturers to understand and predict powder flow behavior, minimizing downtime caused by unforeseen blockages. It’s designed to test powders for abrasiveness, flowability and solubility. It can also detect dynamic weight online and automatically reject waste. The machine can complete bag forming, printing/embossing, sealing, punching, cutting and counting, and can also be equipped with conveyor for automatic feeding and finishing.
