Toll sieving also referred to as dry powder sifting or a dry powder screening service (particle processing), is essentially a turn-key solution which a powder manufacturer or powder material importer will drop ship all of their raw feed materials (raw powder) to us for processing. Elcan takes the powdered material and classifies it through our high-performance powder sieving machines to deliver our clients their desired particle size specifications.

Toll sieving or air classifying powders is essentially the process in which companies have any particular powder and they need the powder sized or classified into a particular size specification. Generally speaking, companies buy raw powder from a powder supplier or manufacturer and then have it shipped to a toll processor like Elcan and have them screen the powder into multiple size ranges so that they can create different products and end use applications for their clients. Other times, companies have good powder and just need to screen out some contamination that got inside their powder during the manufacturing process so instead of scraping the material or shipping it back to the manufacturer, companies send it to a toller and have them screen out the contaminated particles and return the powder to a pure and usable state.
The benefits of having Elcan as a toll processing partner is that Elcan Industries is the only company in the world with the capabilities of screening powders down to very fine sizes such as 10um and 1um respectively, on an industrial scale utilizing its proprietary screening technology the Hi-Sifter. Elcan Industries has a very distinct advantage over companies that strictly sell equipment because we actually run the very same equipment we sell. Furthermore, Elcan manufactures and customizes the sieving equipment to offer catered processing solutions for clients depending on their objectives, powder material type, density and other important criteria. Our sieving equipment gives Elcan and its customers the ability to process powdered materials at virtually any particle size range they require down to as fine as 10um on a large commercial scale. Companies that utilize our contract sieving services experience high throughput rates, yields and over 95% efficiencies all without having to run multiple passes on material.
In its contract manufacturing facility, Elcan offers particle separation services for companies that are struggling with particle contamination issues, screen mesh blinding, low feed rates, low yields and other issues associated with mediocre screening equipment / services. Elcans particle processing capabilities are often paired with our contract packaging services, blending, particle size analysis and magnetic separation to provide full manufacturing capacity to our customers.

What Is Powder Sieve Analysis?
Powder sieve analysis is a testing method designed to separate a granular material into different groups based on the sizes of the particles that comprise the sample.
This method involves
The results of a powder sieve analysis are dependent on the weight of powder left on each sieve upon completion of testing.
Why Is Powder Sieve Analysis Used?
Powder sieve analysis is a beneficial examination that can reveal crucial information about the properties of a powdered metal sample. Powder sieve analysis is used because it incorporates a repetitive procedure with simple equipment to provide a test for purposes of quality control in particle size distribution (gradation) of a material.

What Are the Uses of Powder Sieve Analysis?
Powder Sieve Analysis Evaluates Particle Size (Gradation)
Powder sieve analysis is utilized in order to evaluate the particle size distribution, or gradation, of a metal powder. This is a crucial characteristic of powdered metal materials.
The Gradation of a Sample Can Reveal Information Pertaining to:
The gradation of a powdered metal sample aids in the analysis of the quality of said sample.
Astm B214 Provides a Method of Dry Powder Analysis That Is Both Precise and Reproducible
The equipment for operation possess the perks of versatility and simplicity
In order to conduct a powder sieve analysis, ASTM B214 calls for a sample size that is dependent on the density of the powder. The majority of metal powders have a density greater than 1.5 g/cm3, and will thus require a sample of 150 g.
ASTM B214 Is Conducted via the Following Steps:
There are a variety of characteristics and properties of metal powders that are used in powder sieve analysis. Sieve analysis can be performed on a wide range of organic and nonorganic granular materials including sands, clays, coals, crushed rock, granite, soil, manufactured powders (irons, iron and copper, nickel, zinc, tin, lead), seeds, and grains.
Standardized Testing Solutions for Powder Sieve Analysis
Powder sieve analysis is a beneficial examination that can reveal crucial information about the properties of a powdered metal sample. The implementation of a standardized test like ASTM B214 at the time of testing ensures a simple and replicable procedure for purposes of quality control. Each time the test is performed, the samples will be identically aggravated for an ideal amount of time. The motion of the mechanized sieve enables complete transfer of distinctly sized particles through the appropriate sieves. The information gained from testing to ASTM B214 provides reliable methods for quality control of the raw products that are used in the powder metals and additive manufacturing fields.
