Materials Processed

Abrasives

ABRASIVES / SUPER-ABRASIVES

Standard materials are refined and processed for specialty abrasive requirements and application. Many processes such as micro-finishing, polishing, lapping and turbo-abrasive machining require or benefit from discrete particle size distributions of abrasive grains and powders. Materials such as diamond, cubic boron nitride, boron carbide, alumina, garnet and zirconia are routinely processed to customer specifications.

Minerals

MINERALS (INCLUDING, BUT NOT LIMITED TO, ZIRCONIUM OXIDE)

Naturally occurring, synthetic, precipitated, fused, and surface/property modified minerals may require size reduction, size classification, or screening to improve material or application properties. Many minerals are used as carriers, substrates or catalysts during secondary processing.

Pigment Chemical

CHEMICALS (INCLUDING, BUT NOT LIMITED TO, PIGMENTS)

Chemical processing is performed to maintain top size control, intermediate distribution requirements, fine particle control or removal, or combinations of any of these criteria. Hammer milling, jet milling, air classification and screening are typical processes utilized to obtain desired products.

Ceramic

CERAMICS

Engineered and specialty ceramic materials are processed with equipment lined with abrasion resistant materials and components in high wear areas, thus minimizing contamination. Narrow particle size distribution products can be obtained through utilization of air classification equipment.

Carbon / Graphite

CARBON / GRAPHITE

Carbon and graphite material applications are becoming more diverse with particle size typically a primary consideration for optimum application or product performance. Whether as a filtering aid or as a carrier/catalyst, fine or coarse particle removal from a broad band particle size distribution can provide desired surface area or other material properties.

Plastic and resins

PLASTICS / RESINS / COATINGS (INCLUDING, BUT NOT LIMITED TO, POLYSTYRENE, POLYESTER, AND PVC)

Soft and heat sensitive materials are processed under ambient processing conditions to obtain desired products. Sub-micron to coarse particle size distributions may be obtained by utilization of selective multiple process equipment combinations and configurations.

Test Dust

Test Dust

Powder Technology Inc. is the leading manufacturer and supplier of test dust for the filtration, automotive, heavy equipment industries, and military testing and operations. Arizona test dust is sold under a variety of names including Arizona Road Dust, Arizona Silica, AC Fine and AC Coarse Test Dusts, SAE Fine and Coarse Test Dusts, J726 Test Dusts, and most recently ISO Ultrafine, ISO Fine, ISO Medium and ISO Coarse Test Dusts.

Relevant FAQ

We are concerned about contamination from the equipment as well as from previously processed materials, what procedures are in place to prevent contamination?

  • Each machine is dismantled, blown out with compressed air, vacuumed and washed thoroughly with soap and water. Work instructions detailing our cleaning procedure are in place for each piece of equipment; they are reviewed on a regular basis.
  • All wear areas of our equipment are lined to prevent contamination or discoloration.

What materials have you processed?

  • Please go to our Materials Processed page for a list of materials processed.
  • We will not process hazardous materials or materials which are potentially explosive or flammable.

What is your processing capacity?

We can process as little as 25 pounds up to approximately 3 million pounds per year per process.
