Powdered materials find extremely widespread application in our daily lives, as well as in industrial and agricultural production.

Examples include:

*  Metal Powders:** Aluminum, zirconium, nickel, tungsten, tin, zinc, molybdenum, magnesium, copper, and other rare metal powders; alloy powders; and metal oxide powders, etc.

*  Non-metal Powders:** Talc, kaolin, calcium carbonate, coal dust, phosphors, brucite, calcite, wollastonite, tourmaline, diamond, barite, fluorite, zeolite, boron carbide, clay, graphite, quartz, gypsum, bentonite, diatomaceous earth, zirconium silicate, corundum, mica, titanium dioxide, etc.

*  Other Powders:** Soil, dyes, pharmaceuticals, pesticides, abrasives, coatings, flour, food additives, catalysts, plastics, papermaking materials, rubber, ceramics, cement, river sediment, etc.

Hall Flow Rate of Metal Powder

1. The measurement method of powder flowability is similar to the flow characteristics of powder in filling mold cavities, affecting production rate and the uniformity of compressed parts.

2. When internal particle friction increases, its flowability will decrease.

3. Powder humidity and moisture content will affect flowability.

4. This test is applicable to powder manufacturing plants and parts production plants.

5. Fine powders and moist powders cannot be measured.

Powder Appearance Density - Loose Packing Density Analyzer

When powder is filled into a container of known volume, apparent density = powder weight / known volume. ρ = m/v

1. Powder appearance density testing provides a standard for evaluating the physical properties of powder.

2. The determination of appearance density is similar to the relationship between the weight of powder filling a fixed volume of mold cavity during part manufacturing. The degree of this relationship lies between the measurement result and the variation in powder mass in each individual application.
