Internal testing instrument: digital caliper accuracy0.01mm

After the upgrade of the Skott volumetric density tester, the following functions have been added: in addition to configuring the positioning angle, this product is equipped with a leveling device for adjusting the balance, reducing the influence of external environment on the measurement results; The measuring cup has a positioning device to ensure that the center of the funnel and the measuring cup are in a straight line.The square fabric box is surrounded by4Fix the block acrylic board to prevent the sample from splashing out during testing;This is the basis for our companyGB/T 1479.2-2011Metal powder Determination of loose packing density 2Part: Scott capacity meter method replaces national standardGB5060—85A powder bulk density testing device developed for the determination of bulk density of metal powders - Part 2: Scott volumetric method. Simultaneously meet the reference international standardsIS0 3923—2：1981{Determination of Loose Density of Metal Powder2Part: Scott Capacity Meter Method. The basic structure and parameter requirements provided in the document meet the standard requirements for all indicators.

It can also be used for powder bulk density measurement with similar testing requirements, such as powder and particle testing for pharmaceuticals, refractory materials, etc; Consistent with international and domestic standards, this instrument is suitable for use with apertures that cannot flow freely5.0Standard funnel method and powder testing using vibrating funnel to easily change powder characteristics

take a sample:

3.1 When determining the bulk density of each powder, at least a small amount should be taken100cm3Divide the volume sample into three parts.

3.2 Usually, powders are measured according to their receiving state, and in some cases, powders should be dried. But if the powder is prone to oxidation, it should be dried under vacuum or inert atmosphere protection. If the powder contains volatile substances, drying is not allowed

FT-101Performance indicators of Skott volumetric density tester:

Upper funnel component: Material:304stainless steel; Upper end diameter Φ112mmLower end diameter Φ30mmTotal length:30+850mmScreen mesh:1.18mmStainless steel mesh or10Molybdenum mesh sieve

Fabric box: square, with four built-in pieces1Millimeter thick stainless steel baffle.

Square funnel:60A square cone with a lower diameter of12.5mm×12.5mm.

Cylindrical cup: Material:304stainless steel; The volume is25±0.05 ml.

Size:100 mm×160 mm×358 mm.

Calculation of experimental results:

The ratio of the mass to volume of metal powder is the bulk density, and the calculation formula is as follows:

In the formula: ρasPowder bulk density measured by the Scott volumetric method,g/cm3,

m: Quality of metal powder,g；

VThe volume of loose powder,cm3.

Take the arithmetic mean of three measurement results and report the final result0.01g/cm3When the difference between three measurement results exceeds the average value1%At the same time, its value and small value should also be reported along with the results.
