Definition of natural bulk density meter:
The angle of repose refers to the angle formed by the free inclination of the powder accumulation layer and the horizontal plane in a static equilibrium state; /p
How it works:
The most commonly used approach angle method is the fixed cone method (also known as the residual cone method). In the fixed cone method, the powder is injected into the center of a disk of limited diameter until the material on the hypotenuse of the powder accumulation layer automatically flows out along the edge of the disk. The injection is then stopped and the angle of repose measured.
Features of Natural Bulk Density Meter:
The test powder and particles flow into the test hopper after passing through the hopper, and then flow automatically out and accumulate, solving the problem of powder gelbecomes east. Due to the influence of gravity and the internal friction of the product itself on the natural flow of powder and particles during feeding, the data obtained can better reflect the properties of the product itself;
If the fluidity of the powder is bad. If it cannot flow out, add 100 μm glass beads to aid flow. The choice of flow aid should be chosen according to the actual properties of the product. Determine the minimum amount of glass beads required for free flow. The
Powder and Particle Shaking Angle Tester conforms to GB11986-89 “Determination of Surfactant Powder and Particle Shaking Angle”. Determination specifies that design and production conform to the requirements of ISO4324-1977;
Determination of the angle of repose of powder and particles; also applies to USP (United States Pharmacopoeia), BP (British Pharmacopoeia) and EP (European Pharmacopoeia) standard requirements Reference standard: DINISO4324-December 1983;
Can also be used for similar test requirements to determine the Measure product flowability and meet international common test method requirements.
The powder and particle bed angle measuring device can not only measure directly, but also the height of the powder layer and the radius of the diskcalculate e. That is, tanθ=height/radius.
The angle of repose is a convenient way to test the flowability of powder.
Scope of application:
The device for measuring the angle of repose of powders and particles is widely used in the fields of pharmacy, chemical engineering, washing, scientific research institutions and quality inspection institutions, etc. Detection of related powder and granular materials; can lead to changes in powder storage properties, especially storage conditions in silos.
