the usual method of angle of repose is to fix the cone method (also called residual conic method).Fixed cone method : inject powder to the center of disc with limited diameter, until the hypotenuse powder accumulation of material automatically flow along the edge of disk, stop injection, measure angle of repose.
test time and angel of powder and particle pass through the funnel , preaccumulate before testing, so as to determine the sample weight, the known mass powder flowed from the funnel and form the accumulation of Angle, and the time it takes to outflow;You can obtain the angle of repose and the flow rate data.
With the Angle of repose evaluation flow properties of powders, can only say the stand or fall of liquidity, or used to compare the same powder liquidity difference caused by moisture and particle size, etc.
參照GB11986-89《表面活性劑 粉體和顆粒休止角的測定》
It was designed and manufacured According to GB11986-89 "determination of surfactant powder and particle angle of repose "
ISO4324-1977要求;粉體和顆粒休止角的測定,
ISO4324-1977 requirement; The determination of the Angle of repose t for powder and particle
參照USP(美國藥典)、BP (英國藥典)和EP(歐洲藥典):DIN ISO 4324 - December 1983
It also Applies to USP (the United States pharmacopoeia), BP (British pharmacopoeia) and EP (European pharmacopoeia) specification requirements of the reference standard: DIN, ISO 4324 - December 1983.
They are widely used in pharmaceutical, chemical industry, washing, scientific research institutions, quality inspection institutions, and so on related detection of powder and granular materials;Changes in the properties of the powders can be provided, especially in the silo Storage conditions etc.
