Introduction: In the use of various types of powder industry, due to the particle shape, fineness, particle size distribution and cohesion, will directly affect the quality of the product, JX-JL-A3-type powder characteristics tester, with reference to national standards, from 2 sets of unique A stacked powder trays and B stacked powder trays, which are flexibly selected by the demand side. Both the A and B trays have liquidity, angle of rest (angle of repose) and bulk density. The test results are from Computer records to save, view, print easily. A stacked powder tray to maintain the principle of GB6521-86, by the traditional method of injection of powder, from a fixed height through the funnel, free fall on a standard eight-level metal plate to form a cone, cone cones Angle between the surface and the bottom is the angle of rest (angle of repose). B stacked powder disc using a new test method, the use of more convenient test results with high accuracy, that is, the middle of the funnel set a disc tray, when the powder flows out of the funnel, stacked into a stable cone, just cover the market Small cap, and then directly look at the scale on the lifting seat, read the accumulation of powder height. Need to know the loose density data, simply the instrument supporting 30ml standard sample powder tube, on the A plate or B plate, you can know the loose density data. Rest (angle of repose) test principle: Reference to international standards ISO902-1976, GB6521-86 principle. Under the condition of no vibration, the specimen freely falls on a horizontal metal plate with eight scales through a funnel to form a cone. The angle between the conical surface and the bottom surface of the cone is the rest angle angle). The angle of rest is generally calculated from the average diameter and height of the resulting conical specimens. Operation method The volume of the powder heap is controlled within a certain range of feed until the powder stops flowing out, stacked into a stable cone, the material on the hopper 8 radius input data into the computer, calculated by the software stack average radius and Material heap height, draw the rest of the powder. Results can be saved or printed directly. Liquidity test principle: Reference to international standards ISO4490-1978, the national GB1482-84 principle. For the determination of powder flow. Operation method: Block the outlet of the funnel at the bottom, weigh the sample 50g and pour it into the funnel. When the funnel hole is opened, start counting. Once the powder in the funnel has finished flowing, stop timing and record all the time , Whichever is the arithmetic mean, to obtain powder fluidity. Loose density test principle: Reference to international standards ISO903-1976, GB6522-86 principle. The specimen free-falling from a fixed height without vibration, filling a fixed container of known volume, and calculating the bulk density from the mass and volume of the specimen.
