Brief introduction The powder particle shape, fineness, particle size distribution and cohesiveness, will directly affect the quality of the product. Therefore, in a variety of powder processing, the use of industry, analysis of the selection of instruments to control the quality of products is particularly important. JL-A3 type powder properties tester can test the fluidity of the powder, the rest angle (angle of repose), bulk density, is an ideal instrument for physical characteristics of powder industry test powder. Features 1 JL-A3 type powder characteristic tester, equipped with 2 sets of A, the accumulation of B powder in a flexible disc, unique conversion device, respectively, the angle of repose powder fluidity, bulk density of 3 kinds of data. The test results by computer analysis record, save the view, easy printing. 2. The angle of repose testing method 1: maintaining the traditional injection powder old method, the powder from the fixed constant altitude through the funnel, the free fall in eight scale level on the metal plate, forming a cone, the cone of the conical surface and the bottom surface of the angle between the repose angle (angle of repose). 3. Rest angle test method is a new method to measure, namely funnel center position set a plate plate, when the powder through the funnel flow to the fixed plate plate, powder piled into stable cone, just cover the small cap Market. By reading scale out powder stacking height can be calculated powder repose angle. Fluidity test method 4 powder: blocked funnel bottom outlet, the powder sample weighing after poured into the funnel. Open funnel hole at the beginning of time, funnel powder by flow after, immediately stop the clock, record funnel all sample flow after the time obtained powder flowability. . loose density test method: instrument with standard powder tube, put in a or B disc funnel with standard cylinder center coincide, the sample into the funnel into the standard cylinder, when the specimen is on top of standard cylinder into a cone, began to overflow when to stop sampling, and then with a straight ruler along the standard cylinder edge gently scraping to excess sample and normal parallel test 2 times, take the arithmetic mean value for the final result, obtained apparent density data.
