JL-A3 Powder property tester angle of repose Powder liquidity analyzer

Brief introduction

The shape, size, size distribution and cohesiveness of the powder will directly affect the quality of the product. Therefore, in a variety of powder processing, the use of the industry, the use of good control of product quality analysis equipment is particularly important. JL-A3 type powder properties tester can test the powder flow, repose angle (angle of repose), bulk density, it is an ideal instrument for powder industry to test the properties of powder.

Features

1 type JL-A3 powder characteristics test instrument, equipped with 2 sets of A, B accumulation of powder, with a unique flexible conversion device, respectively, to obtain the rest angle, powder flow, bulk density of 3 kinds of data. The test results are recorded by the computer analysis, save the view, easy to print.

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.

4 powder flow test method: block the bottom outlet of the funnel, the powder sample weighing down 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 on the disk in drive a or B 3, funnel and a standard measuring cylinder center superposition, samples 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.

Technical parameter

Powder repose angle (angle of repose) with reference to the international standard GB6521-86, national standard ISO902-1976.

Reference to the international standard ISO4490-1978 powder liquidity, the national standard GB1482-84.

Bulk density of the powder is in accordance with international standards ISO903-1976, national standard GB6522-86.
