How to judge whether jigging machine has normal production?
How to judge Jig Is it in normal production? What is the basis for normal production of jigging machine? This paper focuses on the issues concerned 1、 Apparent phenomenon of jigging machine in normal production
(1) the washing water pulsation of each section of the jig is uniform and stable, and the water surface on the air valve side and the operation side rises and falls synchronously. This shows that the pressure changes in each air chamber are harmonious and the jigging process is normal.
(2) when the water thickness of the inner surface of the jig is less than 50 mm, the thinner one presents fish scale wave (caused by surface particles), and the water velocity on both sides is the same or the difference is not obvious. This shows that the amount of top water and flushing water is appropriate and the distribution is uniform.
(3) the bed thickness has no big fluctuation in a short time. 2、 Tactile detection of jig in normal production
The jigger driver shall use tactile means such as probe rod to inspect the bed state and take it as the basis for adjustment
(1) each jigging cycle must be completed practically, that is, the bed should be dense before the next jigging cycle starts, otherwise the ideal separation result will not be achieved.
(2) the vibration of the upper and lower layers is not separated, and the gap between the upper and lower layers is particularly unfavorable to the fine particle separation.
(3) tight loose bed rhythm.
(4) there is enough sipping force when the water flow drops. Only when the sipping force is enough, can the driver adjust it according to his / her discretion. 3、 Scientific basis for normal production of jig
Although observation and detection can judge the sorting process, it is only a rough feeling, not a fine data. Therefore, it is necessary to use the results of rapid floating and sinking of coal samples or rapid test results to guide production.
