Asfalt mešalna naprava je ena glavnih opreme za proizvodnjo asfaltnega betona. V določenem deležu lahko meša asfalt, gramoz, cement in druge materiale, da pridobi izdelke, potrebne za gradnjo avtocest. In order to ensure its operating effect, the asphalt mixing plant also needs to be powered on for test run before it is officially put into work.

The first step of the test run is to operate a single motor and check the current, steering, insulation and mechanical transmission parts at the same time. Po potrditvi, da vsak del motorja in mehanskega prenosa deluje pravilno, se izvede povezan preskusni zagon. During the whole process, it is necessary to conduct a patrol inspection of its key parts, and find out the cause and eliminate the abnormal sound in time.
Ko je napajanje vklopljeno, vklopite zračni kompresor, da njegov zračni tlak doseže nazivno vrednost tlaka. Na tej povezavi je jasno razvidno, ali pušča regulacijski ventil, cevovod, jeklenka in druge komponente. Then connect the oil supply and oil return devices, oil supply and oil return pipelines, etc., to ensure that they are not leaking, and use anti-rust components or take anti-rust measures.
Ker je v napravi za mešanje asfalta veliko mehanskih delov, mora celoten niz preskusnih voženj upoštevati vse vidike, kot so hidravlični del, transportni mehanizem, sistem za odstranjevanje prahu itd., od katerih ne smemo izpustiti nobenega.
