  First, start and stop conveyor should normally start in the no-load conveyor beltditions。 Sequential installation of several units in the belt should be used to lock the starter to set the control room by a certain sequence of start and stop。
   Chuci in addition, to conveyor beltvent incidents, each conveyor should also set the place to start or stop buttons can be individually stopped Renyiyitai。
   In order to conveyor beltvent the belt for some reason were longitudinal tear, when the conveyor is longer than 30m, the length along the conveyor should be a certain conveyor belttance away (such as 25m30m) install a stop button。
   2, conveyor belt maintenance to ensure reliable operation, the most important is to conveyor beltcover and rule out the possible failure。
   To do this the operator must always observe the work of transport, such as abnormal should be a timely manner。
   mechanics should be regular inspections and check for any situations requiring attention or components,conveyor belt such as 25m30m, it is very important。
   such as a roller does not seem important, but the high-speed conveyor belt material transport and wear it in the shell may soon worn out,conveyor belt must meet the following requirement, the emergence of a blade, the blade could seriously damage an expensive belt。

  1mm。 but in full on the rack conveyor center of the error shall not exceed 35mm。 When all the single install and to identify the following may be the single link。
