portable concrete batching plant using contrast

We recently went to study abroad look on portable concrete batching plant applications in foreign countries , when we arrived , we saw their operating very surprised.
concrete batching plant in donesia, their application is not pay attention , looking at concrete mixing plant body has a lot of junk , like , not turn , the body can not withstand the feeling that we asked them some questions about the operation , basically, they did not follow the instructions given to operate on .
In Germany , concrete batching plant germany, they only do very seriously , cement weighing hopper upper material inlet and outlet connections screw machine , not too tight , nor too loose , too tight will affect the accuracy of the scale , over pine affected the smooth feed ; cement weighing hopper feeding port and the host connection process is bad, because the accumulation of material and the formation of lumps on solidification hopper cause supporting role, scales of measurement may not be accurate. These critical operations they are very clear , and we feel very admirable .
