The round belt turning machine is a turning device for green billets during conveying. It is an auxiliary equipment designed for the layout of the entire ceramic production line where the glazing line cannot be in a straight line. The turning arc, the number of mushroom wheels and the size of the round belt are determined by the size of the product. The best adjustment effect is achieved with dual motors and dual frequency conversion. The electronic control is segmented by the PLC program to interlock the upper and lower processes.
