Application：

Column & connection plate production line

Function: Used for producing column & connection plate of bolted silo.

Profile: Column & connection plate production line is composed of nine parts: feeding machine, leveling and inclined pinch face, forming unit, punching, cutting, automatic palletizing, electric controlling system and hydraulic system. The production line can serve the automatic production of all the columns & connection plates, the max forming thickness of plate can achieve to 10mm/16mm, which can meet the needs of constructing ten thousand ton silo. The service this production line can improve the production efficiency and the product quality of column.

Production capacity: Can produce column 800pieces/day (8 hours);
