Vertical Conical Blenders are very sturdy and robust. They consists of a conical vessel with dished /flat head. The central agitator shaft is driven from top end with gear reducer. A double helical ribbon agitator in the vessel moves the product upward. When the screw is in spiral rotation. The powder which do not touch the screw are moved downward by the weight themselves that the powder may move repeatedly by various forms. Mixing time is depending on the agitator speed. In general mixing time is three to four times shorter than the mixers working with a rotating screws.
The drive and bearings are kept outside of the vessel, no gears or seals in the product compartment. The rotating central agitator shaft does not have bottom bearing support there by eliminating any dead spots or difficult areas to clean and there is no danger of product contamination.
