AI Technical Summary
Existing fertilizer blending equipment uses a single mixing method, which cannot guarantee uniformity. When multiple fertilizers cannot be added at the same time, they are prone to separation and require long mixing time, which is a waste of time.
The mixing is achieved by rotating the mixing disc at the bottom of the mixing tank, combined with the circulating stirring method of the feed inlet and the screw conveyor. The fertilizer is centrifugally sent to the edge of the mixing tank through the distribution plate, and the screw conveyor is used to prevent stratification and improve uniformity.
It effectively prevents fertilizer stratification, improves mixing uniformity, shortens mixing time, and increases production efficiency.
