Venting an elevator bucket aids in bucket fill and discharge with light, fluffy materials.

Lightweight, fluffy materials, those that are extremely dense or flow poorly can be difficult to handle in bucket elevators at high speeds. Because these materials tend to trap air when being handled by an elevator bucket, it is necessary to provide air relief to assist in their filling and discharge. Materials in this category might be various flours, meals, feed mash or screenings. As these materials enter the bucket, air is released through a series of vent holes in the bottom of the bucket allowing for a more complete fill. These vent holes also allow air to re-enter the bucket, which facilitates full release of product into the discharge.

Standard hole diameter is equal to the size of the bolt mounting holes in vent pattern #1, all other vent patterns will have 11/32” diameter holes unless otherwise requested by customer.

When elevating powdery materials such as cement in the Tiger-Tuff, a minimum of two rows of 3/8″ diameter vent holes are recommended to help insure that the material will discharge cleanly.
