For Style CC-HD Agricultural Duty Buckets Available in Four Standard Patterns

A vented bucket can improve the efficiency of some bucket elevators when handling certain products. On dense materials such as flour, meals and mash feeds, the vents allow air to escape through the cup as it fills, which permits the cup to fill more completely. During discharge air can return through the cups as it empties, thus preventing a vacuum that could hold some of the product in the cup and cause back legging. On extremely light materials such as alfalfa meal, screenings and bran, a vented bucket not only minimizes blowing of the product during loading and discharge, but also reduces air turbulence in the leg as the bucket travels empty down the return side of the elevator. A reduction in air currents minimizes the vacuum which can draw a light product through the down leg and back to he boot.

Tapco has four standard patterns available which offer varying amounts of air release for the handling of most products. Special patterns and hole diameters will be quoted upon request.

NOTE: Most steel bucket manufacturers use vent hole with 1/8" to 5/32" diameters. These small holes, if used in the Tapco nonmetallic bucket would soon become clogged with product due to our thick wall sections. For this reason our standard vent diameters are 9/32"  and 11/32".
