At times flowability of certain powders is so poor that discharge from silos assisted by flow aids like aeration pads, pneumatic hammers, hammer blasts or even air cannons is impossible.
In such cases a Bin Activator is the ultimate flow aid and extracting device for such materials.

Vibra-Jet™
Bin Aerator
Model K Series 683
Restores material flowability at low cost
The Model K Vibra-Jet bin aerator, when installed on any storage silo, bin or hopper, can be extremely versatile and effective in getting dry bulk materials, like fine cement, to gravity feed more reliably at a very low cost. Materials which tend to pack, bridge or hang up can be made to flow freely and instantly upon demand.
Balances the natural negative pressures during discharge
Model K Vibra-Jet bin aerators installed at strategic locations on a discharge cone of a storage silo, bin or hopper direct high or low pressure compressed air along the bin wall to reduce the coefficient of friction which exists between the bin wall and the stored material. The compressed air, which is injected in short high-pressure bursts, fully balances the natural negative pressures created during the normal discharge process. By controlling the compressed air pressure and volume, materials once thought to be difficult to handle now gravity feed easily, quickly and automatically.

This type equipments use to activate the regular flowing of poor-flow materials through away from outlet of the silos. Bin activators produce in several models (as OT-600, OT-1000, OT-1200, and OT-1500) depending on the different sized silos.

Used in the Bulk Solids Material Handling Systems, Bin Activators, also known as Live Bottom Bins, Shaker Bins, or Vibrating Silo Bottoms are used to create flow of dry bulk solids from vertical storage bins. The Live Bottom will overcome sporadic or irregular discharge problems created by arching, bridging, and rat-holing. The typical geometry on a standard 4:1 vertical round bin is a live bottom that is half the diameter of the silo.
How It Works:
Positive discharge or First In First Out (FIFO) Flow of the silo is accomplished by the internal cone-shaped baffle which is rigidly attached to the body of the bin activator. This vibrated cone, replaces a major portion of the standard fixed cone. The entire bin activator unit moves horizontally by the unbalanced weights of an attached vibrator. The cone baffle relieves the weight of the material from the lower section of the bin activator, and acts like a wedge as it moves beneath the material and pushes it in all areas adjacent to the cone's surfaces. This powerful force is also transmitted to the material in the upper portion of the bin as the motion is carried from particle to particle. Product discharges around the periphery of the baffle toward the outlet of the bin activator.
