Used in 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 metalfab bin activator, carmen, vibra motion with no screw conveyors required.

Application 1: Bin Activator Mounted On Silo Discharge Cone Hopper
Very few silo projects are successful without the use of a live bottom bin activator. We engineer the proper size bin activator to: • match the bulk solid being stored in the silo • the diameter of the silo • the height of the silo • recommend the slope of the silo hopper angle • design the correct discharge opening to obtain the product flow • capacity for your operation
Application 2: Silo Hopper Bin Activator With Dual Volumetric Screw Feeder Continuous Discharge
This is a typical industrial bulk solids application to provide continuous metered flow of sluggish, non-free flowing powders. The live bottom bin provides first in first out flow pattern into the volumetric crew feeder. The screw feeder will only provide +/- 1% to 2% continuous output if the volumetric screw flighting is 100% filled. These (2) pieces of equipment working in tandem will allow you to feed your process in an uninterrupted fashion.
Application 3: Silo Hopper Bin Activator With Rotary Valve Feeder Continuous Discharge
Silo discharge to pressure or vacuum pneumatic conveying line applications for non-free flowing powders require rotary valve feeders to meter bulk solids into the conveying line. . The live bottom bin provides first in first out flow pattern into the rotary vane feeder. The bin activator will fill the vanes of the rotary valve to provide continuous output. These (2) pieces of equipment working in tandem will allow you to feed your process in an uninterrupted fashion.
