Live Bottom Bins, Vibratory feeder

Bin activator is made by vibrating feeder hopper, fixed bucket, damping device etc. It is a new type feeding equipment installed below various feed bin. It makes the material loose with the vibration of the motor, so that it can eliminate the material arching camber,blocking,attaching problems. With the Motor power on, it will form an inertial exciting force, so that the spherical activates to produce a strong horizontal vibration in the vibrating hopper. Horizontal vibration is decomposed into component force from two directions: one is along the spherical normal and another is along the tangential direction .The exciting force makes the materials active to eliminate all the storage of arch camber, jam and stick on the warehouse, so that the materials can continuously and evenly outflow the warehouse.

Bin activator is a new equipment has broken arch, closed three functions of feeding

Bin activator 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.


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, No Screw conveyors attached.


Bulk material silo GZD series of inertial Bin activator is widely used in coal, electric power, machinery, chemical industry, building materials, metallurgy, mining, light industry, food, food, medical, transportation and other departments of the arch breaking, feeding, shut down operations.

Bin activator has been successfully tried on all difficult to handle material like surphur and its compounds, fine macro powder and other inerals, ore titanium dioxide, wood chips, salt, sugar and other fine, flake, fibrous and sticky materials.

Silo Discharge Aid for Calcium Carbonate, Lime, Limestone-Crushed, Flour, Sugar, Starch, Activated Carbon, Aluminia, Carbon Black, Clay, Diatomaceous Earth, Magnesium Oxide, Salt,Soda Ash, Titanium DiOxide, Zinc Oxide, Vibra.

Integrated baffle support

Hanger arms allowing horizontal vibration

Maintenance-free unbalance motor

Bin activator diameters from 600 to 2200 mm

Mild or stainless steel bin activators available

Both broken arch, feeding, shut down. Broken arch help flow ability; The feeding loose, continuous, uniform and accurate; Vibration stops, the material that is to stop discharge, don't need to install the gate of silo.

Quantificationally adjustable, easy to realize single machine or group of machines, automatic control, no material particle size segregation in the process of discharge, and there was a mixed effect.

Simple structure, installation is simple; Reliable operation, easy maintenance.

Light weight, less consumption and operating cost, low operating cost, good vibration isolation, less abrasion, low noise.

Low installation height, can replace the silo cone or part of the cone, don't need basis and additional devices.

Good sealing, implement fully enclosed, without local dust or gas.

Bin activator controlled by the reverse connect brake electric control box. The control box can use vibration to the bin activator quickly stop in a short period of time,the bin activator fast through the resonance region, to the easy worn parts and the sealing ring in order to protect. As in the feeding process to continuously adjust the feeding quantity, can be equipped with inertial motor VVVF, adjusting the inertia of the motorspeed, so as to adjust the vibration force, to achieve the purpose of adjusting thefeeding quantity.
