Vibrating Bin Activators
Vibrating Bin Activators are designed for use of an internal cone-shaped baffle which is rigidly attached to the body of the bin activator by means of rugged structural tubular members. The entire bin activator unit moves horizontally in response to centrifugal forces generated by the unbalanced weights of an attached vibrator.
Constructions
The vibrating bin activator is made of a stamped bottom with a discharge cone. A nose cone is supported inside the stamped bottom by cross-profiles welded on edge to avoid the retention of product.
A vibrating motor – two in some cases – is set outside the stamped bottom. The vibration amplitude is adjustable by positioning weights to each end of the shaft.
This device is suspended at the base of the silo by the mean of suspension rods fitted with elastic joint at each end to prevent the transmission of vibrations to the sides of the silo. The number of suspension rods depends on the type of each vibrating bottom. These suspension rods are connected to the silo by the mean of an angle bracket welded or bolted to it.
Common Features
The diameter of the internal anticharge cone is smaller than the opening of the silo. The resulting annulus is calculated to ensure the requested capacity.
The design of the vibrating bottom is determined by several parameters: size of the silo, the product's physical characteristics and the requested capacity.
It can vary between 1 / 3 the diameter of the silo to free-flowing and 1 / 1 for fibrous or flaky.
The output of the vibrating bottom is linked by a flexible connection to equipment located downstream in order to avoid transmission of vibrations.
