Feeder machine offers two alternatives
Feeding system that overcomes product bridging and poor discharge problems in storage vessels has recently provided additional benefit for two users.
The Circle Feeder, from the Yoshikawa Corporation of Japan, already well known as the ideal device for overcoming product bridging and poor discharge problems in storage vessels, has recently provided additional benefit for two customers who have installed them One of these, a manufacturer of sodium sulphate, stores his finished product in two 100M3 capacity silos

Agitating sluggish products improves discharge
Instead of using vibration or fluidisation methods to assist sluggish product discharge, a silo/hopper discharge aid encourages mass flow material discharge through mechanical agitation.
Vibratory pellet screen removes unwanted product
Vibratory pellet screen, a novel machine intended for installation in the extrusion line, after the granulator, screens out all out-of-specification products from quality pellet.
The product has a tendency to harden into lumps in the silos and discharge, which had to be made either into bulk tankers or into big bags, became increasingly difficult - until the client fitted each silo with a specially designed 2400mm dia.
Circle Feeder.
Not only did these units eliminate the problems with product discharge, it proved possible to use dedicated discharge ports either for tanker filling or for big bag filling by varying the discharge speeds of the rotating vanes of the Feeder.
Result- discharge problems eliminated, and controlled feed according to need.
A second client, who manufactures feed stock material for the pharmaceutical industry, also benefited from the Circle Feeder, when using it as a discharge aid to extract a wet cake product from storage.
This product, which has an average particle size of 65µ, is dried by centrifuge to a moisture content of approx 18%.
Because of operating procedures, it is not acceptable to pass this product directly into a drier for final moisture removal and, as a consequence, a buffer storage hopper is required.
Before the installation of a Circle Feeder the damp product tended to hang up in this hopper and discharge to the drier proved difficult and inconsistent.
After installing the 1000mm diameter Circle Feeder, which was fitted with two discharge ports, the client is now guaranteed controlled discharge of consistent volumes of products to his drier, and has the option to discharge reject product to big bags for reprocessing.
The Circle Feeder consists of a stationary base plate, an inner flow control ring with centrally located rotating vanes, and peripheral rotating vanes mounted on an outer ring.
The drive shaft, which carries the speed reduction geared motor, passes through the centre of the base plate and connects to the rotating vanes.
