The Circle Feeder - one machine, two
alternatives
The Circle Feeder, from Yoshikawa, is well known as the ideal device for overcoming product bridging and poor discharge problems in storage vessels: two recent examples are quoted
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

A new discharge aid for silos and storage hoppers
The Circle Feeder, a new silo/hopper discharge aid, is being offered in the UK by Robin Engineering Services in North Staffordshire, proved on glass cullet, mortar mixes and many other applications
Further success for the Circle Feeder
The Circle Feeder presents a unique opportunity to solve the discharge problems which can occur when dealing with low density and fibrous products, such as cellulose and film flakes, in silos
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 diameter 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 65u, 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 dia.
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.
