The STOCK REDLER Circular Bin Discharger (CBD) is a well proven and established positive discharge aid for hoppers and silos where the material to be handled has characteristics which make it difficult to discharge or control. A rotating arch breaker arm travels around the hopper bottom section of the silo breaking any bridge of material which may have formed. This ensures a flow of material to the discharger which can be supplied as a single, two or three stage unit to suit the characteristics of the material to be handled and the through puts required. The standard range comprises two sizes: 800mm and 1000mm diameter.
Besides functioning as a bin discharger, the STOCK REDLER CBD can be used to maintain a head of normalised material in the outlet chute, thus assisting the accuracy of subsequent metering or weighing equipment. Material in excess of the take away rate is re-cycled.
The STOCK REDLER CBD is driven by a single drive controlling the rotation of both the discharger and arch breaker arm. Actual drive arrangements vary according to the application or customer requirements.

The STOCK REDLER CBD has solved discharge problems in a variety of industries including: Food, chemical, process, coal, brewing, cement and particle board. The CBD size and type selection is dependent upon the features of the material to be handled and the storage capacity of the bin. Generally, the storage bin should be of circular construction and have an Aspect Ratio of between 2 and 3, where:

The external angle of the hopper bottom should be 50 degrees to suit standard CBD's. Please refer to STOCK REDLER for specific recommendations to suit your particular discharge problem. We can also advise and supply details regarding bin design and submit proposals for the supply of the silo if necessary. In its standard form, the CBD is fabricated generally from mild steel. For corrosive or special applications, contact parts can be supplied in stainless steel or material to suit of a grade to suit customer requirements. Access and inspection doors are incorporated in each stage as standard. Outlet position can be specified in one of three positions and special 'blister' or larger outlets can be incorporated for light bulky materials.
SINGLE STAGE CIRCULAR BIN DISCHARGERThe simplest form of CBD, for the free discharge of materials which have a tendency to arch or bridge. The output is dependent upon the flow or break away rate of material due to the action of the arch breaker and the speed of the CBD. Capacities up to 200TPH have been achieved with certain materials. |

TWO STAGE CIRCULAR BIN DISCHARGERA second stage can be added to bring the material flow rate under control. Material leaves the first stage to be contained by flights in the second stage prior to discharge through a single outlet port. Volumetric discharge within reasonable degree of accuracy is possible with many materials. |
|
THREE STAGE CIRCULAR BIN DISCHARGERMaterials which are prone to fluidise and flow uncontrollably can be brought under control and discharged consistently through a three stage unit. The addition of a third stage creates a form of labyrinth to contain and control the flow prior to discharge. Typical applications would include cement, fly ash and plaster. |
