The spiral conveyor is a special type of vibratory conveyor that transports the product vertically. The product moves up the spiral as the conveyor vibrates.

The spiral conveyor combines the advantages of gentle product handling and vertical transport with vibration technology for bulk products suitable for feeding or in combination with thermal treatment. Transport is done via the micro-throw motion known in the vibrating technology. The operating parameters like vibrating stroke, frequency and angle of attack (throw-angle) will be selected individually to the application. The JOEST spiral conveyor for thermal treatment is suitable for

operation with different types of heat exchange media and temperatures. Special design for convective heat exchange is available too. Optionally, aspiration or overflowing of the transport surface is possible depending to the application. Static or co-vibrating housing is disposable. The design of the flights developed by JOEST enables an efficient heat exchange.

A high level of mechanical stability is achieved by welded lateral curb execution. Additionally the typical reduction of material thickness in the bending radius of press formed flights is not applicable. Two unbalance motors with adjustable angle of attack on the drive saddle, displaceable vibrating stroke and operation with frequency converter provides an efficient operation.

The Helical Casting Cooler is a specially designed spiral conveyor that uses vibration feeder technology to simultaneously cool and vertically convey materials. The conveyor belt has a slight incline and moves product up a spiral tower.

Helical casting coolers combine the advantages of gentle, vertical movement of materials using vibration feeder technology on a spiral conveyor while applying thermal treatment, and they can be driven by a variety of cooling agents. Product is moved using the micro throwing movement, a well-known technique in vibration feeding technology that can be individually set up for each application and machine type through the adjustment of swing, frequency and articulation (throw angle). Helical casting coolers are available for contact, convective and combined heat transfer methods.

With contact heat transfer – without direct contact between the cooling agent and the product – the double-bed design leads to uniform heat transfer over the entire width of the tower.  The design of the cooling plate, with welded platform panels, produces high levels of mechanical stability. This eliminates the normal reduction in sheet thickness in the bending radius required by otherwise standard pressure on the spiral tower. Cooling water supply from the cooling water distributor is also adjusted to suit the application when delivered.

For convective heat transfer, the cooling agent – with direct contact between the cooling medium and the product – is introduced directly to the product and either flows over or through the product.

The drive bracket has two variable unbalance vibrators in the pivot angles. This, combined with adjustable swing and adjustable operation with a frequency converter allows for optimal machine operation. Helical coolers can be delivered in a variety of materials including normal or stainless steels, or a combination thereof. Depending on the application, the helical cooler can be equipped with a static or oscillating enclosure as an option.
