Spiral conveyors are used in processes that require the moving raw materials or finished products to remain on the belt for a long time to carry out the technological process, such as cooling, blast freezing, drying, etc.
A spiral conveyor is a structure consisting of vertical supports and supporting guides installed spirally around them. The supporting guides form the base on which the conveying element (metal mesh or modular belt) moves.
The conveying element can be driven by a central drum or a side drive.
A design with a central drive drum consists of the central drum itself, on which vertical plastic profiles and horizontal sliding profiles are mounted. The vertical profiles drive the conveying element by frictional force against the edges of the conveying element.
The design of the lateral drive is a vertical shaft connected to a gearmotor, on which drive sprockets are mounted, which are assigned to each corresponding turn of the conveyor. The sprockets engage with the conveying element, thereby driving it.
Types of spiral conveyors:
The spiral conveyor has a complex design and, when using a side-driven spiral conveyor, requires lubrication.
SPBelt specialists have improved the design of the spiral conveyor and developed their own unique solution that does not require the use of lubricants during its operation.
This is achieved through the use of stainless steel mesh, which has a unique patented design. The mesh runs on profiles made of ultra-high molecular weight polyethylene, which ensures a constant extremely low coefficient of friction between the mesh and the sliding profiles.
Benefits of the side drive spiral conveyor:
We go to the enterprise, select a solution taking into account the customer's tasks, the characteristics of the transported product and the technological process. We draw up a technical specification and prepare an estimate.
We are developing a technical solution, performing 3D modeling and engineering calculations. We are approving the project with the customer.
At the request of the client, we equip the conveyors with additional equipment and make adjustments. automated control of conveyor lines.
We carry out installation and commissioning, service, warranty and post-warranty service
We are training operators for subsequent pipeline maintenance
