Elevators – also known as vertical conveyors – can be used to transport bulk goods up or down. Another option for vertical transport is screw conveyance. Besides taking up little space, these transport methods also require a lot less energy than, for example, a conveyor belt that is placed at an acute upward angle.
Process:
Conveying & HandlingWhereas conveyor belts are well suited for the horizontal transport of (bulk) goods, vertical transport can be realized most effectively with elevators or screw conveyors. Elevators are also known as vertical conveyors, because buckets (a kind of shovels) are transported up and down using a belt or chain conveyor to be emptied and/or filled at the right floor. In screw conveyance, the rotational motion of the screw causes the product to be conveyed up or down. Both systems are reliable, energy-efficient and relatively resistant to contamination. In addition, these forms of transport are maintenance-friendly and suitable for short distances.
Mechanical vertical transport can be used for both small and very large transport quantities. Depending on the product to be transported and the desired transport speed, different types of screws and different types of elevators can be chosen. In addition, not only the quantity of product per hour is variable, but also the type of product. Mechanical vertical transport can be used for bulk goods, but also fragile or explosive products. The system requires relatively little maintenance, but the moving parts must be properly shielded to prevent industrial accidents.
Mechanical vertical transport can be realized using elevators or a screw. Both systems can handle bulk materials as well as loose materials and both systems are available in different versions.
Elevators are highly suitable for vertical transport of large quantities of product. Elevators from Dinnissen take up minimal space and can be integrated into existing and new production lines. Depending on the product to be transported, we have various types of buckets. Elevators can bridge one floor and are also suitable for multi-level transport. Elevators are suitable for transporting ingredients that are sensitive to abrasions, such as sugar, compound feed, chemicals, chalk, sand and cement.
Depending on the specific situation, elevator conveying can be done vertically or in a Z- or U-shaped pattern. For granulates or very fragile products, shuttle cups can be used. Furthermore, it is possible to install a pre-dosing system. The containers are available in polished or unpolished stainless steel, plastic and wear-resistant steel.
A screw can be used for both horizontal and vertical transport and is mainly used for short distances. Screw transport is very suitable for products with a high viscosity. Sticky or clumping material, such as a paste, syrup, or slurry, is transported smoothly by the rotating movement of the screw. This transport system with a low loading factor is also very suitable for transporting fragile products.
A screw conveyor from Dinnissen is available with single screws, double screws, or concave screws (overlapping/converging screws). In addition, the angle of the screw can be adapted to existing installation(s). Dinnissen's screw transport consists of a cylindrical tube in which a spiral screw is mounted concentrically. You can also use a screw conveyor without a tube. This is called a screw auger. For environments with strict hygiene requirements, Dinnissen supplies special easy-to-clean systems, equipped with shaftless screws or screws that can be easily removed.
The way a vertical conveyor system works depends on the chosen form. Whereas with elevators, each time a ‘batch’ is transported by a bucket, screw conveyance involves a continuous flow of product, which is rotated further and further into the screw.
Mechanical vertical transport with elevators is a powered form of transport that carries (bulk) goods from top to bottom or from bottom to top. Elevators work with a powered conveyor belt or chain conveyor, to which buckets are attached that are filled and emptied.
Another form of mechanical vertical transport is screw transport. This solution is not only suitable for vertical transport but can also be installed horizontally or at an angle. Screw conveyance consists of a tube with a driven screw-shaped interior. Through its rotating movement, the product that is inside the tube gets transported.
