Vertical screw conveyors are used to vertically lift all kinds of bulk materials. They have a small footprint and are suitable for almost any factory layout. So how to choose a suitable vertical screw conveyor? Here are 8 tips to get you started.
Judging whether a vertical screw conveyor is suitable for conveying the properties of the product, is your product: free-flowing, such as liquid or powder? Or is it immobile, like heavy rubble? Failure to select the correct material to be conveyed may result in damage to parts or may clog the site. Material that is too wet or too viscous will prevent the spiral from rotating upwards.
Knowing your product makes it easier to determine how the screw shafts in your conveyor should be designed.
Free-flowing materials require larger diameter screws with shorter pitches.
Sticky or sticky products benefit from a shaftless screw that allows the product to flow freely.
Some products have special material requirements. This will affect the coating of the screw, casing and other components of the screw conveyor. For example, food powder needs to be strictly sealed during screening and to ensure that the material is not contaminated, so it needs to use SUS304 or 316L stainless steel material, if no corrosion resistance or For cleanliness, Q235 carbon steel is used, and the cost will be lower.
The height of the vertical screw conveyor refers to the distance from the inlet to the outlet. For transporting products in high places or in small silos (8m height difference), when the lifting height needs to be increased, an intermediate hanger or stabilizer is usually required. actuator bearings to eliminate excessive helical deflection.
The above is an introduction to the selection of vertical screw conveyors. To choose a suitable vertical screw conveyor, factors such as conveying products, space, conveying volume, conveying height, etc. should be fully considered.
