The size of screw conveyor depends on two factors. 1. The capacity of the conveyor. 2. The lump size of the material to be conveyed (Maximum dimensions of the particle) For the transportation and dispensing of bulk materials, screw conveyors are one of the most often used machinery. The size of a screw conveyor must be calculated in numerous projects …
The capacity calculation for screw conveyors takes into account the outside diameter of the screw, the outside diameter of the center pipe, the pitch of the screw, and the trough loading. The calculation determines the capacity that will be conveyed with each revolution of screw rotation.

Vertical Screw Conveyor Design Calculation Pdf. This article proposed an efficient design method for the vertical screw conveyor based on TCP-SHV. This method increases the throughput of the vertical screw conveyor by 20 for the same screw radius, the same pitch, and the same particle. ...
Any screw conveyor located on an incline over 45-degrees is considered as a vertical screw conveyor. The compact design allows for the vertical screw conveyor to fit into almost any plant layout. With a minimum number of moving parts, the vertical screw conveyor is a cost-effective and dependable component of any bulk material handling process.
the conveyor . For screw conveyor design purposes, conveyed materials are classified in accordance with the code system in Table 1-1, and listed in Table 1-2 . Table 1-2 lists many materials that can be effectively conveyed by a screw conveyor . If a material is not listed in Table 1-2, it must be
The design procedure for vertical screw conveyors does not differ from that for horizontal and slightly inclined screw conveyors, but available screw conveyor configurations are limited. In ANSI, screw size, corresponding capacity and a range of rotational speed are provided in a table.

Vertical screw conveyors – smaller footprint, less wasted space. Vertical screw conveyors are useful for all industries that convey products through a normal screw conveyor but the additional advantage of this system is that the steeper angle allows products to be transported almost vertically via equipment that will take up much less overall floor space.
