Scope Specifies the requirements for screw conveyors of trough type for industrial use in sizes 100 mm to 1 250 mm nominal screw diameter. 2. Dimensions. 2.1 Nominal Size, D The nominal size, that is, the diameter of helical screw in millimetres shall be selected from the follow~ing :
Sep 27, 2021 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 in order to attain the required capacity.

Screw conveyors are used in many different fields for feeding, handling and dosing of bulk solids. Tubular type screw conveyors are available from 114mm to 323 mm diameter. Hardox, stainless steel or anti-corrosion coated flights are available for different industries in accordance with special applications and requests. · Nominal
The flexible screw conveyor carries the material to an elevated point at the required flow rate. The batching functionality of the LIW Helix allows for the measurement and automation of a dosed amount of material while conveying simultaneously. The LIW Helix is available from 3 to 8 inches (7.6 cm to 20.32 cm) nominal case diameter
Shaftless screw conveyors are most efficient at lower speeds and the acceptable speed range is typically between 20 and 40-rpm. If the calculated speed of the conveyor is outside the recommended speed range, change the trough loading or conveyor diameter
