Screw Conveyors for Bulk Materials
ANSI/CEMA Standard No. 350-2021. Accepted engineering and application practice as compiled by engineers of leading screw conveyor manufacturing companies. Illustrated and contains many tabular data on conveyor selection/handling characteristics of materials ordinarily handled in screw conveyors. Attention is given to horizontal, inclined, vertical and a number of special types of screw conveyors both for straight handling and for processing.
Summary of Changes
In 2019, the Screw Conveyor Section reviewed and modified sub-standards: 300-001, Dimension B should
read “Nominal Thickness” after determining that everyone’s machine will vary in the thickness based on the
quality of the machine, 300-019 was separated into two sub-standards, 300-019A 2-Bolts Coupling Shafts and
300-019B 3-Bolts Coupling Shafts and dimensions for 3 15/16”, 4 7/16” and 4 15/16” were added; a balance of
dimension on the 300-013 and 300-014 were added and review of the “J and “K” dimension in 300-013. Some
sub-standards were reviewed to add the dimensions for 30” and 36” including the hangers. Additionally, all
graphics in the standard were updated cosmetically.
