FOREWORD This publication, CEMA Standard No. 300 “Screw Conveyor Dimensional Standards”, provides recommended dimensional standards for major screw conveyor components. All Dimesions and Tolerances are based on Carbon Steel Fabricaton. These recommended standards are issued in conjunction with CEMA Standard No. 350 “Screw Conveyors”. “Screw Conveyors” is a comprehensive manual of engineering and application practice for screw conveyors. Both publications are intended to be American National Standards.

SAFETY NOTICE The Conveyor Equipment Manufacturers Association has developed Industry Standard Safety Labels for use on the conveying equipment of its member companies. The purpose of the labels is to identify common and uncommon hazards, conditions, and unsafe practices which can injure, or cause the death of, the unwary or inattentive person who is working at or around conveying equipment. The labels are available for sale to member companies and non-member companies. A full description of the labels, their purpose, and guidelines on where to place the labels on typical equipment, has been published in CEMA’s Safety Label Brochure, Brochure No. 201. The Brochure is available for purchase by members and non-members of the Association. Safety Labels and Safety Label Placement Guidelines, originally published in the Brochure, are also available free on the CEMA Web Site at http://cemanet.org/safety/index.html. A Safety CD, entitled CEMA A/V Number 6 "SCREW CONVEYOR, DRAG CONVEYOR, AND BUCKET ELEVATOR SAFETY CD". , has also been developed by the CEMA Screw Conveyor Section. It describes key safety practices people should adhere to when working with and around these different conveyors. It is available for purchase from CEMA. Additionally a free handout WARNING AND SAFETY REMINDERS FOR SCREW, DRAG, AND BUCKET ELEVATOR CONVEYORS is available for free download from the CEMA Web Site’s Safety Page PLEASE NOTE: Should any of the safety labels supplied by the equipment manufacturer become unreadable for any reason, the equipment USER is then responsible for replacement and location of these safety labels. Replacement labels can be obtained by contacting your equipment supplier or CEMA.
