Full title and description

ISO 1050:1975 — Continuous mechanical handling equipment for loose bulk materials — Screw conveyors. Short description: recommended (principal) values for the main dimensions of screw-conveyor elements. This item is commonly distributed as a short PDF (official ISO/electronic edition) and is available for purchase from ISO and many national standards bodies; English and French are the ISO reference languages. A Russian-language rendering or national adoption may exist through a member body or commercial translator, but ISO's catalogue lists English and French as the primary languages for this publication.

Abstract

This International Standard lays down the recommended values of the main (principal) dimensions of the elements that make up screw conveyors used for continuous mechanical handling of loose bulk materials. It provides standardized dimensional recommendations to promote interchangeability, compatibility and basic design consistency for screw, shaft, flights, trough/casing and related parts.

General information

• Status: Published — International Standard (confirmed).
• Publication date: 1 October 1975 (Edition 1, 1975); last confirmation of this version: 5 May 2025.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 53.040.10 — Conveyors; continuous mechanical handling equipment.
• Edition / version: Edition 1 (1975).
• Number of pages: 2 (short technical standard / PDF extract length).

Scope

The standard applies to screw conveyors used for continuous mechanical handling of loose bulk materials and sets out recommended (principal) dimensional values for the conveyor elements (screw/flight diameter and pitch, shaft sizes, trough/casing dimensions, end fittings, etc.). It is intended to guide designers, manufacturers and users toward common nominal sizes and basic compatibility; it does not replace project-specific engineering for capacity, strength, wear, or safety details.

Key topics and requirements

• Principal dimensional recommendations for screw conveyor elements (flight diameter, shaft diameter, pitch, trough geometry).
• Standardized nominal sizes to improve interchangeability of components and simplify design choices.
• Definitions of the main conveyor elements and the dimensional relationships between them.
• Guidance limited to geometry and nominal dimensions — does not cover detailed strength design, materials selection or safety guarding (those are addressed in other documents).

Typical use and users

Engineers and designers of bulk-material handling equipment, conveyor manufacturers, equipment specifiers and procurement teams, plant maintenance staff, and standards/quality departments use this standard when selecting or specifying screw-conveyor components. It is also used by national standards organizations when adopting ISO recommendations as national or identical standards and by educators as a reference for principal conveyor dimensions.

Related standards

Related documents commonly used alongside ISO 1050:1975 include safety and application reports and national/adopted versions such as ISO/TR 9172 (safety guidance for screw conveyors), national identical adoptions (for example SS‑ISO 1050 in Sweden), regional adoptions (e.g., GSO ISO 1050), and industry practice documents (ANSI/CEMA screw-conveyor guidance). Many countries also publish national versions or translations that incorporate or reference ISO 1050:1975.

FAQ

Q: What is this standard?

A: ISO 1050:1975 is an International Standard that gives recommended (principal) dimensional values for components of screw conveyors used to handle loose bulk materials continuously.

Q: What does it cover?

A: It covers the principal dimensions and nominal sizes of screw-conveyor elements (flight and screw geometry, shaft and trough dimensions, etc.). It does not provide design strength calculations, material specifications or detailed safety requirements.

Q: Who typically uses it?

A: Conveyor designers and manufacturers, plant engineers and procurement/specification teams, national standards bodies and technical libraries. It is used where standardized nominal dimensions simplify manufacturing and interchangeability.

Q: Is it current or superseded?

A: The 1975 edition (Edition 1) remains the published ISO document for ISO 1050. The ISO catalogue shows this version as published in October 1975 and confirmed as the current version (confirmed in 2025). Users should check with ISO or their national standards body for the latest confirmation status or any more recent replacements or national adoptions.

Q: Is it part of a series?

A: ISO 1050:1975 sits within the portfolio of standards maintained by ISO/TC 101 (continuous mechanical handling equipment). It is related to other conveyor and handling standards and technical reports (for example safety reports for screw conveyors and various national/adopted versions), but it is a standalone document addressing principal dimensions.

Q: What are the key keywords?

A: Screw conveyor, principal dimensions, bulk-material handling, conveyor components, ISO 1050, шнековый конвейер, размеры.
