The BWS is designed to build a dynamic knowledge base which will be a resource for the global in-motion weighing community. The aim is to establish best practice benchmarks for in-motion weighing, and to provide a venue for discussion of important issues.

Global trade is becoming an increasingly significant part of the economy of most countries, particularly those with significant mineral wealth, such as Australia. An understanding of this is reflected in the increasing requirement for Trade Certification of In-motion Weighers for legal trade by government bodies worldwide. The need for reliable, repeatable accuracy in weighing of bulk materials has always existed. The BWS is here to facilitate progress and dialogue in this increasingly important area.

Introduction

The Weigher Standards section consists of integrated best practices, principles, and activities that provide comprehensive guidelines for achieving accuracy, repeatability and reliability for in motion weighing solutions and services. BWS defines the scope of the critical elements that lead to accurate, trustworthy weighing solutions.

This information will assist you in determining what is needed for your organization now, as well as practices that will keep your in-motion weighing equipment running efficiently and effectively in the future.

The Standards encompass all of the ingredients and processes involved in the provision of reliable, trustworthy in-motion weighing equipment including: site analysis, customer liaison, and consultation, review of options, specification, application design, installation, operation, maintenance, site audits, and trade certification options.

Goal of BWS

The goal of BWS is to provide guidance to bulk handling companies with in-motion weighing needs to help them to determine site requirements, specify, analyse and compare various options, understand the principles of and thereby ensure correct installation, and operational practice, and how to keep the equipment operating at peak accuracy for its service life.

BWS’s purpose is to create an environment where customers and in-motion weighing professionals can work together in an atmosphere of confidence based on common agreement with and competence in assessing the fundamental elements required for accurate weighing.

As part of this educational process, the BWS section contains interactive real time graphics illustrating common problem areas related to weighing, such as stockpile error and effectiveness. BWS promotes a logical approach to determining the best possible weighing accuracy for the particular application, from site analysis, through to ongoing service, maintenance and site auditting.

How to Use BWS

The BWS guidance consists of a series of key elements that are linked to the life cycle of the weighing equipment. These elements outline what is needed for successful in-motion weighing acccuracy and performance - from initial assessment, through the process of specifying and purchasing, ongoing maintenance and monitoring, and upgrades, all the way to the retirement of an outdated unit.
Key elements of Belt Weigher Best Practice standards include:

- Weighing theory
- Accuracy
- Error – Random and Systematic
- Calibration – Live Load, Static Mass, Electronic (Live Load Simulation), Chains
- Commissioning – Idler Alignment
- Location of weigher
- Belt Tension and Angle
- Frame Rigidity
- Maintenance
- Trade certification – the different International bodies, and analysis of  requirements
