Описание (английский):

This document describes the principles and methods for the expression of results of performance tests on sizing equipment used in coal preparation and includes methods for the evaluation of performance parameters. Performance test procedures and size measurement techniques are recommended. This document applies to all types of sizing equipment, categorized as follows: a) screens; b) classifiers; c) others. The procedure described in this document applies to two-product separations. Performance assessment of multiproduct separations can be achieved by consideration of a series of two-product separations.

Overview

ISO 10752:2025 - "Coal sizing equipment - Performance evaluation" specifies principles and methods for expressing and evaluating the results of performance tests on coal sizing equipment used in coal preparation. It covers recommended performance test procedures, size-measurement techniques and methods for evaluating performance parameters for all types of sizing equipment (screens, classifiers and others). The standard applies to two‑product separations (multiproduct separations can be assessed as a series of two‑product tests) and includes worked examples for common equipment types.

Key topics

Scope and classification: Applies to screens, classifiers and other sizing equipment used in coal preparation.

Performance criteria: Defines the essential criteria to report - feed rate, reference size, sharpness of separation, misplaced material, placement efficiencies, degree of difficulty and material characteristics.

Performance parameters: Standardized parameters such as partition size, equal‑errors size, theoretical yield, material placement efficiencies (coarser and finer), overall separation index, and sharpness of separation (probable error).

Test procedures: Guidance on determining feed and product mass/flow (direct weighing, calibrated conveyors/flowmeters, timed increments), handling recirculated material and ensuring uniform test conditions.

Sampling & analytical methods: Sampling recommendations in accordance with the normative references (see Related Standards) and procedures for size analysis and moisture correction to report results on a dry basis.

Data evaluation & presentation: Methods for reconstructing feed size distribution, drawing partition curves, misplaced material curves, calculating partition/equal‑errors sizes, theoretical yields and tabular/graphical reporting.

Worked examples: Annexes include examples for a vibrating screen, cyclone and deduster to illustrate application of procedures.

Applications and who uses it

ISO 10752:2025 is practical for:

Coal preparation plant operators - to benchmark and document equipment performance and optimize process settings.

Equipment manufacturers - to provide standardized performance claims and acceptance test procedures.

Test laboratories and consultants - to perform repeatable, comparable performance evaluations.

Procurement and quality assurance teams - to compare sizing equipment objectively during selection and commissioning.

Regulators and auditors - to verify compliance with recognized testing and reporting methods.

Benefits include consistent performance reporting, reliable comparison between technologies, better prediction of separation results and reduced ambiguity in test reports.
