What is EN ISO 21873-2:2018?

EN ISO 21873-2:2018 is a technical standard that provides guidelines and requirements for the testing of efficiency and performance of pulverizing equipment used in the processing of solid bulk materials. This standard is part of the ISO 21873 series, which covers various aspects of crushers and similar equipment.

Scope and Importance

The scope of EN ISO 21873-2:2018 includes both single-purpose machines and systems consisting of several machines for breaking, crushing, or grinding bulk materials. It applies to different types of crushers, such as hammer mills, impactors, or jaw crushers, used for size reduction of various materials like stone, coal, or cement clinker.

This standard is of great importance for manufacturers and users of pulverizing equipment, as it establishes common testing methods and criteria for evaluating their performance and efficiency. Compliance with EN ISO 21873-2 ensures that the equipment meets the necessary quality and safety standards.

Key Requirements

EN ISO 21873-2:2018 specifies the requirements for the determination of the following parameters:

Productivity: The capacity of the crusher to process a specific volume of material per unit time.

Reduction ratio: The ratio of the size of the input material to the size of the output product after crushing.

Electrical power consumption: The energy consumed by the crusher during operation.

Noise emissions: The level of noise generated by the crusher.

Dust emissions: The amount of dust released into the atmosphere during the crushing process.

Benefits and Application

EN ISO 21873-2:2018 provides numerous benefits for both manufacturers and users of pulverizing equipment. For manufacturers, compliance with this standard ensures that their products meet internationally recognized performance and efficiency criteria, enhancing their market competitiveness.

For end-users, the application of this standard enables them to compare different crushers objectively and make informed decisions based on reliable performance data. By using EN ISO 21873-2 compliant equipment, they can achieve improved productivity, reduced energy consumption, and enhanced environmental protection.

In conclusion, EN ISO 21873-2:2018 is an essential technical standard that sets out the requirements and testing methods for evaluating the efficiency and performance of pulverizing equipment. Its adoption by industry professionals ensures the production and use of high-quality crushers, benefiting manufacturers, users, and the environment alike.
