Centrifugal classifier for fly ash processing

Product catalog summary

Introduction
Metso Minerals Industries, Inc. provides a centrifugal classifier designed for processing fly ash, a byproduct of coal-fired power stations. This document outlines the specifications, benefits, and operational procedures of the Metso centrifugal classifier.

Fly Ash Specifications
Fly ash is categorized into Class C and Class F based on its characteristics. Class F fly ash, derived from higher-grade coals, is preferred for its pozzolanic properties. Key specification requirements include:

Loss on ignition: <3%
Combined content of SiO2, Al2O3, Fe2O3: ≥70%
Moisture: <1% (on-line feed)
SO3: ≤5%

Metso Centrifugal Classifier Features

Highly efficient in removing waste sizes, enhancing product yield.
Sharp separation capabilities with fine adjustment options to meet specific requirements.
No rotating parts, reducing wear and maintenance needs.
Ceramic linings provide outstanding wear resistance.
Operates with a single fan in clean air, minimizing power requirements.

Operational Procedure

Pneumatic transport of feed to the classifier.
Separation of coarse particles via centrifugal force.
Air stream passes through a particle curtain, drawing finer particles to a filter.
Secondary air inlet scrubs remaining particles, recirculating fines back to the primary flow.
Coarse particles exit through an air lock.

Applications and Installations
The Metso centrifugal classifier is used globally, with installations in countries such as Australia, Belgium, China, and the USA. It handles fly ash tonnages ranging from 40 to 100 tons per hour, adaptable to various requirements.

Conclusion
The Metso centrifugal classifier offers a robust solution for fly ash processing, providing efficient separation, low maintenance, and adaptability to specific site needs.

Centrifugal classifier for fly ash processing-2

Most accurate air classifier solution • Highly efficient removal of waste sizes • More product gained by the sharp separation the centrifugal classifier offers • No drop-off in separation as parts wear • Fine adjustment options allow separations to be tuned exactly to meet specification requirements Coal-fired power stations produce large volumes of waste product in the form of fly ash. When treated, this fly ash can have industrial applications. This is mainly due to its pozzolanic properties that can make it a suitable replacement for ordinary portland cement. Exceptionally low maintenance...
