Secondary Crushing
Further material size reduction to achieve consistent intermediate sizing for optimal screening and accurate product classification.
Service Overview
Consistent Sizing That Sets Up the Screen
Secondary crushing systems further reduce coal to intermediate sizes suitable for final screening and classification. This is the stage that determines how cleanly the downstream screens can separate product — inconsistent feed here means inconsistent fractions later.
Our secondary circuits are configured to hit tight, repeatable size targets while minimising the generation of excessive fines, protecting both product quality and saleable yield across domestic, export and power-generation markets.
- Consistent intermediate sizing for optimal screening
- Minimised fines generation protects saleable yield
- Oversized material automatically recirculated
- Configured to meet client and market specifications
What’s Included
Precision at the Second Stage
Equipment, monitoring and controls configured to deliver repeatable intermediate sizing shift after shift.
Coal Sizers
Twin-roll coal sizers reduce material to precise intermediate dimensions with controlled, low-impact crushing action.
Roll Crushers
Purpose-built roll crushers handle secondary reduction while preserving lump integrity and product quality.
Recirculation Loops
Oversized material is automatically returned for further crushing, keeping product within specification.
Fines Control
Crushing parameters are tuned to limit excessive fines, protecting saleable yield and product value.
Process Optimisation
Continuous monitoring and process optimisation maintain equipment availability and operational efficiency.
Safety & Compliance
Zero-harm philosophy and MHSA-aligned procedures govern every aspect of secondary crushing operations.
How It Works
From Primary Feed to Screen-Ready Product
A closed-loop sequence that keeps material within specification before it reaches the classification decks.
Feed from Primary
Coal reduced during primary crushing is conveyed into the secondary circuit at a controlled, consistent feed rate.
Intermediate Reduction
Sizers and roll crushers reduce material to consistent intermediate sizes suitable for final screening and classification.
Recirculate & Verify
Oversized material is automatically recirculated for further crushing while in-spec product moves on to screening.
