HPGR Case Study: 78% Copper Throughput Gain with HSM G1280

Project Overview

This HPGR case study examines a major copper mining operation that was facing high recirculation loads and liner wear issues in their tertiary crushing stage. HSM replaced their existing cone crushers with the G1280 High Pressure Grinding Roll, significantly improving overall plant capacity.

High Pressure Roll Mill

Key Results

Metric	Before HSM	After HSM HPGR
Plant Throughput	~320 t/h	570 t/h (+78%)
Liner Wear CostHigh	High	Reduced by 55%
Moisture Tolerance	<4%	Up to 9%

“Switching to the HSM HPGR eliminated our bottleneck stage, increased grinding circuit stability, and cut wear part replacements from monthly to quarterly intervals.”
