Comminution testing to reduce risk

Comminution testing for optimal sizing and planning

We know your crushing, grinding, blending and splitting equipment represents significant operational and capital costs. Accurate comminution testing reduces the design risk associated with comminution circuits. That’s why we offer a comprehensive range of comminution testing to determine the ideal plant parameters that will optimise your processing plant.

FLSmidth's Comminution Lab offers all testing components for equipment sizing, and we thoroughly train our staff in testing procedures to ensure consistency and accuracy.

We provide:

Bond Crusher Work Index
Bond Abrasion Work Index
Bond Ball/Rod Mill Indices
J-K Drop Weight Test*
SMC Test®*
Starkey SAG Design Test*
Starkey SAG Variability Test (SVT)*
Unconfined Compressive Strength (UCS)
HPGR
VXP

*Licensed to conduct this test work at our facility, data is interpreted and results reported by the parent company.

P150 High-Pressure Grinding Roll

The FLSmidth P150 High-Pressure Grinding Roll (HPGR) sizing machine is used for all initial HPGR lab-scale test work. The pilot-scale crusher is designed to process ore in the identical manner of an industrial unit, as it employs the exact same breaking mechanism. We have determined that the P150 HPGR is the minimum size applicable to provide accurate data for scale-up.

VXP10 Mill

The FLSmidth VXP10 vertical stirred mill offers ultra-fine grinding capabilities. A pendulum grinding test in this mill determines the residence time and energy input to achieve a specific size reduction, based on progressive sizing reduction as the material passes through the VXP10. Test results can then be used to determine the operating parameters for full-scale production mills.
