With more than 165 years of engineering expertise, thyssenkrupp Polysius provides reliable and tailored solutions for mining and minerals operations. Our specialized services are designed to increase material flow without expanding the plant, improve equipment reliability, reduce downtime and extend equipment lifetime across the entire process chain.
Drawing on decades of experience in comminution, material handling and thermal processing systems, we provide audits, material testing, engineering services, spare and wear parts, repairs, reverse engineering, modernization projects and field services for minerals operations worldwide.
Our expertise includes polycom® high-pressure grinding rolls (HPGR), tube mills, crushers, apron feeders, kilns and drums as well as polab® laboratory automation used throughout mineral processing operations.
Legacy installations, fragmented systems or mixed equipment fleets are not a limitation but a starting point: we upgrade and support both our own equipment and third-party systems — from core components to wear parts, under one plan, with one partner.
Key Industry Trends
Increasing throughput without expanding the existing plant footprint
Reducing specific energy consumption across comminution circuits
Extending the operational life of existing production assets
Improving equipment reliability and plant availability
Reducing maintenance-related downtime and wear part costs
Modernizing aging and mixed-brand equipment fleets
Basing optimization decisions on measured process and material data
Optimizing lifecycle costs through targeted upgrades
With global experience supporting mining and minerals operations, thyssenkrupp Polysius helps producers maintain reliable production and maximize equipment performance throughout the asset lifecycle — for every ton, every kilowatt and every operating hour.
Optimization starts with understanding the process. Our service scope combines on-site investigation, laboratory testing and data analysis to turn measured conditions into concrete improvement measures.
On-Site Testing and Measurements
Specific grinding force, power draw, specific throughput and energy input
Adjustment of machine settings: spring curve parameters, chute width, hydraulic pressure and internal control loops
Sampling and particle size distribution analysis for screen efficiency evaluation
Functional checks of metal detectors and plant-specific operational challenges
Mechanical Inspection
Roller wear and condition assessment
Cheek plate check and adjustment
Feed chute dimensions and wear
Overall condition of the machine
Data Analysis and Evaluation
Determination of specific throughput, circulation factor and specific energy input
Comparison of laboratory versus industrial performance
Evaluation of screen efficiency and identification of system bottlenecks

Rethinking Everything Between the Rock and the Return
Smarter mining does not always start with a new machine. It starts with understanding the process — through audits that reveal what really holds back performance, and material testing that turns assumptions into data. When the right parts arrive at the right time and modernization follows a clear path, even complex mixed systems become an opportunity.
