High-Pressure Grinding
The energy-efficiency of crushing and grinding processes is becoming an increasingly important issue for the cement industry. More than half the energy consumed in the industry is used in crushing and grinding operations.
One of the main benefits of high-pressure comminution is the reduction in energy requirements when compared with conventional crushing and grinding methods. When applied in combination with roller press technology, the resulting high-pressure grinding roller (HPGR) circuits offer many potential economic advantages in comparison to equivalent vertical roller or ball mills, such as:
High-pressure comminution technology has gained popularity steadily since the 1980s and today HPGR machines are regarded as state-of-the-art technology in the cement and related industries. And the list of applications continues to expand in these industries as increasing costs of electrical energy, coupled with the worldwide initiative to reduce CO2 emissions, means that this energy-efficient technology will become indispensable for the cement-making process.
Wear Protection
The adoption of high-pressure comminution technology has led to significant energy savings as well as reduced costs for wear material. But the conventional welded rolls used predominantly in the past in HPGRs were subject to rapid and excessive wear.
Köppern has responded to this challenge by developing the unique HEXADUR® and HYBRIDUR® wear protection systems for use in high-pressure comminution processes. Read more about wear protection
