ABSTRACT: Roller presses are commonly utilized in the processes of compaction, briquetting and comminution
of bulk materials across various fields of mineral processing. For each individual process, set points and operating
parameters such as compression force, speed of the rollers and control of the feeding system can be optimized
within the running system. This flexibility allows for increased process control and performance. Modern presses
are equipped with numerous sensors, which are used for Industrial Internet of Things (IIoT) applications.
In this paper, some typical examples for roller press applications and their corresponding IIoT-related digital
helpers are detailed.
INTRODUCTION
Roller presses are used in various fields of mineral process-
ing, such as: comminution of cement and ores, hot and cold
briquetting or for compaction of various types of fertilizers.
Depending on the machine size and application, the mass
throughput ranges anywhere from 100 kg/h for laboratory
scale pharmaceutical applications (Herting 2007), to 100
metric t/h in potash applications and up to 3,000 t/h in the
case of the largest high-pressure grinding roll applications
(Klymowsky 2002). An example of a modern roller press
for cement clinker grinding can be seen in Figure 1.
Irrespective of the field of application of the roller
press, the main components remain the same. They consist
of two horizontally mounted and counterclockwise rotat-
ing rolls, of which one is designated as a fixed roll and one
as a floating roll. Pressure is applied by hydraulic pistons to Figure 1. Example for a roller press in comminution -HPGR
