Abstract: The invention relates to a method for monitoring the wear state of the rolling surfaces of a high-pressure roller press in the course of comminuting, compacting, or briquetting material. The roller press has two rotationally driven press rollers, between which a rolling gap is formed with a gap width that can be modified during operation. One of the press rollers is designed as a stationary roller, and one of the press rollers is designed as a loose roller, wherein the loose roller can be positioned against the stationary roller via a force generating means with a gap width which can be modified during operation, and the outer diameter of the press rollers or the is reduced due to wear during operation. The method is characterized in that the position of the loose roller is recorded as a function of time using at least one position sensor, the position data is stored on a computer, and the wear state of the rollers is ascertained from the measured position data using an algorithm.

Abstract: The invention relates to a method for monitoring a high-pressure roller press in the course of comminuting, compacting, or briquetting material. The roller press has two rotationally driven press rollers, between which a rolling gap is formed with a gap width that can be modified during operation. During operation, operational data of the roller press is ascertained by one or more measurement value sensors and is stored on a computer. The method is characterized in that the operational data is stored as raw data on an edge computer, as an analysis computer, which is stationed locally in the region of the roller press and is connected to the measurement value sensors, and the raw data is evaluated on the analysis computer using an analysis algorithm so that characteristic data of the roller press is generated and stored on the analysis computer, wherein the characteristic data is transmitted from the analysis computer to at least one terminal via a wireless network and is displayed on the terminal.
