Condition monitoring of roller press components allows for effective maintenance planning and repair, thereby minimising downtime as well as preventing unexpected failures and unscheduled stoppages. The Dalog online condition monitoring system for roller presses detects failures at the motor bearings, gearboxes and grinding rolls at an early stage.

A summary of the design and operating variables of the pilot-scale roller press in the campaigns is given by Table 1. The first campaign was primarily dedicated to assess the performance of the HPGR at different pressures, namely from 0.5 to 5 N/mm 2 of specific force, as well as different roll velocities, namely from 0.2 to 0.9 m/s. The second ...

The use of high-pressure grinding machines in minerals processing plants requires special attention to the following issues: Evaluation of ore performance and assessment of …

Roller presses developed for grinding a range of raw materials, are often used in the cement industry for grinding limestone (raw meal), cement clinker and blast furnace slag. The roller press can work together with a …

The cement roller press is a type of material-crushing machine which is often used in cement plants. It usually works together with a ball mill to form a pre-grinding or final-grinding system for the grinding of raw materials, coal, and clinker.. Compared with the traditional tube mill and ball mill, the roller press has lower energy consumption and …

Abstract. This paper details the development of a functional work index that characterises the relationship between the energy that is imparted by a Roller Press into materials, against the resultant size reduction achieved. Such a Roller Press work index is necessary for this new grinding technology to differentiate it from Bond`s grinding ...

Finding failure. By ICR Research. Published 06 September 2017. Roller presses are a popular choice for raw, pre-clinker or finish grinding. Online condition monitoring of its components can help detect early equipment failure and reduce downtime of the grinding section. By Dalog Diagnosesysteme , Germany.

Main drive and frame assembly for Hydraulic roller press 3.00 are given below. Roller : The roller is one of the major components that play a major role in the roller press during the grinding of clinker material. The roller is one of heaviest components in the roller press. The roller has been manufactured by means of forging process.

Van der Meer and Schnabel (1997) also described some of the specific features of the roller press and the effect of roller press grinding on the energy consumption of subsequent ball milling. Their results with various ores showed that a reduction in grindability by high-pressure grinding rolls can be demonstrated both on lab …

With the continuous development of grinding technology, there are two kinds of cement grinding equipment with lower energy consumption, one is vertical roller mill, and the other is roller press. The two types of equipment are different in grinding mechanism, structure design, and product performance, but each has its own advantages. 1.

The roller press is often used where energy-efficient grinding of large product quantities is required. The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles by causing micro cracks, so that the subsequent fine grinding is easier.

Roller presses grind thousands of tons of material, day after day, all year round. Unsurprisingly, this causes progressive wear, especially of the roller surfaces. In abnormal circumstances, it can also result in more significant damage to the roller itself. The Roller Press Scanner detects both. Current status is then automatically reported against …
