Briquetting

Description

The research press is specially designed for researching the compactability or briquetting properties of fine-grained to powdery residues of all kinds. For this reason, care was taken in the construction of this special design by Rössner Maschinenbau GmbH to ensure that all important pressing parameters can be varied as much as possible.

The press not only offers the possibility of varying the pressing pressure, pressing duration or ejection speed of the cylinders almost at will, but also optional pressing from two sides or heating of the pressing bush and the feed material in the dosing hopper, among other settings. The press is also equipped with an automatic weighing and dosing device, which enables the series production of briquettes even with parameter variation. All pressing parameters can be continuously recorded and logged via the connected control system.

In a specially modified test press, the briquettes can be tested for strength either directly after successful briquetting or after artificial ageing, which is also possible. It is also possible to mix in a wide range of additives, such as binding agents or reducing agents, directly using the existing plant technology in the briquetting pilot plant.
