Paper Industry
The paper industry involves complex processes from pulp preparation through forming, drying, and finishing. Precise level and pressure measurement handles foaming, buildup, and varying densities while optimizing fiber recovery and energy efficiency.
Overview
The paper industry involves complex processes from pulp preparation through paper forming, pressing, drying, and finishing. Each stage presents distinct instrumentation challenges, from measuring wood chip levels in digesters to monitoring chemical concentrations in bleaching processes. Level measurement in stock chests, chemical storage tanks, and coating vessels must handle foaming, buildup, and varying material densities. Pressure monitoring across refiners, presses, and steam systems is essential for maintaining product quality and energy efficiency. Modern paper mills increasingly rely on precise process control to optimize fiber recovery, reduce water consumption, and minimize energy use while meeting demanding product specifications.

Ash silo
Paper Industry
Large quantities of fibre waste are produced during paper production. These are dried and burned and the energy released during combustion is used as process heat or to generate electricity. The ash i...
Batching tank for coatings
Paper Industry
The press rolls are cleaned during product changes or shutdowns of the paper machine and then treated with a special coating agent. This protects them from adhesions and deposits that could cause the...
Bleaching tower
Paper Industry
In order to achieve the desired degree of whiteness, the pulp must be bleached. For this it is filled into the 25 meter high bleaching tower. The bleaching process runs continuously at temperatures...
Cleaner
Paper Industry
Cleaners remove contaminating materials that are specifically heavier than fibres. In waste paper processing, these contaminants are, for example, sand, glass, stones or staples. The feed through the...
Deaerator
Paper Industry
The approach flow system connects the stock preparation facility with the paper machine. Here, the pulp for the paper machine is diluted to the required consistency. Additionally, the approach flow sy...
Digester
Paper Industry
In the digester, the action of chemical dissolution removes the lignin binder, thereby exposing and freeing the cellulose fibres. During the cooking process according to the alkaline sulphate method,...
Drying-cylinder
Paper Industry
The residual moisture content of the paper web is removed by steam-heated cylinders in the drying section of the paper machine. The drying process removes heat from the steam, which then forms a thin...
Dump chest
Paper Industry
The fibre suspension created in the pulper is first drawn off into a dump chest. There it is temporarily stored for the further stages of the stock preparation process. Typical process challenges in t...
Headbox
Paper Industry
The paper suspension is pumped into the headbox of the paper machine. Via the hydraulically pressurized headbox it passes through a tapered cross-flow distributor and manifold, through the rectangular...
