Effective operation of the pulp machine can be extremely challenging.
The pulp machine is the final stage in the process for producing the specified end product in a pulp mill. The pulp slurry is drained on the 'wire' to create a continuous pulp web, and the wet web passes through a press section to squeeze out excess water before finally passing through a heated drying section. Effective operation of the pulp machine can be extremely difficult as there are many critical loops on a pulp machine that require accurate and reliable measurement and control. Basis weight, moisture content, stock flow, head box level, and vacuum and dryer temperature can result in an off-spec end product, or a sheet break and lost production.
