Batching tank for coatings
Level

Overview
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 paper web to tear or split in the machine. The coating agent is mixed with hot water in a batching tank at a temperature of 50 °C, and pumped to various points in the machine. To maintain automatic operation, the level in the batching tank must be measured and the filter status monitored continuously.
