Bleach tower
Valmet BleachBin is a tower for bleaching pulp at both high and medium consistency. A discharge scraper placed in the bin bottom ensures optimal material distribution.
The bleach bin is a tower for bleaching pulp at high consistency (>25%). A discharge scraper placed in the bin bottom ensures optimal material distribution.
The chemical mixer screw discharges the pulp at around 25-30% consistency to the top of the bleach bin. The bleach bin consists of a pulp inlet at the top, cylindrical tower and a discharge scraper. The tower is equipped with load cells or a radioactive level control system.
The discharge scraper is driven by a frequency-controlled AC-motor via a planetary gear unit and is sealed with a stuffing box.
