- SIDDHARTHA INDUSTRIES manufactures high-quality fabricated bleaching towers for the pulp bleaching process at both high and medium consistency levels in paper mills.
- Screened pulp often retains brown or blackish hues due to the presence of recycled paper and residual lignin content, which needs to be removed through bleaching.
- To achieve the desired whiteness, the pulp undergoes a bleaching process. Bleaching towers are used to facilitate both storage and the bleach reaction.
- Bleaching plants whiten paper through a series of three to five bleaching stages, followed by water washing, to enhance the brightness and cleanliness of the pulp.
- The tower is equipped with discharge scraper blades, ensuring uniform distribution of the material throughout the process.
- The scraper blades act as impellers, rotating with motor power for efficient mixing and distribution. Typically, the bleaching tower consists of three main parts: a cylindrical tower, an inlet at the top, and a scraper at the bottom.
- The pulp is processed inside the tower with bleaching chemicals at a controlled temperature, reaching up to 95°C for optimal results.
