Pulp Digester Ball
14C/25C/40C
Steam ball digester is an important equipment in papermaking and pulping process.
Raw material cooking: put papermaking raw materials (such as wood, reed, straw, etc.) together with chemicals (such as caustic soda, etc.) into the steam ball, and cook it under high temperature and high pressure environment. The lignin and hemicellulose in the raw material are separated from cellulose to provide pure fiber raw material for subsequent pulping.

Pulp digester for paper making
Pulp digester paper mill is an important for papermaking and pulping process.
- Softening raw materials: High temperature pressure conditions can destroy the structure of raw materials, making the fibers soft.
- Impurities Removal: During pulp digester paper mill, resin and grease in raw materials will be dissolved to improve purity of paper pulp.
- To lay foundation for follow-up: Fibers separated from the raw materials by tissue digester paper mill meet the requirements of washing, screening, washing, screening, and bleaching, improving the quality of paper.

Structure and principle of pulp digester paper mill
Pulp digester is a type of rotary intermittent steam ball tissue digester paper mill equipment.
Itis spherical and mainly composed of ball digester, machine base, transmission device, and others.
The steam ball pulpdigester paper mill is made of welded or riveted steel plates. There is a loading hole at the vertical centerline position of the steam ball pulpdigester for loading raw materials and chemical liquids. Introduce heating steam and discharge condensed water from the neck of the hollow shaft.

Advantages of tissue digester paper mill：
1. The raw materials inside steam ball are thoroughly mixed with medicinal solution, and the quality of paper pulp is relatively uniform
2. Low liquid ratio and high concentration of medicinal solution can shorten digesting time
2. Low liquid ratio and high concentration of medicinal solution can shorten digesting time
3. The tissue digester paper mill is simple, requires minimal investment, and is easy to manage and maintain.
