Paper making machinery includes the preparation of raw materials, pulping, papermaking, and the production of finished products in rolls or sheets, as well as the processing of paper and paperboard
Now let the editor of Sichuan Guanbang Machinery Manufacturing Co., Ltd. introduce the pulping equipment of papermaking machinery to everyone
Pulping equipment is a type of equipment used to separate plant raw materials into fibers, belonging to the category of equipment accessories. The pulping methods can be divided into chemical method, mechanical method, and chemical mechanical method. The corresponding pulping equipment includes digesters, wood grinders, thermal mills, pulp washing machines, bleaching machines, beating machines, and waste liquid recovery equipment
The pulp produced by pre heating wood slices with steam and then grinding them under high pressure is called hot wood chip ground wood pulp. The machine used to manufacture hot wood chip ground wood pulp is a thermal mill, which consumes a lot of electricity. Therefore, fully utilizing the heat energy during the grinding process is the key issue of the thermal mill; A pulp washing machine is a mechanical device that separates digested pulp from black liquor. According to the extraction rate of black liquor, it can be divided into two categories: high concentration and low concentration extraction
The purpose of pulp bleaching is to remove residual lignin and pigments from the pulp after cooking, improve the whiteness of the pulp, and give the pulp a clean white color. Bleaching machine is a widely used bleaching equipment, which consists of components such as a spiral propeller of the bleaching pool and a washing drum. The slurry and bleach are placed in the pool and continuously added with washing water. With the help of a screw propeller, they circulate and flow in the pool, completing the process of mixing and chemical reactions. The water containing bleach products and residual bleach is discharged through the inner chamber of the washing drum, resulting in a clean white pulp
