The final goal of paper making is to produce qualified paper, improve the extraction rate, reduce the consumption is the purpose of every paper mill.
The pulping process is a process of continuous dilution and enrichment, so the pulp concentration depends on the technological conditions and equipment, not each equipment is requires a higher concentration. Without affecting the quality of pulp, the higher concentration the better, this can reduce the load of the quality pulp of the equipment, then save energy.
1. The concentration of high concentration bleached pulp is 25-30%;
2. The concentraion of medium concentration beating pulp is 6-12%;
3. The concentraion of high concentraion beating pulp is 20%-30%, called high consistency refining.
