1. The Influence of Temperature 

With the  increase of temperature, waste paper is soft, slurry easy to absorb water and pulp, especially those hard sized paper or printing paper with ink. In addition, the viscosity of the pulp decreases with the increase of temperature, and has good fluidity, thus promoting the circulation of pulp and improving the breaking effect.

2. The Influence of Consistency

It is of advantage to increase the pulping concentration in the case of ensuring good circulation of slurry. From the experiment we know that the concentration has a linear relationship with the power consumption, but the energy consumption per unit yield decreases with the increase of concentration, but has little influence on the pulping and pulping time.

3. The Influence of Pulping Time

Under certain operating conditions, there must be an effective interval of breaking.  If exceeds the interval, the increase of the rate is very small. It is not economic if we attempt to extend the time to improve the disintegration effect. Therefore, breaking timemust be controlled so that it can be operated within a valid time frame.

4. Influence of material properties 

Because of the different water absorption, swelling ability and fiber binding capacity of the treated pulp, the effect of fragmentation is different.
