Sizing Problems (Acidic, AKD, ASA, Rosin, Self-sizing, Size reversion, Variable sizing)The purpose of internal sizing is to resist the penetration or spreading of liquids through or on paper. The subject is complicated by the fact that there are several very different kinds of chemical treatments to make paper fluid-resistant, there are widely different kinds of liquids with which …
Friction is the difference in temperature of the feed entering the pellet mill die and the pellet being discharged from the die. The difference reflects the mechanical energy required to produce a pellet. There are several inherent factors that can affect friction: 1. Moisture addition to the feed ingredients.
Fluidized Bed Opposed Air Jet Mill. There are several factors that affect the working efficiency of the jet mill. 1. Material characteristics. Generally speaking, the jet mill can be adapted to the crushing of all brittle materials. However, due to the different properties of the materials, their crushing performance is also different.
