1. Basic Principles of an Air shaft An airshaft or air expanding shaft works by pumping its internal air shaft bladder which pushes out the external gripping teeth/panel/rubber to hold onto the materials from their core. By releasing the air, the gripping medium un-grips the materials, allowing easy replacement.

Principles and Advantages of Pyrolysis - MoreGreen

Rubber will pyrolyze some chemicals with immense molecular weight. Therefore, the oil at this time is dark and sticky. Above 300 C, the decomposition rate of rubber is significantly accelerated, and the molecular weight of the pyrolyzed chemical substances is small. The bio-oil obtained at this time has good flowability, and the color ...
