Description: We know the crushing effect is very important for the quality of material products, thus, it is necessary to adjust the crusher and material, because all of this can make preparations for the crushing of double roll crusher. The models of double roll crusher, moisture content of material, proper roller gap and many other aspects will influence the crushing effect.

A similar trend of amorphization can be seen in the case of rotor milling. Once more, this could suggest some mechanical degradation though not to a significant extent. Final crystallinity calculated from the second thermal run expresses a deviation of 3. Here, the cold crystallization peak at 137. It is well known that mechanical milling can induce amorphization [3]; Ishida et al. [31] studied these effects on Polytetrafluoroethylene (PTFE) and polyethylene (PE) and Castricum et al. Though the milling process only takes up a fraction of seconds, the powders are subjected to multiple treatments to further reduce the particle size, which could have a cumulative effect on degradation behavior.4% from the untreated material. [32] confirmed these findings by their research on high-density polyethylene (HDPE).7 °C can be attributed to amorphization due to the mechanical treatment.

The specific surface area of the active materials is closely related to the formation area of the electric double-layer. Microporous ACs with a narrow width of2 nm can produce a wide electric double-layer and thus give the electrode a high specific capacitance [14,15,16,17]. ACs with a specific surface area of3000 m2 g−1 are now available on the market and can be employed as the electrode active material. The advantages of EDLCs are high-power density and long cycle-life, when they were compared to secondary batteries. Those provided a very high gravimetric specific capacitance of 209–575 F g−1 under the use of aqueous electrolytes [6,10,11] and that of 144–338 F g−1 under the use of nonaqueous electrolytes [5,12,13]. Highly porous carbons, whose specific surface areas are3000 m2 g−1, have been produced from various precursors and via novel chemical activation techniques [5,6,7,8,9]. The charge–discharge processes with high-power density are based on a principle of physical adsorption and desorption of electrolytic ions onto the electrode, so as to allow the formation and release of the electric double-layer. In addition to the specific surface area, the pore size distribution of ACs is also an important factor determining the capacitive and resistive behaviors of EDLCs.Electric double-layer capacitors (EDLCs) are energy storage devices that have been applied to various energy storage sectors such as automobiles, power leveling for renewable energies, and portable electronic devices [1,2,3]. Activated carbons (ACs) are mainly employed as the active materials of EDLC electrodes due to their high specific surface area, excellent cost-performance, and large-scale productivity [4]. ACs with a high specific surface area are very effective in increasing the gravimetric energy and power density of EDLC electrodes.
