The acceleration of these chemical reactions is promoted by the processes of the activation of the mixtures of solid components (an increase of the interface, accumulation of defects, amorphization, an increase in free energy). High temperatures and pressure arising during mechanical treatment can also create unusual conditions for chemical reactions. An intense mechanical action on heterogeneous systems containing liquid leads in some cases to the occurrence of hydrothermal conditions and cavitational processes in local regions [26].

In the case of lignin-containing materials, the disordering of cellulose crystallites causes an increase in the rate of reaction and contributes mainly to the total yield [47]. The next important parameter responsible for the reactivity of lignocellulose is the specific surface area of the material. The fine grinding of dry plant raw material allows one to increase the rate of the initial (heterogeneous) stage of the subsequent acidic or enzymatic hydrolysis of the polymers present in the cell walls [11,42,43,48e51].

This problem may be partially solved by increasing the geometric size of the mills to a huge scale. Thus manufacturers usually declare a tumbling mill with a maximum size of about 5 m in diameter and 15 m long, with an energy consumption of about 4 MW. The productivity of this equipment with respect to sand is about 120 tons per hour. 10 Types of ball movement in a planetary mill: (A) rolling over, (B) falling, (C) rolling running. 40 Chapter 2 necessary time of mechanical treatment increases by a factor of 2e3, so the productivity decreases generally to 15e5 tons per hour.
