Grinding of cellulose in a ball mill was carried out during 10 h with a set of balls 10–30 mm in size. The grinding conditions: cylinder capacity 1 L, ball loading 330 mL, cellulose loading 330 mL, and rotating velocity 30–60 rpm. Cellulose was activated in an Aktivator-4M planetary mill (ZAO Aktivator, Novosibirsk, Russia).

25 hp. Size. 1500x2100 mm or 60x84 inch. Production Capacity. 5 TPH. The grinding process is performed either in dry or wet conditions. The drum mill can be operated either as a Ball or as a Rod Mill by using the corresponding module. A sufficient number of balls or rods is required for an effective grinding process.
Ball milling method was adopted to pretreat cellulose prior to the transformation. The ball mill machine is the Pulverisette P7 Premium Line (Fritsch) with a chamber (made of zirconium oxide (ZrO2)) volume of 45 mL and the balls (ZrO2) have a diameter of 5 mm. In the ball mill pretreatment, 0.5 g cellulose and an equivalent
12%The result revealed that the energy required by a ball mill, high-pressure homogenizer and twin screw extruder were 232.5, 43.3, and 5 kWh/kg of biomass, respectively . Kim et al. showed that a large amount of energy was needed by the planetary ball mill for grinding rice straw compared to the attrition mill.
Ball milling was carried out at 200 rpm over 4 h with 5 min of ball milling followed by 5 min of rest to allow for heat dissipation. The effective ball milling time was therefore 2 h. Eucalyptus cellulose was pre-ground for 1–2 min in a coffee grinder prior to ball milling. 2.3.
Phanthong et al. used a planetary ball mill to obtain nanocellulose with a yield of 93.1%. The obtained nanocellulose had a 10–25 nm diameter and a higher thermal stability . Veigel et al. pulped the beech waste and then fibrillated the pulp. Finally, the nanocellulose was obtained by a high-pressure homogenizer treatment.

During the ball …
Ball milling is another technique which was reported very recently for the production of NFC. In this method, a cellulose suspension is placed in a hollow cylindrical container, partially filled with balls (e.g., ceramic, zirconia, or metal). While the container rotates, cellulose is disintegrated by the high energy collision between the balls.
