Ball milling: a green technology for the preparation and
Milling was then performed in 80% ethanol for 30–120 minutes using a high-energy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intra-fibre swelling.

Manufacturer & Supplier of Rubber Sheet in the Philippines
The manufacturing process of a rubber sheet can be divided into three main steps: vulcanization, calendering and cutting. Vulcanization is a process of heating the rubber to create a cross-linked network of molecules, which gives the rubber its strength and elasticity. Calendering is the process of rolling the vulcanized rubber into a thin sheet.

Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
