Type Of Ball Used In Ball Mill Of Cellulose Fiber
Celluloid: The Eternal Substitute | Science History Institute
· Explosive fiber might seem an unlikely base for a moldable material, but the development of cellulose nitrate, also called nitrocellulose, was the first step toward celluloid. This "guncotton" could be dissolved with organic solvents, and the resulting thick, syrupy liquid, called collodion, dried to a flexible film or a hard sheet, depending on the proportion of solvent.
Nitrocellulose
In the production of nitrocellulose (NC), the raw cellulose must be in fibrous form prior to further chemical treatment. The raw material is prepared accordingly using CHM Hammer Mills. Before entering the hammer mill, the cellulose, in the form of web goods, is continuously fed via a speciallydesigned conveyor into a rotary beater, where it is separated into fibers with no bundling or knotting.

Ball mill
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
