The actual act of making a sheet of paper by hand requires a vat, mold and deckle. The vat is the container the pulp floats in. For most hobby makers, this will be your kitchen sink, a washing up bowl or a large plastic tank. You need a flat working surface nearby to place the wet sheets onto, and the whole working area needs to be splash-proof.
Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry process. In wet milling, water or alcohol commonly is used as the milling liquid.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball 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.
