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.

Pipeline design consideration and standards

· The pressure and temperature requirements, and the chosen wallthickness calculation formula, dictate the resulting pipe wall thickness required for the piping or pipeline design. The specifiion and grade of pipe and fitting materials selected for the design must be compatible with each other chemically (, carbon content) so that the fittings can be welded to the pipe.
