Trommel screen WikipediaLapis Lazuli The blue gemstone lapis lazuli information
A trommel screen also known as a rotary screen is a mechanical screening machine used to separate materials mainly in the mineral and solid waste processing industri It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end Physical size separation is achieved as the feed material spirals down the rotating drum where the undersized material Lapis Lazuli is a deep blue opaque gemstone used in antiquity and continuously used throughout the generations It still continues to be popular today and remains one of the most important opaque gemston Lapis Lazuli is chiefly composed of the mineral Lazurite with additional other minerals including white Calcite and sparkling specks of
