Re: design of baryte machine

"Barite is the main ore of barium. It is also important in the manufacture of paper, glass, rubber. A rich, white pigment is made from crushed Barite. Barite is also used in radiology for x-rays of the digestive system. When crushed, it is added to mud to form barium mud, which is poured into oil wells during drilling."
