elements. Smaller grinding containers and those made with ceramics have a puck-

Typical samples include cements, soils, ceramics, slag, rocks, and ores, but the
8550 ShatterBox has also ground sulfur pellets, dried marsh-grass,
pharmaceuticals, and many other materials. To maximize grinding capability and
