LC-GJK100-4 Sealed Sample Pulverizer, Four 100 g Bowls (CAT#: STEM-BC-4095-ZJF)

The LC-GJK100-4 is a four-bowl sealed pulverizer for increased sample-preparation capacity. It is applicable to coal, ores, rocks, nonmetallic minerals, and brittle metal samples. Four separate 100 g batches can be processed in one operating cycle. Each bowl uses a crushing ring and hammer to produce vibration grinding. The machine reduces feed below 13 mm to 120-200 mesh in less than three minutes. The resulting powder is uniform and can normally be used without sieving. Hydraulic lid support and quick-pressure locking improve operator access. The enclosed chamber reduces dust release and supports stable laboratory operation.
