Used for pulverizing, mixing and homogenizing 10 to 500 gram samples sizes, this swing mill grinder reduces samples to 100 to 400 mesh. A maximum sample of 13 mm is placed in a grinding container with a puck and ring. Once the container is covered and installed in the grinder, vibration action reduces the sample. A manual self-adjusting clamp maintains sealing pressure to prevent sample loss during grinding. Applications include wet and dry productions samples, mineral, soil, rock, cement and glass. Manufactured with a steel frame and sound dampening lining; includes control panel with an emergency button.
