Detail Produk
GRINDING EFFICIENCY
Due to the planetary-centrifugal nature of the bowl rotation, the grinding balls and particles of the crushed material in the bowl are accelerated up to 30g, which ensures effective sample grinding.
EASY MAINTENANCE
Folding cover for quick access to the bowls.
Bowls fastener with adjustable latch.
EFFECTIVE NOISE INSULATION
Soundproofing lining inside the cover and on the entire inner surface of the casing.
OPERATIONAL SAFETY
The end switch prevents the grinder from starting with cover open.
BELT DRIVE
The toothed drive belt ensures high reliability and low noise.
SIMULTANEOUS GRINDING OF 4 SAMPLES
Simultaneous grinding of four samples up to 45 cm3 each, total sample volume up to 180 cm3.
Possibility of grinding material in four bowls or in two opposite ones;
BUILT-IN TIMER
The built-in timer allows setting the operating time and automatically stopping the mill.
QUALITY WORKING BODIES
The bowls are made of tool steel (5140H). Polishing of the bowl, lid and balls minimizes contamination of the sample with particles from previous samples and facilitates cleaning.
