Category: SAMPLE PREPARATION

For efficient dry or wet grinding of brittle and very hard samples to analytical fineness. Most suitable for "XRF" "XRD" and "AA" sample preparation.

PRINCIPLE OF OPERATION
Grinding is done by heavy impact and friction. Sample is kept in the annular space between the bowl, ring and the puck. A cover is kept on the top of the bowl then the bowl is clamped on vibratory platform and subjected to heavy vibrations. The vibratory platform imparts the kinetic energy to the ring and the puck.

FEATURES
• Extremely fast grinding by impact and rubbing of trapped material under the grinding ring and puck.
• Analytically pure grinding without any loss of material.
• Reproducible grinding.
• Dry as well as wet grinding is possible.
• Start & Stop Push button, Motor overload protection with door safety system and fault indication lamps are provided.
• Soundproof enclosure facilitates noise below 71db during operation.
• One year warrantee against any manufacturing defects.
