Portable Ore, Soil & Rock Pulverizer for Mining, Exploration & Handheld XRF Analysis

The Alloy Geek Portable Rock Pulverizer is a compact, field-ready solution for preparing geological samples for handheld XRF analysis in mining and mineral exploration environments. Designed for rapid, dry pulverization of rock, soil, gravel, and ore, this system enables consistent, repeatable sample preparation directly in the field, reducing reliance on lab turnaround times.

This custom, German-made design is engineered for durability, portability, and precision—making it ideal for gold, silver, copper, iron ore, and polymetallic exploration workflows where fast, defensible XRF data matters.

Designed for Handheld XRF in the Field

Handheld XRF performance is highly dependent on sample homogeneity and particle size. The Alloy Geek Portable Rock Pulverizer allows exploration teams to:

• Reduce sample heterogeneity
• Improve repeatability between measurements
• Minimize surface bias and coarse-grain effects
• Generate more defensible, lab-correlated XRF results

This system is purpose-built for field sample preparation, not hobby crushing or wet milling.

Sample Capability & Performance

• Maximum feed size: Up to 1 inch (smaller material processes faster and more uniformly)
  • For larger rocks, simply break them up with a crusher or hammer before placing them inside the pulverizer!
• Typical sample volume: ~1 cup of material
• Materials processed:
  • Rock
  • Ore
  • Gravel
  • Sand
  • Dry soil
• Mohs hardness: Up to 8 (quartz)
• Typical run time: ~30 seconds per sample
• Pulverization method: Dry grinding (no additives or liquids required)

This makes the system ideal for rapid preparation of exploration-grade samples prior to handheld XRF measurement.

Hardened Blade & Drum System

• Specialized hardened steel blades designed for abrasive mining materials
• Sealed stainless steel drum prevents sample loss and cross-contamination
• Hand-screw lid closure ensures secure sealing during operation
• Optimized for consistent particle reduction suitable for XRF analysis
• The sealed design supports cleaner operation and safer handling in field conditions.
