XPM-Φ120×3 Three Head Grinding Machine Laboratory Mineral Sample
Pulverizer
The XPM-Φ120×3 Three Head Grinding Machine is a professional
laboratory sample preparation equipment designed for fine grinding
of mineral, geological and industrial materials. This machine
features a three-head grinding structure that allows three samples
to be processed simultaneously, significantly improving laboratory
testing efficiency.

Key Features
- Three Grinding Heads Design: Processes multiple samples simultaneously for improved laboratory
efficiency
- Uniform Grinding Performance: Optimized grinding structure ensures consistent sample fineness
and analysis accuracy
- Professional Laboratory Application: Specifically designed for mining, geological exploration,
metallurgical testing, chemical analysis, and scientific research
- Stable and Reliable Operation: High-quality motor and transmission system provide smooth
operation with low vibration
- Compact Structure: Small footprint suitable for laboratories with limited working
space
- Easy Operation and Maintenance: Simple operating process with convenient cleaning and component
replacement
Working Principle
The XPM-Φ120×3 three head grinding machine operates through
interaction between grinding bowls and grinding media. After sample
entry, the motor drives the grinding mechanism to rotate. Under
combined effects of pressure, friction and impact force, material
is gradually crushed and ground into fine powder. The three
grinding heads operate simultaneously to achieve efficient and
uniform sample preparation for laboratory testing and analysis.
