Small Vertical Ball Mill Laboratory XQM Planetary Ball Mill Rapid Four-cylinder Agate Grinding Machine

XQM: This is a common model series designation used by various manufacturers, particularly from China. It identifies a specific line of planetary ball mills with known performance characteristics and a standardized design.

Planetary Ball Mill: Confirms the core technology, which uses high-energy impact from balls inside rotating jars to grind materials.

Small Laboratory: Reinforces that this is a benchtop instrument for R&D, processing small batch sizes (typically 0.1g to 100g per jar).

Small Vertical: Describes the physical orientation. The central axis of the mill is vertical, which often results in a more compact footprint and a lower center of gravity compared to some horizontal designs, saving lab space.

This indicates a high-power motor capable of achieving high rotational speeds. The "planetary" motion already enables fast grinding, and a "rapid" model is optimized to reach these high speeds efficiently, significantly reducing processing time to achieve the target fineness.

Cylinder: In this context, refers to the grinding jars or pots.

Four-Cylinder: Specifies that the mill has four grinding stations. This is a key feature for:

• High Throughput: Processing up to four different samples simultaneously.
• Experimental Consistency: Ensuring all samples are ground under identical conditions (same speed, time, and environment), which is critical for comparative studies.
• Efficiency: Drastically reduces the time needed to prepare multiple samples.

Agate: This is a natural silica-based mineral (SiO₂) known for its high hardness (~7 Mohs) and exceptional chemical purity.

Significance: Specifying "Agate Grinding" means the mill is equipped with agate grinding jars and agate grinding balls.

Primary Advantage: Extremely Low Contamination. Agate is ideal for preparing samples for trace element analysis (e.g., by ICP-MS) or in applications where introducing metal ions from stainless steel jars would ruin the experiment (e.g., in geochemistry, ceramics, or certain catalyst preparations).

Consideration: Agate is slightly less hard and durable than sintered Zirconia, so it is best suited for hard but not extremely abrasive materials.
