Vertical Square Planetary Ball Mill with 0.4L-100L Capacity Stainless Steel Grinding Jars and Programmable Control

The XQM series with a vertical square design is a high-energy planetary ball mill where the main rotating disc (sun wheel) is oriented vertically and housed within a square or cubic-shaped machine body. This configuration provides greater structural stability, easier access to grinding jars, and enhanced efficiency for various grinding tasks, particularly with multiple jars.

• Stable Base: The square footprint provides a larger, more stable base that significantly reduces vibration during high-speed operation, crucial for grinding dense materials like metals and achieving consistent nano-scale results.
• Robust Construction: The square housing is made of strong, welded steel, making the machine durable and capable of handling the high stresses of planetary motion.
• Efficient Use of Space: The vertical orientation and square shape create a compact yet powerful unit, ideal for laboratories where bench space is limited.

The core principle involves grinding jars simultaneously revolving around a central axis (the vertical sun wheel) while rotating around their own axes in the opposite direction. This generates intense centrifugal forces, propelling grinding balls into high-energy impacts that crush, grind, and mix samples through friction and collision. This action is exceptionally effective for reducing hard materials like metal powders and abrasive materials like soil to micron or nano-scale fineness.

The machine's capability to grind everything from delicate soils to tough metal powders relies on using the correct jar and ball material to prevent contamination:

• For Metal Powders: Stainless Steel, Tungsten Carbide, or Zirconia jars are preferred for their high hardness, strength, and wear resistance, essential for mechanical alloying.
• For Soil & Geological Samples: Agate or Zirconia jars are ideal. Agate is exceptionally hard and chemically inert, preventing sample contamination for accurate elemental analysis.

• XQM-0.4L: Small benchtop model perfect for initial R&D and testing with very small sample sizes.
• XQM-2L/4L/6L: Standard laboratory workhorses for routine sample preparation.
• XQM-10L/12L/16L/20L/100L: Larger, often floor-standing models used for small-batch production or processing larger material quantities.

• Digital Display & Control: Precise setting of rotational speed (rpm), grinding time, and cycle patterns.
• Run/Pause Cycles: Programmable intervals of milling and rest to prevent excessive heat buildup, critical for heat-sensitive materials.
• Reversible Direction: Automatically changes rotation direction to ensure uniform grinding and prevent material caking.

• Mechanical Alloying: Creating novel, non-equilibrium alloys from blended elemental powders.
• Nano-Powder Production: Reducing metal powders to nano-scale to enhance sintering properties, catalytic activity, or for use in conductive inks.
• Dispersion and Mixing: Creating homogenous mixtures of different metal powders or metal-ceramic composites (cermets).

• Pulverizing Soil Samples: Grinding soil to a fine, homogeneous powder for accurate chemical and physical analysis.
• XRF/XRD Analysis: Preparing samples for X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD) by ensuring consistent and fine particle size for reliable data.
• Environmental Testing: Homogenizing soil samples to test for contaminants and pollutants.

• Grinding and mixing of ceramics, chemicals, pigments, and pharmaceuticals.
• Cell disruption in biological samples.
• Research in material science, nanotechnology, and chemistry.
