Vertical square planetary ball mill XQM-0.4-100L laboratory metal powder soil grinder

Stable Base: The square footprint provides a larger, more stable base, significantly reducing vibration during high-speed operation. This is crucial for grinding dense materials like metals and for achieving consistent nano-scale results.

Robust Construction: The square housing is typically 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 make it a compact yet powerful unit, ideal for laboratories where bench space is at a premium.

The core principle remains the same: grinding jars simultaneously revolve around a central axis (the vertical sun wheel) and rotate around their own axes in the opposite direction.

This generates intense centrifugal forces, propelling the grinding balls into high-energy impacts that crush, grind, and mix the sample 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. Their high hardness, strength, and wear resistance can handle the ductility and toughness of metals and are essential for mechanical alloying.

For Soil & Geological Samples: Agate or Zirconia jars are ideal. Agate is exceptionally hard and chemically inert, preventing contamination of the sample for accurate elemental analysis. Stainless steel can also be used if cross-contamination is not a primary concern.

XQM-0.4L: A small benchtop model, perfect for initial R&D, testing with very small sample sizes (e.g., a few grams).

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 quantities of material. The "100L" designation refers to the total volume of grinding jars the machine can accommodate, indicating an industrial-grade laboratory mill.

Digital Display & Control: Precise setting of rotational speed (rpm), grinding time (hours/minutes/seconds), and cycle patterns.

Run/Pause Cycles: Programmable intervals of milling and rest to prevent excessive heat buildup, which is critical for heat-sensitive materials and for maintaining the properties of certain metal powders.

Reversible Direction: Automatically changes the direction of rotation to ensure more uniform grinding and prevent material from caking on one side of the jar.
