ZOLI Planetary Ball Mill Machine with 800 rpm Speed, 10 mm Grinding Balls, and Digital Control for Laboratory Material Grinding

Dual Rotation System: Each grinding jar mounts on a rotating disk (planet). The main disk (sun wheel) rotates, causing all jars to revolve around the central axis while a gear mechanism forces each jar to rotate on its own axis in the opposite direction.

Centrifugal Forces: This counter-directional movement generates Coriolis and centrifugal forces multiples of gravity. Grinding balls inside the jars are flung against inner walls, impacting and grinding material through high-energy collision and friction.

Material Options for contamination prevention and specific applications:

• Stainless Steel: General purpose, high strength
• Agate (SiO₂): Contamination-free grinding of hard, abrasive materials; chemically inert
• Tungsten Carbide: Extremely hard and wear-resistant for very hard materials
• Zirconia (ZrO₂): Excellent wear resistance, high density for high-energy impact, good chemical inertness
• Nylon, Teflon (PTFE): Metal contamination avoidance and soft material processing
• Polyurethane: Specific chemical resistance applications

Sizes: The XQM series supports jar sizes from 50ml to 1L to match machine capacity and flexible batch requirements.

• Digital Display: Clear LCD/LED screen for parameter setting and monitoring
• Programmable Operation:
  • Grinding Time: Adjustable from seconds to hours
  • Rotation Speed: Variable control (100-800 rpm) for impact energy management
  • Run/Pause Cycles: Alternating milling and rest periods to prevent overheating
  • Reversible Direction: Automatic rotation direction alternation for uniform grinding

• Safety Interlock: Prevents operation unless protective cover is securely closed
• Emergency Stop Button: Immediate shutdown capability
• Vibration & Noise Dampening: Sturdy construction with damping systems for stable operation
• Overload Protection: Automatic shut-off during motor overload or power fluctuations

Many XQM models support vacuum jars or sealed milling chambers for grinding under vacuum or inert gas atmospheres (Argon, Nitrogen). This prevents oxidation, combustion, or unwanted chemical reactions in air-sensitive materials like metal powders, sulfides, and certain alloys.
