Working Principle

A vibratory cup mill pulverizes materials through high-frequency three-dimensional vibration.
Inside the grinding bowl (jar), the ring and puck move in combined circular and vertical motions, generating pressure, impact and friction that rapidly reduce materials to analytical fineness.

Features & Advantages

✅ Rapid grinding to analytical fineness (≤20 µm)
✅ Uniform and repeatable results
✅ Multiple material options: WC / ZrO₂ / Stainless-Steel + Carbide
✅ Dry and wet grinding modes
✅ Precision-balanced and easy to clean
✅ Customizable to any mill geometry

SPEED

Rapid grinding to analytical fineness (≤20 µm)

SPEED

Feed size: ≤ 10–12 mm
Final fineness: ≤ 10–20 µm
Grinding time: 30–180 s
Efficient three-dimensional vibration ensures fast pulverizing of hard, brittle, and fibrous materials to analytical-grade fineness within minutes.

PRECISION

Consistent, reproducible grinding performance

PRECISION

Each bowl set is dynamically balanced and geometrically optimized to maintain uniform pressure and motion during operation, ensuring highly consistent particle size distribution and reproducibility across batches.

DURABILITY

Engineered for maximum wear resistance and impact strength

DURABILITY

Made from high-toughness tungsten carbide (MC15 grade) and consolidated by vacuum sintering with HIP densification, the grinding components feature excellent hardness (≈89.5 HRA) and fracture toughness (KIC > 11 MPa·m¹/²), ensuring long service life under high-impact vibration.

Material Options

Material	Characteristics	Typical Use
Solid Tungsten Carbide (WC)	Ultra-hard and wear-resistant	Ores, metals, ceramics, ultra hard material
Stainless Steel Embedded Carbide	Balanced strength and hardness	Cement, slag, minerals
Zirconia (ZrO₂)	Chemically inert, non-metallic	Oxides, ceramics, soil, purity testing

Solid Carbide

Zirconia

SS+Carbide

Technical Insight

Design for Durability and Reliability

From our collaboration with global laboratories, we’ve identified common wear challenges — edge chipping, ring fracture, and stress concentration — and engineered solutions to prevent them:

Optimized edge radius (R2–R3): minimizes stress concentration and edge chipping.
High-toughness MC15 carbide: hardness (HRA 86.5) and Bend strength:3200 Mpa.
Bend strength:3200 Mpa
Geometry-matched ring, puck, and bowl sets: prevent uneven stress distribution.

Non-Magnetic Grade Option for Ferroalloys and High-Fe Materials

For materials with very high iron content (Fe > 75%)—such as ferroalloys, pig iron, sponge iron, or metallurgical feedstock—conventional carbide grades may create partial adhesion between the sample and the inner surface of the grinding bowl due to magnetic interaction.

To address this issue, Miller offers an optional non-magnetic carbide grade, specifically engineered to:
