High Purity Alumina Planetary Milling Jar for Laboratory Grinding

ZYLAB High Purity Alumina Planetary Milling Jar

Introduction:

The ZYLAB Alumina Planetary Milling Jar is made of high-purity alumina (>95%) and sintered at 1850°C for outstanding hardness, wear resistance, and chemical stability.

The jar features a one-piece structure with a large-radius inner transition design, ensuring no dead corners, no leakage, and easy cleaning. With thick walls and a flat sealing gasket, it provides a tight seal while preventing material agglomeration. The body is robust, beautifully designed, and ideal for long-term, high-intensity milling. It delivers excellent grinding efficiency and produces ultra-fine, uniformly distributed particles in a short time.

Key Features:

• High-Purity Alumina (>95%) – Offers excellent hardness, wear resistance, and chemical inertness.

• Sintered at 1850°C – Ensures high mechanical strength and long service life.

• One-Piece Jar Body – Seamless construction for enhanced durability and easy cleaning.

• Flat Sealing Gasket – Provides tight sealing and prevents material agglomeration.

• Large-Radius Inner Bottom (R Angle) – Eliminates sedimentation and dead corners.

• Thick Wall Design – Improves stability and impact resistance during high-speed rotation.

• Ergonomic Design – Smooth, elegant structure with easy opening and closing.

• Efficient Milling Performance – Achieves fine and uniform particle size distribution quickly.
