ATOMFAIR PBM-(8-12)A SEMI-CIRCULAR PLANETARY BALL MILL 1.5KW

LABORATORY GRADE EQUIPMENT

Product Overview
The ATOMFAIR PBM-(8-12)A Semi-Circular Planetary Ball Mill is a laboratory-grade grinding equipment designed for soil heavy metal analysis and advanced material research. Featuring PBM-(8-12)A 1.5KW 4-jar semi-circular configuration with a 162 mm jar holder inner diameter and Φ275 mm revolution diameter, this semi-circular type mill delivers jar rotation speeds up to 580 r/min. The grinding jars revolve around the turntable axis while rotating reversely around their own axes, generating high-speed collision and friction forces that pulverize samples from ≤10 mm feed size down to ultrafine 0.1 μm discharge particles. The sealing pressure of the grinding jars is adjustable via a graduated scale. Purpose-built for soil heavy metal analysis and environmental testing, this machine supports dry grinding, wet grinding, and vacuum grinding modes. Two or four grinding jars can operate simultaneously. With stepless speed regulation, automatic timing for forward/reverse rotation, and up to 48 hours continuous full-load operation, the PBM-(8-12)A ensures reproducible sample preparation for research and quality control laboratories. Grinding jars and grinding balls are ordered separately. The PBM series spans from 0.2 L mini models to 200 L production units.

Working Principle
This machine is used for heavy metal analysis in soil, equipped with 4 grinding jars. The sealing pressure of the grinding jars is set by a graduated scale. The jars revolve around the turntable axis and rotate reversely around their own axes at the same time. Samples in the jars collide and rub against each other during high-speed movement, so as to crush, grind, mix and disperse samples. It can be used for dry grinding, wet grinding and vacuum grinding. Two or four grinding jars can operate at the same time.

Key Features & Advantages
  • High-Energy Planetary Motion for Ultrafine Grinding: Jars revolve around turntable axis while rotating reversely around own axes at up to 580 r/min, delivering intense collision and friction forces for ultrafine grinding down to 0.1 μm from ≤10 mm feed size.
  • Semi-Circular Design for Enhanced Stability: The semi-circular configuration provides improved structural rigidity and operational stability during high-speed grinding, reducing vibration and ensuring consistent particle size distribution.
  • Versatile Jar Capacity Options (2L or 3L): The PBM-(8-12)A accommodates either 2L or 3L grinding jars, providing flexible batch processing capacity for diverse research and pilot production requirements.
  • Complete Soil Analysis System with Integrated Screener: Includes electric screener with up to 7 layers of sieves (20–200 mesh, 20 μm) and digital display, providing a comprehensive soil grinding and screening solution from sample preparation to particle size analysis.

APPLICATION SCOPE: Soil heavy metal analysis, environmental testing, geological sample preparation, powder metallurgy, ceramic material research, mining analysis, pharmaceutical R&D, and quality control laboratories requiring reproducible ultrafine grinding and particle size classification.
PACKAGING: This listing is priced for the PBM-(8-12)A main unit only. The standard configuration includes 1 pc grinding host machine, 1 pc electric screener, and 1 complete set of round frame sieves (20–200 mesh + base). Grinding jars (WC-Co · Al₂O₃ · Agate · YSZ · SS · PU · Ceramic · Nylon) and grinding balls (WC-Co · Al₂O₃ · Agate · YSZ · SS · IC-PU) are ordered separately. Compatible with either 2L or 3L jar capacities. The PBM series is available from 0.2 L miniature models through 200 L production units. Installation guidance and operational training support are provided upon request.
IMPORTANT NOTICE: The listed price is for the main unit; grinding jars and balls must be ordered separately. This model supports both 2L and 3L grinding jars—select the appropriate capacity based on your batch size requirements. For soil heavy metal analysis, agate or Al₂O₃ jars with agate or YSZ balls are recommended for minimal elemental interference. For detailed installation, operation, and maintenance instructions, consult the user manual prior to first use.

The PBM-(8-12)A planetary ball mill requires separate purchase of compatible grinding jars and media. Consult the user manual for safe operation and maintenance before first use.

  • Compatible Jar and Media Requirement: The grinding jars and grinding balls are ordered separately and must be compatible with the mill.
  • User Manual Reference: Consult the user manual prior to first use for detailed installation, operation, and maintenance instructions.

The mill uses planetary motion to grind samples from feed size ≤10 mm to ultrafine 0.1 μm. The sealing pressure is adjustable via a graduated scale, and the mill supports dry, wet, and vacuum grinding modes.

Required Equipment: Planetary Ball Mill Main Unit, Grinding Jars, Grinding Balls

  1. Select and Obtain Compatible Grinding Jars and Media
    Select and obtain compatible grinding jars and grinding balls, ensuring the balls occupy approximately 40% of the jar volume.
  2. Load Sample and Media into Jars
    Load the sample and grinding media into the grinding jars.
  3. Seal Jars and Adjust Sealing Pressure
    Seal the jars and adjust the sealing pressure using the graduated scale.
  4. Place Jars into Mill Holders
    Place the jars into the mill holders, with two or four jars operating simultaneously.
  5. Set Speed and Time and Start Mill
    Set the rotation speed and time using the stepless speed regulation and automatic timing, then start the mill.

What feed size and final particle size can the PBM-(8-12)A planetary ball mill achieve, and what grinding modes does it support?

The PBM-(8-12)A can process samples from ≤10 mm feed size down to ultrafine 0.1 μm discharge particles. It supports dry grinding, wet grinding, and vacuum grinding modes, with two or four grinding jars operating simultaneously.

Which jar and ball materials are recommended for soil heavy metal analysis to minimize elemental interference?

For soil heavy metal analysis, agate or Al₂O₃ jars with agate or YSZ balls are recommended to minimize elemental interference. The grinding jars and balls are ordered separately, with available jar materials including WC-Co, Al₂O₃, Agate, YSZ, SS, PU, Ceramic, and Nylon, and ball materials including WC-Co, Al₂O₃, Agate, YSZ, SS, and IC-PU.

How is the sealing pressure of the grinding jars controlled, and what is the maximum continuous operation time?

The sealing pressure of the grinding jars is adjustable via a graduated scale on the semi-circular configuration. The mill supports up to 48 hours of continuous full-load operation with stepless speed regulation and automatic timing for forward/reverse rotation.

The Atomfair PBM-(8-12)A semi-circular planetary ball mill delivers ultrafine grinding down to 0.1 μm with enhanced stability via its semi-circular design, but requires separate procurement of grinding jars and careful material selection to avoid elemental interference in soil heavy metal analysis.

Positive

  • Ultrafine grinding to 0.1 μm: High-energy planetary motion with jar rotation up to 580 r/min reduces feed material from ≤10 mm to 0.1 μm, enabling reproducible sample preparation for advanced material research and soil heavy metal analysis.
  • Semi-circular structural stability: The semi-circular configuration improves structural rigidity and operational stability during high-speed grinding, reducing vibration and ensuring consistent particle size distribution.

Trade-offs

  • Grinding jars and balls sold separately: Jars and balls must be ordered separately, requiring additional procurement steps and compatibility consideration for the 2L or 3L jar capacity options.
  • Material selection for contamination control: For soil heavy metal analysis, agate or Al₂O₃ jars with agate or YSZ balls are recommended to minimize elemental interference, placing a material selection burden on the user.
