PBM-(8-12) Planetary Ball Mill 1.5KW 4-Jar ATOMFAIR®

ATOMFAIR PBM-(8-12) PLANETARY BALL MILL 4 JARS 1.5KW

LABORATORY GRADE EQUIPMENT

Product Overview

The ATOMFAIR PBM-(8-12) Planetary Ball Mill is a laboratory-grade grinding equipment designed for soil heavy metal analysis and advanced material research. Featuring PBM-(8-12) 1.5KW 4-jar configuration with a 162 mm jar holder inner diameter and Φ275 mm revolution diameter, this standard 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) 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. For accessory quotations, please contact inquiry@atomfair.com.

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

The PBM-(8-12) mill requires a 220 VAC electrical supply and accepts feed material with particle sizes up to 10 mm for soil or 3 mm for other materials. The grinding jar sealing pressure must be set via the graduated scale to prevent leakage and maintain sample integrity during operation.

Electrical Supply Requirements: Connect the mill to a 220 VAC power supply and ensure the circuit is rated for the 1.5 kW motor load.
Feed Particle Size Limits: Do not exceed 10 mm feed size for soil samples or 3 mm for other materials to avoid damage to the grinding jars.
Jar Sealing Adjustment: Adjust the sealing pressure of the grinding jars using the graduated scale to ensure proper containment during operation.
Material Compatibility for Contamination Control: For soil heavy metal analysis, use agate or Al₂O₃ jars with agate or YSZ grinding balls to minimize elemental interference.
Continuous Operation Duration: The mill can operate continuously at full load for up to 48 hours, but monitor motor temperature and vibration during extended runs.

FAQ

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

For soil heavy metal analysis, agate (natural SiO₂) or high-purity Al₂O₃ (95%) grinding jars combined with agate or yttria-stabilized zirconia (YSZ) grinding balls are recommended to minimize elemental interference. These materials are specifically cited in the product description for minimal contamination during ultrafine grinding.

Does the PBM-(8-12) support wet grinding and vacuum grinding in addition to dry grinding?

Yes, the PBM-(8-12) supports dry grinding, wet grinding, and vacuum grinding modes. The grinding jars can be sealed with adjustable pressure via a graduated scale, enabling vacuum operation. Two or four jars can operate simultaneously.

What is the maximum continuous operation time and how is the sealing pressure controlled?

The mill can operate continuously at full load for up to 48 hours. The grinding jar sealing pressure is adjustable via a graduated scale, allowing precise control to maintain sample integrity and prevent cross-contamination during extended runs.

Assessment

The ATOMFAIR PBM-(8-12) Planetary Ball Mill is a laboratory-grade grinding system designed for soil heavy metal analysis, featuring ultrafine grinding down to 0.1 μm and an integrated electric screener for particle size classification, but requires separate purchase of consumables and has substantial weight (168 kg) and power requirements.

Positive

Ultrafine grinding down to 0.1 μm: From feed size ≤10 mm, the mill achieves discharge particle size as fine as 0.1 μm using high-energy planetary motion, suitable for demanding soil analysis.
Integrated electric screener for particle classification: The included electric screener holds up to seven layers of sieves (20–200 mesh) and provides digital display, enabling integrated sample preparation and size analysis.

Trade-offs

Grinding jars and balls ordered separately: The main unit price excludes grinding jars and balls, which must be purchased separately, adding to initial setup cost and requiring careful material selection.
Heavy weight and power requirements: The machine weighs 168 kg and requires 220V AC, necessitating robust lab infrastructure and potentially limiting portability.
