Dual Planetary Ball Mill DPBM-1 1L 4-Jar Lab ATOMFAIR®

ATOMFAIR DPBM-1 DUAL PLANETARY BALL MILL 1L 4 JAR POSITIONS

LABORATORY GRADE EQUIPMENT

Product Overview

The ATOMFAIR DPBM-1 Dual Planetary Ball Mill is a laboratory-grade high-energy grinding equipment featuring a unique double planetary structure. The large planetary disk drives the small grinding jars in motion, with revolution radius and rotation speed larger than those of ordinary planetary ball mills of the same specification. The centrifugal force on the grinding balls is multiplied, significantly increasing collision, shearing and friction between the balls for improved grinding effect and efficiency. Some materials can be ground to nanometer scale. The DPBM-1 1L 4-jar dual planetary design delivers revolution speeds of 70–560 r/min and rotation speeds of 140–1120 r/min. This listing is priced for the DPBM-1 main unit only—grinding jars and grinding balls are ordered separately. The DPBM series spans from 0.4 L to 6 L models, covering research, pilot, and small-batch production across electronics, magnetics, pharmaceuticals, ceramics, geology, and advanced materials processing.

Precision Gear Drive System: Transmission gears are precision gears made of special materials, ensuring stable, safe and low-noise operation at high speed (60±5 dB).
Versatile Jar Compatibility: Compatible with 250ml grinding jars (50–100ml vacuum grinding jars available), supporting dry grinding, wet grinding, and vacuum grinding modes.
Flexible Programmable Operation: Variable frequency speed control with total set running time (1–9999 min) and forward-reverse alternating time (1–999 min) for customized grinding protocols.

APPLICATION SCOPE: Widely used in electronics, magnetics, pharmaceuticals, ceramics, geology, mineral resources, metallurgy, building materials, chemical industry, light industry, cosmetics, environmental protection and other industries. Specifically suitable for high-energy grinding of advanced materials, nanocomposites, battery materials, catalysts, pigments, ceramics, and pharmaceutical compounds requiring ultrafine particle size reduction.

PACKAGING: This listing is priced for the DPBM-1 main unit only. The standard configuration includes 1 pc grinding host machine. 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 250ml jar capacities (50–100ml vacuum grinding jars available). The DPBM series is available from 0.4 L through 6 L models. 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. Select jar and ball materials compatible with your target material to avoid cross-contamination. The dual planetary structure delivers significantly higher energy than standard planetary mills—adjust speed and grinding time accordingly to avoid over-grinding. For detailed installation, operation, and maintenance instructions, consult the user manual prior to first use.

The DPBM-1 must be operated on a stable, level surface with a 220V-50Hz electrical supply and proper grounding to prevent electrical hazards. The dual planetary design generates high centrifugal forces; users must select jar and ball materials compatible with the target material to avoid cross-contamination and ensure safe operation.

Electrical Supply: Operate only with a 220V-50Hz power supply and a motor power rating of 0.75 kW to avoid electrical damage.
Noise Level: The mill operates at a noise level of 60±5 dB; hearing protection is recommended during extended use.
Jar Compatibility: Only use compatible 250 ml grinding jars (or 50-100 ml vacuum jars) made of materials that are chemically inert to the sample to prevent contamination.
Over-grinding Risk: Adjust revolution speed (70-560 rpm) and rotation speed (140-1120 rpm) along with total run time to avoid over-grinding the sample.
User Manual Requirement: Review the user manual thoroughly before initial operation for installation, safety, and maintenance instructions.

FAQ

How does the dual planetary structure of the DPBM-1 improve grinding performance compared to conventional planetary ball mills?

The dual planetary design uses a larger planetary disk that drives smaller grinding jars with greater revolution radius and rotation speed, multiplying centrifugal force on the grinding balls. This significantly enhances collision, shearing, and friction, enabling some materials to be ground to nanometer scale. The DPBM-1 delivers revolution speeds of 70–560 r/min and rotation speeds of 140–1120 r/min.

What jar and ball material options are available for the DPBM-1 to prevent cross-contamination during milling?

The DPBM-1 is compatible with 250 ml grinding jars in materials including WC-Co, Al₂O₃, Agate, YSZ, SS, PU, Ceramic, and Nylon. Grinding balls are available in WC-Co, Al₂O₃, Agate, YSZ, SS, and IC-PU. The source advises selecting jar and ball materials compatible with your target material to avoid cross-contamination.

What are the electrical and space requirements for installing the DPBM-1 dual planetary ball mill?

The DPBM-1 requires a 220V-50Hz power supply with a 0.75 kW motor. It has overall dimensions of 1150×800×760 mm and a net weight of 250 kg. The unit operates at a noise level of 60±5 dB and should be placed on a stable surface capable of supporting its weight.

Assessment

The Atomfair DPBM-1 Dual Planetary Ball Mill delivers high-energy grinding via a dual planetary drive, achieving nanometer-scale particle sizes for advanced materials. Its programmable timing and variable frequency control offer flexibility, but jars and media must be sourced separately, and the increased energy requires careful parameter tuning to prevent over-grinding.

Positive

High-energy dual planetary grinding: The dual planetary structure multiplies centrifugal force via larger revolution radius and rotation speed, significantly enhancing collision, shearing, and friction to achieve nanometer-scale particle sizes.
Flexible programmable operation: Variable frequency speed control with total running time up to 9999 min and forward-reverse alternating time up to 999 min allows customized grinding protocols for diverse materials.

Trade-offs

Jars and media ordered separately: The main unit does not include grinding jars or balls, requiring separate procurement of compatible materials and increasing initial setup complexity.
Higher energy requires careful tuning: The dual planetary design delivers significantly higher energy than standard mills, so speed and grinding time must be adjusted to avoid over-grinding or sample damage.
