ATOMFAIR DPBM-6 DOUBLE PLANETARY BALL MILL 6L OVERLOAD PROTECTION

LABORATORY GRADE EQUIPMENT

Product Overview

The ATOMFAIR DPBM-6 Double 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-6 6L 4-jar double planetary design with variable frequency speed control and overload protection delivers revolution speeds of 70–560 r/min and rotation speeds of 140–1120 r/min. This listing is priced for the DPBM-6 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.

Key Features & Advantages

Dual Planetary Structure for High-Energy Grinding: The large planetary disk drives small grinding jars with larger revolution radius and rotation speed than ordinary planetary mills, multiplying centrifugal force for significantly enhanced collision, shearing and friction—capable of achieving nanometer-scale particle sizes.
Overload Protection for Safe Operation: Built-in overload protection system automatically shuts down the motor when excessive load is detected, preventing damage to the equipment and ensuring operator safety during high-energy grinding.
Heavy-Duty Industrial Construction: Professional industrial design with thickened steel plate welding, featuring high strength, impact resistance, deformation resistance and stable appearance. All machined parts undergo strict heat treatment and CNC 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 1500ml grinding jars (50–1000ml 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-6 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 1500ml jar capacities (50–1000ml 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. The overload protection system will activate during excessive load conditions—reduce feed quantity or adjust speed if tripping occurs. For detailed installation, operation, and maintenance instructions, consult the user manual prior to first use.
