Precision Three Roll Mill SIE‑BM500


Dual Grinding with Impact & Shear Force · Flexible 1/2/4 Jar Configuration · Continuous Low-loss High-efficiency Pulverization

Output fineness below 0.1μm + continuously adjustable main disc speed 100–650rpm + dry & wet grinding available

SIENOX SIE-BM500 high-energy planetary ball mill delivers superior performance. The turntable accepts bases for 1, 2 or 4 grinding jars. Compact and easy to operate, it reaches up to 650 rpm to continuously and efficiently grind hard, soft, brittle, dry and wet materials with minimal loss. Beyond regular powder milling, SIE-BM500 meets energy and technical requirements for mechanical alloying and gelatinous material grinding.

Grinding jars in 80mL, 250mL and 500mL sizes cover R&D trials through small-batch production. Jars are mounted on the main revolving disc and spin in reverse at high speed. Grinding balls inside achieve ultra-fine pulverization via high-speed friction and impact. It features a programmable touch LCD for timing, forward/reverse cycling, interval operation and data storage. Dual forced cooling fans ensure stable long-running performance. Ideal for lithium battery material pilot tests, mechanical alloying and small-batch ceramic powder production.

Why Precision Grinding Is Required

Coarse particles and poor dispersion in slurry directly degrade end‑product quality

Lithium Battery Material Pilot Test

When cathode and anode materials such as NCM, LFP and graphite move from lab-scale tests to pilot trials, larger batch grinding validation is required. Equipped with 500mL grinding jars, SIE-BM500 meets scale-up demands. Zirconia or agate jars prevent metal ion contamination and ensure consistent data between lab and pilot batches.

Mechanical Alloying

Metal powder alloying requires prolonged high-energy ball milling. Ordinary mills deliver insufficient energy and take long processing time. SIE-BM500 reaches up to 650rpm with centrifugal acceleration of 22–29g, supplying enough energy for metal powder alloying and nanocrystallite fabrication.

Small-batch Trial of Ceramic Powder

MLCC dielectric powder and structural ceramic powder require 500mL-scale grinding for formulation verification to evaluate forming and sintering performance. Multi-material grinding jars are available to avoid cross-contamination between ceramic formulations. Small trial batches can verify final product performance.

✨ Limitations of conventional sample pretreatment: High-speed dispersers only mix and disperse instead of performing real grinding; sand mills suit mass production rather than frequent grade switching for small batches; small ball mills have limited capacity and fail to meet R&D scale-up requirements. SIE-BM500 balances grinding fineness and single-batch throughput.

Why Choose SIE‑BM500

Solves Core Pain Points of Laboratory Small‑sample Grinding

Dual Ultra-fine Grinding with Impact & Shear Force

Material pulverization and grinding are mainly realized by high-speed friction and collision among grinding balls. The maximum speed of the main disc reaches 650rpm. As the main disc revolves, the grinding jars loaded with samples and balls spin in the opposite direction at high speed around their own axes. Balls move rapidly inside jars and further crush samples by hitting the jar wall and rubbing against each other. It usually takes no more than 5 minutes to reach analytical-grade fineness, with output particle size below 0.1μm, meeting fineness requirements from R&D to small-batch production.

Flexible 1/2/4 Jar Configuration for Variable Batches

One turntable supports 1, 2 or 4 jars. Grinding jars are available in 80mL, 250mL and 500mL sizes. Single jar for small R&D batches, dual or four jars for parallel comparison tests, full four-jar setup for small-scale production. Horizontal guide rail counterweight together with arched counterweight plate requires no re-balancing after jar quantity change, enabling fast material switching.

Suitable for Mechanical Alloying & Gel Material Grinding

SIE-BM500 performs not only routine ultra-fine powder grinding, but also delivers sufficient energy input for mechanical alloying and gel material grinding. Grinding jar materials include stainless steel, vacuum stainless steel, agate, ceramic, zirconia, nylon, PTFE, tungsten carbide and silicon nitride, suitable for metal powder alloying, high-purity materials, corrosive samples and other working conditions.

✨ If your R&D needs scaling up from lab trials to pilot tests or high-energy ball milling processes such as mechanical alloying, SIE-BM500 is your ideal choice.

Working Principle

Based on planetary motion principle

SIENOX SIE-BM500 operates based on the planetary motion principle. Grinding jars are mounted on the main disc (sun wheel). While the main disc revolves around the central axis, the grinding jars spin rapidly on their own axes in the opposite direction. The transmission ratio is 1:1.82 for single jar and 1:2.19 for four jars.

 

Under this compound motion, the grinding media (balls) inside the jar are subjected to two alternating forces:

Impact Force: The balls are thrown during high-speed movement and deliver strong impact on samples to break coarse particles.

Friction & Shear Force: High-frequency friction and shear occur between balls and between balls and jar walls to grind and disperse fine particles.


When the centrifugal acceleration from revolution exceeds the critical value, balls are pressed against the jar wall and rotate together with the vessel without effective grinding. Therefore, proper speed setting and transmission ratio design are critical to grinding efficiency. With optimized transmission ratios, SIENOX ensures proper centrifugal acceleration under different jar configurations for high-efficiency milling.


Typical Grinding Parameters for Reference:

Sample Loading: ≤ 2/3 of jar volume (including grinding media and sample)

Media Filling Ratio: Usually 1/3 to 1/2 of jar volume

Typical Milling Time: 5–60 minutes (depends on material hardness and target fineness)

Final Output Fineness: Down to <0.1μm (depends on sample material, milling parameters and media selection)
