SBM-15L Laboratory Stirred Ball Mill 60-380rpm Ultrafine Grinding ≤1μm

This powered mill requires selection of grinding cylinder and stirring components based on material compatibility to prevent contamination or accelerated wear. The grinding cylinder jacket enables precise temperature control, which is critical for heat-sensitive materials to avoid thermal degradation.

• Material Compatibility: Choose cylinder and stirrer materials (stainless steel, corundum, polyurethane, zirconia) that are chemically compatible with the processed material to avoid corrosion or wear.
• Vibration Management: Mount the mill on a stable, level surface and ensure the grinding media and load are balanced to maintain low vibration and noise during operation.
• Temperature Control: Utilize the integrated cooling jacket and adjust coolant flow to keep the grinding temperature within the safe range for both the mill components and the processed material.
• Speed Regulation: Set the rotational speed using the frequency converter within the 60–380 rpm range, adjusting for the desired particle size and grinding media type.
• Process Flexibility: Operate in batch or continuous mode as needed, and adjust residence time to control final fineness without exceeding the mill's loading capacity of 5.25 L.

Follow these steps to prepare the mill, select appropriate grinding media, and execute a controlled grinding run. Proper setup and monitoring ensure safe operation and consistent particle size reduction.

Required Equipment: JM-15L Lab Stirred Mill with automatic lifting and cooling jacket

1. Inspect and Prepare the Mill
   Inspect the grinding cylinder, stirring rod, and seals for damage or wear, and verify that the automatic lifting mechanism is functional.
2. Select Grinding Media
   Select grinding media of appropriate material and diameter (e.g., zirconia or corundum beads) based on the target final particle size and material hardness.
3. Load the Material and Media
   Load the material and grinding media into the cylinder, ensuring the total volume does not exceed the specified loading capacity of 5.25 L.
4. Set the Speed
   Set the rotational speed using the frequency converter within the 60–380 rpm range appropriate for the grinding media and desired shear intensity.
5. Start the Mill and Monitor
   Start the mill and monitor for abnormal vibration or noise, then adjust the cooling jacket flow to maintain a stable grinding temperature.
6. Adjust Process Parameters
   Adjust the residence time or speed incrementally to achieve the target particle size fineness, sampling periodically to verify progress.
7. Stop and Discharge
   Stop the mill, allow the cylinder to drain completely, and discharge the ground product using the tilting mechanism and automatic lifting feature.

The JM-15L lab stirred mill combines energy-efficient fine grinding with a jacketed cylinder for temperature control and automatic lifting for operator convenience, but its effective batch capacity of 5.25 L and reliance on residence time tuning for particle size control impose operational planning requirements.

Positive

• Energy-efficient fine grinding: High energy utilization and power density deliver outstanding energy-saving performance while producing fine particle sizes suitable for advanced materials processing.
• Versatile process and material adaptability: Jacketed cylinder enables precise temperature control, optional wear-resistant materials allow handling of diverse chemistries, and the mill supports both continuous and batch operation for flexible process development.

Trade-offs

• Effective batch volume limited to 5.25 L: The 15 L nominal cylinder volume accommodates a maximum material load of 5.25 L due to grinding media packing, restricting batch size for larger-scale laboratory trials.
• Particle size depends on residence time tuning: Achieving target fineness requires precise adjustment of material residence time within the mill, demanding process optimization for each feedstock and formulation.
