Benchtop Vertical Planetary ball Mill for Wet and Dry Grinding

Product Description:

The KS-GPM-13S Vertical Planetary Ball Mill is a high-efficiency, precision-engineered grinding system designed for advanced laboratory-scale sample preparation. Engineered with innovation and durability in mind, this benchtop device is tailored to meet the diverse grinding, mixing, and homogenizing requirements found in research institutions, materials labs, universities, and R&D centers.

This compact system is equipped with four grinding stations, each capable of accommodating stainless steel jars with a 4-cavity design. This configuration enables the simultaneous processing of up to 16 different samples per batch, which greatly enhances productivity and allows for comparative sample analysis under identical processing conditions. The jars are tightly secured using robust holding fixtures that can accommodate vessels with heights of up to 80 mm, ensuring reliable operation even at high speeds.

At the heart of the KS-GPM-13S is a powerful 550W motor operating on 208–240V AC, 50/60 Hz. It delivers exceptional centrifugal force and rotational energy, providing the user with efficient grinding performance and excellent particle size reduction. The main disk rotates at adjustable speeds up to 324 RPM, while each jar experiences a self-rotation up to 648 RPM, enabling a unique planetary motion. This 1:2 speed ratio ensures uniform grinding and fine control over particle size and homogeneity.

The system supports both wet and dry milling, with output granularity reaching sub-micron levels, depending on the material's hardness, feed size, and media type. Wet milling can achieve particles averaging below 1 μm, while dry milling typically yields results below 20 μm. For specialized applications, the unit is capable of producing powders as fine as 0.1 μm, depending on material properties and duration of processing.

One of the standout features of the KS-GPM-13S is its advanced touch-screen control panel. This intuitive interface allows users to configure up to 10 stored recipes, each with a maximum of 5 programmable speed segments and up to 10 cycles. Additional functions include direction control (clockwise/anticlockwise), real-time speed monitoring, and precise time adjustments—up to 99 hours 59 minutes per segment—making it suitable for both short bursts and extended grinding procedures.

To support material compatibility, the KS-GPM-13S is supplied with four sets of stainless-steel milling jars and balls. The included jars are ideal for metallic and hard inorganic materials, while optional jar materials (sold separately) such as tungsten carbide, zirconia, alumina, nylon, and agate enable contamination-free processing for sensitive applications like pharmaceuticals, semiconductors, and nanomaterials.

The vertical design minimizes the machine’s footprint while enhancing user accessibility and stability. Its noise level ranges between 55 to 70 dB, making it suitable for indoor laboratory environments without excessive disruption. The unit is also engineered for easy maintenance and long-term operation, with a sealed chamber that minimizes dust and contamination during milling.

Overall, the KS-GPM-13S combines compact form, advanced control, and powerful grinding performance into a versatile tool for modern material research. Whether you are conducting alloying, chemical mixing, powder dispersion, or nanoparticle synthesis, this vertical planetary ball mill delivers the flexibility and precision required for reproducible and reliable results.
