F4 Series Laboratory Sand Mill

​

The F4 Series Laboratory Sand Mill is an advanced and upgraded version of the W Series laboratory sand mill. It not only retains all the proven features and reliable performance of the W Series but also incorporates several innovative improvements that provide greater flexibility, efficiency, and convenience for laboratory grinding and dispersion applications. ​One of the key advantages of the F4 Series is its versatile grinding system. Each machine is supplied with two grinding chambers of different capacities—0.5 L and 0.1 L—along with corresponding stirring shafts and rotors designed specifically for each chamber size. This configuration allows users to easily adapt the equipment to different sample volumes and experimental requirements without the need for multiple machines.

​To further enhance flexibility, the F4 Series features specially designed conversion plugs that enable the grinding chamber volumes to be adjusted. The 0.5 L chamber can be converted to 0.3 L, while the 0.1 L chamber can be converted to 0.05 L. As a result, a single machine can accommodate four different working volumes: 0.05 L, 0.1 L, 0.3 L, and 0.5 L, making it ideal for research laboratories, product development, and pilot-scale testing where varying batch sizes are often required. ​The machine is also equipped with two maximum speed settings optimized for different chamber sizes. For the smaller 0.05 L and 0.1 L chambers, the maximum rotational speed reaches 4425 rpm, ensuring efficient grinding and excellent dispersion performance for small-volume samples. For the larger 0.3 L and 0.5 L chambers, the maximum speed is 3300 rpm, providing stable operation and consistent processing results.

​Another significant benefit of the F4 Series is its shared host platform design. All four volume configurations utilize the same machine base, allowing users to switch between chamber sizes as needed while minimizing equipment investment and laboratory space requirements. Although only one chamber specification can be operated at a time, this modular design offers exceptional versatility and cost-effectiveness. ​With its multiple chamber options, adjustable working volumes, optimized speed control, and compact modular structure, the F4 Series Laboratory Sand Mill is an ideal solution for laboratories seeking precise, efficient, and flexible grinding and dispersion capabilities across a wide range of research and development applications.
