Ball Mixer Mill EQM-402

The EQM-402 Ball Mixer Mill is a compact desktop laboratory unit engineered for the efficient mixing and milling of small sample quantities through a combination of impact and friction forces. Designed for laboratories that require reliable and repeatable particle size reduction, the EQM-402 delivers powerful grinding performance in a small footprint, making it an ideal solution for research laboratories, quality control facilities, and analytical sample preparation environments.

At the core of the system is a horizontal oscillation movement that propels the grinding balls inside the milling jars with significant force. As the jars oscillate, the grinding balls repeatedly collide with the sample material and the inner walls of the jar. This motion generates a combination of impact energy and friction, which effectively breaks down the sample particles and reduces them to fine powder. The continuous oscillating action ensures thorough mixing and consistent particle size reduction, enabling laboratories to obtain accurate and reproducible analytical results.

The oscillation frequency is fully adjustable, allowing users to control the intensity of the milling process according to the characteristics of the sample. The EQM-402 can reach frequencies of up to 32 cycles per second, providing a wide range of milling power levels suitable for different materials and preparation requirements. Lower oscillation settings can be used for delicate samples that require gentle mixing, while higher frequencies provide the energy needed to efficiently grind harder or more resilient materials. This level of control ensures that laboratories can tailor the grinding process to achieve the desired final particle size while maintaining the integrity of the sample.

To improve efficiency and productivity, the EQM-402 Ball Mixer Mill is equipped with two 50 ml steel grinding jars that operate simultaneously. This dual-jar configuration allows users to process two samples at the same time or run parallel tests under identical conditions. The ability to work with multiple jars increases laboratory throughput and helps optimize workflows, particularly in environments where multiple samples must be prepared quickly and consistently. The grinding intensity can be further adjusted by selecting the number, size, and material of the grinding balls, providing additional flexibility in the milling process.

The EQM-402 is capable of handling a wide range of materials, including soft, semi-hard, hard, fragile, and brittle substances. This versatility makes it suitable for a broad spectrum of laboratory applications across multiple industries. The mill can operate using both dry grinding and wet grinding methods, allowing it to adapt to different analytical requirements and sample preparation protocols. Whether the goal is to homogenize a mixture, reduce particle size for chemical analysis, or prepare samples for further laboratory testing, the EQM-402 provides dependable and efficient performance.

One of the key advantages of the EQM-402 is its ability to reduce samples to analytical granulometry, achieving final particle sizes of less than 10 micrometers. This level of precision is essential for many laboratory analyses, where consistent particle size distribution directly affects the accuracy and reliability of results. By combining strong grinding power with precise control over milling parameters, the EQM-402 ensures that samples are processed to the exact specifications required for downstream analytical techniques.

In addition to its performance capabilities, the EQM-402 is designed with ease of use and operator convenience in mind. Its compact desktop design allows it to fit comfortably within laboratory workspaces without requiring large installation areas. The equipment is simple to operate, with intuitive controls that allow users to configure milling parameters quickly and efficiently. The system is also designed for safe, quiet, and stable operation, making it suitable for routine laboratory use.

The durable construction of the mill ensures long-term reliability, even under demanding laboratory conditions. High-quality components and robust materials help maintain consistent performance while minimizing maintenance requirements. This reliability, combined with its efficient grinding action and flexible operating parameters, makes the EQM-402 Ball Mixer Mill a practical and dependable solution for laboratories that require fast, precise, and repeatable sample preparation.

Overall, the EQM-402 Ball Mixer Mill provides an effective balance of performance, versatility, and compact design. Its ability to process a wide variety of materials, combined with adjustable milling parameters and dual-jar operation, makes it a valuable tool for laboratories seeking accurate and efficient particle size reduction. By delivering consistent results and simplified operation, the EQM-402 supports laboratories in achieving reliable analytical outcomes while improving overall workflow efficiency.
