EQR-200 Vibratory Disc Mill

The EQR-200 Vibratory Disc Mill is a powerful laboratory grinding unit designed to rapidly reduce solid samples to analytical granulometry in seconds. Built for high-performance sample preparation, the EQR-200 delivers extremely fast and consistent grinding results, making it an essential tool for laboratories that require reliable particle size reduction prior to chemical analysis or X-ray fluorescence (XRF) testing.

This vibratory disc mill operates using a combination of pressure, friction, and shear forces generated by high-frequency vibration. During operation, the grinding set vibrates intensely, causing the grinding elements to exert powerful mechanical forces on the sample material. This process efficiently breaks down particles and produces a fine, homogeneous powder suitable for accurate analytical measurements. Because the grinding action occurs within a sealed milling jar, the sample is processed quickly while maintaining consistency and minimizing contamination.

One of the key advantages of the EQR-200 is its exceptional grinding speed. The system is capable of producing particle sizes below 45 µm in less than 60 seconds, significantly improving laboratory productivity and reducing sample preparation time. This rapid processing capability makes the EQR-200 particularly valuable in laboratories that handle large sample volumes or require quick turnaround times for analysis.

The mill is designed to handle a wide range of materials, including hard, semi-hard, brittle, and fibrous substances. Its versatility allows it to be used in various industrial and scientific environments where accurate sample preparation is critical. To ensure durability and minimize wear during intensive grinding operations, the milling tools are manufactured from hardened steel or tungsten carbide. These high-quality materials provide long service life while maintaining reliable grinding performance even with demanding sample types.

The EQR-200 is engineered with a robust mechanical structure and a powerful motor, allowing it to operate smoothly and efficiently while delivering uniform particle size reduction. The optimized design ensures that the grinding process remains stable and repeatable, resulting in particle size dispersion of less than 1% P/P between consecutive grindings of the same material. This high level of repeatability is essential for laboratories that rely on consistent sample preparation to obtain accurate analytical results.

Ease of use is another key feature of the EQR-200 Vibratory Disc Mill. The system is equipped with a digital control screen that allows users to operate the mill quickly and intuitively. Operators can choose from five preset grinding programs or configure their own grinding parameters depending on the specific requirements of the sample. This simplified operation ensures that laboratory staff can achieve reliable and repeatable grinding results without complex setup procedures.

The equipment is also designed with safety and operator comfort in mind. The EQR-200 includes an automatic door locking system that prevents the unit from operating while open, ensuring safe operation during high-speed grinding processes. Despite its powerful motor and rapid milling performance, the system operates with low noise levels, making it suitable for laboratory environments where noise control is important.

Thanks to its durable construction, efficient grinding mechanism, and minimal maintenance requirements, the EQR-200 provides long-term reliability even in demanding industrial or laboratory settings. The mill is specifically designed for use in analytical laboratories, sample preparation laboratories, and production environments where fast and accurate particle size reduction is essential.

Overall, the EQR-200 Vibratory Disc Mill combines speed, precision, durability, and ease of operation in a single high-performance laboratory instrument. Its ability to quickly produce fine, homogeneous powders with excellent repeatability makes it an indispensable tool for laboratories performing chemical analysis, material characterization, and quality control testing.
