EQR-200 Vibratory Disc Mill

The EQR-200 is a vibratory disc mill designed for the rapid reduction of solid samples to analytical granulometry in laboratory environments. Built for high-performance sample preparation, it delivers fast, consistent grinding results that make it a practical and reliable instrument for laboratories requiring precise particle size reduction prior to chemical analysis, material characterisation, or X-ray fluorescence (XRF) testing.

The mill operates through 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 breaks down particles efficiently and produces a fine, homogeneous powder suitable for accurate analytical measurements. Because the grinding action takes place within a sealed milling jar, the sample is processed quickly while minimising contamination and maintaining consistency throughout.

One of the most significant advantages of the EQR-200 is its grinding speed. The system is capable of reducing samples to particle sizes below 45 micrometres in under 60 seconds, substantially improving laboratory productivity and reducing the time required for sample preparation. This rapid processing capability is particularly valuable in laboratories that handle large sample volumes or operate under tight turnaround requirements. The grinding process delivers particle size dispersion of less than 1% between consecutive grindings of the same material, providing the level of repeatability that accurate analytical work depends on.

The mill handles a wide range of materials including hard, semi-hard, brittle, and fibrous substances, making it suitable for use across a broad range of industrial and scientific environments. Milling tools are manufactured from hardened steel or tungsten carbide to ensure durability and minimise wear during intensive grinding operations, providing long service life even with demanding sample types. The robust mechanical structure and powerful motor work together to maintain stable, uniform particle size reduction across extended operating cycles.

Operation is straightforward. A digital control screen allows users to select from five preset grinding programs or configure their own parameters to suit the specific requirements of each sample. This flexibility means laboratory staff can achieve reliable and repeatable results without complex setup procedures, reducing preparation time and the potential for operator error. An automatic door locking system prevents the unit from operating while open, ensuring safe operation during high-speed grinding. Despite its powerful motor and rapid milling performance, the EQR-200 operates at low noise levels, making it well suited to laboratory environments where noise control is a consideration.

The EQR-200 is designed for analytical laboratories, sample preparation laboratories, and production environments where fast, accurate, and repeatable particle size reduction is an ongoing requirement. Its combination of speed, precision, durability, and ease of operation makes it a dependable long-term instrument for laboratories performing chemical analysis, quality control testing, and material characterisation at scale.

• Production process monitoring

The EQR-200 features an intuitive digital control system designed to give operators precise and consistent control over the milling process. Users can select from five preset grinding programs for routine sample types or configure their own parameters, with grinding speed adjustable between 750 and 1,500 rpm and grinding time settable from zero up to 99 minutes and 59 seconds. Customised milling parameters can be stored within the system, allowing laboratories to build a library of optimised settings for different materials and preparation requirements and recall them quickly without reconfiguring the system each time.

This level of control supports consistent and repeatable grinding results across every sample batch, reducing the reliance on operator judgment and minimising variability between runs. For laboratories processing a variety of sample types on a daily basis, the ability to define, store, and switch between milling programs efficiently is a practical advantage that contributes to both workflow speed and the reliability of downstream analytical results.
