High Frequency Electromagnetic Vibrating Screen

Superior Fine Screening Efficiency, Down to 0.074 mm

The high-frequency electromagnetic excitation — operating at 20–60 Hz compared to 12–17 Hz for conventional circular vibrating screens — dramatically increases the number of particle-aperture contact events per unit time, giving fine particles far more opportunities to pass through the screen apertures on each pass. This delivers screening efficiencies of 90–97% for particles in the 0.074–3 mm range, significantly outperforming conventional screens that typically achieve 50–70% efficiency at these fine cut sizes.

Electromagnetic Anti-Blinding Technology

The rapid high-frequency micro-vibration of the screen panel surface continuously agitates near-size particles that would otherwise lodge in and block the screen apertures, effectively preventing blinding without the need for ball trays, rubber bounce balls, or ultrasonic cleaning systems. This makes the High Frequency Electromagnetic Vibrating Screen the preferred solution for screening wet, sticky, or near-size materials that chronically blind conventional wire mesh or polyurethane panels at coarser vibration frequencies.

Adjustable Frequency & Amplitude for Process Flexibility

The electromagnetic excitation frequency and vibration amplitude are independently adjustable via the electronic controller panel without stopping the machine or changing any mechanical components. This allows operators to optimize screening performance in real time as feed material characteristics change — increasing frequency to improve efficiency for finer cut sizes, or reducing frequency to extend screen panel life for coarser, more abrasive feeds — providing exceptional process flexibility from a single machine.

Low Energy Consumption

The electromagnetic drive system consumes significantly less energy than equivalent motor-eccentric or motor-unbalance drive systems because it drives only the lightweight screen panels and frame rather than a heavy eccentric shaft and flywheel assembly. Typical power consumption is 0.5–7.5 kW per unit depending on screen size, delivering the lowest energy cost per tonne of screened material in the fine classification size range compared to any alternative screening technology.

Modular Screen Panel System for Rapid Maintenance

Screen panels are mounted in individually removable, quick-release tensioning frames that allow a single worn or damaged panel to be replaced in minutes without tools, without removing adjacent panels, and without stopping adjacent equipment. The modular panel system accommodates mixed aperture sizes on the same deck — coarser apertures at the feed end and finer apertures at the discharge end — to optimize throughput and efficiency simultaneously across the full deck length.

Compact Footprint, Easy Retrofit

The compact, lightweight design — significantly smaller and lighter than conventional vibrating screens of equivalent screening area — allows the High Frequency Electromagnetic Vibrating Screen to be installed in existing plant structures with limited headroom and floor space, or directly above existing conveyors and sumps without structural reinforcement. This makes it the ideal solution for upgrading existing screening circuits to achieve finer cut sizes or higher screening efficiency without plant expansion or significant civil work.
