The LMSM is maintenance free due to the electromagnetic vibrating unit. The vibratory action produced by the power unit moves the sample over the sieve in a unique way producing faster more efficient sieving, while the rapid vertical movements also help to keep the apertures clear from blinding.
The vibration is controlled by a microprocessor. The digital controller is used to set both the process time and the amplitude setting while a further control enables the vibration to run continuously or intermittently. Intermittent vibration improves performance and helps to clear apertures that may have become blocked. The controller will also set the duration of both the on and off times of the vibration. All sieving parameters are digitally pre-selected and can be stored and recalled.
