Electromagnetic sieve adopts electromagnetic drive to generate three-dimensional motion, and can sieve to 20 microns (635 mesh). This article will introduce electromagnetic sieve in detail for you.
Working principle of electromagnetic sieve
Electromagnetic sieve uses an electromagnetic vibrator as the vibration source, the vibration of the electromagnetic vibrator drives the low-position vibration of the sieve machine, and then transmits it to the stacked sieves fixed on the sieve machine through the base, and the vibrating motor (or reciprocating mechanism) installed at the lower part vibrates the sample Selective sieving, the sample vibrates on the sieve surface of the sieve, so that the sample particles smaller than the aperture of the sieve are sieved into the lower sieve until each layer of the sieve only has the same particle size samples that meet the specifications, reaching the sample distribution test. Purpose.
The use of electromagnetic sieve
The electromagnetic sieve uses the electromagnetic vibrator as the vibration source, adopts high-frequency up and down vibration, and the vibration frequency can reach 3000 times/minute, so the electromagnetic sieve has a finer screening capacity than the mechanical Sieve Shaker, and the screening can reach 20 microns (635 mesh ), if a negative pressure device is introduced into the electromagnetic sieve, the sample processing capacity can be reduced to 5 μm, which solves the problem of inaccurate dry sieving of ultrafine powder samples or difficult analysis.
The electromagnetic sieve is also suitable for the analysis and testing of relevant samples in laboratories in chemical, soil, food, pharmaceutical and other industries or in school laboratories. The light and exquisite design makes it small in size and light in weight, and can be placed directly on the laboratory operating table Use, of course, due to the particularity of the sample experiment and the delicate characteristics of the machine, please use it strictly in accordance with the operating procedures to obtain accurate experimental results and the longest service life of the machine.
