Introduction: 

 

WQS Laboratory Vibrator Screen

It is applied to particle analysis in the fields of pharmacy, metallurgy, foods, cosmetics and grain, and characterized by convenient operation, no rotary component, and electronic controlled amplitude and frequency. Its performance index is equal to that of the vibrator with sieve manufactured by German FRITSCH. In comparison with the traditional manual screen, it can greatly reduce labor intensity of operators and raise working efficiency. It is an essential laboratory screen for particle analysis.

Features: 

It is easy to operate for adopting advanced integrated circuit control.The main part of the vibrating screen is an electronic controlled electromagnet, on which there is a vibrating plate for mounting screens (8 at most, 50 mm high each). The electronic controlled electromagnet transfers to the vibrating plate a vibration of 3000 times / min (50 HZ) or 6000 times / min (100 HZ). On the vibrating plate install the screens,sieve-tray and screen head. The amplitude of the sieve-plate tower can be changed from 0 to 3 mm by means of the electronic controller. The screening time can be adjusted from 3 to 6 min by a timer There are three controllers: “Fine”, “Intermittent”, and “Continuation”.“Fine”: the vibrating screen vibrates in a low amplitude at a frequency of 6000 times / min (100 HZ). This operating mode is applied to the analysis of fine screening (especially for wet screening). “Intermittent”: the vibration screen vibrates as the required amplitude at a frequency of 3000 times / min (50 HZ). The vibration period of the sieve-plate tower can be set from 3 to 10 sec by a potentiometer. The stopping time is about 1.5 sec, preventing the resonance between the screen mesh and material and shortening the sieving time.“Continuation”: the working of vibrating screen is as above, but no Stopping. This operating mode is mainly applied to the materials that are easy to be sieved (the fine substances contained are not too many).In case of the sieving particles greater than 200 mesh, place screening-aid balls on the screens, each of which can use 10 agate balls of 10 mm in diameter each, or 5 rubber balls of 20 mm in diameter each, preventing from blocking the screen meshes.
