The AS 450 control sieve analysis is used in laboratories for research and development, quality control of raw materials, intermediate products and finished products as well as production monitoring. The controlled solenoid drive enables optimum adaptation to any material to be screened. Even with short sieving times, the camera convinces by high precision separation.

The AS 450 control sieve analysis is the first sieve to oscillatory movements in three dimensions for RETSCH sieves of 400 mm and 450 mm in diameter. It is suitable for sifting dry and wet. The electromagnetic drive powered by the patented CET technology allows an amplitude up to 2.2 mm, whatever the load, up to 25 kg of sieved material. Thus, the AS 450 significantly outperforms all sifters for sale on the market with conventional electromagnetic drives or unbalanced vibration motors.

Application examples
Coal, clinker, coke, construction materials, filler, minerals, ores, plastics, chemicals, sand, soils, ...

Operating principle
The sieve shaker AS 450 control works with an electromagnetic drive with RETSCH holds the patent (EP 0642844). This system provides a three-dimensional projection of motion which distributes the sample uniformly over the entire surface of the sieve. It is efficient, highly effective and significantly reduces time to screening. This technology is virtually indestructible and requires no maintenance.
