Air-jet sieve for difficult materials

The LPS200K precision air-jet sieve from Christison Particle Technologies is designed for the determination of size distribution of fine particles down to 20 microns.

"Air is conducted through the sieve by a rotating slot, with a variable speed of 0–45 rev/min, while the air jet deagglomerates the sample and keeps the sieve mesh from blinding. On top of the sieve mesh the air jets are redirected back through the sieve and the fines are transported into the collection system by the airflow. After the sieving cycle the remaining sample is weighed and the percentage retained/passing can be calculated."

"The controlling microprocessor also records data. Sieving time and rotor speed are indicated, together with negative pressure and the comparable gas stream volume. Operations are controlled using a five-button menu-guided control pad. The unit uses standard 200mm diameter sieves and features an electrical connection for a vacuum cleaner and a connector flange for a suction tube."
