Specification
[1] zigzag sifter to separate solid compounds

[2] feed hopper with vibrating trough for feed of solid compound into sifter

[3] dosage of feed material by way of distance of hopper outlet from vibrating trough and frequency of vibrating trough

[4] separation of solid compound into coarse and fine material with air flow in 20-stage zigzag duct

[5] air flow generation by fan; adjustment by valve

[6] separation of fine material from air flow by gas cyclone with tangential inlet

[7] 3 tanks for feed material and coarse and fine materials

[8] recording of volumetric air flow rate and differential pressure through sifter and cyclone.
