Based on analysis of problems existed in application of inertial vibrosieve,the new type variable frequency hydraulic straight-vibrating sieve is introduced.
The bugaboos in larger versions of this optimistic vision are highly variable flows of material, and decentralized, dilute concentrations of reclaimable stuff.
Besides, there is also some alternatives, such as an inductance conversion using differential transformer and space curve deformeter, and variable resistance pressure transmitter.
