Slayer Exciter Circuit with a Tesla Coil

The greatness of the Slayer Exciter is that it makes the circuit oscillate exactly at that frequency. But I tried to use a function generator instead to excite the circuit which is another option. I found it quite tough to tune the frequency to the exact resonance of the coil, something that the Slayer does automatically. Get price

Coal Dewatering Screen

When working, the two unrelated actuators are driven by belt couplings to run synchronously and in reverse. The centrifugal forces produced by the two groups of eccentric blocks are superimposed along the vibration direction and counteracted by reverse centrifugation, thus forming a single excited vibration along the vibration direction, which makes the screen box move back and forth in a Get price
