electromagnetic microseismic sieve sander / standard sieve /
vibrating screen use and adjustment
1. Place the standard sieves in the order of the size of the mesh
apertures in the order of 6 mesh on the Zui, 260 mesh at the
bottom, and add a chassis) to the sieve holder of the sander, and
fasten the standard sieve with the cover 2. .
2. Turn on the power, adjust the timer knob 8 to the desired time
scale, and then adjust the amplitude knob 5 so that the amplitude
indicator 4 on the cover is at 3 mm. After adjusting, turn the
timer to zero.
Shock amplitude sign observation method:
When the sign 4 vibrates with the outer cover 2, due to the
persistence of the vision, the right angle side forms an
intersection with the chord side, and the scale value corresponding
to the intersection point is the double amplitude of the measured
object. As shown in the figure, the intersection point corresponds
to a scale of 2, that is, the amplitude is 2 mm.
3. Remove the outer cover 2 and the sieve cover, take the dried
sand sample (the residual weight of the 50 g sand sample after
washing the mud), pour it into the top 6 mesh sieve, and cover the
sieve cover. Secure the standard screen with a cover.
4. Turn the amplitude knob to the second gear, adjust the timer
knob 8 to 30, then adjust it back to the desired time scale, then
adjust the amplitude knob to the original position, and
automatically stop the vibration after the scheduled time arrives.
.
5. Open the outer cover 2, and pour the sand particles remaining in
each sieve into white wax paper, then pour into the glass dish, and
weigh them with the balance (accurate to 0.1 gram, gradual test to
0.01 gram) ). If sand is embedded in the crucible, do not hit the
standard sieve and gently brush it with a brush.
6. Weigh the remaining sand in each sieve and record it. The
percentage of each sand and sand sample (50 grams) was calculated
after zui.
7. After the work is finished, turn off the power.

Third, the principle
The tray of this machine is supported by S-type spring, and the
electromagnet is used for periodic suction to make the tray vibrate
for reciprocating spiral. The main circuit of the electromagnet
power supply is an AC switch circuit composed of four silicon
diodes connected into a bridge (for AC path) and a thyristor tube
to periodically energize the electromagnet. The thyristor trigger
signal triggers the thyristor after being divided by the power
frequency. The block diagram and circuit schematic are as follows:
