Some of the 18inch cutter suction dredgers are driven by four stroke internal combustion engines with a small amount of extra power for high speed operation. However, it is not allowed to operate continuously at high speed for a long time, and it is determined according to the elevation and working depth under water.
The speed of the cutter suction dredger depends on the need for sufficient suction power to feed the material section into the nozzle. Your recovery system should be adjusted to suit the needs of better handling capacity.
When you are gold mining in the ore belt and suddenly find a lot of gold, give the sand pump a few minutes of clear water, remove the light materials from the strip, and then draw the gold. Most experienced gold miners are entering the gold rich ore belt to suck gold a little faster than the normal rate of other physical sciences.
If your sand pump keeps recovering gold at normal speed, it may not be necessary. However, when a large amount of gold is inhaled into the nozzle, it is safe to put the steamed bread slightly to ensure that the strip is not overloaded and all the gold can be recovered.
