The high underflow concentration may be caused by the feed slurry concentration or the underflow opening is too small. You can add an appropriate amount of water to the feed first. If the underflow concentration is still large, you need to replace the larger underflow opening.
The "fine underflow clamp" may be caused by the underflow orifice wear, the underflow orifice is too large, the overflow pipe diameter is too small, the pressure is too high or too low, it is necessary to adjust the pressure first, and then check whether the underflow orifice is worn or replaced A small underflow port is gradually adjusted to normal production state.
If it is found that "overflow is running thick", first check whether the underflow port is blocked, and then check the feed concentration, and then adjust it according to the specific situation. If the underflow port is blocked, open the underflow port to clear the blockage.
When the grit nozzle is in the shape of a rope, the size of the grit nozzle can be appropriately increased, and the cyclone operation can be stopped to clean up the blockage. The above are the common failure causes and countermeasures of aggregate crushing value conclusion.
