Since the cyclone through the ore into slurry pumps, it has no power, and therefore must be maintained during use of the pump to the mine for ore stable, maintained at a pressure within the calibration range (0.1-0.12Mpa), to avoid the pool pump evacuated cyclone gauge fluctuations.
In the mine for stable, non-fluctuating gauge cyclone case of cyclone underflow, overflow products were measured according to different ways of adjusting the different indicators, are summarized as follows:
First, the overflow occurs Coarse
1, the cyclone calibrated pressure range (0.1-0.12Mpa) inside the mine to increase the pressure by adjusting the pump to mine: to give mine pump frequency to transfer large number of non-overflow to run rough time.
2, by amplifying the cyclone grit mouth adjustment
When the pressure to mine within the scope of the calibration run rough phenomenon, can replace larger models grit mouth, in order to achieve reduction in crude run phenomenon.
3, check the cyclone underflow nozzle clogging
Cyclone grit mouth blockage can lead to a large number of overflow to run rough and have a huge impact to the subsequent process. When the cyclone pressure instability, violently shaking the body, running a large number of overflow traffic is very thick and the bottom is low, it should be checked in the mouth and grit cyclone feed body clogging phenomenon, if blockage should immediately clean up the demolition.
Second, the grit concentration is too low and there is a fine clip
1 reduced in the cyclone calibrated pressure range, and no overflow when Coarse ore pressure
By adjusting the pump to mine: to give mine pump frequency inverter transfer a small number, no overflow to run rough, smooth surface and high pump tank grit concentration can be.
2, by reducing the cyclone grit mouth adjustment
When the pressure to mine sand in the calibration range low concentrations, can replace the grit mouth smaller models to achieve the purpose of reducing the phenomenon of fine clip.
NOTE: When the ore concentration high, can lead to cyclone overflow to run rough, serious, grit clogs. When the ore concentration is too low, leading to the cyclone underflow concentration is too low, increase the load cycle. Supplemented by a ball mill and water amount adjustment processing station, will mine the concentration should be controlled between 35% -45%, to ensure that the cyclone is working properly.
