However, this scheme prolongs the service life of the electrode to some extent, but increases the burden of the pit pump, not only increases the power consumption, but also aggravates the wear of the pump parts, especially when handling the slurry containing particles, the wear problem is particularly serious, so it needs to be improved and optimized.
