Disclosed are various embodiments of an auger-style treatment tank equipped with instrumentation. In one embodiment, an auger treatment tank includes an auger configured to rotate within treatment liquid in the auger treatment tank. The auger includes an auger shaft and at least one auger flight coupled to and helically disposed about the auger shaft. The auger treatment tank also includes one or more sensors configured to provide data directly or indirectly indicating a torque transmitted to the auger to effect rotation.

A grinding liquid mixing and supplying system comprises a stock solution barrel, a stock solution circulation tank, a grinding liquid mixing tank, a grinding liquid supplying tank, which are configured with pipelines that interconnect each other; and capacitive liquid level sensors connected in parallel with these tanks. The stock solution circulation tank is provided with a first pipeline, the first pipeline is provided with a first filter and a first pump, and the first pipeline allows the stock solution to flow out from the stock solution circulation tank, to be pressurized by the first pump, to be sent to the first filter, and to flow back, so as to be circulated and filtered. The capacitive liquid level sensor detects a liquid level and monitors whether the liquid is normal in the tanks, so as to maintain and ensure the output quality of the grinding liquid.
