INVT's intelligent frequency conversion solution for ball mills realizes adaptive control of the ore grinding process, reduces startup-shock impact and energy consumption, improves grinding efficiency, ensures continuous and safe production in coal preparation, and achieves a high comprehensive energy-saving rate.
Excessive energy consumption: Power-frequency pumps operate at a constant speed, resulting in high no-load losses and a large proportion of electricity costs.
Large pressure fluctuations：Manual pressure regulation responds slowly, and pipeline shocks easily cause pipe bursts and leakages.
High maintenance costs：Frequent damage to mechanical seals and frequent downtime for spare parts replacement.
Lack of intelligence: Liquid level and pressure rely on manual inspection, and failures cannot be predicted in advance.
