Chemical mixing efficiency in figures

Based on the mill results of more than 650 supplied mixing stations, chemical consumption reduces by 20-60% on average, water consumption in post dilution – by 100%. Optimal chemical mixing location improves the runnability and stability of the process, and makes wet end chemistry easier to control.
