Faktor-Faktor Yang Memengaruhi Efisiensi Primary Forward Cleaner Di Pulp Dryer 3
ABSTRACT Cleaner efficiency is defined by the number of contaminants in the reject section divided by the number of contaminants in the feed section, meaning that the fewer contaminants present in the reject section, the better the efficiency value. Likewise, vice versa, the more contaminants left in the reject section, the efficiency value will decrease. Therefore, it is necessary to pay …
