### Laboratory Ball Mill Scale

Closed circuit milling at small scale (Bond mill sizes) provides opportunities to simulate mineral deportment issues, which you can't do in a basic batch mill except by doing locked cycle test, which can be a messy task for wet milling. A simple elutriator is probably the best substitute for a hydrocyclone for closed circuit laboratory milling.
