Scoop Feeders for Ball-Rod Mills are made in various radius sizes. Standard scoops are made of cast iron and for the3′ size a 13″ or 19″ feeder is supplied, for the4′ size a 30″ or 36″, for the5′ a 36″ or 42″, and for the6′ a 42″ or 48″ feeder. Welded steel scoop feeders can, however, be supplied in any radius.

Ball Mill - an overview | ScienceDirect Topics
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially5–10 cm diameterbut gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

First, a JarMillgrindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feedsizeto the requiredproduct size. The second test, a Bond Work Index determination, results in a specific energy value (net Hp-hr/t) from an empirical formula.
