The SAG Mill is a machine added by Ender IO. It uses Redstone Flux (RF) to grind (or mill) items into their crushed variants, like Ores into Dusts. The SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs.

Our top quality sag mills will help to grind your items down into other items. Our products can achieve the same size reduction like several stages of crushing.

AG/SAG mills are normally used to grind run-offmine ore or primary crusher product. Feed size to the mill is limited to that size which can be practically conveyed and introduced into the mill. The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a ball mill, pebble mill, or

Because SAG mills rely both on the ore itself as grinding media (to varying degrees) and on ore-dependent unit power requirements for milling to the transfer size, throughput in SAG circuits are variable.

Semi-Autogenous (SAG) Mills. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15%, and is primarily been used in the gold, copper and platinum industries but also in the lead, zinc, silver, and nickel industries. Autogenous (AG) Mills. Autogenous grinding involves no grinding media as the ore itself is the grinding media.

Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes.

SAG mills are essentially autogenous mills, but utilize grinding balls in addition to large rocks to aid in grinding. A SAG mill is generally used as a primary or first stage grinding solution. SAG mills are used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries.
