The third type of mill that I mentioned was an AUTOGENOUS MILL, this type of mill uses a completely different type of grinding media; the rock itself In conventional milling, the ore is crushed to, plus or minus, 3/8 of an inch, before it is put into a mill for grinding. In a autogenous mill the ore is fed directly into the mill from either the primary crusher or the mine itself.
Photo of Autogenous Mill at a copper mine. Autogenous Mills operate, mechanically, similar to the ball mill. They differ in the media they use to break or grind the ore. Autogenous Mills use large particles of ore instead of steel or other balls for grinding media. Autogenous mills use large pieces of ore as grinding
Simplifying wet grinding with liming AG/SAG mills AG/SAG mills are often the optimum solution for wet grinding (achieved in a slurry 50 to 80 percent solids). AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill.
Autogenous grinding implies by definition the grinding of ore by itself. Autogenous mills can be operated in tandem with secondary grinding mills (either a ball or a pebble mill) or they can be operated as single-stage mills in closed-circuit with a classification or sizing device.

In this case, Xinhai efficient autogenous mill solved these problems effectively. Xinhai efficient autogenous mill can achieve two and three stage crushing, part or all crushing of ball mill and rod mill, it is suitable for the coarse grinding after coarse crushing.
High-efficiency autogenous mill can realize the second and third stage crushing and screening, and part or all crushing and grinding of rod mill or ball mill. Low power consumption, no dust pollution, less auxiliary equipment, easy production automation, and stable particle size.
Another purpose is a grinding mill of the type described including means for internal separation of the finely ground product. Another purpose is a grinding mill of the type described having a pair of grinding chambers, although a single chamber is also satisfactory. Another purpose is an autogenous grinding mill having a peripheral discharge.
Semi-Autogenous Mill For Grinding Feldspar And Quartz Hongji Ball Mill is a key equipment to grind the crushed materials, which is widely used in the manufacturing industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics.
Another purpose is an autogenous grinding mill hav ing a peripheral discharge. Another purpose is a mill for autogenous grinding utilizing spaced lifter bars within the mill, the height and spacing of the lifter bars being regulated to obtain maxi mum grinding efficiency.

SAG is an acronym for Semi-Autogenous Grinding. SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. A SAG mill is generally used as a primary or first stage grinding solution. Attrition between grinding balls and ore particles causes grinding
