Uses of a ball mill liner The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.In this case, the SAG mill design can do that. In general, the SAG mill manufacturers will control the addition amount of medium such as steel ball at 2 8 , so that the capacity of semi SAG mill to process materials can be increased by 10 30 . The SAG mill liners wear will increase by 15 due to the impact of medium such as steel ball during.
The ball mill, but they can also be used as a one stage grinder. The absence of, or reduction in the number of, balls means they can be less costly to operate than ball mills. SAG mills of over 40 foot diameter have been constructed. Like the ball mill, the AG SAG mill will have a critical rotation speed above which grinding ceases. Mill motor.Apr 09, 2015 In this case the mill is then referred to as a semi autogenous (SAG) mill. The process can be carried out wet or dry. Fig 1 Cross sections of a rod mill and a bar mill. Ball mills. Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. ranging in size up to 125 mm for larger mills.
SAG is an acronym for semi autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21 . [6] [7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. [8] A SAG mill with a 44′ (13.4m) diameter and a power of 35 MW (47,000 HP) has been.SAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency through.
Have the same F80 but clearly have different distributions. These would When the feed size of a SAG mill becomes coarser, AG SAG mills and ball mills within conventional processing.Ball mill When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size.
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller Traylor SAG AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.The design of mill liners and SAG mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput.
