The difference between a rod mill and a ball mill cement . The difference between ball mill and rod mill shape and structure the ratio of tube length to diameter of the rod mill is generally , and the inner surface of the lining plate on the end cover is vertical plane the ratio of cylinder length to diameter of ball mill is small, and in most cases the ratio is only slightly greater than
Discover MoreDifference between Rod mill and Ball mill - Fodamon . 2020-5-27 The diameter of the hollow shaft at the discharge end is generally larger than the ball mill of the same specification. 3. Grinding media Rod mills usually use steel rods with a diameter of 50mm-100mm as grinding media, while ball mills use steel balls as grinding media.
Discover MoreOct 12, 2017 1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.
Discover MoreThe finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm. However, the rod mill fine grinding fineness is about 0.833-0.147mm. In terms of the fineness of the ground material, the ball mill has a finer handling ability.
Discover MoreThe Sag mill uses lifting plates along the interior of the drum, which lift material throughout the rotations, causing them to fall onto one another to promote crushing. A ball mill has many steel or porcelain balls put in a drum to grind the feed between balls and between the balls and drum inner wall as the drum rotates.
Discover MoreWhats the Difference Between Ball Mill, Rod Mill and SAG ... different grinding media of ball mills, rod mills and SAG mills. Crushing ratio Comparison. The biggest feature of SAG mills is the large crushing ratio, which can crush and grind the materials to 0.074mm at one time, accounting for more than 20 to 40 of the total product. More

Discover MoreThe second equipment was measured during a maintenance stop. It was a ball mill installed in a bauxite processing plant. The third equipment was a SAG mill with 32 9.75 m diameter, installed in a gold and copper plant. The measurements in the SAG mill were conducted after a grind out.
Discover MoreApr 24, 2018 Grate Discharge Ball Mills have shown 25 to 45 more tonnage ground and a substantial reduction in power consumed per ton of material compared size for size with overflow mills. To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball mills. There are essentially four types of rod mill ...
Discover MoreThe purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 81. Feed ROM up to 1.5 m. Product -300mm for transport to -200mm for SAG mill
Discover MoreApr 01, 2013 The JKMRC has been studying and modelling industrial AG and SAG mills for over 40 years, but the ability to simulate the effects of blending hard and soft components on mill performance remains quite limited.In an effort to quantify these effects for modelling purposes, a series of laboratory, pilot scale and full scale tests, using multi-component feeds were conducted under the AMIRA P9O
Discover MoreRod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock pebbles as the grinding media to cause friction and attrition between the pebbles and ore material. Pebble mills may be used when metal balls must be avoided. Autogenous grinding AG and semi-autogenous grinding SAG mills use the material to ...

Discover MoreJul 03, 2017 Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined.
Discover MoreApr 01, 2016 In its original form Morrells model used a different media charge shape to that in Fig. 1 Morrell, 1992 and was configured to consider the cases where slurry was contained within the grinding charge as in a typical grate discharge AGSAG mill Fig. 2a or where it additionally formed a large slurry pool as occurs in all overflow ball mills ...
Discover MoreIn cases where there are a lot of clays present or there is high moisture, an AG autogenous grinding or SAG semi-autogenous grinding mill may be appropriate. For smaller throughput scenarios, a three-stage crushing plus rod mill plus Vertimill may make the most sense. It all depends on the ore characteristics and the overall plant requirements.

Discover MoreIn this example, the OWi of the SAG mill was found to be 30 higher than the ball mill, thus suggesting that the SAG mill was less efficient than the ball mill. The apparent inefficiency of SAG mills when using Bond analysis is widely understood to be due to the difference in the slopes of the size distributions. In contrast, when the SSE75 was ...
