One of the advantages of a rod mill is that it can handle a higher capacity than a ball mill of the same size. Additionally, the grinding medium in a rod mill is more uniform than that in a ball mill, and this can be beneficial for certain materials. Rod mills are also relatively low-maintenance, making them a cost-effective option for many ...
The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new …
The proper feed for the pelletizing plant must have iron and the Blaine number more than 67 % and 1900 cm 2 g-1 and sulfur content less than 0.1 %, respectively.
Two 11½'x 18′ dry grinding center peripheral dis-. charge rod mills were installed each to grind an average of 80 long tons per hour of minus 3/16″ iron ore fines to 2 to 3% plus 20 mesh with 35 to 40% passing 325 mesh. This ore is a coarser grained and more gritty type ore than the ore ground in the plant described above.
Typically R = 8. Rod Mill Charge: Typically 45% of internal volume; 35% – 65% range. Bed porosity typically 40%. Height of bed measured in the same way as ball mills. Bulk density of rods = 6.25 tons/m3. In wet grinding, the solids concentration 1s typically 60% – 75% by mass. A rod in situ and a cutaway of a rod mill interior.
Generally, this type of mills is used for preliminary grinding step before the grinding by ball mill or grinding with less excessive grinding for gravity classification. The …
After grinding the material for 0.5, 1.0, 2.0 minutes, etc., the mill contents were discharged into a steel trough. Each of the rods as well as the mill insides was carefully washed with water to keep ground product loss in handling at a minimum. This is required at finer grinds, especially.
Rod Mill Design Calculations. EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open …
Rod mills are widely used in the mining industry for the purpose of crushing and refining ores. They find various applications in the mining sector, including: Ore Crushing: Rod mills are commonly…
Rod mill features. 1 The rod mill usually uses a steel rod with a diameter of 50-100 mm as a grinding medium. The length of the steel rod is 25-50 mm shorter than that of the cylinder, and is ...
2. Grinding medium. Rod mill commonly uses steel rods with diameter of 50-100mm as grinding medium, while ball mill uses steel balls as grinding medium, and the difference of grinding medium is the main difference between them. The steel balls of ball mill are in point contact with each other, while the steel rods of rod mill are in line ...

Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...
Reliable of rolling wire rod from 4.5 to 27 mm diameter at a constant speed of 120 m/s (design 140 m/s), entry temperature of 750 °C, product tolerances up to ±0.10 on Ø 5.5 …
The entire weight of the rod or rods will be transferred to that spot. The result may be a broken liner. Of course the condition of the mill liners will be a major factor in its survival. Even if the liner doesn't break, the impact will begin to loosen the bolts that hold the liners in. Once these bolts are loose they will begin to leak.
The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. 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 ...
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for …
To prevent most conditions leading to rod charge tangling, the generally recommended relationship of rod length to mill diameter Inside liners is 1.4 to 1.6. When this ratio becomes less than 1.25 the risk of tangling Increases rapidly. For rod mills larger than 3.8 meters (12.5 feet) in diameter rod availability and quality have to be considered.
