Rod Mill Grinding Rods. Rod mill grinding rods of all sizes and length. High hardness, range is 45~55HRC. Low bending, less than 1.5mm/m. Dense microstructure,Bainite +Pearlite+Carbide. Low breakage rate, more than 15000 times/ 3.5m. Low unit consumption, 40% reduction compared to unprocessed round steel.A 3 m × 3 m rod mill was charged with 100 mm diameter steel rods having a bulk density of 5.2 t/m 3. In the stationary state, the height of the charge occupied two-thirds of the radius and the porosity of the bed was 35%. Determine. 1. the mill volume occupied by the charge (J), 2. the fraction of the mill volume occupied by the ore if U = Tubular Rod Mills ScienceDirect

Rod Mill. Rod mill is very similar to ball mill by cicemech Oct
Rod mill is very similar to ball mill except for the use of steel rods as grinding media. Steel rods grind the ore by rolling and rotating in the rod mill. The feeding of rod mill is about 50 mm2. In the first grinding stage. If the rod mill is used for the first stage grinding equipment to grind materials from 20~6 mm to 3~1 mm in the two-stage grinding process, the production capacityStructure of rod mill LinkedIn

Evaluation of a laboratory rod mill when grinding bituminous coal
The tests were conducted using a 193.5 mm diameter and 245.0 mm long laboratory rod mill, which contained steel rods at a volume loading of 23%. The mill was operated at 70% of critical speed for various grind times. A locked-cycle test was also performed to simulate continuous grinding conditions. The grinding was characterized 1The 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 usually made of high carbon steel containing 0.8%-1% carbon. 2The loading amount of the rod is about 35%-45% of the effective volume of the rod mill.High-Efficiency Rod Mill Machines for Optimal Mineral Processing

2. The discharging granularity of rod mill is evener and the output is higher. It is widely used in the grinding process that has higher requirement for the uniformity of the final products in wear-resisting Rod mill is mainly used for processing and crushing raw materials such as feldspar, quartz and ore, and also for the fine and The Bond rod mill work index ( Wir) is measured using Bond´s standard rod mill grindability test, which is conducted in locked-cycle mode to emulate the continuous closed-circuit operation. Besides the labor-intensive conduct of the test, which typically requires from 5 to 10 cycles for reaching steady-state, it normally requires 8–20 kg ofSimulating the Bond rod mill grindability test ScienceDirect
