The ball size distribution (BSD) in a mill is usually not known, as the measurement of the charge size distribution requires dumping the load and laboriously grading the balls into size classes. Fortunately we had one set of data as discussed below. The general non-availability of BSD necessitates the use of ball wear theory to estimate …

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 ...

Grinding. This is the second size reduction process in a pellet plant. In order to improve the wood pellet quality and output and lower the energy consumption of the pellet mill, we use a hammer mill to grind the raw materials into small particles with a diameter less than 5mm. The smaller the raw materials are, the better wood pellet we …

Ball mill. The grinding medium of the ball mill is in point contact with the ore, which has both impact force and grinding force. The production capacity is high, and the fineness of the material is high. Rod mill. The grinding medium of the rod mill is in linear contact with the ore.
longest run is 10 tonnes. The plant has two surge bins over the pellet mill, multiple die changes per day and stringent flushing requirements between production runs. The calculated efficiency of the 40 TPH pellet mill is about 85-95% in the single-species plant, while the efficiency for the multi-
1. For a new pellet mill or new pellet die, it is not easy to form pellet. Then flushing of the new pellet die is needed to help the pellet mill to form pellets effectively. To flush the die, mix fine sand in with the raw material along with a generous amount of oil. Recycle this mixture through the machine after it is discharged.
Rod mill liners are also generally of alloyed steel or cast iron, and of the wave type, although Nihard step liners may be used with rods up to 4 cm in diameter. Lorain liners are extensively used for coarse grinding in rod and ball mills, and consist of high carbon rolled steel plates held in place by manganese or hard alloy steel lifter bars.
