2016-5-31 Under wet grinding conditions of course the problem of dust is eliminated. The grinding action of a rod mill is line contact. As material travels from the feed end to the discharge end it is subjected to crushing forces inflicted by the grinding rods.

Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.

2020-4-11 When rod mill user’s steel grinding rods are broken, they could find out the reasons from the following aspects (for reference only):. 1. The strength and hardness of steel grinding rod is not up to standard;. 2. Corrosion of steel grinding rod caused by too high content of sulfur and phosphorus in rod mill;. 3. Steel grinding rod wear too fine and rod

2016-1-1 A wet overflow rod mill was operated at 75% of the critical speed and found to draw 8.5 kW/t of rods when the mill was loaded to 35% of its volume. A certain number of rods were then removed and the mill power increased to 8.95 kW/t of rods.

The rod mill also tends to suffer from accelerated drum liner and lifter wear due to the increased weight of the rods. Mills of various types have been used for centuries to break solids or coarse particulate materials down into finer finished products.

2012-11-26 Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods

2015-8-13 The location of the sizing mill is important to allow time for the rod to be controlled cooled and equalized prior to the final reduction, thereby reducing the risk of over-heating of the rod core. This is crucial for special steels which are sensitive to grain coarsening at high finishing temperatures.

2021-3-8 Center and side discharge rod mill can grind ores coarsely because of its structure. This kind of rod mill can be used for wet grinding and dry grinding. "A rod mill is recommended if we want to properly grind large grains, because the ball mill will not attack them as well as rod mills will." ①. End and side discharge rod mill

2021-6-16 Rod mills are very similar to ball mills except for the use of steel rods as grinding media. In the rod mill, steel rods grind the ore by rolling and rotating. The feeding of rod mill is 50 mm, and its output particle size is -4 to 35 mesh. Rod mill produced by Fote Application fields of rod mill Applications of rod mill

2021-6-18 “A taconite plant may have as many as 18 rod mills with one rod alone weighing as much as 500 Ib (227 kg). Tumbling around in the mills with the hard taconite wears away the rods and balls and need to be replaced frequently.” This is a costly and energy-intensive process and the waste rods and balls are a disposal problem, according to NRRI.
