Rod mill or ball mill energy consumption analysis

Wet grinding rod mills are normally used in the mineral processing industry. Rod mill size depends on the feed and product size, capacity, type of grinding circuit and the power required to achieve the grind. It is important that the rods stay essentially parallel to one another. If rods become misaligned, grinding action is lost and more importantly,
Combination crusher,China spiral ,China spiral classifier and other machines are the main ore dressing equipment on the market. rod entanglements will occur. For this reason, rod mills are designed with their length roughly 1.Ore separating line,Combination crusher and other machines are the sand making equipment, 3 to 2.0 or more times than their diameter.And rod mills normally carry 35 to 65% rod charge by volume. Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential grinding of coarse material and minimizes production of slimes.For an equivalent grind, a rod mill uses less energy than a because of the lower speed and better contact between the media and ore.

Hammer crusher is one of the most important crushing equipment which is widely used in mining, chemical,Combination crusher metallurgy, building materials, electricity and other industries. The hammer is the main wear parts, its quality direct impact the crushing efficiency of hammer crusher. In addition to being hit, the hammer is also impacted by the material during crushing stones.Combination crusher So after long-term repeated use, the hammer’s surface will change. Currently the majority of hammer is made of high-manganese steel. Because the poor abrasion resistance, bad wear-resistant and short life of this material,Ball mills the hammer needs to be replaced frequently.
However, statistical information on S–N curves for different structural details are relatively well established. As a matter of fact, it is possible to calibrate the FM formulation with the use of S–N curves and Palmgren–Miner’s rule,

VSI ,VSI sand maker,Cement and other machines are the main ore dressing equipment on the market. and employ the stochastic characteristics of S–N curves and Palmgren–Miner’s rule to represent the uncertainties of random flaw propagation predicted by the calibrated FM formulation.Artificial sand maker,Artificial sand maker and other machines are the sand making equipment, Traditionally, this calibration is normally performed by equaling the fatigue reliability or the fatigue life obtained by applying the FM approach with that estimated by Palmgren–Miner’s rule, with the use of S–N curves.
