Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.

performance of the rod mill Stone Crushing Equipment The building aggregates equipment of AC includes not only a series of single equipment of coarse crushing, intermediate and fine crushing, sand making and shaping, but also a batch of standardized design products of production line on the basis of many years of experience.

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

The rod of diameter from 50 to 100 mm is often used as the grinding medium, and the filling rate of rod mill is 35% to 45%, while filling rate of ball mill is 40% to 50%. Rod is mainly made of several materials: A High carbon steel

The following equation is used to determine the power that a rod mill should draw. The Bottom Table lists many of the common size rod mills giving speed, loading and power data. The rod mill motor power is in horsepower at the mill pinionshaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6%, and adjust ...

The rod mill is named after the grinding body is filled with steel rods. The rod mill is generally a wet overflow type, which can be used as a firststage open grinding, widely used in artificial stone sand, concentrating plants, chemical industry. Firstgrade grinding in the power sector of the plant. Below, everyone and Xiaobian to understand its use and performance characteristics.

Mills usually operate in the range 65 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill .

The 1m mill was used to investigate the effects of three lifter configurations, namely Hi (High), Rail and HiLo (HighLow), and mill speeds on the mill performance.

Jul 03, 2017· When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the ...

The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small pieces, so that they can exit the mill. The energy consumed by rod mills could be from 10 to 30% higher than the energy consumed by bar mills and this is for comparable performance.

Usually, the technological characteristics of highspeed wire rolling mill can be summarized as continuous, highspeed, nontwist and aircooling, among which highspeed rolling is the most important one. The product characteristics of highspeed wire rod mills are the excellent performance of large plate weight and high precision.

Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.

In general, the efficiency of a rod mill is about 15% lower than that of a grid mill of the same specification. These working characteristics of the rod mill determine that it is suitable for the processing equipment of tungsten ore, tin ore and other brittle materials to reduce overcrushing and improve the recovery rate of sorting operations.
