  • Rod Mills Mineral Processing & Metallurgy

    The following cost advantages should be considered when evaluating rod mill grinding: Rod Mills use low cost grinding media. Less power is required since grinding rods are not cascaded and operate at lower peripheral speeds. Higher grinding efficiency is obtained since there is less void space in a rod charge compared to any other grinding media. This also results in lower steel consumption

  • Grinding rods Magotteaux

    Tailored rods for your mill. Grinding rods are high quality steel rods that have undergone various heat treatments to maximize the wear and impact resistance. Our strong expertise is enabling us to select the right alloy to fit your rod mill and minimize your costs. Improved abrasion and impact wear resistance thanks to optimal distribution of higher hardness over the cross section ; Increased

  • Rod mills, how they function Mine Engineer.Com

    Rod mills are very similar to ball mills, except they use long rods for grinding media. 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 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of

  • Rod Mills for coarse grinding FLSmidth

    Grind coarse feed material with a reliable Rod Mill that won't over-grind. If you are in need of an application for coarse materials like limestone, potash, coal, phosphate and bauxite, you may be looking for a solutions like Rod Mills. Rod Mills are particularly useful, if you run a low tonnage operation and are looking for coarse product.

  • Rod Mill an overview ScienceDirect Topics

    Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. 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

  • Grinding Mills: Ball Mill & Rod Mill Design & Parts

    Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding

    Shandong ShengYe Grinding Ball Co.,Ltd is a professional factory specialized in the production of forged and hot rolled grinding balls and grinding steel rods for ball mill. Annual output is 100,000tons. 95% products exported more than 40 countries.

  • New & Used Rod Mills for Sale Ore Processing Equipment

    Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon 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. Our

  • Bond Rod Mill Index Test JKTech

    The Bond Rod Mill Work Index is a measure of the resistance of the material to grinding in a rod mill. It can be used to determine the grinding power required for a given throughput of material under rod mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen. Sample Requirements: A minimum of 20 kg of material crushed to nominally minus 19 mm

  • Tubular Rod Mills ScienceDirect

    The grinding action for size reduction of particles is almost similar to ball mills, but in this case the entire length of a rod is responsible for breakage of particles spread along the length of the mill. The breakage occurs more by a cascading action than by cataracting. The rods fall from a height and roll down the mill, so the rods impart an impact force as well as an abrasive action. As

  • What is a Rod Mill? (with picture) wiseGEEK

    The rod mill is generally more efficient than the ball mill due to its more effective cascading action and the greater bearing surface offered by the rods. This means it can operate at lower speeds and with less grinding agents and producing less undesirable slimes byproduct. Rod mills do, however, require more attention during operation to prevent rod tangles and are generally ineffective at

  • Grinding Ball-Grinding Rod-Forged Steel Grinding Ball

    Our wear-resistant steel grinding rod is specially used in rod mill for mineral processing. It has high hardness (HRC45-55) and strength, which is better than ordinary round steel. The wear resistance is increased by at least 50%, which is extremely high. High cost performance makes our grinding rod widely used in major rod mills in China. SEE MORE.
