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 [5]

Rod Mill Manufacturer. The Strommashina plant manufactures reliable rod mills designed for long-term fault-free operation. The rod mill is grinding equipment, it is a milling device used for coarse grinding (up to 500 to 1000 mm) of the concentrating raw material before the finish grinding in the ball mills.. The Strommashina plant manufactures a wide range of the rod
A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action. An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. Although similar in operation, a rod mill is often more effective
Nov 29, 2018 Selecting the ball mill and rod mill according to the granularity and effect of the finished product The processing capacity of rod mill is greater than that of the ball mill when the product size is 1-3mm in the coarse grinding process, while the grinding effect of ball mill is greater than that of the rod mill when the product size is less

Nov 27, 2015 Good figures for rod and bar mills are 90 % to 93 %, for structural mills, the good mill utilization figures are 75 % to 78 %. If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour

Rods. Rods come as long stock (typically, 1 m - 3 ft. - or longer) that are cut to blanks by the machine shop. The limiting dimension here is the diameter of the rod. The table below summarizes the most common aluminum and steel plate thicknesses that can be found in the warehouse of every machine shop

Apr 07, 2018 How to Size a Rod Mill Grinding Rod Diameter ...
Standard conditions for determining the work index of rod mills under laboratory conditions are: mill size = 305 mm (internal diameter) 610 mm (internal length) with wave type lining. material dry mineral. quantity − 1250 cm 3 (tapped down to give a reproducible bulk density)
Rod mills usually require greater operator attention. It is important that the rods stay essentially parallel to one another. If rods become misaligned, grinding action is lost and, more importantly, rod tangles occur. Maximum rod length is limited to about 6.1 m (20 ft). This in turn limits the length, diameter, and capacity of rod mills. The heavier rods acting upon the lifters and liners
Mar 08, 2021 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:
The Essa ball and rod mill range includes: Essa BM Series Laboratory Ball Mills – ideal for producing finer particles. Available in 6.3 L, 12.3 L and 21 L barrel volumes. Essa RM Series Laboratory Rod Mills – suitable for larger and more coarse materials. Available in 7.8 L, 14.7 L and 25.4 L barrel volumes
steel bars and wire rods are manufactured in a wide variety of grades. Thus, they are characterized by small volume production in various sizes and grades. At the Mill, wire rods (5.5- to 34-mm φ) and bars (22- to 62-mm φ) are rolled by one strand. Wire rod is finish-rolled by a no-twist mill (NT mill) and wound by a laying head. A thicker wire rod
Nov 27, 2015 A wire rod rolling mill, for example, gradually reduces the cross-sectional area of a starting billet (e.g., 150 mm square, 10-12 meters long) down to a finished rod (as small as 5.0 mm in diameter, 1.93 km long) at high finishing speeds (up to 120 m/sec).
