Rod mills how they function Mine 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 to Rod mills accept feed up to about 50 mm 2 in and produce a product in the size range of
Grinding Circuit an overview ScienceDirect TopicsA combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh 45 Since solids concentration also affects the absorption two pairs of transmitters and receivers operating at different frequencies are employed to measure particle size and solids concentration of the pulp the processing of this information being performed by the electronics The Thermo
PDF SIZE REDUCTION BY GRINDING METHODSRod mills are less common than ball m ills for grinding minerals The rods used in the mill usually The rods used in the mill usually a high carbon steel can vary in both the length and the
What s the Difference Between SAG Mill and Ball Mill · Ball mills are fine grinders have horizontal ball mill and vertical ball mill their cylinders are partially filled with steel balls manganese balls or ceramic balls The material is ground to the required fineness by rotating the cylinder causing friction and impact The internal machinery of the ball mill grinds the material into powder and continues to rotate if extremely high precision
Small Ball Mills for Sale 911MetallurgistBall Rod Mills have greater capacity than most mills because the diameters of Ball Rod Mills are measured inside the liners while most mills measure inside the shell Ball Mill Capacity Tables SMALL TRAYLOR BALL MILLS Way back when Traylor was young we built our first ball mill and as for as we know that old mill is running yet grinding out dollars for its owner That s one

Grinding Mills Common Types· It will be noticed that the differentiation between ball mill and the tube mill arises only from the different length to diameter ratios involved and not from any difference in fundamental principles The rod mill however differs in principle in that the grinding bodies are rods instead of spheres whilst a pebble mill is a ball mill in which the grinding bodies are of natural stone or of
7 Major Differences between Ball Mill and Rod Mill · Now we will analyze the 7 major differences between Ball mill and Rod mill and tell you how to choose a ball mill and a rod mill Although ball grinding mill and Rod mill work on a similar principle they are still some big difference of each other 1 Different form and structure The cylinder shape proportions of two devices are different Generally the ratio of tube length to diameter of
Grinding Media 911MetallurgistRod Mill Grinding Rods Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill In selecting the appropriate ball charge the first objective is to determine that ball size which will grind the coarse particles most efficiently This size should be the largest ball size
Ball Mills Mineral Processing Metallurgy· Difference Between Ball Mill and Rod Mill Rod Mills The principal field of rod mill usage is the preparation of products in the 5 mm— mm 4 mesh to 35 mesh range It may sometimes be recommended also for finer grinding Within these limits a rod mill is usually superior to and more efficient than a ball mill The basic principle for rod grinding is reduction by line contact between rods
Tubular Ball Mills ScienceDirect· The design of different types of Tubular Ball Mills used for size reduction of crushed Run of Mine ores is described in some detail followed by descriptions and mathematical considerations of their operation Thus computations on the optimum amount of material to be charged the initial size of grinding and size distribution of the grinding balls at initial stage of operation and their

TECHNICAL NOTES 8 GRINDING R P KingThese mills exist in a variety of types rod ball pebble autogenous and semi autogenous The grinding action is induced by relative motion between the particles of media the rods balls or pebbles This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition In autogenous grinding machines

Optimum choice of the make up ball sizes for maximum · Fig 3 shows the typical variation of the S values with particle size x i for different ball diameters For the same amount of ball charge the number of balls in the mill decreases as the ball size increases Thus the S values are lower for larger balls However larger balls are capable of breaking large particles therefore the size at which the S value becomes maximum x m increases
Difference between Rod mill and Ball mill Fodamon MachineryFodamon engineers share the differences between ball mill and rod mill as follows 1 Appearance and structure The shape ratio of the barrels of the two mills is different The ratio of the length and diameter of the rod mill barrel is generally 2 and the inner surface of the liner on the end cover is a vertical plane There are various ratios of the length and diameter of the ball mill
Overflow VS Grate Discharge Ball or Mill Why Retrofit· Grate Discharge Ball Mills have shown 25% to 45% more tonnage ground and a substantial reduction in power consumed per ton of material compared size for size with overflow mills To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball mills There are essentially four types of rod mill
The difference between ball mill and rod mill Fodamon Category analysis different drainage methods In the ball mill there are commonly used lattice type ball mills and overflow type ball mills named from different mine discharge structure while rod mills do not use grid plate for mine discharge only overflow type and open type and the discharge end The diameter of the hollow shaft is generally larger than that of a ball mill
