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.
Principle of overflow ball mill: the main component is a cylinder with diameter and length at a reasonable by the transmission device, the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of
When particle size is required to be within mm, we generally use rod grinding machine whose maximum product size is smaller than mm and minimum size not less than mm.. Brief introduction to rod mill. Rod mill can be pided into dry rod mill and wet rod mill, so users can choose proper rod mill according to their own actual situations.
Rod mill is a kind of mill whose grinding body is steel rod. Generally, the rod mill is of wet overflow type, which can be used as the firstclass open circuit grinding, and widely used in the firstclass grinding of artificial stone sand, ore dressing plant and chemical plant.
Our Rod Mills are available in multiple diameters to fit the needs of your operation. Grinding, primarily by attrition, Rod Mills require comparatively low levels of power to operate. Rod Mills can be either wet or dry designs. Once replaced by AG and SAG mills, Rod Mills have had
Lab Overflow Continuous Rod Mill XMBL420#215;600 Overflowtype continuous rod mill can be used to continuously grind ores or study and test the grindability indexes of ores. It can also be used in ore dressing plants as ore grinding equipment or used in other industrial sectors to mill materials.
Rod grinder or rod grinding mill generally adopts wet type overflow and can be used in first class opencircuit grinding and widely used in the first stage grinding in artificial sand and stone, ore beneficiation plant, chemistry and power department.

Rod mill is a grinding equipment with steel rod as grinding medium. It is used to coarse grinding and suitable for fine crushing and coarse grinding in first stage of open circuit grinding. This machine include overflow rod mill, end peripheral discharge rod mill and center peripheral discharge rod mill, which could meet different requirement.

Autogenous Mill Introduction: A wet autogenous mill that materials as grinding media Particle Size: 200350mm Improvement: Highefficiency autogenous mill can realize the second and third stage crushing and screening, and part or all crushing and grinding of rod mill or ball power consumption, no dust pollution, less auxiliary equipment, easy production automation
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
Notes) The rod charging amount shall be limited up to 38% of the mill''s internal volume. Capacities listed in the above table are based on tests with ores of Wi=15KWH/MT and 80% of 15mm undersized particles, with wet grinding in closed circuit.
When used for coarse grinding, the processing amount of rod mill is higher than that of the ball mill with the same specification. The features of rod mill are that in the ore grinding process, the grinding media contact with the ore in a linear manner, so that it has selective grinding function.
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.
Introduction. The rod mill is loaded with the grinding media of steel bars. It consists of five parts including cylinder shell, feeding system, discharge system, main bearing and transmission system. It is available for both of the dry grinding and wet grinding fashion as the customers needs.
A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. The principal use for rod mills, which were invented to make ball mill feed in a wetgrinding rod millball mill circuit. Rod mills came into use in the United States beginning in 1900s and
