The rod mill and the ball mill belong to the mineral processing equipment.They are similar in appearance and grinding principle, but there are differences in structure, performance and application. This paper summarizes the three aspects of the ball mill and the rod mill, hope to help you choose the right equipment for your own project.
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.
The rod mill usually uses 50 100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. The length of steel rod is 25 50mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8% 1%; the loading capacity of rod is about 35% 45% of the effective volume of rod mill.
Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed and has a higher power consumption. But for rod mill, grinding effect is better which need a lower rotate speed and has a lower power consumption. Xinhai produce all kind of ball mill and rod mill with high quality, you would interested in them.
Rod mills, ball mills, autogenous mills, and semi autogenous mills (SAG Mills) all have a number of lubricating and hydraulic systems, and they must work to keep mineral output high. The mill systems oil is subject to extreme levels of very fine particles, and many operators believe the plant should be shut down periodically to change the oil.
General Kinematics VIBRA DRUM174; Grinding Mills are proven in dozens of milling applications in the mining and mineral industries Each grinding mill is achieving impressive energy savings (35 50%), thanks to a unique rotational material motion that is more efficient than conventional ball or rotary grinding mills. New processes such as micron grinding and mechanochemical grinding give our
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.

Alibaba offers 2,402 rotary mining ball mill products. About 18% of these are mine mill, 1% are grinding equipment, and 1% are other fabrication services. A wide variety of rotary mining ball mill options are available to you, such as ac motor, dc motor, and stepper motor.
The overall design of ball mills and rod mills are compact, with simple operation and easy maintenance. But the both are different in performance and applications. In this article, the similarities and differences between ball mills and rod mills are analyzed from 9 aspects, and suggest how to choose ball mill or rod mill.
Rod Mill For Gold Ore Mining Ethiopia. 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 get price

Ball mill for sale In all the ore mining beneficiation and concentrating processes, including gravity separation, chemical, froth flotation, the working principle is to prepare fine size ores by crushing and grinding often with rock crushers, rod mill, and ball mils for the subsequent treatment.
Ball mills are similar in concept to the rod mill but are installed with steel balls in place of the rods. Ball mill Limestone,gold,silver,manganese,iron ore mining . Mining ball mill is widely used in powder making production line including silicate, refractory material, fertilizer, cement, normally steel balls.

Ball mill and rod mill solutions are available here at APT, providing an effective means for grinding and blending materials in preparation for mineral liberation, from rock to dust. APT specifies and designs the entire circuit around the mill, to ensure that the target product size is achieved. Ava
A Grinding Ball Mill is a type of grinder used to grind and blend materials for use in mineral processes. A Grinding Ball mill works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell. A Grinding Ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal.
At present, the most widely used grinding equipment in the dressing plant is ball mill and rod mill. As far as the working principle is concerned, both ball mill and rod millare the same. The grinding medium (steel ball or steel rod) installed in
Prominer provides ball mill / rod mill grinding system which is widely used in various types of ores beneficiation, electricity, cement and chemical industries. It can carry out dry or wet pulverizing and can meet demand for sustainable large scale production.
Ball Mills vs Rod Mills 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.
For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed and has a higher power consumption. But for rod mill, grinding effect is better which need a lower rotate speed and has a lower power consumption.
Short flash video at bottom of page showing batch ball mill grinding in lab. May have to click on browser quot;Allow Active X blocked contentquot; to play. A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.
The Ball Rod Mill Heads are oversize in section, heavily ribbed and are cast from electric furnace steel which has a strength of approximately four times that of cast iron. The head and trunnion bearings are designed to support a mill with length double its diameter.
