11.21 Phosphate Rock Processing 11.21.1 Process Description15 Primary size reduction generally is accomplished by crushers (impact) and grinding mills. Some classifiion of the primary crushed rock may be necessary before secondary grinding (rod milling) takes place. The ground material then passes through hydrocyclones that are oriented
 But note that the term ''rod mill'' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter.
New & Used Mining & Mineral Process Equipment For Sale
NEW AND USED GRINDING MILLS FOR SALE. Grinding is the second step of gold and mineral processing and the last stage of the comminution process. The product from a crushing unit is fed to a grinding mill in order to decrease the particle size for subsequent processing.
Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft.

The Steel Head Rod Mill (sometimes call a bar mill) gives the ore dressing engineer a very wide choice in grinding design.He can easily secure a standard Steel Head Rod Mill suited to his particular problem. The successful operation of any grinding unit is largely
The different types of grinding mills are based on the different types of tumbling media that can be used: steel rods (rod mills), steel balls (ball mills), and rock material (autogenous mills, pebble mills). ROD MILLS. The grinding charge in a rod mill consists of straight steel rods with an
GRINDING MILLSROD MILLSNew & Used Mining & Mineral
A rotating drum causes friction and attrition between steel rods and ore particles. The rods used in the mill, usually a highcarbon 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.
A Mill Relining Machine is a purpose designed machine used to remove and place liners in grinding mills. Typically, RME''s Mill Relining Machines find appliion in the larger AG, SAG, Ball and Rod mills throughout the hard rock mining regions of the world.
Shop our wide selection of UnUsed and Used Grinding Equipment including Ball Mills, SAG mills, Rod Mills & Vertical Mills. No matter what you are mining or processing, from rocks and metals to gold and oil shale, you''ll need heavy duty, industrial strength grinding equipment to grind down materials after the crushing process.
Semiautogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
The TM 300 Drum Mill is used for the preparation of granules and powders. The grinding process is performed either in dry or wet conditions. The drum mill can be operated either as a Ball or as a Rod Mill by using the corresponding module. A sufficient number of balls or rods is required for an effective grinding process.
One stage rod mill grinding is therefore suitable for preparation of feed to gravimetric ore dressing methods, certain flotation processes with slime problems and magnetic cobbing. Rod mills are frequently used as primary mills to produce suitable feed to the second grinding stage. Rod mills have usually a length/diameter ratio of at least 1.4.

From small Lab and Pilot Batch Mills to large Ball Mills, we source mills to suit your needs manufactured by Denver, , Allis Chalmers, Polysius, FL, Dominion, Hardinge, , and more. A ball mill is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.
MBS type rod mill is widely used for the grinding process which has high requirement for the uniformity of the ground final products in refractory, chemistry, metallurgy and glass industry, and it has also been used in building sand making industry in recent years.
Autogenous mills, or AG mills, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
China FTM® Grinding Rod Mill Machine for Sale Fote Machinery
The main usage of rod mill: it is widely used in grinding a variety of ores, such as quartz sand and tungsten ore grinding process to prevent excessive grinding. In the twostage grinding process, grinding rod mill can be used in the first stage, when rod mill have large capacity and high efficiency. In some cases, rod mill can replaces cone
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
In the grinding process, the grinding media make a line contact with ores, so it has a certain effect on selectivity and grinding. The particle size of dry rod mill product is relatively uniform. When used for coarse grinding, the processing capacity of rod mill is better than that of other ball mill with same specifiion, and the reverse is

EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.
