High hardness, range is 45~55HRC Low bending, less than /m Dense microstructure, Bainite +Pearlite+Carbide Low breakage rate, more than 15000 times/ Low unit consumption, 40% reduction compared to unprocessed round steel Category: Grinding Media Description Description
Drum Mill TM 300. 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.
End peripheral discharge type: It is generally used for dry ore mill. His products are coarsegrained. Rod mills can also be used for wet grinding. A high gradient and better flow rate can be obtained by using the peripheral rod mill. His product size is about 25 mm. Central peripheral discharge type: It can be used for wet and dry grinding.
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. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. ... A SAG mill is usually a primary or first stage grinder. SAG ...
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 initial diameter of 50100 mm.

Laboratory rod mill is commonly used as a grinder for the mineral feasibility study and for heavy concentrate reduction. Rod mill also is suitable for wet and dry grinding of fine ore and other materials in the laboratory, grinding of artificial heavy sand and ore in metallurgy, chemical light industry, agriculture and geological experimental work.
A rod mill may be regarded as containing a series of grinding zones in which both breakage and screening occur, such that the coarse size ranges are progressively eliminated. The main breakage mechanism is shatter breakage, resulting from particles striking against each other.
