Welcome to inquire! Contact: Niu Yang. Rod Mill Introduction: Rod mill called the wet-end perimeter row of ore type rod mill, large ceramic hollow shaft feed mill, surrounding the discharge end of discharge, rod mill and ball mill structure is basically the same, the difference is that the former The long barrel diameter L / D is relatively large, the end of discharge does not discharge mine grid plate, the larger port of discharge for the successful discharge, using Stick media for round bars, its length 100-150 mm shorter than the mill shell When used for slag grinding process medium filling rate of 30% or less, rod mill with large diameter hollow shaft hollow shaft, alloy pad support of 300 mm or less material can be smoothly out of material, with the mill feed size of mineral change, rod mill discharge mode can be changed, crushing grinding material, can be a simple operation caulking around the discharge port, the discharge end of the hollow shaft by the material, can be changed to adjust the amount of feed production, in order to achieve Buying a suitable discharge size ceramic ball mill, rod mill for rapid discharge characteristics, Dahua machinery used in the cylinder aspect ratio is large (more than 2/1), mainly to extend the grinding time in order to facilitate iron slag full separation, the other when the rod mill caulking around the discharge holes for small-diameter material crushing grinding, replaced by the discharge end of the hollow shaft when the material is still able to maintain acceptable discharge size. At present, the domestic iron mining when similar materials grinding, continuous access to material type iron mill exclude a class of "hard grind particle" approach are: from the mill operation takes in the material lattice panel on "gravel window", forced out "hard grind particles", but is limited to -80 mm in diameter, it is difficult to achieve the grinding needs of existing materials, once out of the lower feed mill grinding efficiency, equipment, huge ceramic ball, is not conducive to the process link, using the surrounding row Mine rod mill, to meet the current needs of small chunks of production of steel slag grinding. Some people think that the principle of ceramic ball, ball handling spherical bush and hollow shaft journal with the majority of small backlash good, which empty into the film when the shaft is not easy to lead, or the occurrence of localized surface spherical bush burning, often manifested in the oil can not be successfully ground into the hollow shaft journal and spherical bush contact area, many people think is a spherical hollow shaft journal tile fitting backlash is too small, in fact, not necessarily spherical hollow shaft journal tile and fit backlash in national building materials industry Standard JC 334.1-94 in the first 4.3.2.la relatively clearly defined, with the backlash must form a more standardized wedge backlash, it helps guide people to the oil, and approximately equal thickness or stepped backlash not conducive to import oil, almost equal thickness big backlash has tile edges on both sides of the oil pouring into the tendency is not conducive to the formation of an oil film.
