Abstract

The invention relates to a vertical roller mill, which comprises a vertical main rotating shaft arranged on a machine body, wherein a speed reducer and a motor are connected to the lower end of the main rotating shaft sequentially; a grinding bowl is arranged at the upper end of the main rotating shaft; the upper part of the inner side of the grinding bowl contacts a plurality of grinding rollers; the grinding rollers arranged on the grinding roller shaft by a bearing; the grinding roller shaft is connected to one end of a rocker arm; the middle part of the rocker arm is hinged to the machinebody; the other end of the rocker arm is hinged with the upper end of a hydraulic cylinder; the lower end of the hydraulic cylinder is arranged on the machine body; a central feed pipe which aligns with the grinding bowl downwards is arranged on the top of the machine body; and a discharge hole is formed below the grinding bowl on the machine body. The vertical roller mill has the advantages of convenience for oil injection, high yield, low energy consumption, large processing capacity, high efficiency and sealing performance, adjustable grinding force and the like, is easy to maintain and overhaul, and the technical problems of enrichment of steel slag and iron granules, high abrasion of the mill, difficulty of overhauling of equipment and the like are solved radically.

Description

technical field [0001] The invention relates to a vertical roller mill, in particular to a vertical roller mill suitable for grinding various materials in steel slag, slag, cement, metal ore, non-metal ore, metallurgy, chemical industry and other industries. Background technique [0002] Steel slag has a complex structure, which is a combination of iron and its oxides and slag, which are mixed with each other, and are very irregular and uneven. Due to the complexity of the steel slag structure, after the steel slag needs to be crushed to a certain fineness, the iron in the steel slag will be enriched in the mill, resulting in a decrease in mill efficiency and an increase in energy consumption. If the mill is not regularly shut down for cleaning, the iron in the mill will Crystal or free iron will cause "over-iron" problems, and even damage the mill, which results in poor continuity of mill work; wearing parts have short life, frequent replacement, and high operating cost...
