The invention discloses a tooth roller and a grate of a single-tooth roller
crusher for crushing sinter cakes, belonging to the field of initial material
processing in
metal smelting industry. The invention is characterized in that: the tooth roller is produced by inlaying 5-14 crushing toothed rings in a tooth roller that can be available for inlay, the grate is produced by surfacing a grate basic body or conducting secondary
casting to form a layer of wear-resisting
alloy, wherein the crushing toothed rings comprises 3-4 hocks which are mutually occluded and arranged together in order, a layer of the wear-resisting
alloy is formed by surfacing or carrying out secondary
casting on the crown and periphery of the hock, the grate basic body is produced by sealing a cast steel groove-shaped body, a water-stop sheet and a sealing cover by
welding, and the crushing toothed rings, tooth roller and grate basic body are all can be prepared into a
water cooling structure and a half-
water cooling structure. According to the invention, the tooth roller and the grate of the full
water cooling single-tooth roller
crusher have excellent
heat resistance and
wear resistance because of large flow area and good
cooling effect, the
processing technology of the hock, the tooth roller and the grate is simple, the replacement is convenient, the cost of
processing and maintenance is reduced, and the hock and the grate has good repairability.
