Abstract
The horizontal centrifugal roller mill of the utility model is a thick cylinder supported by a slipper group and a riding wheel group. The inner surface of the cylinder is in the shape of a round table. The big end of the cylinder is a discharge end, and the small end of the cylinder is a feed end. Both ends of the cylinder are provided with sealing covers, and the inner part of the cylinder is provided with a pressure roll shaft. The center of the pressure roll shaft is not at the center vertical line of the cylinder, and the pressure roll shaft is fixed with a centrifugal sphere roller. The cylinder outer part of the feed end is provided with a gear ring connected with a drive mechanism and making the cylinder rotate. The utility model combines the advantages of a centrifugal medium mill and of a cylinder roller mill, and makes materials respectively realize two processes of extrusion pulverization and centrifugal milling. The horizontal centrifugal roller mill increases milling efficiency, improves production quality, reduces inner liner wearing, particularly makes full use of useful space in the cylinder, and enhances equipment investment utilization rate.
Description
The utility model relates to a kind of grinding device, a kind of specifically horizontal Centrifugal rolling grinding mill.
Reducing rotating cylinder collars grinding machine (patent No. 9724919, X, the applying date 970610) disclose a kind of by supporting of crawler shoe group or support roller group and the reducing cylindrical shell that rotated by transmission mechanism, built-in pressure roller shaft of cylindrical shell and empty being enclosed within rolling that ring forms on the roll shaft, mineral such as lime stone, clinker are carried out the equipment of grinding, problem such as be used for solving existing milling equipment energy consumption height, iron loss height commonly used, grinding effect is not good enough.Owing to adopted the reducing cylindrical shell, rolling of curve section configuration encircles and cylinder inboard wall curve liner plate, can realize the classification pulverizing, improve granule-morphology, and adopt the roll shaft biasing, guarantee material is effectively pulverized, reduced and rolled the ring and the moment of resistance that roll shaft is subjected to, improved equipment life and capacity usage ratio.
The purpose of this utility model is to provide a kind of material that makes to be implemented in circulation in the grinding machine, reduces the liner wearing and tearing, further strengthens classifying capability, improves mill efficiency, improves the horizontal Centrifugal rolling grinding mill of powder product microscopic appearance.
The purpose of this utility model realizes in the following manner: a kind of horizontal Centrifugal rolling grinding mill, be a kind of by crawler shoe group or support roller group supporting thick-wall cylinder, cylinder inner surface is a truncated cone-shaped, the big end of cylindrical shell is a discharge end, small end is a feed end, the cylindrical shell two ends are provided with end cover, there is a pressure roller inside of cylindrical shell, the center of this pressure roller is not on the vertical line of crossing the cylindrical shell center, be installed with centrifugal sphere roller on the described pressure roller, a gear ring that links to each other and cylindrical shell is rotated with transmission mechanism cylindrical shell outside is housed in the cylindrical shell outside of material end.
Feed end one side is equipped with the scraper cutter in the cylindrical shell.Centrifugal sphere roller at ring support radially to move freely along annulus on the support.The cylindrical shell discharge end covers a blast pipe in addition.
The utility model revolves cylindrical shell with reducing to be compared, and is to have replaced the ring that rolls of empty cover with the centrifugal anchor ring roller that is fixedly mounted on the pressure roller, thereby centrifugal medium grinding and bed of material extruding grinding are combined in the machine, has further improved energy utilization ratio; Centrifugal sphere roller is to rely on centrifugal force to roll material on the cylinder inboard wall, therefore, the variation of thickness of feed layer is had better self-adjusting than the rolling ring that reducing revolves in the collars grinding machine, and reduced the wearing and tearing to liner.In a word, the utility model combines the advantage of centrifugal medium grinding machine and cylindrical-roll grinder, the flow direction by the grinding charge material makes material realize extruding pulverizing and centrifugal two processes of milling successively, improved mill efficiency, improved product quality, especially make full use of the useful space in the cylindrical shell, improved the utilization rate of equipment investment.
The utility model content is described in detail in detail with reference to the accompanying drawings.
Fig. 1 is the utility model structural representation
Fig. 2 is the left view of Fig. 1
With reference to accompanying drawing, a level is installed in and is the heavy wall hollow cylinder 9 in crawler shoe group or 11 supportings of support roller group, and cylindrical shell 9 inner surfaces are truncated cone-shaped, and the big end of cylindrical shell is a discharge end, and 6 is discharging opening; Small end is a feed end, 2 is feed hopper, cylindrical shell 9 two ends are provided with end cover 3, there is a pressure roller 8 inside of cylindrical shell, the center of this pressure roller 8 is not on the vertical line of crossing cylindrical shell 9 centers, be installed with centrifugal sphere roller 7 on the described pressure roller 8, centrifugal sphere roller 7 can radially move freely along the annulus on the support 13 on the ring support 13.Be equipped with one links to each other with transmission mechanism 12 outside the cylindrical shell and makes the gear ring 10 of cylindrical shell 9 rotations in cylindrical shell 9 outsides of feed end.Feed end one side is equipped with scraper cutter 1 in the cylindrical shell 9.Cylindrical shell also is equipped with device for exerting 4 outward.Cylindrical shell 9 discharge ends cover a blast pipe 5 in addition.During work, after material enters cylindrical shell 9 from feed hopper 2, in cylindrical shell 9, will form the bed of material, place the pressure roll 8 in the cylindrical shell under the effect of device for exerting 4, to press to material and material is pulverized, because the effect of friction, rotary cylinder body can be rotated in the same way by the material bed pressure roller 8 that makes, material is after territory, quilt are pulverized between the pressure area between pressure roller and the cylinder inboard wall, under centrifugal action, be attached to rotation together on the cylinder inboard wall, and under the work of scraper cutter, be pushed to discharge end, circulate successively until the centrifugal district that mills.In the centrifugal district that mills, initial material particle diameter after the repeatedly circulation crushing of leading portion diminishes, the nature stacking volume increases, but the strain of cylinder internal diameter phase is big, can make bed of material attenuation, and mill down the centrifugal of centrifugal sphere roller 7 of high speed rotating, the material particles quilt is further levigate and make the shape of particulate progressively become sphere, flow out from hopper 6 again, thereby finish whole grinding flow process.The fixing seal end cap 3 at cylindrical shell 9 two ends plays protective action, and thermal current enters dust-precipitator through blast pipe 5 in the mill, and makes the little negative pressure of formation in the mill, prevents that dust from escaping.
