Description
Affiliated technical field
The utility model relates to a kind of grinding device, particularly a kind ofly selects dressing sieve branch combined type cement grinding mill in the cement production process.
Background technology
Existing in cement production process employed cement grinding mill contain cylindrical shell.The interior front portion of cylindrical shell is ball storehouse I and ball storehouse II, between ball storehouse I and ball storehouse II, be provided with partition panel, the interior rear portion of cylindrical shell is provided with screening plant for forging the storehouse between ball storehouse II and the forging storehouse, and screening plant is usually by grate plate, tubular sieve, meal burden-guiding cone, fine powder burden-guiding cone, ring pipe, the dull and stereotyped composition.The side face of ring pipe is provided with the hole that matches with tubular sieve, one end of this hole and tubular sieve links and the other end of tubular sieve is arranged on the cylinder inboard wall, one end of ring pipe is arranged in the dull and stereotyped endoporus, meal burden-guiding cone and fine powder burden-guiding cone are arranged in the other end of ring pipe, and a side of tubular sieve is arranged on the flat board.In cement production process, tubular sieve is along with the rotation of cylindrical shell, after material web played certain altitude, under the effect of self gravitation, from the compass screen surface of tubular sieve, slide to the coarse fodder burden-guiding cone from top to bottom, meal on the compass screen surface imports cracking cabin by burden-guiding cone and carries out fragmentation, and the fine powder that falls from the sieve aperture of compass screen surface is ground by fine powder burden-guiding cone importing grinding storehouse.Because tubular sieve plays material web in the process of certain altitude, what be taken up is positioned near the compass screen surface outer end edges material, often directly slips into cracking cabin from the compass screen surface outer end edges without sorting, has therefore both had the grinding phenomenon, influences the output of grinding machine again.Because tubular sieve is arranged on the flat board, ventilation is smooth, material flow is slow simultaneously.
The utility model content
The technical problems to be solved in the utility model provides selects dressing sieve branch combined type cement grinding mill in a kind of, not only flowing resistance is little in cement production process for it, material flow fast, screening fully, and reduced the generation of grinding phenomenon.
For solving the problems of the technologies described above, the utility model contains cylindrical shell, interior screening plant, interior screening plant comprises grate plate, the meal burden-guiding cone, tubular sieve, the fine powder burden-guiding cone, ring pipe, tubular sieve one end is arranged on the ring pipe side face and with this pipe and communicates, the other end of tubular sieve is arranged on the cylinder inboard wall, ring pipe is provided with meal burden-guiding cone and fine powder burden-guiding cone at this end, also comprise sieve plate, the ventilation grate plate, the backgauge swash plate, the ventilation grate plate is arranged on the other end of ring pipe, sieve plate is arranged between tubular sieve and the ventilation grate plate, and a side of tubular sieve is arranged on the sieve plate, and the backgauge swash plate is arranged on the compass screen surface outer end edges of tubular sieve.
The formed angle of the compass screen surface of backgauge swash plate and tubular sieve is 45 ° to 65 °.
Owing on the compass screen surface outer end edges of tubular sieve, be provided with the backgauge swash plate, tubular sieve takes up be arranged near the compass screen surface outer end edges material at uphill process, be forced through compass screen surface and screen, thereby screening fully, significantly reduced the generation of grinding phenomenon.Because tubular sieve is arranged on the sieve plate, and the back of sieve plate is provided with the ventilation grate plate, and the material that grinds in the storehouse can not stop up sieve plate and influence mill inner ventilation, so the mill inner ventilation resistance is little, material flow is fast.
