The purpose of this utility model is to realize like this, comprise that pan feeding scraper-trough conveyer, bulk cargo dish, deflector chute, wind wheel, sieve plate, coarse fodder cone, fines cone, fines enter to grind scraper-trough conveyer, return roll squeezer coarse fodder scraper-trough conveyer, pull bar, material inlet, described bulk cargo dish top arranges pan feeding scraper-trough conveyer, and below sets gradually deflector chute, wind wheel; Coarse fodder cone is set under described wind wheel, and coarse fodder cone bottom arranges back roll squeezer coarse fodder scraper-trough conveyer; Described coarse fodder cone periphery arranges fines cone, and described fines cone bottom arranges fines and enters to grind scraper-trough conveyer, between described coarse fodder cone and fines cone, pull bar is set; Between described coarse fodder cone and fines cone, sieve plate is set.
The utility model increases by a circle sieve plate between coarse fodder cone and fines cone, coarse grained material is entered into after fine powder is bored and again sieve, and reduce the granule content of mill feed material, and the largest particles is less than 5 millimeters.Effectively solved the large particulate material of part and easily dropped in fines cone, grinding machine grinding is impacted, particulate material is crossed in the mill that results in blockage at most and is combed and stitch, and produces full mill, by the problem of forced-stopping machine cleaning comb seam.The utility model is simple in structure, cheap, reliable, can effectively reduce the generation of feed blocking.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is that sieve plate is arranged schematic top plan view;
In figure: 1-pan feeding scraper-trough conveyer, 2-bulk cargo dish, 3-deflector chute, 4-wind wheel, 5-sieve plate, 6-coarse fodder cone, 7-expects cone, and 8-fines enters to grind scraper-trough conveyer, and 9-returns roll squeezer coarse fodder scraper-trough conveyer, 10-pull bar, 11-material inlet.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but never in any form the utility model is limited, any conversion or the improvement based on the utility model training centre, done, all fall into protection domain of the present utility model.
As shown in Figure 1 and 2, the utility model comprises that pan feeding scraper-trough conveyer 1, bulk cargo dish 2, deflector chute 3, wind wheel 4, sieve plate 5, coarse fodder cone 6, fines cone 7, fines enter to grind scraper-trough conveyer 8, return roll squeezer coarse fodder scraper-trough conveyer 9, pull bar 10, material inlet 11, described bulk cargo dish 2 tops arrange pan feeding scraper-trough conveyer 1, and below sets gradually deflector chute 3, wind wheel 4; Coarse fodder cone 6 is set under described wind wheel 4, and coarse fodder is bored 6 bottoms roll squeezer coarse fodder scraper-trough conveyer 9 is set back; Described coarse fodder is bored 6 peripheries fines cone 7 is set, and described fines is bored 7 bottoms and fines is set is entered to grind scraper-trough conveyer 8, and described coarse fodder cone 6 arranges pull bar 10 between boring 7 with fines; Between described coarse fodder cone 6 and fines cone 7, sieve plate 5 is set.
The hypomere of described sieve plate 5 arranges edge on coarse fodder cone 6.
Described sieve plate 5 is the cone of acute triangle for longitudinal profile, and its hypotenuse is conical screen cloth face, and its minor face is bracing frame, relies on pull bar 10 and vertically arranges.
At the bottom of the cone of described sieve plate 5, bore 6 affixedly with coarse fodder, bracing frame and fines are bored between 7 walls the working clearance are set.
