Abstract
A crusher combination screen plate, belonging to the crushing and screening technology in the machines fields. The crusher combination screen plate can improve the crushing hammer head efficiency of the crushing machine, reducing the retention time of great hardness and large grained materials in the crusher, improving and optimizing the gradation proportion of the material granularity after crushed. The cambered screen plate adopted the technical proposal, is a combination screen plate, equipping a blocking strip parallel to one or two the crusher rotator axial direction on the inner bottom part of the cambered screen plate, the height of the blocking strip is one third to half of the distance between the hammer head and the screen plate. The crusher combination screen plate is applied to the ring hammer crusher and the hammer crusher.
Description
Technical field
The utility model provides a kind of disintegrating machine Combined sieve board, and it is specially adapted to pulverize and sieve the hammer mill and the ring crusher of ore.Belong to fragmentation and material sieving technology in the mechanical field.
Background technology
In metallurgical mine, chemical building material and energy field, in the material grinding link, a large amount of use disintegrating machines.Though it is a kind of ancient machining equipment, there are shortcomings such as energy consumption is big, efficient is low, because simple and practical, be still basic technology indispensable in this technical field so far.And how to realize the grain size distribution ratio of preferable crushing rear material, effectively the crushing efficiency that strengthens big hardness, large granular materials is a difficult problem that is perplexing the pulverizer technology of interstitial structures such as this tup and circular arc sieve plate always.
Summary of the invention
In order to solve the technical problem that aforesaid hammer mill exists, the invention provides a kind of can improve crusher in crushing tup efficient, reduce hardness big, large granular materials RT in disintegrating machine, improve and optimize the technical scheme of the disintegrating machine Combined sieve board of crushing rear material grain size distribution ratio.
The technical scheme that the invention is adopted is, at the arc screening plate inner bottom part of disintegrating machine, disposes one to two and is parallel to the axial parting bead of crusher rotor, and the height of parting bead is the 1/3-1/2 of tup and sieve plate distance.
In the hammer mill that the disintegrating machine sieve plate of employing the technical program is formed, distance between tup and sieve plate, become the gap between tup and parting bead at the parting bead place, obviously reduce large granular materials and pass through the space, play the effect that stops that large granular materials passes through, when being convenient to tup and forwarding this position to, in this disintegrating machine in the minimum broken gap, cooperate the effect of large granular materials enforcement impact-rolling with parting bead, reach its effectively broken purpose.
Adopt the disintegrating machine of the technical program, for using the more higher coal of dust burdening in the recirculating fluidized bed, perhaps spoil and coal mix in the fragmentation that forms fuel, those dust burdenings are bigger, that is the high large granular materials of hardness has been subjected to broken effectively and reliably, crushing efficiency height not only, and broken back raw meal particle size level mixing ratio also improves, simultaneously in tup and sieve plate gap because wearing and tearing when causing increasing not instant the adjustment, the related sieve plate parting bead of the technical program structure also plays the disintegrating machine output grain diameter restriction that makes a final check.
Description of drawings
Fig. 1 is a disintegrating machine Combined sieve board organigram, and Fig. 2 adopts the utility model technology disintegrating machine structure schematic diagram, and Fig. 3 is a disintegrating machine Combined sieve board parting bead cross sectional representation.
The specific embodiment
One, disintegrating machine Combined sieve board is made of arc screening plate 3 and the parting bead that is parallel to crusher rotor axle 14 that is configured in its inner bottom part.In this specific embodiment, the height of parting bead 4 is 2/5 of tup 2 and sieve plate 3 distances, disposes a parting bead, and this parting bead cross section is an isosceles trapezoid, and the width of cross section is the twice of its height.
Two, the disintegrating machine Combined sieve board is the ellipse except that parting bead 4 cross sections, and other member parameter is all identical with embodiment one.
Three, at the capable sieve plate 3 and being configured in the disintegrating machine sieve plate that the parting bead that is parallel to crusher shaft 14 of its inner bottom part constituted by arc, parting bead 4 is two, and its cross section is an isosceles trapezoid, and the height of cross section is 7/15 of tup 2 and sieve plate 3 distances.
Four, in the present embodiment, except that parting bead 4 cross sections are the half elliptic, other member parameter is all identical with embodiment three.
Five, in the present embodiment, parting bead 4 cross sections are semicircle, and other member parameter is all identical with embodiment three.
Six, in the present embodiment, the cross section of parting bead 4 is a rectangle.Other member parameter is all identical with embodiment one.
In the above-mentioned specific embodiment, parting bead 4 can adopt the inner bottom part that is fixed on arc screening plate such as fixed forms such as welding, bolted, cast setting, jigs.
