Abstract
The utility model relates to a foregrinding machine used before mine and building-material products entering the globe mill, in particular to a novel environment-protecting nondusting hammer breaker. The utility model comprises an upper box body, a lower box body, a rotating shaft, a disc, a spacer sleeve, a hammer link, a hammer, and inner lining boards. The inner lining boards of the inner impact face of the upper box body are formed by arranged tooth-formed convex blocks; the middle part of the impact face of each convex block is provided with a concave groove; the two slopes forming the concave groove become higher from the upper part to the lower part along the motion direction of the hammer; the other inner side of the upper box body corresponding to the impact face is provided with inner lining boards the upper surface of which has teeth; the upper box body and the lower box body form a closed box body; the lower box body is provided with a semi-circular grate plate which forms a crushing cavity together with the upper box body. The foregrinding machine has the advantages of a long period of usage, high production efficiency, and meeting environment-protecting requirements.
Description
Technical field:
The utility model relates to the precomminution machinery before the mine building material product enters ball mill, and particularly a kind of novel environment friendly does not have the dust hammer mill.
Background technology:
Whether the liner structure design of hammer mill is reasonable, directly influence the fragmentation quality and the operating efficiency of disintegrating machine, and because it is a consumable accessory, improving its service life, being convenient for changing is the difficult problem that need solve in the industry; Shell is generally partial closure, and dust is bigger during work, is difficult to reach environmental requirement; Medium-sized sieve plate influences the useful space of crusher chamber, thereby causes the reduction of production capacity.
Summary of the invention:
Goal of the invention of the present utility model is in order to solve a difficult problem described in the background technology, and the novel hammer mill of a kind of long service life, production efficiency height, compliance with environmental protection requirements is provided.
The technical scheme that realizes the foregoing invention purpose is: this disintegrating machine is by lower box, upper box, rotating shaft, disk, spacer sleeve, the tup connecting rod, tup, parts such as interior lining panel are formed, the first-class fixed interval of this rotating shaft has disk, between two disks spacer sleeve is housed, by tup connecting rod movable tup is housed between each disk along its circumference uniform distribution, the interior lining panel of the inboard shock surface of upper box constitutes by being the tooth form projection of arranging shape, its middle part of the shock surface of each projection is provided with groove, form the two domatic of groove, another medial surface of upper box that should shock surface is equipped with the toothed interior lining panel of upper surface along low high on the tup direction of motion; Lower box and upper box constitute enclosed housing, and the semicircle grate plate that constitutes crusher chamber with upper box is housed in the lower box.
Novel hammer mill according to technique scheme enforcement, the tooth form projection lining plate structure of its shock surface is outside one's consideration except that having increased crushing force, also can stop the material that does not reach fineness to return out outside crusher chamber, especially independently monomer projection cube structure is convenient for changing the projection of serious wear at any time; Increase surperficial toothed interior lining panel in the upper box, not only can protect upper box not to be subjected to any impact failure, also increased the broken dynamics of material in crusher chamber simultaneously; Because the rotor high-speed rotation, therefore material need be got rid of outside the crusher chamber, at short notice, adopt the grate plate to replace common sieve plate, can increase the useful space of crusher chamber, prevent to get stuck, help realizing second-time breakage, under the prerequisite that does not influence grate plate operation instruction, improved production capacity.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the axial cut-away view of Fig. 1.
The specific embodiment:
Provide specific embodiment of the utility model below in conjunction with accompanying drawing.The described novel hammer mill of this embodiment is by lower box 1, grate plate 2, tup 3, shock surface liner plate 4, discharging opening, tooth form projection 5, fastening bolt 6, upper box 7, charging chews 8, projection groove 9, toothed interior lining panel 10, belt pulley 11, disk 12, tup connecting rod 13, spacer sleeve 14, bearing assembly 15, rotating shaft 16 parts such as grade are formed, this rotating shaft 16 is installed in lower box 1 upper end by bearing assembly 15, its first-class fixed interval has disk 12, between two disks 12 spacer sleeve 14 is housed, by tup connecting rod 13 movable tup 3 is housed between each disk 12 along its circumference uniform distribution, upper box 7 inboards are equipped with by fastening bolt 6 and are the tooth form projection 5 of arranging shape, this tooth form projection 5 constitutes shock surface liner plate 4, its middle part of the shock surface of each projection 5 is provided with groove 9, form the two domatic of groove 9, upper box 7 another medial surfaces that should shock surface are equipped with the toothed interior lining panel 10 of upper surface along low high on the tup direction of motion; Lower box 1 constitutes enclosed housing with upper box 7, and the semicircle grate plate 2 that constitutes crusher chamber with upper box 7 is housed in the lower box 1.
The operation principle of this novel hammer mill is summarized as follows: the belt pulley 11 on the motor drives rotating shaft 16, make the whole rotor of forming by rotating shaft 16, disk 12, tup connecting rod 13 drive tup 3 high speed counter-rotatings, produce powerful centrifugal force, make the material that is broken in crusher chamber, carry out the mandatory fragmentation in a week nearly, when material during less than grate plate 2 holes, material can be borrowed action of centrifugal force, goes out outside the crusher chamber by the position of design.This machine can adapt to the ore of various compression strength more than 260Mpa, and particle size after cracking is adjustable below 5mm.
