Description
The utility model belongs to the mining machinery field, directly applies to the fragmentation of various ores, rock, gangue.
Current in the fragmentation of mine rock material, the main equipment of using has the jaw crusher and the hammer mill of various models.In processing stone materials, producer generally all is used in combination jaw crusher with hammer mill, jaw crusher is mainly used in the oversize rock material (fragmentation of 100mm~350mm), hammer mill is mainly used in (40mm~100mm) broken again, the building stones stock size after the fragmentation is 15mm~35mm once more from the medium-sized building stones of jaw crushing.Also have and adopt jaw formula or the direct primary fragmentation of hammer mill, charging size so generally all is restricted, and production efficiency is not high.If the hammer mill of 30 kilowatts of jaw crushers and 18.5 kilowatts is used, also need be equipped with 5.5 kilowatts dust catcher, total output will reach 54 kilowatts like this, and its production capacity is 12~15 tons/hour.By retrieval, also there is not to find directly the above building stones of 700mm directly to be broken into the equipment of 15mm~35mm building stones at present.
The purpose of this utility model be exactly to provide a kind of can primary fragmentation big dimension stone to the equipment of 15mm~35mm, it can solve effectively that existing equipment needs the jaw formula connect with hammer to use and need the installation dust catcher and the big drawback of equipment complexity, consumed power that exists.
The purpose of this utility model is to realize like this, body upper is a charging aperture, the middle part is a main spindle box, the bottom is a discharging opening, main spindle box is equipped with main shaft, rotor disk is housed on the main shaft, main shaft stretches out the two ends of body and locates to be equipped with flywheel, the string axle parallel with main shaft is housed on the rotor disk, on the string axle the centrifugal hammer that gets rid of is housed, grate is equipped with at the place at the organism bottom discharging opening, the charging aperture axis of body upper is horizontally disposed and is space crossed vertical with main-shaft axis, the connection place level of charging aperture and main spindle box is evenly equipped with supporting lever in body, the grate of organism bottom extends to charging aperture to the front upper place, extend to more than the supporting lever to the back upper place, main shaft two ends flywheel is provided with the assembly technology hole.The charging aperture that axis horizontal is arranged is provided with the protection steel chain, the supporting lever of the uniform setting of level and charging aperture axis are arranged in parallel, the grate of organism bottom is not less than 70mm to front upper place, the part of back upper place extension and the distance between the forward and backward housing, organism bottom grate rib size is not less than 40mm, and the center, assembly technology hole on the flywheel of main shaft two ends remains on same garden on week with string axle center.
The utility model and existing jaw crusher, hammer mill series connection add the dust catcher mode compares, and has (unit get final product) simple in structure, cost is low, discharging waste gas is few, advantage such as more than the building stones of unit power output.30 kilowatts of hammer mills of employing the utility model manufacturing are used for the exploitation of building stones, per hour go out building stones 54-63 ton, and adopt 30 kilowatts jaw crusher after increasing the dust catcher of 18.5 kilowatts hammer mill and 5.5 kilowatts, per hour go out the same specification building stones and can only reach 12~15 tons.The utility model is compared with simple employing jaw formula and hammer mill, has big, the productivity ratio advantages of higher of charging size, and the charging size can reach more than the 700mm, and general ore does not need preprocessing can directly send into hammer crushing machine inlet capable of the present utility model.The simple maximum 350mm of jaw crusher charging size that adopts 30 kilowatts, production capacity is 14~36 tons/hour, and the discharging size is still between 40~100mm.
Below in conjunction with accompanying drawing foundation hammer mill described in the utility model is described further.
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is a supporting lever floor plan described in the utility model, and Fig. 3 is the rotor disk structural representation.
In Fig. 1, charging aperture is (2), and charging aperture protection chain is (6), the charging aperture center line is (3), and the charging aperture lower edge is (8), and supporting lever is (5), grate is (1), and discharging opening is (15), and main shaft is (12), rotor disk is (13), and the string axle is (10), gets rid of hammer and is (4), flywheel is (7), flywheel assembly technology hole is (9), and preceding discharge road is (11), and back discharge road is (14).
The hammer mill embodiment and the course of work thereof according to the utility model design are as follows: ore protects chain (6) feeding charging aperture (2) through charging aperture, charging aperture (2) is designed and sized to 700 * 860mm, directly the raw materials size smaller of feeding directly smashes by getting rid of hammer (4), the supported thick stick of size the greater (5) supports, get rid of hammer (4) simultaneously and impact building stones, treat to fall from supporting lever (5) voluntarily after the building stones fragmentation, hammer (4) repeatedly impacts after grate (1) is discharged from discharge gate (15) through getting rid of in main spindle box.Grate in the utility model (1) is owing to adopted to front upper place, back upper place extended structure, thereby the backplate at the forward and backward side of grate place is omitted, designed grate rib size must not be less than 40mm, be unlikely very fast damage with the impact that guarantees building stones, grate (1) has just had the backplate function concurrently like this.The distance that the design of grate (1), assembling also must be satisfied between front upper place, back upper place extension and front and back housing is not less than 70mm, with discharge road (11), discharge road (14), back before forming, is convenient to the discharge of broken building stones.Back discharge road (14) considers also that in design it has the function in air channel concurrently, and stone flour is blown out under the wind-force effect of air channel, thereby has saved the supporting dust catcher of existing equipment.For ease of discharge, grate is forward, the rear transition position will leave the angle, garden, present embodiment design grate bottom for the concentric radius of main shaft (12) be half garden of 470mm.The grate lattice are of a size of 50 * 50mm square hole in the present embodiment, and in the general design, grate lattice size should not design too smallly, in order to avoid make that the outlet building stones are too little.The flywheel of present embodiment has respectively designed four assembly technology holes (9), the fabrication hole diameter is 60mm, the fabrication hole center remains on same garden on week with string axle (10) center, for make after the wearing and tearing get rid of hammer (4) and string axle (9) change convenient, the fabrication hole diameter is greater than string shaft diameter 40mm, so that the launching of string axle.The supporting lever of present embodiment (5) is the garden steel of four 60mm, and is horizontal in the direction of parallel import axis, is beneficial to the smooth feeding of raw material.Charging aperture protection chain (6) door curtain is arranged by the steel chain of 14 sections 18 * 60 * 80 and is hung on charging aperture (2) and locate to form, prevent broken building stones collapse.Also adopted four string axles in the present embodiment, on the string axle (10) four rotor disks (13) be housed, be equipped with 3 on the every string axle and get rid of hammer, four string axles totally 12 get rid of hammer.During machine works, 600 rev/mins of the speeds of mainshaft, 30 kilowatt motors directly drive the flywheel running by flat belt, thereby drive main shaft work.
