    A roll crusher for crushing lumpy material particularly coal and other minerals comprises a conveyor trough having a trough bottom with a plurality of longitudinally extending laterally spaced chains trained to run over the trough bottom and move through a path from beneath a crushing roller of the roll crusher. The crushing roller is rotatably mounted above the trough bottom and has a rotatable shaft portion with a plurality of radially extending axially spaced and angularly offset striker portions along its length. A plurality of pushers extend laterally between and interconnect adjacent strands so as to form a chain mat type structure of the conveyor which moves along the trough beneath the crusher roll. The chains are spaced laterally apart by spacing comprising a clearance selected to be equal to or less than the maximum grain size to be formed in the material by the crusher. The pushers are longitudinally spaced between adjacent chains and disposed in respect to the crusher rolls as the striking tools rotate through paths bringing the outer ends of the crushing tools between adjacent strands of the chain. The pushers are advantageously made of a height lower than the vertical links of the chains so that they form trough type recesses therebetween. The pusher height is advantageously made substantially equal to half the height of the vertical chain links. The pushers of adjacent strands are staggered preferably by the length of one vertical chain link.

    专利说明:

    The invention relates to crushers for grinding large-sized material, mainly coal, etc. minerals.
    A known crusher for grinding coarse material 5 containing a roller with crushing tools located on it, a crushing plate, a conveyor with chain branches and Cl 3 scrapers connecting them. A disadvantage of the known crusher is that after grinding the coarse material it has different particle sizes , which is associated with sorting and additional costs 15.
    The purpose of the invention is to increase the efficiency of the grinding process.
    This goal is achieved by the fact that in the crusher for grinding coarse-20 lumpy material containing a roll with crushing tools located on it, a crushing plate, a conveyor with chain branches having horizontal and vertical links, 25 and scrapers connecting them, the chain branches of the conveyor are located one from the other at a distance corresponding to the maximum specified value of the particles of material, and crushing tools are located between the chain branches.
    Moreover, the scrapers in the middle part are made with recesses.
    The height of the scrapers is equal to half the height of the vertical chain links.
    The scrapers are offset one relative to the other half the distance between the scrapers of one pair of chain branches.
    In FIG. 1 shows a crusher for grinding lumpy material la, top view; in FIG. 2 - the same, vertical section; in FIG. 3 ~ same side view.
    Crusher for grinding lumpy material 1, such as coal, etc. minerals, has a crushing roller 2 with percussion instruments 3 located on its shaft. Under impact3 976839
    The proposed crusher’s allows you to increase the efficiency of the grinding process * by ensuring grinding to the desired particle size.
    * 3 at a predetermined distance there is a crushing plate formed by a transport chute 4 of a chain conveyor passing through a single-roll crusher 5. The distance 5 of the transport chute 4 from the crushing roller 2 corresponds to the passage height of the material to be crushed 1. The chain conveyor 5 has several generatrix chains mat of chain branches 6 filling the cross section of the transport channel 4 and connected to each other by means of scrapers 7 · These chain branches 6 are located from each other at a distance of A, 15 a mask in the light of which is less than the desired maximum grain size of the material, on the other hand, the chain branches 6 are located in such a way on the relatively circumferential path 20 of the percussion instruments 3 ”that the latter extend in the middle relative to the chain branches and enter between them. The scrapers 7 in the area between the chain branches 6 have a lower height H than the 25 vertical chain links 9, with the formation of recesses 8 or recesses. The height H of the scrapers corresponds to half the height of the vertical chain links 9. To every fourth link of the chain, respectively, to every second horizontal link 10 of the adjacent chain branches 6, a scraper 7 is connected. The scrapers 7 of all chain branches 6 are displaced. relative to one another at half the distance between the fault 35 skrobkami pair of chain branches. In a special form of execution with rubber conveyor belts, the distance A between the chain branches 6 is equal to or less than 200 mm. 40

    3976 tools 3 there is a crushing plate at a given distance, formed by a transport chute D of a chain conveyor 5 passing through a single-roll crusher. the chain mat of the chain branches 6, which fill the cross section of the transport chute k and are connected to each other by means of the scrapers 7. These chain branches 6 are located apart from each other |; and in the distance A, elichina in light which is less than the desired maximum value of the grain material from the other side chain branches 6 are arranged in such a way to the circumferential trajectory drum 3 that extend past the middle of the chain with respect to the input branch and m therebetween. The scrapers 7 in the zone between the chain branches 6 have a lower height H than the vertical chain links 9, with the formation of notches 8 or depressions, the height H of the scrapers corresponds to half the height of the vertical chain links 9. To every fourth link in the chain, respectively to every second horizontal link 10 adjacent chain branches 6, a scraper 7 is connected. Scrapers 7 of all chain branches 6 are offset one half of the distance between the scrapers of a pair of chain branches. In the case of a special embodiment with rubber conveyor belts, the distance L between the chain legs 6 is equal to or less than 200 mm. The proposed crusher allows to increase the economics of the grinding process by providing grinding to the desired particle size. Claim 1. Crusher for grinding lumpy material, containing roller with crushing tools located on it, crushing plate, conveyor with chain branches having horizontal and vertical links, and scrapers connecting them, so that the efficiency of the grinding process, the chain branches of the conveyor are located one from another at a distance corresponding to the maximum specified particle size of the material, and the crushing tools are located between the chain branches.
