Description

II

Изобретение относитс к устройствам дл измельчени материала и может быть применено в строительной, горнорудной и других отрасл х промышленности .The invention relates to a device for grinding material and can be applied in the construction, mining and other industries.

Известно устройство дл дроблени , содержащее дроб щее приспособление,A device for crushing is known, which contains a crushing device,

г выполненное в виде зубчатых валков, установленных под решеткой, разгрузочную решетку V-образной формы. Недостатком такого устройства вл етс низка эффективность измельчени вследствие наличи в них мертвой зоны, где скапливаетс необработанный материал, а также ввиду налипани материала на решетку при обработке влажного сырь J.g made in the form of toothed rolls installed under the grating, the discharge grating is V-shaped. The disadvantage of this device is the low grinding efficiency due to the presence of a dead zone in them, where the raw material accumulates, as well as due to the material sticking to the grate when processing wet raw material J.

,техническим решением из известных вл етс устройство дл измельчени материала, содержащее дроб щее приспособление , выполненное в виде зубчатых валков, взаимодействующих с, a technical solution of the known is a device for grinding material, containing a crushing device made in the form of toothed rolls, interacting with

решеткой, набранной из элементов, закрепленных на корпусе.grille, recruited from the elements attached to the housing.

Однако решетка, выполненна с отверсти ми дл прохода зубьев на - одной ее стороне, расположенными против отверстий на другой стороне, не позвол ет размещать зубь вращающихс один навстречу другому валков без зазора между их концами.However, a grid made with holes for the passage of teeth on its one side, located opposite the holes on the other side, does not allow to place the teeth rotating one towards the other rolls without a gap between their ends.

IQ Наличие указанного «зазора приводит к образованию в центре решетки между зубь Ми валков мертвой зоны и к снижению эффективности измельчени , кроме того, выполнение реfj шетки V-образной формы, при которой она вл етс опорой дл всей массы обрабатываемого материала, приводит к созданию ею дополнительного сопротивлени , на преодоление которого требуютс значительные энергозатраты t2j.IQ The presence of this "gap leads to the formation of a dead zone in the center of the lattice between the teeth of Mie and to a reduction in the efficiency of grinding, moreover, the execution of the refj of the V-shaped grid, in which it is a support for the whole mass of the material being processed, leads to its creation additional resistance, overcoming of which requires significant energy consumption t2j.

Claims

The purpose of the invention is to increase the grinding efficiency and reduce the power consumption of the devices. 3 This goal is achieved by the fact that in a device for shredding cup material containing a crushing device made in de gearing rolls interacting with a grid made up of elements fixed to the body, the grid is sectional, each section of the grid being mounted between the wall of the housing and the roller of the crushing device, and the sections are displaced one relative to another in the horizontal plane by the width of the lattice element. In FIG. 1 shows the proposed grinding device, general view; FIG. 2 is a section A-A in FIG. 1. FIG. A device for grinding a piece of material consists of a body in which, under separate sections of the grid 2, inclined towards each other, there are rollers 3 equipped with teeth 4. In the intersectional space, the teeth t of one roller are placed in the groove between the teeth 4 of the other roller. The ends of the plates 5, of which the sections of the lattice 2 are composed, shifted one relative to the other by the width of one plate, are hinged in the walls of the housing 1, the grooves 6 are made in the walls of the housing 1 in place of the installation of the plates 5, which in other embodiments can be made as rods or grates of various shapes. The eccentrics 7 are fixed on the same axis with the rolls 3 and the rollers 8 are mounted on the extreme plates 5 of the grid 2. The device works as follows. The material in the form of lumps is served. In case 1, the sections of the grids 2 and in the intersectional space on the bearing surface formed by the teeth k of one roll, placed between the teeth of the other roll, are ground by rotating towards each other the teeth passing through the grid 2. The eccentric driven from the rolls 3 to 7, acting on the roller 8, lifts the grid 2, which at the next time point when the roller leaves the gearing with the eccentric sharply lowers the sticking material. The upper part of the hinged end of the plate 5 rests when the lattice 2 is lowered onto the wall in the groove 6, preventing the plate 5 from rotating around the hinge. The roller B is made of elastic material, for example rubber, which reduces the noise level. The use of the invention makes it possible to increase the grinding efficiency as well as reduce the power consumption of the device. Apparatus of the Invention A device for grinding material comprising a crushing device made in the form of toothed rolls interacting with a grid composed of elements mounted on a housing, characterized in that, in order to increase the efficiency of grinding and reduce the energy intensity of the device, the grid is sectional, and each lattice section is installed between the wall of the housing and the roller of the crushing device, and the sections are displaced relative to each other in the horizontal plane by the width of the element yokes.
