Description

Изобретение касаетс обогащени полезных ископаемых и может быть использовано в горной, химической и стрюительной отрасл х промышленности.The invention relates to the enrichment of minerals and can be used in the mining, chemical, and destructive industries.

Известна конусна дробилка с эксцентриковым приводом и с верхней точкой гирации внутреннего подвижного конуса l .The known cone crusher with an eccentric drive and with an upper gyration point of the internal rolling cone l.

В верхней зоне камеры дроблени , образуемой неподвижным наружным конусом , ход последнего недостаточен дл создани разрушающих деформаций в кусках крупных размеров, а-в нижней зоне - очень велик.In the upper zone of the crushing chamber formed by a fixed external cone, the stroke of the latter is insufficient to create destructive deformations in pieces of large size, and in the lower zone is very large.

По технической сущности наиболее близкой к предлагаемой дробилке вл етс конусна инерционна дробилка , содержаща корпус с наружным конусом и сферической опорой дл внутpetjH .ero конуса, вал которого снабжен , дебалансчым вибратором 2 .The technical essence closest to the crusher is a cone inertial crusher comprising a housing with an outer cone and a spherical support for the inner AH con a shaft whose shaft is equipped with an unbalanced vibrator 2.

Инерционна конусна дробилка также вл етс динамически уравновешенной машиной, что позвол ет использовать в ней высокие скоростные режимы. Производительность инерционной конусной дробилки выше, чем гирационной дробилки.Inertial cone crusher is also a dynamically balanced machine, which allows it to use high speed modes. The performance of the inertial cone crusher is higher than that of the gyratory crusher.

Однако дроб щие тела этой машины,, выполненные в виде усеченных конусов.However, the crushing bodies of this machine, made in the form of truncated cones.

не позвол ют принимать достаточно крупные куски руды, что обусловливает пониженную степень дроблени .It is not possible to accept rather large pieces of ore, which results in a reduced degree of crushing.

Целью изобретени вл етс повышение степени дроблени .The aim of the invention is to increase the degree of fragmentation.

Цель достигаетс , тем, что в конусной инерционной дробилке, содержащей корпус с наружным конусом и сферической опорой дл внутреннего конуса, The goal is achieved by the fact that in a cone inertial crusher comprising a body with an outer cone and a spherical support for the inner cone,

10 вал которого снабжен дебалансным вибратором , наружный и внутренний конусы выполнены в виде усеченных пирамид, а сферическа опора .- в виде муфты Ольдгема.10 whose shaft is equipped with an unbalance vibrator, the outer and inner cones are made in the form of truncated pyramids, and the spherical support. In the form of the Oldhem coupling.

Выполнение сферической опоры в виде крестовой муфты Ольдгема обеспе 1ивает возвратно-поступательное и смещающее перемшценне внутренней . пирамиды относительно наружной. По20 добное конструктивное решение сферической опоры преобразует вращательное движение дебаланса в возвратнопоступательное перемещение пирамиды внутреннего конуса при одновременном The execution of the spherical support in the form of a cross coupling Oldgem provides a reciprocating and displacing alternating internal. pyramid relatively outdoor. A similar design solution of the spherical support transforms the rotational motion of the unbalance into a reciprocating movement of the pyramid of the inner cone, while

thirty . a high degree of crushing. In addition, it increases the path traveled by the crushing material in the crushing cavity due to the movement of the inner pyramid across the faces of the fixed pyramid. Under these conditions, the piece of material is subjected to almost 1.5 times more clamping, which also leads to a high degree of contraction. Thus, it has a displacing effect on the material being crushed, the crusher being proposed captures almost one and a half times a larger piece than the known cone inertial crusher. FIG. i schematically shows a cone inertial crusher, a section; in fig. 2 is a view A of FIG. one; in fig. -3 depicted in perspective view of the internally truncated pyramid. and spherical support in a dismembered form. the crusher contains i with an outer cone 2 and a spherical support 3 for the inner cone 4. In this case, the cones 2 and 4 are made in the form of truncated pyramids, the cone 4 is equipped with a shaft 5 on which the unbalance vibrator 6 is mounted. Vibrate 6 is connected through the elastic coupling 7 with the pulley 8 of the V-belt drive of the crusher, the housing 1 of the crusher and is supported through the soft springs 9 on the ground 10. The crusher works as follows. The original material enters the straight hole of the cone 2, made in the form of a truncated pyramid. During the rotation of the vibrator b, the disturbing force is transmitted to the cone 4, made in the form of a truncated pyramid, together with it moving along the slots of the support 3. As the grooves are mutually perpendicular to the X-runes truncated tsiramid have one. temporarily reciprocating transverse transverse displacements of truncated pyramids relative to each other. As the faces approach and their lateral displacement, the ore is crushed and the lateral indentation of its pieces along the jan, which leads to an increase in the number of material holdings, and, consequently, to an increase in the degree of crushing. At the same time, from the opposite side, the truncated pyramids move away from one another and the crushed product is unloaded. Accordingly, between perpendicularly arranged faces, on the one hand, the material is compacted and compressed, and on the other hand, the material is released and starts unloading. Since the proposed crusher can adopt a larger piece and carry out the crushing of ore with a high degree of reduction, it is advisable to use it instead of crushers of medium and fine crushing. In a factory with a capacity of 10 million tons of ore per year, the use of a conical vibratory crusher will give an economic effect of 500 thousand rubles. on one crusher. The invention The cone inertial crusher, comprising a housing with an outer cone and a spherical support for the inner cone, the shaft of which is equipped with an unbalance vibrator, is made in such a way that, in order to increase the degree of dredging, the outer and inner cones are made in the form truncated pyramids, and spherical support in the form of Oldhem coupling.
