Definitions

  • the invention relates to a drive train for a roll crusher and a roll crusher comprising such a drive train, wherein the crushers are useful as crushing machines for minerals in the mining industry.
  • roll crushers There are various types of roll crushers that are a subgroup of sizers known. A distinction is made between the number of rollers and the type of drive of the rollers. Often double roll crushers with two crushing rollers are used. These have a one-sided drive, i. only one roller is driven or a two-sided drive. By synchronizing the two crusher shafts both can be driven by a one-sided drive. In the powertrain, a transmission is usually provided between the engine and the crusher. Such a crusher is presented for example in WO 2010/032037 A. A disadvantage is in addition to the large space required for such a crusher and the high cost of alignment of the drive train.
  • Direct drive means here that the driving force is transmitted via shafts and possibly also transmissions or couplings.
  • roll crushers are known in which the motors are arranged axially parallel to the crushing rollers next to the crusher and the power is transmitted to the crushing rollers by means of belt drive.
  • the axis of one of the crushing rollers is designed to be displaceable parallel to the axial direction, whereby an overload protection and adjustability of the crushing gap is ensured.
  • An example of such crushers is presented in the brochure "C800 series hybrid" from the company Sandvik from 2010.
  • a disadvantage is the slip resulting from the belt drive, which makes a defined pressure angle of the two crushing rollers impossible to each other and also a continuous grain size by the magnification
  • the belt drive requires increased safety due to the large belt pulleys, must be protected from flying mineral breakage and is also expensive to maintain.
  • Object of the present invention is therefore to propose a drive train for a roll crusher, which allows a compact design of the roll crusher.
  • the crusher should also be easy to set up and assemble.
  • the drive train according to the invention for a roll crusher has at least one transmission and one motor, the motor directly driving the drive shaft of the transmission and the output shaft of the transmission directly driving the roll crusher.
  • Direct drive means in the context of this document, that the power transmission is slip-free, not via a belt drive or the like.
  • the transmission is designed such that the input and output shafts are located on the same side of the transmission and therefore the engine and roll crushers are also arranged on the same side of the transmission.
  • the drive train makes such a turn whereby the total length of a crusher can be significantly reduced.

Abstract

La chaîne cinématique selon l'invention destinée à un broyeur à rouleaux comprend au moins une transmission et un moteur. Le moteur entraîne directement l'arbre d'entraînement de la transmission, l'arbre de sortie de la transmission entraîne directement le broyeur à rouleaux. Entraîné directement signifie dans le contexte de la présente invention que la transmission de la force est effectuée sans glissement, en d'autres termes qu'elle n'est pas effectuée par l'intermédiaire d'un système d'entraînement par courroie ou similaire. Selon l'invention, la transmission est configurée de telle manière que l'arbre d'entraînement et l'arbre de sortie se trouvent sur le même côté de la transmission, et donc que le moteur et le broyeur à rouleaux sont disposés également sur le même côté de transmission. La chaîne cinématique effectue de manière avantageuse un tour tel que la longueur totale d'un broyeur s'en trouve considérablement réduite. Un arbre à cardan est disposé de manière particulièrement préférée entre le moteur et la transmission ou entre la transmission et le broyeur à rouleaux. Ainsi, le moteur ou le broyeur peuvent être disposés avantageusement de manière décalée par rapport à la transmission, et le broyeur peut être réalisé de manière à présenter de plus petites dimensions. De plus, le recours à des moyens servant à aligner l'arbre de moteur ou l'arbre du cylindre de broyeur par rapport à l'arbre à cardan concerné est de manière avantageuse inutile.
