  • the problem of transporting the excavated old materials and bringing the newly introduced new materials into circulation has proved to be a limiting factor for this targeted fast track remediation.
  • ballast treatment technique For the area of the ballast bed, a treatment technique has proven to be advantageous in some cases, in which the excavated old ballast is subjected to a treatment in the form of ballast refraction and thus sharpening of the old ballast. From this ballast treatment, at least a portion of the excavated old ballast can be recovered in such a way that it can be used as a new ballot and consequently the volumes of the old ballast to be removed and the approaching new ballast be partially reduced.
  • the present invention is basically concerned with the task of providing a device and a method which enables a more efficient track route rehabilitation.
  • EP2428612A1 For example, a track reclaiming apparatus and method is known in which excavated PSS material is sifted and crushed and thereafter mixed with a binder and water in a mixer. The thus prepared PSS material is then again introduced as a load-bearing layer in the track bed.
  • an increase in the quality of the processed material can be achieved only with a significant wear of the treatment plants on the track construction train, in particular the mixer and the crusher require significantly reduced maintenance intervals when operating the known equipment to achieve increased quality of the recycled material.
  • Such shortened maintenance intervals are not desirable, however, both because of the associated downtime of the entire track bed rehabilitation machine as well as the material required for this purpose, and ultimately a rapid track bed rehabilitation counterproductive.
  • the invention is based on the object to provide an apparatus and a method for a faster track rehabilitation than is possible with the known machines and methods, without thereby reducing the efficiency of the device or the method.
  • the first PSS processing unit further comprises a second screening device for separating coarse fractions and fines, a fractional conveying device for conveying the fractions from the crusher to the second screening device, and a return conveyor for Returning the screened in the second screening coarse components in the crusher.
  • the solution according to the invention is based on an analysis of the problems of existing processing methods and machines. From this it has been found that with the methods which are known from the prior art, although in certain cases a qualitatively sufficient level protective layer can be achieved by the treatment mechanisms and laying techniques taught there, this can not be achieved over the entire length of a track track or for all Soil types is ensured. As a problem that leads to this deficit, it was identified that the quality of the excavated material over the length of a track path and in particular from site to site usually changed significantly.
  • the track remoulding machine which is to be understood here in particular as a track-based track reconditioning machine, comprises two excavating devices, namely an excavating device for gravel lying in front in the working direction and an excavating device for the old PSS lying behind in the working direction, this second excavating device also being used for excavating in the previously explained manner is formed by existing in place of a PSS soil.

Only grains having a grain size below the predetermined grain size dimension are allowed to pass through the second screening device and are directed to the second processing unit.
  • This re-screening and return into the crusher makes it possible to use a crusher which has a crusher characteristic which is adjusted so that broken or unbroken grains emerge from the crusher which are above the desired grain size.
