Definitions

  • the invention relates to a comb tooth holder, in particular for crushing devices with cutting teeth provided on crushing rollers, which cooperate with at least one counter-holder or basket comb teeth for crushing the material to be comminuted, consisting of at least one Camrntechnik analyses and at least one comb tooth, wherein the comb tooth by means of a first positive connection attachable to the comb tooth body.
  • the invention also relates to a comminution device or comminution machine with such a comb tooth holder.
  • Such comb tooth holders are known in the art. They are used in crushers or machines that serve a wide variety of shredding tasks. Especially in the field of waste crushers these devices are used. Due to the different material to be shredded and the requirements are particularly different to the crushing tools, such as knives or teeth, so that often a change is necessary if other material must be crushed. Also, the crushing tools are exposed to high wear, so that a frequent change is necessary for this reason. This also applies in particular to the teeth which are arranged on a counterhold or baskets of the comminution device. These interact with knives or teeth which are arranged on a crushing roller. They are referred to below as comb teeth. The necessary change of the comb teeth due to wear or conversion of the crushed material is very time consuming and causes thereby high costs. The teeth provided as wear parts are also quite expensive due to the relatively high proportion of material.
  • a knife body is known in the art, which is characterized by a positive arrangement of the knife on a knife or tooth body.
  • This blade carrier is provided for the arrangement on a crushing roller of the device.
  • the proportion of material of the knife in the total material used for measuring knives and knife body is quite high.
