         2 . The Impact reactor according to  claim 1 , wherein the classifying device is a screen. 
     
     
         3 . The impact reactor according to  claim 2 , wherein the screen is roller-shaped. 
     
     
         4 . The impact reactor according to  claim 2 , wherein the screen is arranged to be able to rotate in the suction opening. 
     
     
         5 . The impact reactor according to  claim 1 , wherein the classifying device is formed as an air separator. 
     
     
         6 . The impact reactor according to  claim 5 , wherein the classifying device is formed as a deflection wheel. 
     
     
         7 . The Impact reactor according to  claim 6 , wherein the deflection wheel comprises two mutually spaced apart rotor disks having rotor blades arranged between them. 
     
     
         8 . The impact reactor according to  claim 1 , wherein the classifying device is formed to separate out particles having a pre-selectable particle size. 
     
     
         9 . The impact reactor according to  claim 1 , wherein a cleaning apparatus is assigned to the classifying device. 
     
     
         10 . The impact reactor according to  claim 1 , wherein a supply air opening is placed into the impact reactor. 
     
     
         11 . The impact reactor according to  claim 1 , wherein the casing is closed in the region of the rotor. 
     
     
         12 . A method of processing accumulator batteries in an impact reactor according to  claim 1 , wherein the accumulator batteries are fed to the impact reactor and are comminuted in the impact reactor by means of mechanical loading of the rotor provided with impact elements, wherein the dusty parts of the accumulator batteries are removed from the impact reactor via the suction opening. 
     
     
         13 . The method according to  claim 12 , wherein the accumulator batteries are initially fed to a treatment by pyrolysis, in which volatile or combustible components are removed from the accumulator batteries and the accumulator batteries are subsequently fed to the impact reactor. 
     
     
         14 . The method according to  claim 12 , wherein the exhaust air extracted via the suction opening is re-treated. 
     
     
         15 . A of processing mineral wool in an impact reactor according to  claim 1 , wherein the mineral wool is fed to the impact reactor and is comminuted in the impact reactor by mechanical loading of the rotor provided with impact elements, wherein the comminuted mineral wool is removed from the impact reactor via the suction opening if the particle size of the mineral wool is smaller than a predetermined particle size. 
     
     
         16 . A method processing raw material in an impact reactor according to  claim 1 , wherein the raw material is fed to the impact reactor and is comminuted in the impact reactor by mechanical loading of the rotor provided with impact elements, wherein the comminuted raw material is removed from the impact reactor via the suction opening if the raw material particles are smaller than a predetermined particle size.
