BLOWBARS
 
  Crushing activities in mining, quarrying or recycling industries are carried
  out by the several types of impactors, i.e. Vertical Shaft Impactors (VSI) or
  Horizontal Shaft Impactors (HSI). In the particular case of a horizontal shaft
  impactor, the rotor is the central part in the machine. That can be fitted either
  with four laterals of x hammers or with four blowbars positioned in a star shape.
 
  When turning, the rotors will rotate the hammers or blowbars at a certain speed
  in order to break the raw material fed in through the top of the machine.
  According to the machine type, Magotteaux develops different designs and
  manufactures different alloys of blow-bars (and hammers too).
 
The target is to find the design that will break the raw material at the highest efficiency according to the predefined criteria of shape, size,…) and the alloy that will resist against wear and shocks in order to keep the blowbar’s original profile constant, and hence enable the best performance in terms of quantity (tons crushed per day) and quality (requested cubicity, granulometry, …).
 
Here is the product portfolio;
 
MARTENSITIC STEEL + Xwin®
