Our company's WR2300V 600 horsepower full hydraulic cold recycler is an upgrade and improvement of the WR2300E. The milling capacity of the machine has been greatly improved. The working speed has been upgraded from 3 to 8 speeds. It has a wider range of speed adjustment. The speed can be increased by more than 30%, which greatly improves the working efficiency of the machine, reasonably adjusts the milling speed, the same cutter head extends the service life, has better economy, and has better water-stable roadbed regeneration with different strengths. Adaptability, better control of regeneration granularity.
