International technology group ANDRITZ has received an order from the Spanish pulp and paper producer Papelera Guipuzcoana de Zicuñaga to deliver a new LimeFlash-H lime kiln for its pulp mill in Hernani, Spain.

The ANDRITZ scope of supply includes:

  • LimeFlash-H Feed head system
  • Lime kiln

The ANDRITZ LimeFlash-H is a completely new feed end technology for maximizing the efficiency of the lime kiln and with focus on further increasing the capacity of the lime kiln while reducing energy consumption at the same time. This next-generation LimeFlash-H technology consists of a 2-cyclone system combined with ANDRITZ state-of-the-art LimeFlash feed end technology.
