Pugmill Granulation

Uhde offers its customers many years of expertise and experience in chemical plant engineering - from the execution of process studies to the handling of projects on an EPC basis.

Our portfolio includes state-of-the-art processes for the production of ammonium nitrate solution (AN) as feedstock for all types of AN processes, such as the production of AN/CAN granules in pugmill granulation.

Uhde offers plants for the production of AN/CAN with a capacity of up to 2,000 mtpd CAN and is one of the leading licensors of these processes.

The heart of the process is the pugmill granulator - a horizontal mixing and granulation apparatus in which the recycled material (oversize, undersize, filler) and the AN melt are mixed to produce granules.

The Uhde® Pugmill granulation process is characterized by:

  • high product quality according to international standards

  • high capacity: installed capacity of up to 2,000 mtpd CAN 27

  • patented process for reuse of process air in the product cooler (reduction of CAPEX and OPEX)

  • emission values for ammonia and dust correspond to BAT values (BAT - best available technology)

  • flexibility: AN 33.5%N, CAN 27%N and CAN-S can be produced in the same plant

  • Cost efficiency

All the above mentioned processes are proven by references.
