By speed variation of reciprocating conveyor more green pellets will be charged on outside than on inside in order to achieve level pellet surface.
Benefits of a CPT Plant
Compact plant layout, low building profile, short process air ducts, standardized equipment.

Environmental compatibility: 100% recycling of by-products, processing of in-plant waste materials
- Combination with MEROS Technology for Desulphurization of Waste Gas (Hydrated Lime or Bicarbonate based)
- Active Carbon Addition for Removal of Heavy Metals in Waste Gas
- Reduction of NOx by Ultra-Low-NOx Burner Technology or Selective Catalytic Removal
- Re-utilization of approx. 10 % of Steel Work Waste Materials in the Pelletizing Process
- Re-use of Pelletizing Plant Discharge Materials in the Pelletizing Process by Regrinding
