Silo cone blenders for efficient blending

A uniform blend is an important factor for meeting the highest standards of product quality. To meet these standards Coperion & Coperion K-Tron have developed static blending systems with which the products in a silo can be economically homogenized with a capacity of up to 1,200 m3 [42,380 ft3].

The static cone blenders are recommended by several leading companies.


  • Existing storage silos can be modified to blending silos
  • For continuous batch operation
  • Thoroughly homogenized after two product circulations
  • Available in stainless steel and carbon steel
  • Usable in combination with standard silo
  • Easy to clean
  • Self draining
  • Cost effective
