Blending Beds for Bulk Materials

Longitudinal or circular stockpiles are used to mix or homogenise raw materials such as coal. A distinction is made between longitudinal and circular stockpiles - both have a reserve or interim storage function.

Various Stockpile Layouts are Possible

The shape of the stockpile depends on the space available and the volume of the material to be stored. A rotary spreader is used to fill the stockpile, and material is taken from the pile using a scraper chain with buckets.

Based on the specific task (buffering, collecting and distributing, blending/homogenising) and the resulting incoming and outgoing material flow, first the storage capacity is decided upon. Together with the material properties this then leads to a choice of available stacking and reclaiming methods as well as the two basic stockpile layouts, namely the longitudinal stockpile arrangement and the circular stockpile arrangement.

Longitudinal Stockpile Arrangement

  • High Storage Capactiy (up to > 1,000,000 t)
  • Active Storage Volume smaller than Circular arrangement
  • Passive storage can be added on easily

Circular Stockpile Arrangement

  • Low Storage Capacity (up to 100,000 To)
  • Live storage volume higher than longitudinal storage
  • No increase in storage space possible
