The term bulk material calls a solid accumulation of particles, which are in relation to the total quantity small and from in same grain size. Bulk material is loose, dry raw ore.

A bulk material can behave therefore flow after exceeding of an activation energy as fluid. The particles remain thereby essentially, and/or change their form on the route of transportation not.

Typical bulk materials are

• Building materials: Oberboden, sand, gravel, crushed stone, cement,
• other mineral goods: Ore, thawing salt
• Food: Grain (rice, wheat etc.), sugar, food salt, coffee, flour
• powdered goods such as pigments
• Fillers, granulates, pellets

Bulk materials are often stored in silos or shelters. They are transported continuously or intermittent.

• continuous promoters:
  • Hollow belt conveyor (horizontal or light inclinations),
  • Bucket conveyors and ship unloading plants (in the vertical one or steep bevels),
  • Pneumatic fluids promotion in air flows

• Intermittent transport:
  • in bulk material areas or - shelters (e.g. ships)
  • in hollow and high on-board vehicles (truck, railway ect.)
  • in silo car (truck, railway truck)
  • in bags or Bigbags

The bulk material mechanics concern themselves with camp and terms of carriage of bulk materials such as pouring angle, discharge behavior of silos, fluidization etc.
