Calcium Carbonate Material Flow Test

Calcium carbonate is a sluggish powder that is prone to packing and sticking to vessel surfaces. It can clog hoppers, build up inside convey lines and filter bags, and cake in filter bags and cartridges. However, the material responds well to aeration. Pneumatic flow aids like AirSweep can help any factory that uses calcium carbonate achieve steady material flow.

Calcium Carbonate: Applications

Calcium carbonate is a versatile and readily-available material that is used in a number of industries.

  • Plastics, paper and paints. It is valued as a coating pigment, since it help create a bright, smooth, and light-reflecting surface. It is also an inexpensive filler and extender, and is often added to sealants and adhesives.
  • Building Materials and Construction. Calcium carbonate is used to make cement, bricks, concrete, stones, roofing and tiles, steel, and glass.
  • Pharmaceuticals. It is added to dietary supplements, and used as a base for tablets and antacids. It is added to personal care products like toothpaste, and used to bind phosphates.
  • Food processing. It is used to make baking powder, dough, wine, and dessert mixes. It is often added to animal feed.


Get the tried-and-tested solution to tough material flow problems. There are over 10,000 AirSweep systems installed all over the world. The powerful air nozzles break through material blocks to prevent bridging, arching and ratholing—and it is the only pneumatic flow aid that can handle moist, dense and viscous materials like calcium carbonate.
