Heavy (Ground) Calcium Carbonate is widely used as filler and improver.
Purity: 98%min.
Appearance: white powder.

Heavy calcium carbonate, also called ground calcium carbonate, is produced by natural superior calcite, which has high purity and whiteness. The size ranges from under 400 mesh which is called primary products, to 2000 mesh or above, depending on your requirement.

Heavy (Ground) Calcium Carbonate is widely used as filler and improver in plastic, paint, paper-making, rubber, pharmacy, feed, daily chemical, ceramics, adhesives and ink industry.

Calcium carbonate Application:

1)Rubber:

it can reduce the amount of expensive natural rubber,increase its volume ,reduce costs, After adding calcium carbonate then can be obtain higher strength tensile ,tear strength and abrasion resistance than the pure Rubber vulcanizate

2)Chemical manufacturing materials 

it is heat-proof, chemical corrosion-proof,cold-proof, anti-noise, shockproof and easy to process. Therefore it can be used to make doors, dry motar ,ceilings, wallboard,waterpipe,handrail of stairs,floor board and electric wire,etc.

3)Painting& coating: 

it is as the filling and as the framework, Latex paint more than 30% amount are used in thick paint ,26%-60% amount are used in water-based pain

4)Plastic: 

it can increase the volume of plastics, reduce the costs, improve the size, stability, hardness and tenacity of plastic products.

5)Paperpulp material: 

it can fully make use of its high whiteness, affinity to water and shock intensity, low cost widely using .

6) Coal-fired power and planted sulfurization

7)Feed,pharmaceutical industry

 making calcium additives, replace the original shell powder to reduce costs.
