The difference between heavy calcium carbonate and light calcium carbonate

Calcium carbonate commonly known as limestone, stone powder, is an important building materials, in the industry is the raw material for firing lime and cement.

Heavy calcium carbonate, light calcium carbonate is based on the production method of calcium carbonate divided, can be distinguished from the following three aspects:

LUM-Series Ultra Fine Vertical Grinding Mill

1. The shape of the particles are different

Heavy calcium carbonate particles irregular shape, is polydisperse powder. It's large size, wide distribution. It is almost insoluble in water and heat decomposes to CaO and CO2.

2 different production process

Heavy calcium carbonate using the crushing method, containing CaCO2 in more than 90% of the Whitehead with Raymond mill or other high-pressure mill by crushing, grading, separation, and the finished product.

3. Both use different

Heavy calcium carbonate has a wide range of uses. It is filled with rubber to achieve higher tensile strength, tear strength and abrasion resistance than pure rubber sulfides.
