Equipment and process for producing lightweight calcium carbonate

Lightweight calcium carbonate, also known as calcium carbonate powder or limestone powder, is a common mineral substance used in various industries. The equipment and process for producing lightweight calcium carbonate vary depending on the production method, but generally include the following steps:

Crushing: The raw material (limestone) is crushed into smaller particles using a crushing machine, such as a jaw crusher, cone crusher, or impact crusher.

Screening: The crushed particles are screened to separate them into different size ranges. This step is usually performed using a screening machine, such as a vibrating screen or circular vibrating screen.

Grinding: The screened particles are ground into finer particles using a grinding machine, such as a ball mill or vertical mill.

Classification: The ground particles are classified into different particle sizes using an air classifier or cyclone separator.

Drying: The classified particles are dried to remove any moisture content. This step is usually performed using a drying machine, such as a rotary dryer or flash dryer.

Packaging: The dried lightweight calcium carbonate particles are packaged for storage and transport.

The specific equipment and process for producing lightweight calcium carbonate may vary depending on the raw material, production capacity, and specific requirements of the industry. In general, the production process involves crushing, screening, grinding, classification, drying, and packaging steps.
