In papermaking industry, fine calcite powder and barite powder are increasingly used as filler which are of more advantages than usual materials. The fineness of grinded calcite or barite powder is 1250 mesh. Considering about the fineness and final capacity, Clirik  will offer you calcite, barite ultrafine powder production line and grinder machine with both open circuit and closed circuit available.

Papermaking introduction:

Calcite and barite after ultrafine grinding (1250mesh) are two important materials of papermaking industry. Calcite which is also called calcium carbonate has been used as popular filler replacing usual talc and kaolin. Similarly, barite powder is also widely used as filler in papermaking.

Clirik has been engaged for decades in ultrafine mill equipment R&D and manufacturing. Our HGM Ultra-fine Mill which adopts advanced Sweden technical innovations can meet your calcite and barite processing requirement for papermaking industry.

Raw materials of papermaking industry:

Raw material: Calcite and barite

Fineness requirement: 1250mesh

Calcite and barite grinder machine: HGM Ultrafine Mill

Clirik can offer these grinding mills to pulverize your calcite or barite to be 1250mesh:

Calcite and barite ultra-fine grinder machine (325~2500mesh)

Clirik offers customized ultra-fine grinder machine for calcite and barite powder production used in papermaking or other industries. The HGM Ultrafine Mill is proved to be the most favored grinder machine by our customers. The final fineness is adjustable from 325mesh to 2500mesh. And the equipped pulse filter and sound absorber can reduce greatly powder and noise pollution.

Calcite and barite ultra-fine grinding process (final powder fineness: 1250 mesh)

After being redacted by hammer crusher, limestone and barite materials are sent to storage bin by elevator. Then they are sent by electromagnetic vibrating feeder to the center of dial evenly and ground and pulverized into fine grains by roller. Then grains descend to the second and third ring for further grinding. The high pressure centrifugal blower blows the grains to powder classifier for classification. Calcite and barite powder of 1250mesh or less in size passes the classifier to be discharged as final product, while coarse grains are sent back to grinding chamber for further grinding.
