Process flow for producing 500-5000 mesh fineness talcum powder

zkj/ Release time : 2023-10-27

The principle of dry production process of talcum powder is as follows: talc block - coarse crushing - drying - medium crushing - fine grinding (Raymond mill) - ultra-fine grinding (ultra-fine grinding) - cyclone aggregate - packaging. The fineness of the final product can reach 500-5000 mesh (d97=30-5um).

The first stage: crushing

Talc bulk material is crushed by crusher to the feeding fineness (15mm-50mm) that can enter the mill.

The second stage: grinding

The crushed talc small pieces of material are sent to the bin by elevator, and then fed into the grinding chamber of the mill by vibrating feeder for grinding evenly and quantitatively.

The fine powder can be processed by LM vertical mill, MTW European mill, 5X series European intelligent mill.

For ultra-fine powder processing, MW Ring Roller Micro Mill, LUM Ultra-fine Vertical Mill can be used; for coarse powder processing, CM European Coarse Mill can be used.

The third stage: classification

The material after grinding is classified by the powder selector, and the unqualified powder is classified by the powder selector and returned to the host machine for regrinding.

The fourth stage: powder collection

The powder that meets the fineness is separated and collected with the airflow through the pipe into the dust collector, and the collected finished powder is sent to the finished product silo through the discharge port by the conveying device, and then packaged by the unified powder loading tanker or automatic baler.
