Talc, also known as painted stone, liquid stone, delite, cold stone, guava, and co-stone, is a common silicate mineral with a Mohs hardness of 1. It is the softest known mineral and can replace chalk. Draw white marks, scratches can be left on the talc with your fingernails.
Talc is generally in the form of lumps, leaves, fibers or radials, and the color is white, off-white, and various colors due to other impurities.
| Equipment list | Talc mill, jaw crusher, bucket elevator, electromagnetic vibrating feeder |

| Mohz hardness | Mohs about 1 degrees |
| Feeding size | <40mm |
| Capacity | 0.5-60t/h |
| Output size | 30-425mesh |
| Application | Such as stone flour, barite, bentonite, calcium carbonate, clinker, coal, dolomite, lead oxide, limestone, marble, quartz, ultrafine. |
Talc milling is generally divided into talc coarse powder processing (0-3MM), fine powder processing (20 mesh-400 mesh), and ultra-fine powder processing of talc (400 mesh-1250 mesh) and micro powder processing (1250 mesh-3250 mesh) ) four types.
Stage 1: Crushing
The talc bulk material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.
Stage 2: Grinding
The crushed talc small pieces are sent to the silo by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the vibrating feeder for grinding.
For fine powder processing, Vertical roller mill, MTW European version mill, and European version intelligent pulverizer are generally used; for ultrafine powder processing, HGM ultrafine vertical mill is generally used, and for coarse powder processing.
Stage 3: Grading
The pulverized material is classified by the powder separator, and the unqualified powder is classified by the powder separator and then returned to the main engine for re-grinding.
Stage 4: Gathering Powder
The powder that meets the fineness enters the dust collector through the pipeline with the air flow for separation and collection, and the collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then uniformly packed by a powder tanker or an automatic baler
