Talc

Talc

Introduction

Talc is the softest mineral known, with a mohs hardness of 1. Specific gravity 2.6 to 2.8. Use your nails to make a scratch on the talc.

Talc is usually massive, foliated, fibrous, or radiating. It is white, off-white, and may be tinged with cyan or green due to the presence of other impurities. Talc is usually metamorphic from magnesium rock.

The structure of talcum powder is composed of silicon dioxide sheet at octahedral position and magnesium sheet sandwiched between sheets.

Ultrafine talcum powder is one of the largest ultrafine powder products in the world, which is widely used in papermaking, plastics, rubber, paint, cosmetics, ceramics and so on.

Resource distribution

The world's talc reserves are estimated at 900 million tons, and the world's confirmed reserves are estimated at 2.9 billion tons.

Talc (including phyllite) deposits are distributed in more than 40 countries and regions, including the United States, Brazil, China, France, Finland and Russia. In addition, there are South Korea and Japan and other countries and regions have talc deposits distribution, but the main mineral deposits to phyllite.

Talc Processing Plant

Talc is finally used in powder state, therefore, European-type plate grinding mill, Ultrafine mill, Ultrafine vertical roller mill are the necessary processing technology of talc.
In the talc production process, in summary, the production of talc is mainly three steps of beneficiation, crushing and milling. The talc processing equipment required for different steps is different. Photoelectric selection is a four different methods of talc beneficiation. After the beneficiation, the quartz and carbonate minerals are separated from the talc by crater processing and crushing and alternating circular sieves, followed by talc. The powder mill started to work.
At present, China's talcum powder processing is mainly processed by dry processing. Based on the natural crushability and grindability of talc, the talc processing equipment used is mainly Raymond machine, mechanical impact mill and airflow mill. The main processing equipment for the production of 200 mesh, 325 mesh and 500-1250 mesh talc. The dry process of talcum powder is from the selection of talc to coarse crushing. After drying and crushing, fine grinding and ultra-fine grinding are carried out. If ultrafine grinding talcum powder grinding machine is used, it is produced. The talcum powder can reach a fineness of 500-5000 mesh.
Ultra-fine talcum powder is currently used in the world's ultra-fine powder products. The applicable industries include paper industry, plastics production, paint and paint production. However, with the continuous development of the plastics industry, talc is also used to produce plastics for the automotive industry and the home appliance industry. Therefore, the market demand for talcum powder is increasing, which has also promoted the continuous innovation of talc processing equipment. The higher the application level of talcum powder, the higher the equipment requirements for the talcum powder grinding machine, the more need for ultra-fine mill, high-pressure suspension roller mill this type of talc powder processing equipment, in order to make the output value of talcum powder reflect.
