introduction of Talc


Talc is a type of hydrotherm alteration ore. After alteration, magnesite ore will becomes to talc, therefore talc is often seemed like olivine, enstatite, hornblende, tremolite. Talc is normal silicate minerals, and it is soft and creamy. Talc is the softest ore, Moh's hardness 1. Soft talc could be used to draw like chalk does. Talc exists in bulk, blade, threadiness or radial shape present white or gray, talc could present different color as the impurity contained, and hydrated magnesium silicate is the main element.Talc


Technological Process of Talc


Talc should be processed by powder grinding machine to different fineness for further appliment. With application range expanded, talc grinder mill is produced frequently and sold better. Aim to talc process, Winnermac powder grinding mill can process above 20mm material whose Moh's hardness is less than 6, and material should be non-flammable. Grinding roller assembly and roller were changed, material should be ground for many times from top to bottom, grinding rollers’ centrifugal force will be fully utilized, contact area of material and roller is large, fine powder would be produced, final size range between 5-45 micron.


Application Fields of Talc


Talc has wide application area, for example, refractory matter, paper making, padding, insulating material, lubricant, pesticide absorber, leather coatings, and carving material. According to its application, talc could be divided into cosmetic grade, medicine and food grade, coating grade, paper making grade, plastic grade, rubber grade, cable grade, ceramic grade, fine talc powder, waterproof material grade, and talc products application area is very wide.
