Wollastonite processing in modern clean production
With economic development and improvement of the technological level， China's non-metallic minerals are more widely used in modern industry. Wollastonite are widely used in ceramics,paints,plastics,machinery,electronics,rubber,chemicals,metallurgy and refractory industrial sectors due to its non-toxic, tasteless, non-radioactive, non-magnetic, low oil absorption, low water absorption, high thermal and chemical stability, good dielectric properties, high brightness and excellent mechanical properties and other characteristics.
Wollastonite is a typical metamorphic minerals with low water absorption, thermal stability and conductivity, chemical inertness.It also has needle-like, fibrous crystal morphology and high whiteness and unique physical and chemical properties.
Currently, wollastonite products can be divided into two categories of needle wollastonite and fine ground wollastonite. In the application of wollastonite, most of the time require grinding and surface treatment and purification technologies.
China's production of wollastonite products block tablets, ordinary powder, powder, ultra-fine powder, needle-like powder 5 categories. Different applications for wollastonite grinding fineness, particle shape requirements vary, in general, wollastonite powder processing, in addition to reach a certain size, but also try to keep the aspect ratio of the crystal.
It is understood that wollastonite powder below 400 mesh we usually use raymond mill and ball mill to process. Ball mill is not conducive to the protection of wollastonite needle-like structure in grinding process and its power consumption is very large, which is not only a very large energy cost burden to the small and medium enterprises,but also not conform to current national's energy saving requirements.
Based on the requirements to process the wollastonite, the wollastonite mill launched by Kefid can keep its acicular characteristic well. Meanwhile its energy consumption is far below the ball mill and jet mill. The equipment is stable, easy to maintain and is ideal for wollastonite powder production companies to buy.
