Crushing requirements for particle size and particle size distribution of pigmented titanium dioxide

Pigment titanium white has very strict requirements on particle size and particle size distribution. There are two types of industrial crushing methods for titanium dioxide: wet crushing and dry crushing. Wet crushing equipment include wet ball mills and sand mills, both in the medium of water.

Dry crushing equipment include Raymond mill, hammer mill, centrifugal mill, flow energy mill (air flow crusher), etc. Crushing can also be used without a single grinding equipment, but by a combination of two or more grinding equipment, such as the calcined material first by the ring roller grinding and then by airflow crushing, but also with the same equipment for repeated grinding, such as secondary airflow destruction. The following is an example of Raymond mill to give you an introduction of its crushing principle.

Raymond mill is also called ring roller mill, and swing wheel type ring roller mill is used in titanium white industry. Raymond mill can be used to crush non-pigmented titanium dioxide products, and also used in the primary crushing of pigmented titanium dioxide. Because of its internal separator, it has much less coarse particles in the product than other dry mechanical mills (such as centrifugal mills). Other materials wear less pollution, large output, electricity saving, so it is widely used abroad for primary crushing of anatase and rutile titanium dioxide and secondary crushing of anatase titanium dioxide (water selection, drying after crushing).
