影响钛白粉粒度分布的因素较为复杂，首先是水解原始粒径的大小，通过控制和调节水解工艺条件，使原始粒径在一定范围内。其次是煅烧温度，偏钛酸在煅烧的过程中，粒子经历一个晶型转化期和成长期，控制适宜的温度，使成长粒子在一定范围内。最后就是产品的粉碎，通常对雷蒙磨的改造和分析器转速的调节，控制粉碎质量，同时可以采用其它粉碎设备，例如:万能磨、气流粉碎机和锤磨装置。
The factors that affect the particle size distribution of titanium dioxide powder are more complex. The first is the size of the original particle size. By controlling and adjusting the hydrolysis process conditions, the original particle size is within a certain range. The second is the calcination temperature. In the calcination process of metatitanic acid, the particles go through a crystal transformation period and a growth period. Control the appropriate temperature to make the growth particles in a certain range. Finally, the product is crushed. Usually, the remoulding of Raymond mill and the adjustment of the speed of analyzer are used to control the grinding quality. At the same time, other grinding equipment can be used, such as universal mill, air flow mill and hammer mill.
