4机械粉碎法制备超微粉超细粉碎方法主要是机械粉碎，包括高速机械冲击式磨机、气流磨、振动磨、搅拌磨、胶体磨、雷蒙磨、球磨机等粉碎设备。超微机械粉碎是在传统的机械粉碎技术基础上发展起来的。粉碎作用力的类型如图历所示。各种粉碎设备，其粉碎作用力一般不是单一的，而 4 mechanical crushing method of ultrafine powder ultrafine grinding method is mainly mechanical crushing, including high-speed mechanical impact mill, jet mill, vibration mill, stirring mill, colloid mill, Raymond mill, ball mill and other crushing equipment. Ultra-micro mechanical crushing is based on the traditional mechanical crushing technology developed. The type of shredding force is shown in the figure. A variety of crushing equipment, the crushing force is generally not a single, and
