Conversion Method of Rotary Vibration Screen Mesh Size

A lot customers only knows the micron term and don’t know the meaning of mesh when purchasing a rotary vibrating screen. In fact, the conversion of micron into mesh is simple. Let’s PK Machinery explain the specific conversion method. 

 

At first, let’s us briefly understand what is mesh definition. The mesh refers to the number of inches of screen holes per square. 50 holes per square inch refer to the 50 mesh. The bigger the number of mesh means the more holes per square inch. Besides, it also used to express the screen mesh particle size. The higher the number of mesh means the smaller the particle size.

 

 

The powder particle size is known as particle size. The granularity means particles can pass through the screen mesh size with 1 inch (25.4 mm) the number of mesh width of the screen mesh representation is known as mesh. There is no unified standard size of powder technology in the world. Each enterprise has its granularity index definition and representation. Different country has different screen size. Hence, it is difficult to be standardized. 

China adopts American Standard.
