Screening equipment plays a vital role in the entire crushing production line. Appropriate screening equipment can not only increase the production efficiency of the production line, but also improve the quality of the product and increase the company's profits.

　　Basic principles for equipment selection

　　1. Construction period

　　The construction period is long. For projects with relatively concentrated crushed stone consumption, fixed combined crushing and screening equipment should be selected; for projects with short construction periods and relatively dispersed crushed stone consumption, especially long-term projects such as highways, mobile combined crushing and screening equipment is suitable.

　　2. Stone specifications

　　If the stone raw materials are more complex and the stones are of different sizes, pre-screening equipment is required; if the finished product size is larger, a larger screen size should be used.

　　3. Stone properties

　　Stones are relatively hard, so screens with strong wear resistance should be used; stones are corrosive, so screen materials with strong corrosion resistance should be used.
