In a dry mix mortar plant, the screening machine serves as a core auxiliary device that guarantees raw material purity and regulates batching precision. It is primarily employed for the classification and screening of key raw materials like sand, eliminating impurities and particles with unqualified sizes, and establishing a solid foundation for subsequent mixing and blending procedures. The commonly utilized screening machine types in the plant mainly include circular vibrating screen, probability screen, flat screens, and linear screens—among these, circular vibrating screen and probability screen are the most widely adopted.

The sand batching in a dry mix mortar plant imposes strict particle size standards, typically ranging from 0 to 2.5mm, which sets high demands for the accuracy and efficiency of the screening machine. Most domestic and overseas dry mix mortar plant manufacturers prioritize circular vibrating screen and probability screen as their primary screening equipment, as they feature a clear division of labor and strong complementarity: the circular vibrating screen is ideal for screening fine-grained sand and gravel, offering meticulous screening and high precision to effectively filter out materials that meet fine-proportion requirements; the probability screen excels in classifying coarse-grained sand and gravel and stands out as a highly efficient and energy-saving screening machine.
Circular Vibrating Screen Working Principle
The probability screen, a specialized screening machine in the dry mix mortar plant, boasts remarkable advantages such as high screening efficiency, compact structure, large processing capacity, and superior screening accuracy. It also occupies minimal space and is lightweight, with a closed design that effectively controls dust leakage to comply with industrial environmental regulations. This screening machine can achieve up to 6 material classifications in a single screening run, with low operational noise and energy consumption, ensuring strong practicality. Additionally, based on the dry mix mortar plant's design requirements, the screening machine—whether circular vibrating screen or probability screen—can be equipped with auxiliary systems like pneumatic screen cleaning, screen monitors, operation and overload monitors, and spray dust suppression systems, enabling comprehensive detection and control. When connected to the central control system, this integrated setup helps the dry mix mortar plant achieve fully automated operation, enhancing production efficiency and stability.
