The mesh size of the material being screened is a crucial parameter when selecting screening equipment. Choosing the appropriate screening equipment during material screening improves screening efficiency and material quality. Different processes and procedures require different types of screening equipment. Today, we'll discuss how to select screening equipment for materials with different mesh sizes.

Screening 6-140 mesh materials:

When screening 6-120 mesh materials, considerations include production capacity, screening accuracy, and dust emission. Materials within this size range typically have a production capacity of 15-50 tons, require an accuracy of at least 95%, and have correspondingly high environmental requirements. Traditional linear screens or heavy-duty screens cannot meet these requirements. For this type of material, a square oscillating screen is recommended.

The gyratory vibrating screen, with its high throughput and high-precision screening capabilities, has become the preferred screening equipment for many industries. Using the excitation force generated by a vibrating motor, it creates a three-dimensional trajectory (horizontally, vertically, and tilted) to simulate "shaking and tapping," causing the screen surface to produce a reciprocating oscillating motion at a defined angle. This motion not only promotes the tumbling and dispersion of the material on the screen surface, but also increases the contact between the material and the screen mesh, thereby improving screening efficiency. While maintaining screening accuracy, the gyratory vibrating screen effectively addresses the problems of clogging and low screening efficiency associated with traditional vibrating screens.

Screening 100-500 mesh materials:

When screening 100-500 mesh materials, considerations must be given to screening accuracy, material properties, and screening rate. Fine materials often suffer from high viscosity, agglomeration, and electrostatic adsorption, leading to problems such as limited production capacity and fluctuating accuracy. For these materials, a tumbler vibrating screen is recommended.

Tumbler vibrating screens are widely used in daily production screening and impurity removal operations. They are a highly efficient screening device designed to meet the needs of users seeking high-volume and high-precision screening. The core advantage of circular vibrating screens lies in their unique oscillating motion. Unlike the continuous rotation of traditional screening equipment, they use a reciprocating motion, achieving more precise and uniform screening of materials. This motion not only improves screening efficiency but also extends the life of the screen mesh. They are widely used in industries such as food processing, pharmaceutical production, chemical production, metallurgy, and building materials processing.

Screening of Large Particle Materials:

When screening materials larger than 6 mesh, production capacity and equipment life must be considered. For these materials, large linear vibrating screens or heavy-duty vibrating screens are recommended. These screens offer a simple structure, high production capacity, easy operation, and a long service life, making them a common screening device for large particle screening operations.

When selecting screening equipment, users can systematically consider key points. The most suitable screening equipment for their needs is not necessarily the most advanced technology, but rather a screening equipment system solution that matches the characteristics of the material being conveyed, the scale of production, and the process requirements.
