Square Swing Screen

1.The Inertial Rotary Screen adopts a circular motion principle, causing the square swing screen body to move in an orbital trajectory (typically low frequency and large amplitude). Materials move in a serpentine path across the screen surface, while the entire screen body swings in all directions (forward, backward, left, and right) with slight vertical motion. The Gravity Screen sifter mesh is generally made of stainless steel and equipped with polyurethane bouncing balls to prevent clogging. The amplitude (or stroke) typically ranges from 5 to 8 mm, and the operating speed is generally between 200–250 RPM. 

2.Core technical parameters include: rotation speed, amplitude, stroke, motion center positioning, and material distribution mechanism. 

3.The Square Swing screen typically consists of 1–4 layers, and can be configured in a double-deck structure, allowing for up to four different material outputs. Gravity Screen sifter is capable of producing fine sand with a particle size of 20–140 mesh. With auxiliary airflow, classification of powders in the 120–200 mesh range can be achieved. 

4.Square swing screen generally has lower throughput, with typical capacity ranging from 6 to 12 tons per hour (depending on material characteristics). For high-volume applications, multiple machines must be operated in parallel. As the separation fineness increases, throughput of the gravity screen sifter decreases accordingly.

5.Important Notes: The raw material must be dry and free of dust, especially for highly absorbent powders or spherical granules.

The Gravity Screen sifter is suitable for quartz sand, chemical raw materials, metallurgical and building materials, as well as food and pharmaceutical ingredients.

1.Chemical Industry 

The square swing screen is employed to classify and separate chemical powders and granules, ensuring uniform particle sizes for products like fertilizers, resins, and detergents.

2.Food Processing

In the food industry, the Inertial Rotary Screen is used to sift and grade ingredients such as flour, sugar, salt, and starch, maintaining product quality and consistency.

3.Metallurgy and Mining

The Gravity Screen Sifter plays a crucial role in the classification of metal powders, ores, and minerals, facilitating efficient downstream processing.

4.Pharmaceuticals 

The square swing screen ensures the precise separation of pharmaceutical powders, contributing to the production of high-quality medicinal products.

5.Environmental Engineering

The Inertial Rotary Screen is utilized in waste management and recycling processes to separate and classify various materials, enhancing the efficiency of recycling operations.

1.Screen Box: Green surface of the Square Swing Screen is designed to withstand the dynamic forces generated during operation and is typically constructed from high-strength materials to ensure durability.

2.Vibrator Mechanism: The vibrator, often driven by an unbalanced motor or eccentric shaft, generates the gyratory motion necessary for material separation. This motion of Inertial Rotary Screen ensures that materials move in a controlled path across the screen surface.

3.Screen Mesh: Attached to the Gravity Screen sifter box, the Inertial Rotary Screen mesh comes in various materials and aperture sizes, allowing for precise separation of different particle sizes. The mesh is often equipped with cleaning devices, such as bouncing balls, to prevent clogging.

4.Spring System: Located beneath the screen box, springs absorb vibrations, prevent structural damage, and ensure smooth operation. They play a crucial role in maintaining the stability of the machine during operation.

5.Motor: Provides the necessary power to drive the vibrator mechanism, initiating the gyratory motion of the screen. The motor's specifications are selected based on the desired screening capacity and material characteristics.

6.Support Frame: A robust structure that holds the entire assembly in place, ensuring stability during operation. It is designed to support the dynamic loads and vibrations generated during the screening process.

7.Inlet and Outlet Chutes: Guide the material onto the Gravity Screen sifter and collect the separated fractions, respectively. These chutes are designed to facilitate smooth material flow and minimize spillage.
