Frac Sand Gyratory Screen

Rectangular Gyratory Sifter Machine is also called reciprocating screen / square tumbler screen, if see from the motion trail of screen box. The vibratory force produced by its driving device is the inertial force twining along the dead axle, the direction of which is change according to a certain regular.

Rectangular Gyratory Screen

Rectangular gyratory screen, also known as a gyratory sifter or gyratory separator, is a specialized vibrating screen used in various industrial applications to separate materials based on particle size. The name "gyratory" comes from its gyratory motion, which is a circular movement with a combination of horizontal and vertical motion.

Gyratory screens are commonly used in various industries, including food processing, pharmaceuticals, chemical engineering, mining, and agriculture. They are particularly useful for sifting and classifying bulk materials, ensuring the quality and consistency of the end product, and removing impurities or oversized particles.

Advantages of Gyratory Screen

High capacity: Gyratory screens have a larger screening area compared to other types of vibrating screens. This allows for higher throughput and processing capacity, making them suitable for applications with high volumes of material.

Efficient screening: The gyratory motion of the screen helps to promote efficient and accurate screening of materials. It allows for the separation of particles based on size, shape, and density, ensuring a precise classification.

Multiple deck configurations: Gyratory screens can be equipped with multiple decks, allowing for the simultaneous separation of materials into different fractions. This versatility enables the screening of a wide range of particle sizes.

Easy maintenance: Gyratory vibriting screens are designed with easily accessible components, making routine maintenance tasks straightforward. This helps to minimize downtime and ensure optimal performance of the equipment.

Versatile applications: Gyratory screens are used in various industries, including food and beverage processing, pharmaceuticals, chemicals, minerals, and more. They are suitable for screening powders, granules, particles, and other solid materials.

Sanitary design: For industries with strict hygiene standards, such as food and pharmaceuticals, gyratory screens can be manufactured with sanitary materials and designed with smooth surfaces to facilitate easy cleaning and comply with industry regulations.

Working Principle

According to the structure characteristics and working principle of swinging screen, the screen surface is arranged with level or incline (angle of inclination is 0-5 degree). After turn on the swinging screen, the screen box take reciprocating movement under the inertial force, screen box drives screen surface to make periodic shaking, which makes the materials on the screen surface to make directional jumping movement with the screen box. During the period, the material less than the screen aperture falls to under layer, the material bigger than the screen aperture make jumping movement, discharged from the coarse outlet.

This equipment is a super-square tumbler screen (SYT-FYBS) model developed and produced by our company with a hanging structure. It has applied for a number of national protection patents and is leading the industry. The screen mesh frame and the screen mesh installation method adopt a unique and innovative design, and the installation is very convenient. Usually 9-layer design can be divided into 10 grades at one time, or 4 layers + 4 layers equivalent to 2 sets sieve machine, or 2 layers + 2 layers + 2 layers equivalent to 3 sets sieve machine, or designed as 1 layer +1 layer +1 layer +1 layer +1 layer is equivalent to 5  sets sieve machines.
