Product Overview

A Square Gyratory Screen, also known as a reciprocating screen or precision screening machine, is a high-efficiency screening system designed for high-precision separation and high-capacity processing. It features effective screen self-cleaning, high utilization of the screening surface, extended screen service life, and excellent sealing performance. The screening decks are typically installed horizontally or at a slight incline.

Square gyratory screens are widely used in the chemical, advanced materials, carbon and graphite, quartz sand, metallurgical, metal powder, mineral powder, food, and abrasive industries. Depending on specific screening requirements, the equipment can be configured with single or multiple screening decks.

The square gyratory screen mainly consists of a feed inlet, discharge outlets, screen mesh, screen box, drive system, and vibration-damping components. It features a practical and advanced structural design, stable and reliable performance, easy operation and maintenance, high processing capacity, low operating noise, corrosion resistance, adjustable amplitude, low energy consumption, easy installation and commissioning, cost-effective construction, easy and thorough cleaning, and effective dust containment.

Product Features

1. High Screening Capacity

Featuring a unique multi-deck classification design, a single unit can perform multiple screening and classification processes, helping replace multiple conventional screening machines while significantly increasing throughput and production efficiency.

2. Fully Enclosed and Environmentally Friendly

The fully enclosed design effectively prevents dust leakage and airborne dust. Low equipment vibration and low operating noise help provide a cleaner working environment and meet environmental protection requirements.

3. Flexible Screening and Easy Maintenance

The flexible screening design allows for quick and convenient screen replacement. The equipment is easy to operate, robust and reliable, and designed for long service life, helping reduce maintenance frequency and overall maintenance costs.

Working Principle

The motion of the screen box is generated by the reciprocating inertial force produced as the eccentric wheel rotates around a fixed axis. Based on the structural design and operating principle of the square gyratory screen, the screening deck is typically installed horizontally or at a slight incline.

Once the machine is started, the screen box moves back and forth under the action of inertial force, driving the screening deck in a periodic reciprocating motion. Material on the deck moves together with the screen box, undergoing controlled jumping, rolling, and forward movement across the screening surface.

Particles smaller than the screen aperture pass through the openings and fall onto the lower deck as undersize material, while particles larger than the screen aperture continue to roll and move across the screen surface before being discharged through the outlet. In this way, the material is efficiently separated and classified by particle size.
