The square gyratory sifter, referred to as reciprocating screen, is a new type of efficient screening equipment developed and designed to meet the needs of users with large output and high precision.
The square gyratory sifter is modeled after the manual screening principle to do slight elliptical swing and upward arc motion, especially suitable for cylindrical, sheet and other irregular materials, with high screening efficiency, large output, long service life and other advantages, and the equipment is easy to install and use, easy to use the assembly line.
The square swinging screen can screen one to five layers of screens, and can simultaneously perform two to nine grades of classification or filtration. Mainly used in chemical and new materials, metallurgy, mineral powder, food, abrasives and other industries.
One machine is divided into two or more groups
The screening capacity is large, and the multi-layer classification design is used. One machine is divided into two or more groups. One machine can be used as multiple machines, and the output is doubled.
6-level classification
Up to 5 times the output per unit area; accurate to 6-level separation, the screening efficiency is as high as 90%-99%.
New process
Large-scale electrostatic spraying process, the equipment is more beautiful, wear-resistant, and rust-proof, with low noise<75.
New process
Flexible screening, acceleration is 4-5 times lower than that of ordinary vibrating screens, and the service life is increased, thereby reducing maintenance costs.
Convenient operation
Net replacement is more convenient, simple to operate, firm and reliable.
Green and environmentally friendly
Fully enclosed structure, no dust flying, small vibration and low noise of the screening machine, improve the working environment of the workshop, and meet environmental protection requirements.
Revolving around the motion trajectory of its screen box, the square gyratory screen, or arc screen, harnesses inertial forces from its driving mechanism. This force, generated by the eccentric wheel's rotation around a fixed axis, drives the screen box to reciprocate. This reciprocating motion impels the screen surface to oscillate periodically, facilitating directional movement of screened materials. Particles smaller than the screen aperture fall through, while larger ones undergo continuous rolling and jumping before discharge, completing the screening process.
The square gyratory sifter comprises essential components such as the feed inlet, screen box, drive unit, screen frame, support structure, vibration dampers, and discharge outlet.
Feed Inlet: Modified with an enhanced material distribution plate structure for more effective and uniform material dispersion onto the screen surface, optimizing screening efficiency.
Screen Box: Includes the screen frame, screens, screen mesh, spring clips, and bouncing balls. Screens are tensioned on the mesh via spring clips, with bouncing balls aiding in screen cleaning.
Drive Unit: Features a driver, motor, locking sleeve, locking nut, stop washer, and cone sleeve. The cone sleeve secures the drive shaft within the screen frame, ensuring stable operation.
Universal Shaft: Connects the entire screen box, rotating in tandem with the screen motion to buffer and dampen rotational forces, enhancing overall operational smoothness.
Discharge Outlet: Customizable to accommodate diverse material screening needs, ensuring unimpeded flow and efficiency with various discharge angles and enlarged diameters.
| Model | Screen size | Screening area | Screen inclination | Layers | Power | Number of turns | Case travel |
| FYBS1536 | 1.5*3.5 m | 4.5-9 ㎡ | 0-5° | 1-10 | 5.5 kw | 180-260 | 25-60 mm |
| FYBS2040 | 2.0*4.0 m | 8-9 ㎡ | 0-5° | 1-10 | 7.5 kw | 180-260 | 25-60 mm |
The square gyratory sifter accommodates one to five layers of screens, capable of performing two to nine levels of grading or filtering simultaneously. Widely utilized in chemical and new material industries, metallurgy, mineral powders, food processing, abrasives, and more.
Materials Suitable for Screening
Materials include quartz sand, industrial salts, frac sands, manufactured sands, drying sands, ceramsite sands, silica sands, polypropylene, drying mineral powders, calcium carbonate, mica powders, talcum powders, river sands, fertilizers, quartz sands, perlite, graphite, mung bean, Longyan ore sands, metal powders, and metal silicon, among others.
Common Specifications of Quartz Sand:
0.5-1mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh. The above meshes can be effectively screened using a square swing screen, with a single unit producing 5 to 50 tons per hour and a screening accuracy of more than 98%, which meets the requirements for the use of petroleum proppants.
