Vibrating screens serve as the core component of aggregate production line. It directly determines sand grading accuracy, finished product quality, screening efficiency and output stability. Premium screen mesh reduces blockage, cuts maintenance costs and ensures stable sand production.
HFG High-Frequency Vibrating Screen
● High Throughput & Superior Screening Efficiency
As a mature high frequency vibrating screen, this vibrating screen delivers prominent processing edges in productivity and classification precision.
● Low Amplitude Design
Low vibration amplitude enables fine particles to readily approach the screening surface of the high frequency vibrating screen, boosting fine fraction separation probability and substantially upgrading overall screening efficiency of this vibrating screen.
● High-Frequency Vibration Feature
High-frequency excitation delivers vibration force directly onto the screen mesh of the high frequency vibrating screen to accelerate rapid material stratification, effectively preventing screen blinding. With auxiliary air flow, its minimum separation cutoff reaches 300 μm.
● External Quick Tensioning System for Screen Mesh
An externally mounted rapid tensioning mechanism facilitates fast screen replacement on the vibrating screen, prolonging equipment uptime and cutting maintenance expenditure significantly for the high frequency vibrating screen.
● Static Screen Frame Construction
The screen frame of the high frequency vibrating screen remains stationary during operation, lowering foundation and installation investment for the vibrating screen; meanwhile, the unit allows easy full enclosure for superior dust containment and environmental compliance.
● Lower Energy Consumption & Eco-Friendly Operation
Under identical processing capacity, this high frequency vibrating screen as a typical vibrating screen consumes less power to slash operational costs, paired with low noise emission for favorable working surroundings.
● Capacity Parameter
For finished products finer than 2 mm, hourly output of the high frequency vibrating screen ranges from 10 to 50 metric tons.
SG Square Gyratory Screen / Square Swing Screen
The square gyratory screen works as an alternative to conventional vibrating screen, and this square swing screen operates on circular vibration principle to drive the screen deck into orbital movement with low frequency and large stroke. Materials travel in serpentine paths across the screening surface as the square gyratory screen body sways horizontally in all directions accompanied by slight vertical oscillation for grading. Stainless steel is commonly adopted for screen cloth of the square gyratory screen, fitted with polyurethane bouncing balls to eliminate screen blinding. Its standard stroke ranges 5–8 mm with rotational speed of 200–250 RPM.
Square swing screen production trial run
Core technical parameters of the square swing screen include rotating speed, stroke length, gyration center position and feed distribution assembly.
Available with 1 to 4 screening decks or double-layer composite configuration, the square swing screen can yield up to four graded finished products for fine sand ranging from 20 mesh to 140 mesh. Auxiliary air assist enables ultra-fine powder separation down to 120–200 mesh on the square gyratory screen.
Square swing screen arrangement
The square gyratory screen features moderate throughput of 6–12 metric tons per hour subject to feedstock characteristics; multi-unit parallel installation of the square gyratory screen is required for high-capacity demands, with output declining as separation fineness increases.
Operating Note: Raw feed must be dry and free of excess fines, especially highly hygroscopic powders and spherical granular materials before feeding into the square gyratory screen.
