Screening equipment grades crushed materials by particle size, and screening equipment also performs dewatering, desliming and medium removal, so screening equipment meets diverse industrial production demands.
We classify screening equipment by structure, material motion and usage: structural screening equipment includes fixed, roller, trommel, curved and fine screens; motion-based screening equipment covers elliptical, circular vibrating screen and linear vibrating screen; functional screening equipment has pre-screening, finished-product and control types. Each screening equipment fits specific scenarios: circular vibrating screen handles coarse lump materials well, while linear vibrating screen suits medium-fine particle grading and dewatering.

Square Gyratory Screen
● Description
A square gyratory screen is driven by motor exciters and universal joints to create 3D elliptical swing motion, and a square gyratory screen extends material residence time for high-precision fine screening. A square gyratory screen lets fine particles pass meshes and discharges oversize materials to finish separation steadily.
Operational Footage
● Advantages
A square gyratory screen adapts to dry/wet granular/powder materials, needing no extra screening equipment; a square gyratory screen ensures high throughput and accuracy with little screen blinding; a square gyratory screen enables fast screen replacement for low downtime; a square gyratory screen runs quietly without damaging materials.
High Frequency Vibrating Screen
● Description
A high frequency vibrating screen runs at high frequency and low amplitude to agitate fine particles, break material surface tension and realize solid-liquid separation, so a high frequency vibrating screen works for fine coal, mineral powder and slurry processing.
● Advantages
A high frequency vibrating screen achieves 70%–95% screening efficiency for fines; a high frequency vibrating screen cuts power use versus ordinary screening equipment; a high frequency vibrating screen has high unit-area throughput for mass production; a high frequency vibrating screen self-cleans meshes to reduce maintenance; a high frequency vibrating screen installs flexibly without complex foundations.
Linear Vibrating Screen
● Description
A linear vibrating screen takes vibration motors as exciters to drive linear forward material tossing, and a linear vibrating screen is core screening equipment for powder/granule screening, grading, dewatering and impurity removal.
Working Principle
● Advantages
A linear vibrating screen has 1.5–2× throughput of a circular vibrating screen; a linear vibrating screen features high energy efficiency and low noise; a linear vibrating screen's adjustable parameters match different precision needs; a linear vibrating screen has compact horizontal layout to save plant space; a linear vibrating screen's fully sealed design fits dry screening equipment applications.
Circular Vibrating Screen
● Description
A circular vibrating screen generates centrifugal force via high-speed rotating eccentric parts to drive circular screen box vibration, and a circular vibrating screen feeds materials from its upper end. Under vibration of a circular vibrating screen, materials stratify: fine grains pass meshes, and coarse ones exit the circular vibrating screen's outlet.
Working Principle
● Advantages
A circular motion screen reaches 85%–92% efficiency with prolonged material residence time; a circular vibrating screen delivers large throughput via inclined meshes and fast vibration; a circular vibrating screen avoids clogging through particle dispersion; a circular vibrating screen has reliable simple structures for easy screen and vibrator maintenance.
