Built on over twenty years of industrial screening experience and premium international manufacturing methods, YKN Series (including classic Y Series) Circular Vibrating Screens deliver powerful excitation forces for heavy-duty classification. Optimized for large block sizes and high bulk-density materials with moisture content below 5%, equipment serves as critical sizing infrastructure in mineral ore beneficiation, aggregate processing, cement production, and solid waste recycling plants.
Engineered for high-volume material classification following primary, secondary, or tertiary crushing circuits.
Handles coarse high-density iron, copper, and non-ferrous metal ores, providing precise pre-screening before secondary crushers or milling operations.
Classifies hard rock fractions including granite, basalt, and quartz into premium cubical product sizes for high-grade highway and concrete infrastructure.
Sorts large-scale limestone and raw chemical mineral inputs efficiently, maintaining high screening accuracy under heavy continuous feed loads.
Separates construction rubbish, solid waste materials, and run-of-mine coal fractions, utilizing multi-deck configurations to isolate target material dimensions.
Utilizes external block-eccentric configurations rather than conventional shaft-eccentric designs. Mechanism increases stroke amplitude while decreasing structural weight. Operators adjust auxiliary eccentric block quantities to calibrate specific excitation forces for varying processing conditions.
Finite Element Analysis (FEA) software calibrates screen box geometries for uniform stress distribution. Motors connect to exciters via flexible couplings, eliminating axial force transmission during dynamic torque transfers to guarantee exceptionally smooth operation.
Deploys synchronous toothed belt mechanisms instead of heavy gear synchronizers, reducing mechanical weight and simplifying workshop overhauls. Exciters interconnect via robust universal joints, offering high installation flexibility and rapid field replacement.
Side plates utilize single-piece integral bending without any structural weld spots, eliminating thermal fatigue crack risks. Connections between side plates, crossbeams, and reinforcing braces rely entirely on high-strength ring-groove rivets or premium bolts for uniform load bearing.
Power trains employ classical V-belt drives supported by specialized floating motor bases. Arrangement prevents axial tension force transmission during screen vibration, buffering motors against rotational shock loads and extending belt service life.
Engineered with small amplitudes, high frequencies, and large deck inclination angles to maximize material travel velocities and volumetric throughput. Exciters carry large-clearance bearings with thin-oil lubrication, ensuring low operational noise and prolonged service life.
Electric motors transfer torque through V-belts or flexible couplings to drive eccentric blocks at high rotational velocities. Fast-spinning eccentric masses generate massive centrifugal inertia forces.
Centrifugal force excites screen box side plates, forcing entire mechanical structures to oscillate in steady circular trajectories against heavy dampening isolation springs.
Raw rock fractions enter inclined screen decks. Structural momentum transmits kinetic impulses to material beds, throwing stones forward and upward in continuous, rolling leaps along screen surfaces.
Tumbling actions force material beds to stratify. Fine particles smaller than mesh openings pass downward through apertures into discharge hoppers, while oversized rocks continue traveling atop deck surfaces to separate into designated size fractions.
