What Is a Vibrating Screen?
High‑Load Ore & Aggregate Classification

Heavy‑Duty Mechanics for Impact Resistance
Reinforced side plates and beam work pair with a rugged eccentric drive to generate 9.5 – 11 mm double‑amplitude vibration (> 5 g), allowing the screen to absorb large, sharp‑edged stone without structural fatigue.
Adjustable Speed Matches Changing Feed Conditions
Three preset running speeds—708, 755 or 845 rpm—let operators tune throw and residency time as ore density, moisture, or gradation shifts, preventing bed build‑up and mesh blinding during peak tonnage.
Multi‑Deck Polyurethane & Wire Mesh Layouts
Single, double, or triple deck configurations combine abrasion‑proof polyurethane panels with quick‑change wire cloth to deliver simultaneous 40 mm, 5 mm, and 3 mm cuts, or integrate an optional dewatering section for final moisture control.
Maintenance‑Minded Design Reduces Downtime
A simple drive train, centralized grease points, and tool‑less clamp bars allow daily checks to be completed in minutes, while durable media extends change‑out intervals—shifting routine maintenance from every shift to weekly walk‑arounds.
Fine‑Chemical & Pharmaceutical Powder Screening — How PK Machinery Solves It

Ultrasonic anti‑blinding up to 600 mesh
The integrated generator drives a 18 kHz wave through the screen surface, breaking surface tension so <45 µm particles can pass without clogging; screening accuracy stays above 98 % while throughput rises 1–10× versus conventional rotary sifters.
GMP / food‑grade contact construction
Optional 304 / 316 L stainless steel frames, silicone seals, and a fully enclosed cover prevent cross‑contamination and meet FDA & EU hygiene directives—ideal for active pharmaceutical ingredients, vitamins, and specialty additives.
Quick‑change multi‑deck design
One to three screening layers (400–2000 mm diameters) allow cascading cuts—e.g., 250 μm, 150 μm, 75 μm—in a single pass; tool‑less clamp rings let operators swap meshes in ≤ 15 minutes, minimising batch‑to‑batch downtime.
Low‑residue, easy‑clean ergonomics
A smooth, polished interior and centralised grease points reduce product hold‑up; no bouncing balls means no rubber fragments in the product stream, and CIP spray ports can be fitted for closed‑loop washdown.
Food‑Grade Raw Material Screening & De‑contamination

Food‑grade contact surfaces
All wetted parts can be supplied in polished 304 / 316 L stainless steel with FDA‑approved silicone seals, ensuring no metal migration or flavour carry‑over even in acidic or oily ingredients.
Ultra‑clean, dust‑tight construction
A fully enclosed cover with quick‑lock clamps and optional negative‑pressure outlet keeps airborne fines inside the machine, maintaining a clean room environment and eliminating cross‑batch contamination.
Ultrasonic anti‑blinding for sticky or electrostatic powders
An 18 kHz ultrasonic generator agitates the mesh surface, preventing screen clogging and sustaining ≥ 98 % pass rates on powders as fine as 600 mesh—ideal for cocoa, starch or milk‑powder grades that typically block conventional sifters.
Rapid multi‑deck changeovers
Tool‑free clamp rings let operators swap one‑, two‑ or three‑layer meshes in under 15 minutes, enabling single‑pass cuts (e.g., 850 µm, 425 µm, 150 µm) and slashing downtime between recipe runs.
Solid‑Waste Recycling & Resource
Recovery

No‑shaft trommel combats film wrap & sticky waste
The shaft‑less GTS drum lets lightweight bags, foil, and flexible packaging ride the full cylinder without snagging on a centre shaft.
Designed specifically “for screening material with small density, such as waste, wooden chips, activated carbon … construction material, chemical material”.
Custom apertures up to 90 mm handle mixed streams
Drums are offered in 1 – 2.5 m diameters, 1.5 – 12 m lengths, and 5 – 90 mm hole sizes, so a single screen can scalp oversize, separate 3D/2D fractions, or prepare glass cullet before optical sorting.
Self‑cleaning action minimizes downtime
As material “turns over and rolls inside the drum, stuck pieces rebound to prevent clogging,” keeping throughput stable even with damp organics or sticky films .
Heavy‑duty circular screens finish the job
YA/YK circular vibrating screens, originally built for mining, deliver 80 – 1 700 t/h at adjustable 708/755/845 rpm—ideal for final sizing of crushed glass or metal fines in recycling circuits.
The product page notes their suitability for “mining, construction, aggregates, and recycling” with robust decks and multi‑layer options.
