ADPLUS XHD Vibrating Screen
Extra Heavy Duty
ADPLUS XHD Vibrating Screen
While the standard ADplus vibrating screen remains a benchmark for reliability and efficiency, the XHD (Extra Heavy-Duty) series is engineered for operations demanding maximum resilience. We’ve taken the foundational DNA of the ADplus and ruggedized the entire chassis to withstand harsher environments and higher tonnage.
Beyond structural reinforcement, the XHD series introduces an optimized deck dynamics system. This drastically improves material stratification, ensuring finer particles settle faster and pass through the screen efficiently, ultimately boosting your plant’s overall throughput and product purity.
When you choose the XHD series, you aren’t sacrificing the proven efficiency of the standard ADplus—you’re amplifying it. The XHD series bridges the gap between high performance and extreme durability.
Innovative Centrifugal Counter Weight Assembly
This innovative feature eliminates excessive resonance motion when the screen is starting or stopping. At start-up, the counter weight assemblies have a small “mass x radius” value. This means that they accelerate to operating speeds with a smaller driving torque and drive motor than for a conventional vibrating screen with fixed counter weight.
Screen Drive
The driving pulley may be fitted to either side without disturbing the shaft. This means that the drive can be positioned to suit the installation. Depending on the screen size, two or four ‘C’ section v-belts are required for the drive.
Guards
There are fully enclosed steel plate guards over the counter weight assemblies. They are easily removable to allow inspection or maintenance of the counter weights or mechanism.
Screen Body
Structural strength of the screen body is enhanced by bending the entire top length of the screen body. This crucial features prevents horizontal warping of the screen side plates. Enabling this well-reinforced screen body to have long life without additional weight. Vertical stiffening angle irons add additional rigidity to the side plates.
Rubber Buffer Strips
Self-clamping, wear resistant rubber buffer strips are fitted to the screen frame mesh supports and prevent metal-to-metal contact. This cushioning increase screening media wear life.
Feed Box & Discharge Spouts
A feed box absorbs the impact of incoming material, reduces wear on the screening media and makes more effective use of the screen’s deck area. A feed box with replaceable liners is fitted to all screens.
Discharge spout simplify the installation of chutes. Discharge spouts with replaceable liners are standard on all screens.
Flexible Back Plate Cover
Every ADPLUS vibrating screen is fitted with a flexible rubber back plate cover above each deck. This allows inspection and removal of the screening media.
Reliable FAG Bearings
The FAG self-aligning, double row, spherical roller bearings were developed specifically for vibrating screens. To eliminate locking of the bearing to the shaft (which leads to premature failure), the inner rings of the bearings have self-lubricating sleeves. The bearings are protected from dust and dirt by grease-purged labyrinth seals. Grease lubrication is standard for all ADPLUS vibrating screens.
Self-Enclosed Bearing Cartridge
The load-carrying roller bearings in the vibrating mechanism, together with their mounting cartridges and cover, can be assembled in the dust-free atmosphere of a workshop and fitted to the screen in the field as a complete unit. This means the bearings are not exposed to dust particles during assembly and can be relied on for their rated lifetime.
Maximised Stratification & Screening Efficiency
Every ADPLUS XHD vibrating screen is designed to operate up to 4.5G. The high energy of 4.5G aggressively throws the material bed into the air, creating a looser, more fluid state. This rapid dilation of the material bed allows fines to drop to the bottom of the payload instantly, drastically improving screening efficiency and accuracy.
Side Plates Secured with Huck Bolts
Every ADPLUS XHD vibrating screen is designed to operate up to 4.5G. Conventional nuts and bolts (even with lock washers or nylon inserts) frequently fail under continuous high G-forces as the vibration overcomes the thread friction. A single loose fastener on a side plate redistributes stress to neighboring bolts, causing a rapid domino-effect failure across the screen box. Because there are no threads to strip or back off, Huck bolts cannot vibrate loose. They maintain their precise clamp force indefinitely.
Twin Shaft Exciter Design
For larger ADPLUS XHD vibrating screens, a twin-shaft exciter design is incorporated. The most significant benefit of a twin-shaft design is its ability to produce a purely linear (elliptical-to-straight) stroke profile. This creates a distinct, straight-line throwing action, typically oriented at a 45 degree angle to the screen deck. This linear motion forcefully lifts material up and forward, ensuring uniform travel speed from the feed end all the way to the discharge end, preventing material from blindingly or plugging on the deck.
Polyurethane Wear Liners
In vibrating screens, the main shaft housing and deck cross members are critical structural zones. Because they sit directly beneath or within the material flow, they are subjected to relentless abrasive wear, high-impact forces, and severe structural stress.
Upgrading these components from bare steel or traditional rubber to polyurethane (PU) wear liners offers significant mechanical and operational advantages.
