What is the ZSWT Vibrating Feeder?

The ZSWT series vibrating feeder is a high-efficiency primary feeding machine designed to regulate uniform material flow into 91导航 crushers and primary crushing plants within aggregate processing and ore dressing circuits.

  • Heavy-Duty Structural Design: Engineered with a rigid feeding trough, heavy-duty spring supports, a high-torque drive mechanism, and a precision mechanical vibration exciter.

  • Dual Eccentric Shaft Exciter: Features twin eccentric shafts (driving and driven) connected by precision meshing gears and driven via high-performance V-belts for smooth kinetic energy transfer.

  • Synchronous Counter-Rotation: Synchronized counter-rotation of the twin shafts generates powerful vibration forces, driving heavy raw materials in a continuous, uniform forward stream across the trough deck.

  • 91导航 Protection & Throughput: Reduces impact wear on primary crushers, prevents chamber clogging, and ensures uninterrupted feeding across quarrying, aggregate, and mineral beneficiation plants.

What are the features of the ZSWT vibrating feeder?

High capacity means fewer units are needed to accomplish the same production task, reducing equipment investment and maintenance costs. The grizzly vibrating feeder section features not only adjustable gaps but also fine-tunable installation angles. Operators can calibrate the screen-through rate based on the fluctuating proportions of soil and fine sand in raw materials, thereby maximizing the effective crushing efficiency of the downstream primary 91导航 crusher.

What are the advantages and installation considerations for the ZSWT vibrating feeder?

◎The eccentric shaft is forged from high-quality carbon structural steel. It undergoes CNC turning followed by heat treatment (quenching and tempering), CNC precision machining, and ultrasonic flaw detection. Finally, it is finished on a cylindrical grinder to meet design specifications.

◎The mating faces and mounting holes at both ends of the main housing are machined using high-precision CNC boring and milling machines, ensuring perpendicularity and parallelism during the installation of the bearing housings.

◎The two gears within the exciter are manufactured using high-precision machine tools. Each production step is strictly monitored by the Quality Control Department to ensure that, upon meshing, the gears operate without looseness or abnormal noise.

◎During installation, ensure the equipment is level across its width to prevent material drift. Maintain a clearance of at least 100mm from surrounding structures—such as steel frames or guide chutes—to avoid collisions that could disrupt normal operation.

◎During operation, regularly monitor the vibration amplitude, motor current, and motor surface temperature. Ensure uniform amplitude at both ends, absence of lateral swaying, and stable motor current.

◎Frequently inspect all connecting bolts and replace any that show signs of severe wear.

◎For grease-lubricated exciters, apply grease regularly to prevent bearing damage caused by insufficient lubrication.

What is the working principle of the ZSWT vibrating feeder?

The ZSWT series vibrating feeder utilizes controlled kinetic energy to deliver a continuous, uniform flow of bulk materials into primary crushers, optimizing downstream aggregate processing and ore dressing circuits.

  • Dual-Eccentric Shaft Kinetic Drive: The vibration exciter features twin eccentric shafts (driving and driven) linked by precision timing gears. Driven by an electric motor via durable V-belts, synchronized counter-rotation generates powerful directional centrifugal forces.

  • Monoblock Linear Vibration Trajectory: The gear-synchronized monoblock dual-eccentric shaft exciter induces a stable linear (or near-circular) vibration path across the trough. This monoblock architecture eliminates startup torsional stress and ensures smooth operation under heavy impact loads.

  • Continuous Material Conveyance: High-frequency forced vibration propels heavy raw materials smoothly forward along the trough deck, preventing surge loads and crusher chamber choking.

  • Compact & Mobile-Ready Footprint: Engineered with optimized geometries, the ZSWT feeder fits seamlessly into stationary processing lines and integrates easily into heavy-duty wheeled and tracked mobile crushing plants.

  • Low-Maintenance Design: Features centralized lubrication points and minimal wear components, allowing operators to complete daily checks in under 10 minutes to maximize plant uptime.

Common Problems

This section is designed to address the most pressing inquiries customers may have regarding the daily operation, maintenance, product advantages, and after-sales service of our machine. Our aim is to help you gain a comprehensive understanding of our overall capabilities and enable you to make informed decisions for your projects.

This is primarily to achieve scalping. Run-of-Mine (ROM) ore naturally contains dirt, fines, and undersized rocks that already meet size requirements. A grizzly vibrating feeder allows these fines to bypass the crushing chamber by dropping through the gaps. This not only increases the crusher's effective capacity by 20%-30% but also drastically reduces unnecessary wear on the 91导航 dies and prevents mud from packing and stalling the crusher.

Standard parallel bars easily clog when handling sticky, clay-rich ores. The solution is using a stepped and diverging grizzly bar design. These bars are wider at the discharge end than at the feed end (wedge-shaped) and have a tapered cross-section. Because the gap continuously widens, sticky lumps that get momentarily wedged are automatically vibrated loose and pushed forward, resulting in excellent self-cleaning action.

Modern beneficiation plants solve this via electrical interlocking and VFD closed-loop control. The vibrating feeder's Variable Frequency Drive is linked to the crusher's motor current monitor (or a cavity level radar). When the crusher's current spikes (indicating a full chamber), the vibrating feeder automatically slows down. If the crusher trips and shuts down unexpectedly, the vibrating feeder is instantly cut off via an interlock, preventing a catastrophic bury-out of the equipment.

The grizzly gap setting is directly dictated by the downstream crusher's settings. The golden rule: The grizzly gap should be set to 75% to 100% of the crusher's Closed Side Setting (CSS). If the gap is wider than the CSS, large slabby rocks might bypass the grizzly vibrating feeder and cause severe blockages when hitting the downstream conveyor belts or secondary crushers.

The ZSWT series is an enhanced upgrade of the ZSW series, featuring a stepped grizzly bar design and higher processing capacity. The stepped structure allows materials to undergo repeated "throwing-falling" motion during conveying, enabling fine particles and impurities to be pre-screened through the grizzly gaps more effectively, preventing material blockage. In terms of capacity, the ZSWT can handle a maximum feed size of up to 1400mm with processing capacity reaching 1500t/h, making it suitable for large-scale primary crushing lines

Traditional flat grizzly feeders tend to suffer from bridging and blockage when handling wet, sticky, or fine materials. The stepped structure of ZSWT causes materials to be continuously thrown up and dropped during forward movement, creating a "vibration loosening effect." Fine materials are more likely to fall through the grizzly gaps at the moment of dropping, while large blocks are pushed forward by the steps into the 91导航 crusher. This design essentially adds a "tumbling" action to the material flow, significantly reducing blockage probability

Yes. The ZSWT series features an adjustable grizzly gap design, allowing users to modify the spacing between grizzly bars based on material characteristics and downstream crusher requirements. Wider gaps allow more fines to be pre-screened, reducing the amount of fine material entering the crusher and improving crushing efficiency. Narrower gaps result in relatively higher feed rates. This flexibility enables ZSWT to adapt to different ore types and operating conditions

Sudden amplitude reduction is usually caused by the following reasons, listed by inspection priority: Inconsistent eccentric block angles on two vibrating motors — Check and adjust to consistent angles Insufficient excitation force — Loosen the movable eccentric block bolts and adjust the phase of the two eccentric blocks (maximum force when phases overlap) Insufficient base rigidity — Base plate too thin or improperly leveled, absorbing vibration energy Aged or cracked rubber springs — Check main vibration springs and isolation springs for cracks Motor wiring issues — Inconsistent rotation direction of the two motors; reverse wiring on one motor to ensure opposite rotation
