Working Principle

The core power source of the ZSW vibrating feeder consists of two counter-rotating synchronous eccentric vibrating motors. The synchronous rotation of these motors generates a directional, constant linear excitation force, driving the feed trough to perform small-amplitude reciprocating linear vibrations.

After material is fed into the trough, it slides forward at a uniform speed along the trough surface under the action of vibration inertia. Simultaneously, the front-end bar screen separates the material, separating and discharging fine powder and soil through the gaps in the screen, while larger, qualified materials are continuously conveyed to the crusher's feed inlet.

High-elasticity rubber shock-absorbing springs at the bottom isolate vibration from transmission to the frame and the ground, preventing overall machine resonance. The equipped frequency converter control cabinet allows adjustment of the motor's excitation frequency, free control of the feeding speed and hourly throughput, and supports interlocking start/stop with the downstream crusher, achieving automated, unmanned feeding.

Core Component Structure Description

1.Dual Synchronous Eccentric Vibrating Motors:

The main power unit of the machine, with dual motors operating synchronously in opposite directions, ensuring balanced and stable vibration force; high protection level against water and dust, suitable for open-air, dusty, and humid mining conditions.

2.Heavy-Duty Feed Hopper + Wear-Resistant Bar Screen:

Thickened wear-resistant steel plate welded hopper, integrated bar screen at the feed end, removable wear-resistant lining inside the hopper, combining conveying and pre-screening functions; the lining can be replaced individually after wear, without replacing the entire hopper.

3.Imported High-Elasticity Rubber Shock Absorbing Springs:

High tensile strength imported rubber material, excellent elasticity, high load-bearing capacity, absorbs vibration and impact, reduces operating noise, and extends the service life of the frame and civil engineering foundation.

4.Independent Variable Frequency Electrical Control System:

Equipped with a dedicated electrical control cabinet, stepless speed regulation of 0–100% feed flow rate, supports linkage control of upstream and downstream crushing equipment, and has a high degree of automation.

5.Optional Dustproof Sealing Cover:

Fully enclosed arc-shaped dust cover, preventing dust diffusion during conveying, meeting the environmental protection production requirements of green mining.

1) Uniform and Controllable Feeding, Wide Capacity Coverage:

Dual synchronous eccentric vibration output provides stable excitation force, ensuring uniform material movement without spurting, interruption, or stockpiling. Combined with variable frequency electronic control, the feed rate is infinitely adjustable, increasing the conveying capacity by 1.5–3 times compared to older models with the same trough size, suitable for high-capacity continuous crushing operations.

2) Pre-screening and Desliming Reduces Crushing Losses:

An integrated wear-resistant bar grid at the feed end pre-separates stone powder, soil, and fine aggregates, feeding only large pieces of material into the crusher, reducing wear on the crusher liners, improving the purity of the finished aggregate, and lowering the overall energy consumption of the production line.

3) Significant Energy Savings and Lower Operating Costs:

Optimized mechanical vibration structure reduces overall power consumption by more than 45% compared to plate feeders; no chain or roller friction losses, only a few vulnerable parts, resulting in a significant reduction in long-term electricity and consumable maintenance costs.

4) Modular design for simple and convenient maintenance:

The entire machine is modularly disassembled, allowing for individual removal and replacement of the excitation motor, shock-absorbing springs, and wear-resistant trough liners. The excitation unit features a long-lasting, maintenance-free lubrication structure, requiring only periodic simple grease application. An optional motor temperature sensor module can monitor equipment status in real time, enabling predictive maintenance.

5) Heavy-duty reinforced trough for impact resistance and durability:

The trough is constructed from thickened, high-strength, wear-resistant steel plates, welded as a whole, with added reinforcing ribs in stress concentration areas. Removable wear-resistant liners inside the trough can withstand continuous impact from large, high-hardness materials such as granite, basalt, and iron ore, supporting 24-hour continuous heavy-load operation without deformation.

6) Low installation threshold and minimal infrastructure investment:

The low center of gravity and horizontal layout result in a low-profile machine, eliminating the need for deep foundation excavation or the construction of elevated conveying platforms. The entire machine can be directly hoisted and placed on a flat base for installation, significantly shortening the construction period and reducing civil engineering costs.

7) Vibration and noise reduction, environmentally friendly:

Equipped with high-elasticity imported rubber shock-absorbing springs, it isolates vibration from the plant foundation, resulting in low overall operating noise. An optional fully enclosed dust cover effectively suppresses dust leakage, meeting national mining environmental emission standards.

8) Versatile for all scenarios, highly compatible:

Suitable for fixed sand and gravel production lines, mobile crushing plants, metal ore beneficiation, construction waste recycling, calcium carbonate powder processing, road ballast production, and other scenarios. It can be integrated with jaw crushers, cone crushers, impact crushers, triaxial elliptical vibrating screens, and ultrafine grinding mills.
