WL Series Vibrating Feeder Introduction
The WL Series Vibrating Feeder is engineered for uniform and continuous feeding of bulk and granular materials from hoppers to crushers, screens, or conveyors. Utilizing eccentric shaft vibration technology combined with a belt-driven flywheel system, it ensures stable, automated material flow with adjustable feed rates. Equipped with a variable speed motor and advanced gear oil lubrication, the WL Series delivers reliable, low-maintenance operation in demanding mining, quarrying, and industrial environments.

Product Overview: WL Series High-Performance Vibrating Feeder
The WL Series Vibrating Feeder is a robust, precision-engineered solution for controlled material handling in crushing and screening circuits. Its adjustable amplitude and speed control, heavy-duty construction, and advanced lubrication system make it ideal for maintaining consistent feed rates, preventing hopper bridging, and optimizing downstream equipment performance across various industries.
Key Features of the WL Series Vibrating Feeder
1. Consistent & Controllable Material Dosing
Powered by an eccentric shaft on a belt-driven flywheel, the feeder generates a strong, linear vibration that ensures uniform material discharge from storage hoppers, preventing flow interruptions and optimizing crusher or screen efficiency.
2. Flexible Feed Rate Control with Speed Regulation
Operators can adjust feeding capacity through mechanical amplitude adjustment (via counterweights/eccentric blocks) and stepless speed control using a variable frequency drive (VFD), allowing precise matching to process requirements and material characteristics.
3. Robust Construction with Extended Bearing Life
The feeder features a heavy-duty frame and a CNC-machined bearing pedestal for perfect alignment. An advanced gear oil lubrication system provides superior cooling and protection for bearings, significantly extending service life in high-load, high-temperature conditions.
4. High Reliability & Low Maintenance Design
Built for continuous operation with minimal downtime, the WL Series offers easy access to components for inspection and maintenance. Its simple mechanical design and efficient lubrication reduce wear and operational costs while maximizing equipment availability.
5. Compact Footprint & Wide Industrial Applicability
With a space-saving design, the feeder integrates easily into new or existing plant layouts. It handles a broad range of materials—from large blasted rock to fine aggregates—in mining, metallurgy, cement, quarrying, and chemical processing applications.
Applications of the WL Series Vibrating Feeder
1. Primary Crushing Feed in Quarries & Mines
Delivers consistent, controlled feed of blasted rock or run-of-mine ore to jaw crushers or gyratory crushers, optimizing throughput and reducing equipment stress.
2. Secondary & Tertiary Feed in Aggregate Plants
Supplies screened or crushed material to cone crushers, impact crushers, or screening units, maintaining steady process flow and product consistency.
3. Cement & Industrial Raw Material Handling
Feeds limestone, clay, gypsum, and additives to crushers, mills, or prehomogenization stacks in cement and mineral processing plants.
4. Recycling & C&D Waste Processing
Controls the feeding of demolition concrete, asphalt, and rubble to crushers or sorting systems in recycling facilities.
5. Bulk Material Handling in Ports & Terminals
Used for unloading or transferring coal, ore, aggregates, and granular bulk materials between conveyors, hoppers, and processing equipment.
