Product Introduction: Reciprocating coal feeder is a professional quantitative feeding equipment widely used in mines, coal mines, thermal power plants and aggregate production lines. Main models include K series and GLW series. Adopting crank-link reciprocating transmission structure, the machine delivers stable, uniform and continuous material feeding for coal, ore and granular materials. Compared with vibrating feeders, it features smoother feeding, low dust, strong impact resistance and no material blocking. It is suitable for underground explosion-proof and heavy-duty open-pit working conditions, serving as essential silo steady-flow feeding equipment for mining production lines.

Working Principle

The motor and reducer drive the crank-link mechanism, which pushes the tank bottom plate to perform regular reciprocating movement. When the plate moves forward, it pushes materials out stably through friction and inertia. When returning, materials fall naturally from the silo without backflow. Continuous circulation realizes stable and uniform feeding. The feeding capacity can be precisely adjusted by changing the stroke length or adopting variable frequency speed regulation, effectively avoiding material rushing, accumulation and intermittent feeding, ensuring stable operation of the entire production line.

Core Advantages

1. Stable & Adjustable Feeding Capacity

Mechanical reciprocating pushing ensures steady flow without pulse fluctuation, achieving high feeding accuracy. Both manual and frequency conversion adjustment methods are available to match different production capacities and perfectly coordinate with crushing, screening and conveying equipment.

2. Heavy-Duty & Impact Resistant

Reinforced frame, thickened wear-resistant bottom plate and high-strength crank-link structure enable the machine to withstand heavy impact from lump coal and large ore. It is not easy to deform or damage, adapting to long-term high-intensity heavy-duty mining conditions.

3. Low Dust & Low Noise

Fully enclosed structure with no violent vibration during operation reduces dust and noise pollution significantly. Explosion-proof motor configuration is optional to meet underground coal mine and flammable workshop safety standards.

4. Simple Structure & Low Maintenance Cost

Mature and reliable transmission structure with low failure rate and few vulnerable parts. Easy disassembly, inspection and cleaning. Daily maintenance only requires regular lubrication, greatly reducing operation and downtime costs.

5. Compact Installation & Strong Compatibility

Low body height and small floor space, easy to install and hang under silos and hoppers. Customizable gates, hoppers and speed control systems are available for new production line matching and old plant renovation.
