Introduction
The YTO series ore feeders include GD series heavy-duty apron feeders and BK series pendulum feeders, specially designed for uniform and quantitative feeding of ores and bulk materials in mineral processing plants, quarries and coal mines. They are the essential connecting equipment between ore bins and crushing/grinding systems, ensuring stable operation of the entire production line. With robust construction and precise control capabilities, YTO feeders have been widely used in mining projects worldwide.
YTO-GD Series Heavy-Duty Apron Feeders
Ideal for feeding large, abrasive and high-density materials
Core Advantages
✅Superior Heavy-Load Capacity
- Specially engineered to handle ore blocks up to 800mm and withstand impact loads over 2 tons, making it the only reliable option for primary crushing feeding
✅ Zero Blockage Design
- Interlocking chain plate structure with no gaps, preventing material jamming even when processing sticky clay-containing ores
✅Precise Variable Speed Control
- Equipped with frequency conversion drive system, feeding rate can be steplessly adjusted from 0 to 100% to match downstream equipment capacity
✅Exceptional Wear Resistance
- Chain plates made of 16-20mm thick high-manganese steel, service life up to 3-5 years under harsh conditions
✅Heavy-Duty Transmission System
- Hardened gear reducer and high-strength roller chain ensure reliable operation under continuous full-load conditions
✅Sealed Dust-Proof Structure
- Fully enclosed housing prevents dust spillage, meeting strict environmental protection requirements
Working Principles
The apron feeder consists of a driving device, head/tail sprockets, heavy-duty chains, wear-resistant trough plates and a steel frame. The motor drives the sprockets to rotate through the reducer, which in turn drives the chains and trough plates to move in a continuous loop. Materials discharged from the ore bin fall onto the trough plates and are transported forward at a controlled speed to the receiving equipment (usually jaw crushers or gyratory crushers).

Note: Customized lengths and special wear-resistant linings are available upon request
YTO-BK Series Pendulum Feeders
Ideal for quantitative feeding of fine and medium-grained materials
Core Advantages
✅ High Feeding Accuracy
- Uniform and stable feeding with error rate less than 5%, ensuring optimal grinding efficiency of ball mills
✅ Simple & Reliable Structure
- Only one moving part (the pendulum trough), with minimal failure points and easy maintenance
✅Ultra-Low Energy Consumption
- Power consumption is only 1/10 of screw feeders for the same capacity, significantly reducing operating costs
✅ Adjustable Feeding Rate
- Eccentric stroke can be easily adjusted to change feeding volume without stopping the equipment
✅ Compact Design
- Small footprint, can be directly installed under ore bins or hoppers without additional support structures
✅ Wide Material Adaptability
- Suitable for feeding various dry bulk materials with particle size less than 50mm
Working Principle
The pendulum feeder consists of a driving motor, eccentric shaft, connecting rod, pendulum trough and frame. The motor drives the eccentric shaft to rotate through a V-belt, which converts rotary motion into reciprocating linear motion of the pendulum trough via the connecting rod. As the trough moves forward, it carries a certain amount of material and discharges it at the front end; as it moves backward, the material in the bin fills the trough again. This periodic motion achieves continuous and uniform feeding.
Technical Specifications
| Model | Trough Size (mm) | Eccentric Stroke (mm) | Capacity (t/h) | Max Feed Size (mm) | Motor Power (kW) | Weight (kg) |
| YTO-BK-400 | 400×400 | 0-80 | 5-20 | 50 | 1.5 | 180 |
| YTO-BK-500 | 500×500 | 0-100 | 10-35 | 50 | 2.2 | 250 |
| YTO-BK-600 | 600×600 | 0-120 | 20-60 | 50 | 3.0 | 320 |
| YTO-BK-800 | 800×800 | 0-150 | 40-100 | 50 | 4.0 | 450 |
| YTO-BK-1000 | 1000×1000 | 0-180 | 60-150 | 50 | 5.5 | 580 |
Note: Models with automatic control systems are available for closed-loop production lines
