Lipu Trough Feeder, also known as a chute feeder or reciprocating feeder, delivers lump and granular materials from a hopper or ore bin to downstream equipment at a controlled, steady rate. It is commonly installed ahead of jaw crushers, impact crushers, screens, belt conveyors, and mineral processing equipment.
A trough feeder is a mechanical reciprocating feeder designed for short-distance, controlled material transfer. It uses a reciprocating trough to move material from a storage bin or receiving hopper to the next processing stage.
It is suitable for non-sticky lump and granular materials. For fine powders, highly sticky materials, or applications requiring high-precision dosing, a different feeder type should be selected.
Material enters the feed trough from a hopper or storage bin. The drive mechanism moves the trough back and forth through an eccentric mechanism and connecting rod.
During the forward stroke, friction carries the material toward the discharge end. During the return stroke, the trough moves back beneath the material, preparing for the next feed cycle. This repeated reciprocating motion provides a continuous and controlled material flow to downstream equipment.
A Lipu Trough Feeder typically includes:
The trough carries the material, while the drive system generates the reciprocating motion required for stable feeding.
Trough Feeders are widely used in:
Lipu Trough Feeders can handle a range of non-sticky bulk materials, including:
| Model | Discharge Opening (W × H, mm) | Max. Feeding Size (mm) | Feeding Capacity (t/h) | Motor Power (kW) | Weight (kg) |
|---|---|---|---|---|---|
| 600 × 500 | 600 × 500 | 200 | 5–10 | 4 | 1,045 |
| 1240 × 980 | 1240 × 980 | 350 | 10–30 | 7.5 | 1,710 |
Capacity may vary according to material size, bulk density, moisture content, and site conditions. Contact Lipu for model selection and customized configuration.

Frequently Asked Questions
What materials can a trough feeder handle?
Trough feeders are suitable for lump and granular materials such as ore, coal, limestone, gravel, and aggregate. They are not recommended for sticky materials or fine powder.
Where is a trough feeder normally installed?
It is commonly installed below an ore bin, hopper, or storage silo to feed a jaw crusher, impact crusher, screen, conveyor, or other receiving equipment.
Can the feeding capacity be adjusted?
Yes. Capacity can be adjusted by selecting the appropriate model, trough size, discharge opening, and operating conditions.
Is a trough feeder suitable for a jaw crusher?
Yes. A trough feeder is commonly used to provide steady, controlled feed to a jaw crusher in mining and aggregate processing plants.
Can Lipu customize the feeder?
Yes. Lipu can customize the trough dimensions, discharge opening, liner configuration, drive arrangement, and mounting method to suit your process requirements.
We provide a variety of mining and processing equipment, including feeders, rock crushers, grinders, classifying and screening machines, washing machines, gravity separators, flotation machines, magnetic separators, electric separators, dewatering equipment and laboratory mineral processing equipment.
