The Pendulum Feeder manufactured by Zhengzhou Zhenggang Machinery Co., Ltd. is a volumetric feeding machine designed for stable, continuous, and uniform feeding of granular materials from storage bins or hoppers to receiving equipment. It is commonly used in mining, ore dressing plants, chemical processing, coal handling, cement production, grinding lines, and crushing systems.
This mining pendulum feeder is especially suitable for feeding ore and mineral materials into ball mills, jaw crushers, cone crushers, conveyors, and material mixing systems. The machine uses a motor, reducer, eccentric wheel, connecting rod, and pendulum plate to create a controlled reciprocating motion. By adjusting the eccentric wheel position, the feeding amount and speed can be controlled according to production requirements. With simple structure, low energy consumption, smooth operation, low noise, adjustable feeding capacity, and convenient maintenance, the Pendulum Feeder is an ideal feeding solution for mineral processing plants and small to medium-capacity production lines.
The pendulum motion provides continuous and controlled material discharge, helping ball mills, crushers, and conveyors operate more smoothly.
The feeding amount can be adjusted by changing the eccentric wheel position, allowing better control of material flow in grinding and crushing systems.
The compact mechanical transmission system requires low motor power, reducing operating cost for continuous feeding applications.
The feeder has a practical structure with fewer complex parts, making installation, operation, cleaning, and maintenance easier.
Balanced reciprocating movement reduces vibration and noise, supporting stable performance in ore processing and industrial material handling lines.
Key parts are made from high-quality steel with wear-resistant treatment, improving service life under regular feeding conditions.

Used in ore dressing plants to feed mineral particles evenly into ball mills, helping maintain stable grinding performance and continuous mill operation

Suitable for feeding non-sticky ore, minerals, limestone particles, and granular materials into jaw crushers, cone crushers, or other crushing equipment.

Applied in beneficiation production lines for controlled feeding of iron ore, copper ore, gold ore, and other mineral materials before grinding or separation.

Installed under storage bins or hoppers to discharge materials evenly and prevent unstable feeding caused by irregular material flow.

Used in cement plants, coal handling systems, and industrial production lines for feeding small block or granular bulk materials into downstream equipment.

Suitable for chemical processing and mixing systems requiring controlled feeding of non-sticky granules and small particle materials with adjustable flow rate.

The Pendulum Feeder is used for uniform and controlled feeding of ore, mineral particles, granules, and non-sticky bulk materials from storage bins or hoppers to ball mills, crushers, conveyors, and mixing systems.
The capacity range is approximately 1–45 TPH, depending on the selected model, feed opening size, material properties, and required feeding amount.
It is suitable for non-sticky granular materials, ore particles, mineral materials, coal particles, cement materials, and small bulk materials with particle size generally below 50 mm.
The feeding amount can be adjusted by changing the eccentric wheel position, which controls the pendulum stroke and material discharge rate.
The Pendulum Feeder is not recommended for sticky materials or very fine powdery materials because they may cause clogging. It performs best with dry, loose, non-sticky granular materials.
Silver Ore Grinding Plant • Bolivia
The Pendulum Feeder gives our grinding line steady and controlled ore feeding. It works well under the storage hopper, feeds material evenly into the ball mill, and helps keep the whole mineral processing system stable with very simple maintenance.
