General Introduction

Apron feeder / Apron conveyors is a type of mechanical material handling equipment used in bulk material handling systems. It consists of a series of horizontally mounted overlapping metal plates or pans that are typically connected to heavy-duty chains or cables. The pans move along the feed bed and carry materials such as ore, coal, rock, and aggregates from a hopper or bin to a processing or transport system. Apron feeders are used in mining, quarrying, and industrial operations, where a large quantity of heavy or abrasive materials needs to be moved. They are particularly effective for feeding and controlling the flow of bulky, wet, or sticky materials, which can cause blockages and other disruptions in other types of feeders. Apron feeders come in different sizes, capacities, and configurations, depending on the specific application requirements. They can be designed for a range of operating conditions, including extreme temperatures, high-impact loads, and corrosive environments. Some apron feeders may also come with hydraulic or electrical control systems to optimize material flow and reduce wear and tear on the feeder and downstream equipment.

MAIN APPLICATIONS

Crusher feeding
One machine covers full range of materials (cement, iron ore, sand, coal, limestone, fertilizers and so on.) Unloading of material of any size range, size up to 1,500 mm. Suitable for a wide variety of abrasive materials. Each unit is tailor-made to suit crusher.

Wagon unloading

Receive mine material directly from dump trucks. Unloading of multiple trucks at once. Suitable for unloading in combination with other transportation equipment. High impact load resistance.

Hopper discharge

Pan of width up to 3,000 mm suitable for large block materials. Vertical or even negative angle walls for extremely sticky materials. Reasonable pan shape design for better cleaning

Stockpile discharge

Several short apron feeders in series. Unlimited on the height of material stockpile. Heavy duty design ensures reliable material extraction.

Apron Feeder Category

Light-duty apron feeder: continuous feeding machine, suitable for short-distance conveying of bulk materials with a particle size of less than 160mm.

Medium-duty apron feeder: It is a uniform intermittent feeding equipment, and it is an apron feeder for larger pieces and medium-density materials.

Heavy-duty apron feeder: It is suitable for continuous and uniform feeding from storage bins to crushers, conveyors, etc., and short-distance conveyance of materials with high density and large lumps.

FEATURES

1. Standard heavy-duty ribbed pans prevent excessive deflection under high-impact loading & severely abrasive working conditions.
2. Cast segmental track chain bolted to heavy steel hubs keyed to oversized front drive shaft.
3. Standard crawler-type under carriage parts have a long service life.
4. Rugged steel support frame with impact rails to limit pans deflection, thus eliminating permanent bending of the pans.
5. The heavy-duty design delivers high availability, ease of operation, low maintenance and operational costs and greater profits.
