Apron feeder is a heavy-duty conveyor designed to feed large lumps of ore and aggregate to downstream equipment. It has strong structure, smooth operation, uniform feeding (usually adopts frequency control system so as to adjust the operating speed, control the feeding volume and reduce the phenomenon of blockage), and it is the commonly used equipment in heavy load feeding and conveying system.
CAFU Machinery's apron feeder works as follows:
Our apron feeder is mainly divided into frame, crawler chain assembly (below), support rollers (sealed for life and self-lubricating), transmission system (including electric or hydraulic drive) and other components.
The grooved head sprocket is driven by an electric motor and reducer to move the crawler chain, which engages with the sprocket to pull the crawler chain track assembly with the material forward at a certain speed. The load carrying mechanism (support rollers) is rotated by the friction of the crawler chain track and carries the weight of the material and the running part. The frame, on the other hand, carries the entire weight of the machine and transfers it through the frame to the base of the machine.
The material is fed into the feeder from a hopper (or pit) located above the rear section of the apron feeder and moves forward through the crawler track assembly until it is discharged at the head.
For example, our CF1052 Apron Feeder is designed as a light-duty machine with a 20m3 feed hopper, which can transport limestone, ore and other materials with a particle size of not more than 600mm and a bulk density of 1.6t/m³ in use. It consists of a frame, crawler track assembly, support rollers, transmission system and other components.
The apron feeder requires minimal maintenance due to its tracked design. All components are 'sealed for life' and 'self-lubricating', requiring virtually no maintenance. This ensures that our customers enjoy long-term reliability and minimal downtime.
The 20m3 hopper liner is robustly constructed from wear resistant steel.
In practice, the apron feeder has several advantages. It provides better feed control for downstream equipment and prevents clogging; it absorbs the impact of material loaded directly onto the feeder, especially in shallow layers; and it is flexible in its application, recovering dry or wet material of any size at a uniform rate. In addition, its crawler chain track uses a track and roller design similar to that used in bulldozers and excavators, with polyurethane seals in the rollers to prevent the ingress of abrasive materials, making the slat feeder easy to operate and maintain and extending its service life.
In addition, the apron feeder can be installed not only horizontally, but also on an incline (usually not more than 20 degrees), which saves overall space and offers a number of other benefits and features. However, there are certain requirements and specifications (as outlined in the Apron Feeder Installation Guide) that must be followed when installing and using the apron feeder to ensure proper operation and performance.
