Difference Between the Apron Feeders and Belt Feeders
Apron feeders are best suited to primary applications. Wherever there is likely to be big heavy material with sharp edges that may be dropped from a height, apron feeders will always be the better choice in this situation. This also applies to uses such as bark, mulch, or recycling that are prone to slip on top of a belt.
Belt feeders are much better for secondary applications, they are typically used for material no larger than 6” and are not suited for impact, larger material, and heavy loads as well as Apron Feeders.
Belt Feeders can carry material longer distances than Apron Feeders. They also operate at faster speeds than Apron Feeders because high rates can cause accelerated wear on Apron Feeders, however, come with the added cost of servicing regularly and are much more prone to damage.
Apron Feeders vs Belt Feeders
Apron feeder and belt feeder are two common types of feeders used in various industrial applications, such as mining, quarrying, and construction. Both feeders are designed to feed bulk material from one process to another, but there are some differences between the two that make them more suitable for different scenarios.
An apron feeder, also known as a plate feeder, is a heavy-duty feeder that consists of a series of overlapping steel plates or pans that are mounted on chains with rollers. The plates or pans are typically made of steel and can range in thickness from 10 to 50mm, depending on the application.
The apron feeder is designed to handle heavy and abrasive materials, such as large rocks and ore, as well as sticky materials that tend to cling to the pan surface. It can deliver material at a rate of up to 5,000 tons per hour and can handle lumps up to 2,000 mm in size.
The main advantage of the apron feeder is its ability to handle heavy materials without the risk of material spillage or blockage. The overlapping design of the pans ensures that the material is contained within the feeder, preventing it from spilling out. In addition, the heavy-duty construction of the feeder makes it more durable and resistant to wear and tear, which is essential in harsh and abrasive environments.
On the other hand, the main disadvantage of the apron feeder is its higher initial cost compared to the belt feeder. Due to its heavy-duty construction and assembly, the apron feeder requires more time and resources to install, maintain, and repair.
A belt feeder, also known as a conveyor belt feeder, is a conveyor that involves a rubber belt that is driven by a series of pulleys. The belt is typically flat and can be made of various materials, such as rubber, PVC, or nylon. The belt can carry materials ranging in size from fine powders to heavy and bulky items.
The belt feeder is designed to handle a wide range of materials, such as sand, gravel, coal, and grain. It can deliver material at a rate of up to 1,000 tons per hour and can handle lumps up to 150 mm in size.
The main advantage of the belt feeder is its lower initial cost compared to the apron feeder. The design of the belt feeder is less complex and requires less time and resources to install, maintain, and repair. In addition, the rubber belt is more flexible and can adapt to changes in the material flow, reducing the risk of material spillage or blockage.
On the other hand, the main disadvantage of the belt feeder is its limitation in handling heavy and abrasive materials. The rubber belt is not as durable and resistant to wear and tear as the steel pans of the apron feeder. This makes the belt feeder less suitable for harsh and abrasive environments.
At the end of the day, the decision between the two lies in the specific application and what the needs of your quarry are.
