Everything You Need To Know About Apron Feeders


Apron feeds are crucial from a crusher’s perspective to swiftly and efficiently process materials. These powerful instruments significantly increase the crusher’s overall performance and lifespan and assist with the movement of raw materials. In this article, we’ll explore the significant part apron feeders play in the realm of crushers. View more on their composition, advantages, and maintenance from the standpoint of the crusher.

Different kinds of Apron Feeders

The two main kinds of apron feeders are:

Heavy-Duty Apron Feeders

Heavy-duty apron feeders are designed for very difficult tasks, such as excavating and transporting a lot of material. They can transport heavy, rough things over great distances because of their large, powerful pans and ropes.

Light-Duty Apron Feeders

For chores that don’t need a lot of power, including farming and small-scale company operations, light-duty apron feeders are ideal. Because their pans and chains are smaller, they typically handle lighter materials.

What Makes Apron Feeders So Important?

1. Ensuring a constant supply of materials

Crushers need a continuous supply of raw materials in order to operate effectively. Apron feeders are excellent at handling this crucial task. They ensure that material continues to enter the body of the crusher from various sources, such as stacks or main crushers. The breaker operates more efficiently and has less downtime because of this steady supply.

2. Refraining from material bridging

Crushers often encounter the issue of material bridging. Large pieces of the material get caught at this point, halting the breaking process. Because they are durable and capable of handling heavy materials, apron feeders prevent items from becoming trapped. These large pieces are broken up by their pans and chains, which also make sure that the feed to the crusher is level and smooth.

3. Precise control over feed rate

To achieve the desired end product size and quality, various crushers may need various feed rates. Apron feeders enable employees precise feed rate control, allowing them to alter and enhance material flow. This is particularly useful when handling objects of various sizes and shapes.

4. Protecting the Crusher

Breakers are better shielded from harm by apron feeds. They absorb the weight of large and heavy items, extending the life of the crusher’s components. This will increase the breaker’s overall efficiency and income since it will last longer and need less maintenance.

Apron Feeder Components

The apron pans are where materials initially make contact with the crusher, seen from its perspective. These pans are designed to withstand the abrasiveness of the materials, so they are strong and lasting. They transfer items fast onto the breaker’s belt system.

Conveyor Chains or Rollers

One of the most important components of managing the flow of materials is the chain or wheels that move the apron pans. They ensure that materials are supplied to the crusher on a regular and regulated basis, which aids in maintaining the crusher’s peak performance.

Drive System

The driving mechanism, which is often an electric motor, causes the apron hopper to move. The reliability of this system is crucial from the standpoint of the crusher since any power outages might halt the flow of materials and make it challenging for the crusher to operate.

Tensioning System

In order for the conveyor to operate smoothly and effectively, the chain must be under the proper amount of tension. The material flow may be slowed down and the crusher may sustain damage if the chains are not sufficiently tightened.

Maintaining the Apron Feeders

Taking care of apron feeds ensures that the crusher continues to operate as well as that they last longer. The following are a few of the most crucial crusher repairs:

Regular Inspection

It’s critical to regularly inspect the apron pans, chains, and closures. If issues are identified and resolved as soon as feasible, unanticipated downtime may be avoided.


It’s crucial to properly oil the chain, rollers, and bearings in order to lessen wear and friction and ensure that the apron feeder functions effectively.


By keeping the apron pans clear of material buildup and clean, you can prevent them from becoming clogged and maintain a consistent flow of material into the crusher.

Chain Tension

The chain tension should be monitored and adjusted as necessary to prevent it from slipping or becoming overly tight, which might halt the flow of materials.

Replacement Parts

Maintain a supply of necessary replacement parts to minimize crusher downtime in the event that the apron feeder malfunctions unexpectedly.


Apron feeders are a crusher’s best parts since they guarantee that materials enter the grinding chamber effectively and smoothly. It is impossible to overstate how crucial they are for keeping materials circulating, preventing clogging, and safeguarding the breaker. For the crusher and apron feeder to function effectively together, proper maintenance and care of the apron feeders are required. Over time, this will increase the performance and productivity of the crusher.
