Chain bucket elevator is a continuous conveying machine for vertically lifting materials, which is suitable for conveying from low to high. Scoop up the material from the low end to the top through the hopper, then turn it over and pour it into the material tank.

The bucket elevator conveyor uses a series of hoppers fixed on the traction chain or belt to conveying bulk materials upward in the vertical or near vertical direction.

The conveying speed can be adjusted according to the conveying volume, and the conveying height can be selected as needed.

what is the bucket elevator?

The bucket elevator composed of hoppers, drives, top or bottom rollers, tapes, tensioning devices, casings, etc , which is widely used in cement plant, coal, limestone and other fields. 

When using bucket elevator, it will bring a lot of convenience. And the main features are as follows:

  • Vertical conveying material; the structural of the bucket elevator was simple and there are many characteristics of the bucket elevator, such as easy maintenance, stable operation and wide application range, etc.
  • Adopt inflow feed; The driving power is small, and there is almost no material return or excavation during material lifting.
  • Wide promotion range; It is suitable for powdery, small particle materials and materials with high grinding ability.
  • Less environmental pollution; Dust pollution is reduced during conveying.
  • Stable operation, high reliability and long service life.

classification of the chain bucket elevator?

 According to the characteristics of the material ,which an be divided into three types : chain, plate chain and belt.

  • The chain bucket elevator has simple structure and large self weight.

The connection with the hopper is firm, the material with high grinding property is conveying, and the wear of the chain is small.

  • The plate chain bucket elevator has firm structure and light self weight. It is suitable for materials with large lifting capacity, but the joint is easy to be worn.
  • The belt bucket elevator has simple structure, it is not suitable for conveying the material with high grinding property.

According to the speed of hopper operation, bucket elevator can be divided into three forms: centrifugal unloading, gravity unloading and mixed unloading.

  • The bucket speed of centrifugal unloading is fast, which is suitable for conveying powdery, granular, small block and other materials with small grinding and chipping.
  • The bucket speed of gravity unloading is slow, which is suitable for conveying massive, high specific gravity and high grinding materials, such as limestone, clinker, etc.

When to consider replacing the bucket elevator?

How to judge whether the bucket elevator needs to be replaced , which can be analyzed according to the following points:

  • Lower production efficiency and affects profits

Inefficient work may lead to many problems. Replacing bucket elevator can effectively improve production efficiency and reduce cost

  • Wear or damage

The wear of bucket elevator is one of the reasons to consider replacing bucket elevator.

The wear or damage of bucket elevator may be due to long-term use, conveying corrosive materials and no maintenance.

  • Downtime

when the machine does not operate for a long time, the mechanism will have problems

  • Maintenance costs gradually increase

Common issues and how to maintain the chain conveyor elevator?

The following common problems and solutions will appear when the bucket elevator is in use.

Hopper belt slipping

Feeding of less materials;

Untie the hopper belt joint, which means that the tensioning device is in a tensioned but not tensioned state;

Increase the friction between the hopper belt and the transmission shaft;

Too much material returned:

According to the conveying materials, appropriately reduce the speed of the hopper to avoid excessive return;

Timely adjust the discharge tongue of the machine head;

Hopper falling off

Feed evenly to avoid excessive materials;

  Adjust the position of the feed port.

Hopper belt torn:

Install steel wire mesh at the feed inlet to avoid excessive material entering.

Hopper belt deviation: 

Check and make sure that the rotating shafts of the head wheel and the bottom wheel are on the same plane.
