Conveyor transfer chute is an important part of bulk material conveying equipment. When there is a problem with the transfer chute, it will directly lead to the progress of the entire material delivery, which will seriously lead to shutdown.

Conveyor chutes are used in many industries to transport bulk materials from one conveyor belt to another.

The correct design of the conveying chute can ensure effective material transmission without clogging. It can also minimize the wear of chute and belt.

The following are considerations for the design of conveyor chutes.

What is a transfer chute?

The conveying chute is mainly used as the conveying point in the conveying system to transport from high place to low place. It is mainly used in open pit mines and is often used in tandem with the pass. The application of chute generally adopts 45 ° inclination, which can also be changed according to demand. When conveying materials larger than 3mm, the inner wall of the chute shall be provided with lining plates or thickened plates.

5 Precautions

The following problems may occur in the conveyor transfer chute:

  • l The chute is worn
  • l Blockage or accumulation
  • l Belt deviation
  • l Dust spillage
  • l Wear resistance

The correct design of chute can improve the conveying efficiency. Here are some precautions.

Conveyor direction and angle

The conveying chute is used to move the transported materials to the conveyor belts in different directions. When designing the conveying chute, it is necessary to consider that the material is transported from the upper part to the conveyor belt in different directions.

Here, the in-line conveyor is relatively easy to design, and its inlet and outlet are in the same direction.

Determine the horizontal spacing of the chute. In order to reduce material overflow, the width of the output band should be wide enough for the input bandwidth.

Material properties

The characteristics of transported materials directly affect the transportation of chute. The density of the material will cause the chute to be blocked. Therefore, on the premise of material treatment, the tendency of material decomposition, separation and dust release shall be considered.

Materials will produce certain dust during transportation, which will cause environmental pollution, and it needs to be cleaned regularly. In addition, the material will also cause wear on the inside of the chute when falling. Therefore, the chute needs to be lined in the design to extend the service life of the conveying chute.


The conveying chute limits the throughput of the conveying system. When designing the chute, it is necessary to consider the weight and volume of boring conveying per hour to ensure adequate capacity.

At the input end, the speed of the conveyor determines the path of material descent. At the bottom, the size and shape of the chute shall be designed to convey materials to the discharge belt at a speed close to the belt speed. This will reduce belt wear and increase the motor load of the differential.


The speed of the horizontal outlet is determined by the falling distance of the conveying chute. Set the material conveying speed according to the distance so that it can fall onto the conveyor correctly.

You can reduce the effective drop height by adding an intermediate ledge or step in the chute. When materials accumulate in these areas, it will absorb the impact of falling materials, thus reducing wear in the chute.

The more materials fall into the chute, the more debris will be generated and the more dust will be released.

Conveying chutes are used in many industries, such as ore industry. Improper design will lead to the shutdown of the entire conveying system, and will also cause a significant loss of productivity.

During the design, carefully observe the characteristics of materials, and consider these factors in advance to avoid losses.
