West River Conveyors designs transfer chutes to improve material flow when conveying a variety of products, including standalone transfer chutes and chutes attached to a discharge boom.

Designs range from simple containers to more complex systems. We can also design transfer chutes for multiple heights and angles. Our team of engineers will work with you to evaluate your needs and design a chute for your exact requirements.

West River designs and tests transfer chutes in the most demanding underground applications.

Transfer chutes often must be enclosed to prevent spillage and the entry of airborne dust when moving product from one conveyor line to another line to another.

Our chutes are highly effective at protecting their contents and containing them to the flow stream. A transfer chute routinely contains material that’s heavy, sharp or abrasive, so it needs to be lined with a very tough plate.

Common plate options include:

  • Ceramic
  • Stainless steel
  • Abrasion-resistant (AR)

Stainless and AR plate liners can be bolted or welded into the transfer chute’s frame, providing customers with the option of replacing the liners when needed.

Transfer stations often have a rock box, which is a lip around the bottom of the chute that provides a ledge for rocks and dust to collect. The purpose of a rock box is to prevent the flow of ore from wearing out the bottom of the transfer chute.

Transfer Chutes Overview

Transfer chutes are primarily used at the transfer points in a conveyor system. Therefore, they need some type of feature such as a rounded base that will allow the chute to discharge its load into a centralized stream in the same direction as the receiving conveyor.

The simplest conveyor system with a transfer point consists of two conveyors. Ore comes from a draw point such as a bin or stockpile. The first conveyor transports the ore to the transfer chute which will transfer it to the second conveyor. This type of transfer chute typically has no moving parts, but it must place its contents in the center of the belt. Failure to do so can result in spillage that will need to be picked up.

Conveyor systems become more complex when they use variable paths requiring multiple chutes, which usually requires a greater vertical distance.

These systems divide the material with multiple diverted discharge points, which an operator can control with butterfly valves. The design of the cross section is particularly important for switchable transfer chutes, since blockages are more likely than with simpler chutes.

Furthermore, packing becomes a more serious concern for longer chutes due to the greater difficulty in cleaning them and preparing them for operation.

Rock Boxes

A rock box directs the flow of ore so that it lands in the center of the conveyor belt each time. It must also prevent the ore from damaging or wearing out the bottom of the transfer chute, which could change the trajectory of the ore. The rock box allows the rock on top of it to absorb the abrasion caused by the moving ore.

However, a rock box can’t prevent ore from hitting the side of the transfer chute before it reaches the rock box. This problem is generally the result of differences in the size of rocks and the speed of the feeder belt, which alters the ore trajectory and causes the ore to hit the chute in different locations.

Liners

AR liners are made from steel with a high carbon content, which increases its hardness. However, the carbon also makes the liner much more difficult to weld, so they’re usually bolted in place. We utilize UHMW liners fastened to the inside of the chute as additional protection.

One of the advantages of bolts is that they provide an indication that the liner is wearing out. The bolt heads protrude from the surface of the liner, causing them to wear out first. The bolt will fall out when this occurs, thus alerting an operator to replace the liner before the transfer chute becomes damaged.

Multiple missing bolts along the conveyor path could indicate that a liner has fallen out, which is a considerably more serious problem than a liner that’s merely worn. A loose liner can damage the conveyor belt or plug a chute, so it needs to be located immediately.

Skirting

The chute skirting is a seal between the chute and the conveyor belt, primarily for the purpose of preventing material from bouncing and rolling off the belt during loading.

The skirting is made of rubber and runs completely around the edge of the chute except for a discharge point. It’s an area of high wear because neither the belt nor the skirt can have lubrication on them.

The operator should continually monitor the skirt’s condition and adjust it as needed to prolong its lifespan and this adjustment is critical for the chute to operate properly.

Skirting that’s too loose will result in product spillage while adjusting the skirting too tightly results in faster wear.

Transfer chutes typically have multiple safeguards to help keep a conveyor system operating. These safeguards address issues of equipment failure and operator error, both of which are common causes of conveyor system outages.
