A: There are a number of reasons a chute can block, including:
- Poor chute design (including tiling specs, chute shape, belt loading, spoon discharge angle).
- Inappropriate transfer design. For example, the clearances are not correct, the flow surface angles could be incorrect, or the side width may be too narrow.
- The chute design is not suitable for the properties of the material it is handling.
- The wear liner is not correct for the application
- The outlet belt stopping time is shorter than incoming belt stopping time
A regularly blocked chute can be a source of downtime or production delays (with the whole plant sometimes having to stop to fix the blockage), spillage, unnecessary hosing and other headaches.
Chute Technology can provide an engineering check, or full process audit to find the cause of the blockage, and present a range of solutions.
A: In most cases, the need to hose and spray chutes can be avoided with a correct design, which can avoid blockages, dust generation and spillage.
Chutes may require some hosing occasionally – typically on maintenance or shutdown days, which provide a good opportunity to inspect the condition of the wear liners and carry out general chute maintenance.
However, if you are hosing to clean spillage, you may be wasting both time and money. A correctly designed chute does not cause spillage. If you are finding that you are continuously spraying material to improve flowability through a chute, you may need an engineering check or transfer audit to determine what’s causing these flow or spillage problems.
A: In most cases, Chute Technology has proven that skirtboards systems can be avoided if the chute is designed correctly.
A: Spillage and wear can be controlled if the belt profile along the skirts is subject to minimal sag and vertical travel. Sag can vary depending on conveyor tension, material load on the belt and idlers/transition arrangement.

A: No. With correct chute design, Chute Technology has totally eliminated spillage from transfer points and entire materials handling systems. As long as the plant is operating within design guidelines, you should not experience any spillage.
If you’re seeing spillage in your system, we can conduct an audit to determine the cause and suggest solutions.
A: The time interval between wear liner replacements varies depending on wear liner selection, chute design, site operating conditions (such as throughput or start and stop trajectories) and material properties (such as type, density, shape, size, moisture and cohesion). Chute Technology can inspect and test your transfer system to investigate the possibility of increasing the time interval between liner replacement.
Chute Technology can also provide an audit of your current chute to determine how to improve material flow and reduce wear.
A: Yes! In fact, in many cases, premature conveyor belt wear is caused by an inefficient chute design. Redesigning the chute can extend the belt life considerable (up to 12 times in projects Chute Technology has been involved in).
A: Loading of a conveyor belt has to be in line with the belt direction. If the material coming from the chute is not in line with the belt, this will cause tracking issues and off-centre loading of the receiving conveyor. It can also cause spillage and premature wear of skirtboards.
A: It varies depending on the material, throughput and other factors (such as impact angles, impact pressures, drop heights and material speed), but all chutes will experience a natural amount of wear over time.
If areas of your chute are wearing out prematurely or you would like to extend the life of your assets, a different tiling solution or improvement of design may be needed to save downtime and repair costs.
A: Premature tile failure can be caused by a number of factors such as:
- Chute Design (incident angles, drop height, heat, impact pressure)
- Structural Design (chute wall flexibility, exceeding deflection criteria, thermal expansion, inadequate or absent structural analysis)
- Operating Environment (shock start loads, shock starts impact angles, water quenching events, tramp material impact)
- Materials (actual loads exceed capability, manufacturing source, manufacturing quality, specifications not suited for application)
- Maintenance (fails between inspections, poor repair standards)
Chute Technology can provide a consultation to determine the cause of tile failure and recommend solutions to solve it. To arrange a site visit, call 1300 833 140.
