The production of 3 vehicle loading cascade systems to be used for loading pet coke is coming to a close following FAT inspection by our client. These consist of a 900 sized system for loading at rates up to 450TPH, with 2 further identical 1100 systems for higher rates reaching up to 880TPH throughput.
Each design is similar with respect to the setup of the system. A fixed head chute is utilised featuring cascading cones for material control to protect from degradation and dust generation, the cones are enclosed by a shroud encapsulating dust laden air preventing its escape to the surrounding environment. Finally, a skirt is installed at the chute outlet point creating a seal with the material pile during loading operations.
The 900 sized system has a fully extended length of 5.61m and achieves a retracted non-operational height of 2.5m For the 1100 sized system, the fully extended length is 6.05m and allows full retraction to 3.0m.
Ceramic tiling is the wear liner of choice within the head chute and cones. This provides sufficient abrasion resistance without impeding material flow and gives increased longevity to the wear surfaces.
With the material to be loaded being pet coke, a complex wiring and electrical specification had to be adhered to. The hazardous area classification for the chutes was specified as NEC Class II Div 1, Group F. With this in mind, all electrical components had to be sourced such that they are suitable for operation within the potentially explosive environment.
Shown in the gallery below, you can view images of the systems in our workshops. This is where all pre-installation and any pre-commissioning checks such as trial fits of components take place.
