Turnkey system handles alternative fuel
supplies
Portasilo has recently completed the proving trials for a meat and bonemeal storage and handling system at the Castle Cement Ribblesdale Works.
Portasilo has recently completed the proving trials for a meat and bonemeal (MBM) storage and handling system for Castle Cement for the company's Ribblesdale Works The meat and bonemeal is used as an alternative fuel to reduce coal consumption at the cement works and is produced as a byproduct from meal rendering processes

The decision by Lafarge Aggregates to bring a major piece of equipment back into operation gave engineering company Ace Arc the opportunity to use all its welding and fabrication expertise.
Conveyor cleaner wins in long-term test
In trials conducted at British Energy's Eggborough Power Station, Ace Arc's Dirt Whacker was found to be a most durable and effective conveyor belt cleaner.
The material is very difficult to handle, particularly in pneumatic conveying systems.
The high fat content can lead to smearing and buildup in pipelines.
The system supplied included a large site built storage silo to store approximately 240 tonnes of MBM.
A land based blower for offloading tanks was provided with dehumidification and chilling system.
The flat bottomed silo was fitted with a screw extractor, which transferred product into a Portasilo loss in weight feeder, which provided gravimetric discharge between 1 and 7t/h.
This loss in weight feeder has been specially developed for cohesive products and incorporates a vertical agitator, and screw discharge.
MBM is also prone to self-heating in storage, hence the silo was fitted with a Portasilo developed monitoring package and fire protection system.
This comprises carbon monoxide detection combined with multipoint temperature sensors and an inert gas deluge in the event that combustion is detected.
A pneumatic conveying system transfers MBM to Castle Cement's Calciner through a 125mm diameter pipeline.
Again, the blower is dehumidified and chilled.
Portasilo's package was a turnkey system including extensive civil works, wiring and controls.
After the successful commissioning and proving trials of the MBM system at the Ribblesdale Works, Castle Cement has now placed a second order for a similar system for its works at Ketton.
This will transfer MBM to two kilns, but is otherwise similar to the Ribblesdale Works.
