Cleveland Cascades to supply shiploading system to Cuba

Cleveland Cascades is to supply its cascade loading system to Cuba where it will load cement and clinker. The project is focused on supporting the elimination of dust generation during loading operations for which the materials are known to be problematic.

The system is to be supplied with a fixed head chute and an independent upper deflector which has the capability to pivot –5°. This feature allows for greater optimization of material control before the product enters the head chute.

The 950 sized Cleveland Cascades cones are to be utilized on the project; these have the capability of loading up to 750m3 per hour.

The extended length of the system will be 22.0m measuring from the interface flange to the base of the skirted outlet with an operational retracted length of 6m.

Due to the abrasive nature of the materials being loaded, the head chute will feature chromium carbide liners as this is the initial point of impact following the deflector meaning improved abrasion resistance is required. The cones will have ceramic tiling installed as opposed to chromium carbide liners, this reduces the static load of the system whilst still providing sufficient wear resistance.

A full suite of electrical components is to be included to allow for system automation and safety.

At the customer’s request this system will have the option to easily retrofit a hatch charger if deemed necessary for future loading operations. This requires careful design consideration when producing the specification for the hoist unit to ensure there are no complications with regards to the additional weight which would be introduced to the system.

Kinder Australia Pty Ltd’s solutions have eliminated problem with conveyor systems at a basalt quarry.

A long-standing quarry customer needed to find a solution that would: v eliminate belt cleaning and carryback issues; v address conveyor belt mistracking; v address the issue of increased maintenance and cleaning-up costs; and v minimize production downtime.

Located in North Western Victoria, the quarry customer has been a long time vocal advocate for Kinder Australia conveyor componentry solutions. Major productivity and operational improvements at the quarry have been realized in recent years with the installation of K-Commander® Self Centring Idler to address the on-site belt tracking and excessive material spillage issues.

K-MotorShield Motor Covers were also recently installed to the site. Cost savings due to reduced maintenance and extension of motor life were achieved. K-Sure® Support Belt Support Systems installed also delivered on its promise of consistent and stable support at the quarry’s main transfer points.

The quarry was utilizing a primary belt cleaner and it was observed by Maintenance Teams particularly during the Winter months that material fines were travelling down the conveyor belt. This residual material or carryback had the tendency to cling onto the belt and accumulate on the return rollers. This common scenario was a leading contributor of potential belt mistracking issues and increased power usage on site.

In-depth consultations with quarry and Kinder Technical Applications Team were aimed at addressing the important belt cleaning challenges as this greatly impacts the site’s continuous productivity goal. Reducing maintenance and cleaning costs associated with time and resources required to clear/shovel away the material fines on a regular basis was also targeted.

For many years, the quarry was operating an incline conveyor system. To implement a reliable and effective cleaning system and overcome the sites ongoing challenges, key factors needed to be taken into consideration, including the hard to reach tail pulley location and tilting nature of the incline conveyor.

Maintenance Team were unanimously in favour of installing K-Rotabrush® conveyor belt cleaner, that has the capacity to provide excellent cleaning performance primarily where space limitations apply.

K-Rotabrush® conveyor belt cleaners installed at the quarry, consisted of a rubber brush design and featured a high performance, uniform rotatory action successfully sweeping excessive fines off the belt. This greatly reduced the instances of carry back on the return rollers and helped to stabilize belt tracking, improved conveyor operation and plant efficiency. K-Rotabrush® effectively per formed the cleaning action without compro mising belt wear and extending its wear life. An external contractor was involved in this simple belt cleaner installation and to date minimal maintenance and virtually no adjustments have been necessary.

As well as resolving the ongo ing belt cleaning challenges, the quarry was also successful in achieving a multi tude of improve ments and plant efficiencies due to the K-Rotabrush® conveyor belt cleaner installation. Including the imme diate eliminat ion of carryback issues and the extension of belt wear life — all thanks to correct conveyor belt tracking.

Costly cleaning up expenses and the risk of injury has also been signif icantly reduced.

Quarry Mainte nance Teams continue to report less production down-time with operators being more efficient, less time involved with manual shovelling of material fines has meant more time to focus on other daily duties.

Part of a National building and construction materials group, Kinder is pleased that the Maintenance Team continues to spread its successes achieved to date with other members of the group at training sessions and operational improvement meetings.

RESULTS: v improved belt cleaning and carry back issues; v improved conveyor belt tracking; v reduction in maintenance cleaning up costs; v daily continuous productivity maintained; and v sharing of successes with group members.
