Cement Handling Problem Solved for Safe Maker

Spiroflow Solves Cement Handling Problem for Security Products

Access Security Products Ltd. is a leading manufacturer and supplier of burglary and fire resistant safes, vaults and physical security equipment. The company uses an expensive proprietary cement mixture in the walls of their safes and vaults rendering them almost impenetrable to thieves and fire.

The material is a fine powder, which arrives by container quite compacted, has very poor flow characteristics, bridges easily, is very abrasive and readily absorbs moisture. The cement is packaged in twenty 2,000lb/ 900kg single trip, single loop, lined bulk bags which must be emptied into a large outdoor storage silo.

Access Security had initially purchased a $ 40,000 pneumatic conveying system from another supplier but the cement material accumulated within the conveying tube rendering the conveyor completely inoperable. After working with the vendor for some time without resolution, Access Security ultimately had no other choice but to scrap the equipment and find an alternative conveying solution.

System requirements

  • Provide a completely closed robust system that could reliably convey their cement material without material build up and excessive wear on equipment.
  • Accommodate bulk bag unloading inside the company’s warehouse but convey the product through the roof, outside the building and into a large outdoor storage silo at distance of 12m.
  • Operate reliably and consistently in temperature and weather extremes typical in the Ontario, Canada region.
  • Provide a dust-free solution to minimize exposure to moisture in the environment and to provide a clean and safe work environment for employees.
  • Successfully unload the 900kg single loop, lined, single trip bulk bags within 30 minutes or less.
  • Incorporate appropriate discharge aids to encourage material flow: side massage, bottom massage and agitation.
  • Offer proof that the recommended solution will work before purchase.

Materials Testing

Due to the characteristics of the particular cement mixture and the frustration the customer had previously experienced, Spiroflow experts recommended that it be tested in the company’s test lab.
President Peter Gauthier commented, ‘Having our cement powder thoroughly tested was a vital step in the process. It gave us confidence that Spiroflow’s recommended solution would work as specified.’ Additionally, Spiroflow has long guaranteed any powder handling solution tested in their lab. ‘The company’s performance guarantee also gave us piece of mind,’ added Gauthier.

The new Spiroflow unloader installed at Skretting of Longridge, Lancashire, UK, has enabled an increase of productivity. Discharging bulk bags is 4 to 5 times faster then before. Skretting of Longridge, Lancashire, UK, a fish food manufacturer, had an ingredients handling system installed over 8 years ago by a specialist contractor who had included a simple bulk bag unloading arrangement which feed ingredients into an Aero Mechanical Conveyor. Requirements # The Aero Mechanical Conveyor lifts ingredients up to a horizontal screw conveyor feeding storage bunkers on the floor above. # It was the ‘simple’ bulk bag unloading arrangement that proved to be the bottleneck in the production process and the cause of constant frustration to operators. # Comprising just a lidded hopper with a spigot, where the neck of the bulk bag was attached, the simple bulk bag unloading arrangement required the a fork lift truck for the duration of discharge because there was no other means to support the bag. # In addition, an operator had to be on standby to aid the flow of poor flowing or compacted products.

Reducing material breakage with a tube conveyor system
A good solution to reducing material breakage is a gentle conveying system. Low-speed, high-volume movement will slowly push the material along without too many contact points and no impact forces. In many industries, the integrity of the materials or products being conveyed is of utmost importance. This is especially true in the food processing industry, where materials are particularly fragile, and breakage can lead to many negative consequences. However, even though preserving material integrity is crucial during the conveying process, no less than 29% of industrial facilities state that material breakage is one of the top three conveying challenges they face on a daily basis. Material breakage Material breakage is defined as the separation of material particles into two or more pieces under the action of stress. Any place where the product or raw material is sliding against a conveyor surface (be it a tube, flat surface, or any other) can cause material abrasion and possibly material breakage. Breakage generally leads to a decrease in product value. In the food industry, even the smallest amount of breakage can lead to lost product, sanitation issues,
