Container Unloading

For over 20 years Kockums have been involved with supplying container unloading systems, and in more recent times the potential of utilizing standard ISO freight containers for storage and shipping of bulk solids has been more recognized. The handling of bulk powders such as flour, magnesium oxide, fly ash, cement, and many others have been limited by the difficulty of retrieving the powders, which compact and consolidate.

When handling products in shipping containers there are two fundamental concepts. Either the use of dedicated purpose-built containers or utilising standard ISO freight containers. In either case tipping of the container has always been seen as necessary and acceptable, but flow may only be guaranteed if the powder is fluidised by mechanical or more preferably by aeration techniques.

Purpose-built containers are a significant investment and limited in general freight usage as they may not be off hired. These containers are usually dedicated to a specific supply, and returned to source empty. The benefit of these containers is that they are designed specifically for an application including all the necessary in-built product flow devices and rigid discharge connections, and therefore without the on-going consumable costs.

When utilising standard ISO freight containers a polyethylene container liner, cardboard bulkheads and a fluidising system (Kockumat) must be installed each time to provide a central discharge point and to promote product flow. These items are normally priced for single use, and are disposable or recyclable. (There is no return to source necessary). The Kockumat is commercially available through a third party. Please call for details.

Kockums Bulk Systems focus is on the actual conveying equipment and we have developed the KTV75 “Suck and Blow” conveying vessel. This conveying system, based on Dense Phase technology was primarily designed for this application but over time many other uses have been revealed. The KTV75 is connected to both the containers bulk head and destination silo infeed line; the container is then tipped, the product is fluidised and then with vacuum assistance the conveying vessel is filled. Once full, conventional positive pressure Dense Phase Conveying is utilised to transfer the product to the destination(s). This cycle repeats until the container is empty. Conveying rates of 20-30 tonnes/hr are achievable with this system and larger bespoke systems capable of up to 60 tonnes per hour have also been supplied.

 

Features/Benefits:

  • 20-30 tonnes per hour
  • Skid Mounted for mobility
  • Heavy duty design to AS1210
  • Ideal for rugged environments like the Mining and Cement Industries
  • Ideal for abrasive products
  • A wide range of valve options
