Vacuum load your blast pot

17 Ways to Blast a Tank

On some blasting projects you have to move your spent abrasive from A to B. From ships hulls, from inside tanks or from bridge containments, sometimes you just can’t use a wheelbarrow and shovel. The process needs to be quick and efficient.

The time you spend loading a blast pot can be back-breaking work or if you are manually loading with a forklift, you have to sling a bulk bag or small bags up over the top of your blast pot, which can use two operators and extra equipment to load the blast pot.

These projects call for an efficient vacuum system that can recover spent used abrasives and collect it at a central point ready for recycling or disposal.

By vacuum loading the blast pot while the blasters are out having morning tea or lunch, one operator can vacuum load the blast pot without even having to leave the ground. Once the unit is installed it is a simple matter of turning a few ball valves to allow the operator to vacuum the abrasive straight out of the bulk bag, tanker truck, or straight from the floor when recycling, and load it straight into your bulk blaster.

This can result in saving you:

  1. intensive/ back breaking labour and risk of OH&S claims
  2. having extra equipment on site
  3. needing multiple workers for manual labour
  4. stopping the blasting operation because you have run out of abrasive
  5. a lot of time
Vac Loading
Vacuum Loading

Vacuum loading is a safe, practical and economical way to work and is powered by compressed air. It is a worthwhile addition to any Bulk Blast System. No more lifting heavy bulk bags full of blast media to load your Mega-Blaster™ - simply fill it safely with abrasive from ground level minimising your downtime and eliminating those tiresome waits for the crane to arrive. It will now take just seconds to switch the compressed air supply from the blasting supply over to the vacuum supply and commence loading.

The compressed air powered Blast-One EductorTM venturi-vacuum loading system is mounted onto the frame of the MegaBlasterTM and has a loading capability of over four tonnes per hour.

For fast recovery of used Abrasives

The VaculoadTM systems have been specially designed for blasting sites and for handling abrasive. The series 2 and 4 models are powered by compressed air which saves you the cost of another expensive motor (when you have finished blasting simply switch your compressed air lines from your Blast machines to your VaculoadTM system and you’re in Recovery mode).

The vacuum is generated by a specially designed, air powered Eductor pump that is inexpensive, efficient and requires very little maintenance. The larger VaculoadTM models generate vacuum using a Trilobe Positive Displacement Blower which is powered by a diesel engine or large electric motor. These units are suitable for projects where large volumes of compressed air are not available.

The VaculoadTM module is a compact skid mounted unit which combines the vacuum generating source with a high efficiency dust collector. This ensures that all dusty and contaminated air from vacuuming is filtered and only clean air exits to atmosphere.

A complete vacuum recovery system is made by combining a Vacuload™ Module and a suitably sized Interceptor Storage Unit. Even just the transfer lid with the pick up tool and hopper may suit your application. See below.
