Using a Vacuum System to Remove Abrasive

A high efficiency vacuum system can collect abrasive quickly and easily from wherever it is in the tank.

Cleaning up the tank after the blasting is complete to remove all the spent abrasive can be the most time consuming part. If you have to remove the abrasive out of a tank manually with a broom and shovel you will spend many hours and labor is costly. All that spent abrasive must be removed out of the tank before you can move on to the next stage of the job. Any residue left will spoil the coating. It will be a long, tedious clean-up and therefore a long time before you can paint.

If you are able to use a high efficiency vacuum system you will be able to collect the abrasive quickly and easily from wherever it is in the tank, and dump the abrasive via the storage hopper into bulk bags or directly into a waste skip so it is easily handled and disposed of.

Yes, these projects call for an efficient vacuum system that can suck up spent used abrasives and collect it at a central point ready for recycling or disposal.

The Vacuload™ 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 Vacuload™ 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 Vacuload™ 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 the required amount of compressed air is not available.

The Vacuload™ 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 the cleaned air exits to atmosphere.

A complete vacuum recovery system is made by combining a Vacuload™ Module with a suitably sized Interceptor Storage Unit and the pick up tool to suit your application.

How do the Vacuload™ Recovery Systems work?

All Vacuload™ System models work using the same operating principle.

  1. The operator sucks up spent abrasive and the abrasive and air mixture travels along the vacuum hose or pipe to the Interceptor Storage Module.
  2. The Interceptor slows the air/abrasive mixture down such that all particles and heavy dusts drop out of the air stream and are stored for recycling or disposal. Light dusts remain entrained in the air stream and are carried along a hose to the Vacuload™ Module.
  3. At the Vacuload™ Module all dusts are removed by final filtration cartridges in the dust collector (the cake of dust which builds up on the cartridges is dislodged by an automatic reverse pulse and is collected in a hopper awaiting disposal). Clean air carries on through to the vacuum pump and then discharged to atmosphere.
