In tumble-blast batch processing machines, all surfaces of components are exposed to impact treatment as the parts gently turn over and over in a slowly rotating tilted basket.

The Guyson design virtually eliminates component damage due to part-on-part impingement that is so common with “barrel-blast” machines. Our tilted basket generates greater circulation of components in the batch, which not only yields more thorough and uniform coverage, but also makes for a shorter blast cycle – typically five minutes or less!

In this 40 × 40-inch machine, one or two suction-blast guns are positioned over the mouth of the removable perforated steel basket to cover the batch of small components as they turn over. The working load capacity is approximately one-third cubic foot or 55 pounds of components. Various basket perforation sizes, coated baskets and mini-baskets for very small batches are available.

The rotation speed of the basket is adjustable, according to the tumbling behavior of different parts. At the end of the timed blast cycle, an automatic air wash blow-off cycle removes media and dust from the parts. An optional front discharge chute speeds and eases unloading.
