Diabolo Shot Blasting Machine

Diabolo type shot blasting machines are designed for descaling, derusting of steel cylinder, steel tube, pipe, round bar and all kinds of round work-pieces. Make it show metal color , increase its ratio surface area and improve the anti-fatigue force and anti-rust capacity of surface, improve the inherent quality of surface and prolong the lifetime.

A diabolo system transports work-pieces through blasting machine while rotating, the coverage of work-pieces is assured. It is also easy to integrate into any production line for the next process such as: welding, coating, etc. One machine is designed to process work-pieces with different diameters. A cross load, unload system is available to load, unload work-pieces from diabolo, which rises speed and saves labor cost.

Key Features of Diabolo Shot Blasting Machine

Blast Turbines

☆Dynamic Simulation Design

The liners form a round track for abrasive, which allows all abrasive leave the turbine when they reach the highest speed with the least internal bounce and self-wear. Can offer high blast speed and full abrasive cover.

The maximum thickness of blast wheel shell can reach 70mm, better sealing effect, long service time.

The interior of the blasting wheel is turbo type, abrasive will not not stay in the distributor. Abrasive utilization rate increased to 99%, improve efficiency by 30%.
Blast wheel bottom has cushioning rubber, which can reduce vibration.

☆Blade & Impeller

The material of impeller is 40CrMnMo, the material of blade is high chrome wear-resistant casting iron, the hardness can reach HRC60-65.

Blasting Chamber

☆ Working principle

The engineering team uses 3-D dynamic simulation design blast turbines layout to ensure that the steel shot ray can cover the surface of the workpiece 360 degrees.

☆10 Years Warranty

Shot blasting chamber with Mn13 steel guard plate which has high impact toughness and high service life, fully realize the reflection function of abrasive and improve the cleaning quality. We promise 10 years maintenance-free warranty to blasting chamber.

☆High sealing performance

3+ layers of sealing curtain in inlet, outlet opening and between chambers. The curtain layers are natural rubber material with leaf spring which can automatically reset, that prevent the abrasive spatter out during the blasting and ensure the safe.

Dust Collector

Max 3-grade dust collecting design can achieve max 99% clean efficiency.

☆Level-1 Dust Collecting

A gravity settling box above inlet/outlet chamber will make the abrasive shot in airflow drop back to chamber, so the dust collecting filter will not be damaged by abrasive shot, can achieve a longer service time.

☆Level-2 Dust Collecting

Cyclone dust collector have 2 collection points for dust and debris, primary collection point is for heavier chips and debris, while the second point is for finer particulate matter.

☆Level-3 Dust Collecting

High filtering average cartridge type or venturi design bag type filter can offer a long service time high filterability effect, the final cleaning efficiency is upto 99%.
