Applications

1.Automotive
2.Iron, steel and metal foundries
3.Heat treat operations
4.Forging operations
5.Small stamping parts manufacturers

Features and Benefits

The barrel blast machine(roto drum blast machine) adopt a unique drum shaking structure, the drum not only rotating but also shake up and down within a narrow scope during shot blasting process, so the small to medium size workpieces can be completely stirred to achieve the blasting process popurse.
1. Efficient, uniform blast cleaning effect
2. Thin pieces and small special pieces can also be properly handled
Single piece barrel design that eliminates pinch points, so this kind of shot blasting unit can process the thin and small workpieces.
3.Simple maintenance and maintenance
Fully welded construction with abrasive resistant steel in bottom and sloped walls where blast media flows, so greatly shorten the downtime.
4.Adjustable drum angles with shock loading suspension (easily modify tumbling
dynamics)
5. point drum support (Better stability- durability)
6.Abrasion Resistant (AR) screws (longer life)
7. Machine can be fully automated (higher productivity)

8.Leak resistant piece door (maintenance advantages)

9.Canted vanes available for wider blast pattern (better cleaning/shorter cycle times)

Superior design, quality and rugged construction make the Qinggong Barrel Blast Machine (Roto Drum blasting machine) more reliable and easy to maintain. Qinggong offers a variety of different machines, designed for your specific needs.

Blast turbines

★Cantilever centrifugal high efficiency blast wheel, can operate clockwise or counter-clockwise, optimum abrasive flow rate for faster cleaning.

★impeller adopted #40 Chrome wear resistant cast iron.

★High chrome wear resistant cast iron for blades, control cage, abrasive distributor.

★Dynamic and static balance.

★Blades of impeller weight tolerance≤±1.5g.

★Unbalanced torque tolerance≤±7.5Nmm.

★Direct drive blast wheel with special motor bearings means less spare parts, less noise, energy-efficient, large abrasive flow rate and good cleaning effect ,etc. advantages.

★Machined housing ensures proper alignment of all internal parts.

★Less part wear due to greater concentricity and more precise alignment.

★Safety interlock is fitted on the housing cover to protect the workers safety.

★Particular guard liner structure increase the abrasion resistant lifespan 60% to 200%.

Pneumatic Abrasive dosing units

★Patented pneumatic control abrasive gate valve, which depend on cylinder to control stroke so as to control the blast wheel in long-distance. This avoids motor burned, blast wheel jammed, shot idling blast and people injured caused by common abrasive control valve closure lax

★Abrasive flow is indicated at the ammeter at the electrical switch and control box.

★Adjusting the bolt on the abrasive control valve can conveniently adjust the abrasive flow rate to an required amount

★In order to be able to dismount the abrasive control unit from the silo for repair works and to avoid any abrasive outflow for each unit one manual slide is installed in front of the abrasive control unit.

Abrasive cleaner

Our patented abrasive cleaner is applied for recycling shot/grit, which is to ensures high quality blasted surface and munimal abrasive shot. As the abrasive is so durable it is able to be recycled hundreds of times, resulting in an extremely low abrasive breakdwon rate.

Critical to achieving this efficiency is the effectiveness of the abrasive recycling plant. Poorly designed or manufactured abrasive recycling systems will not correctly recycle the abrasive and are unable to maintain the correct abrasive working mix.

Our patented abrasive separator consists of an extended rotary separator drum that will totally remove all big clumps including big wast, scrap and paint chips etc. The abrasive is then fed through a gravity air wash separator where all dust, degraded abrasive and waste is drawn out of hte good abrasive by an air current.

Only good, correctly sized abrasive is fed back to the abrasive storage hopper and blast pots for recycling.

Our patented abrasive cleaner ensures maximum recyling rates of the abrasive and high quality surface finishing is achieved.
