A typical spinner hanger type shot blasting machine includes following major parts:

Loading & Unloading Device
I type shot blasting machine is equipped with one hook. That is a simplex working mechanism, suitable to heavy work piece.
Y type shot blasting machine is equipped with two hooks. That will increase processing efficiency. One batch of workpiece will be loaded outside while another batch is being processed in the machine at same time.
Each hook has rotation device, that will ensure abrasive covers workpiece for all directions completely.
Workpiece on hook is usually transported on overhead rail manually.
As an option, workpiece can be taken into blasting chamber by feeding device from door automatically.
Automatic transport facility can be even equipped over whole overhead rail.
Carrying hook is also available with integrated chain hoist for operational ease and safety.
Large workpiece will be hang on hook directly, small workpiece will be hang on special tool.

Blasting Chamber
Blasting chamber housing is made of wear-resistant steel plate.
Manganese steel guard plate is equipped in blasting chamber.
Excellent material with high toughness is durable enough to guarantee long service life.

Blast Wheel
Blast wheel is key part of shot blasting machine.
Blade & Impeller are made of high hardness material to get long service life.
With dynamic dimulation design, abrasive stream will leave the turbine with high speed and best direction to cover more surfaces of workpiece.
That allows for short treatment time, high performance and a superior blast process.

Abrasive Cycle System
Abrasive cycle system includes crosswise screw conveyor, bucket elevator, separator, abrasive silo, etc.
That works coordinately with blast wheel to keep dynamic balance.
Used abrasive and fines fall on crosswise screw conveyor by abrasive collection hopper under the blast chamber and then are delivered to bucket elevator bottom.
Bucket elevator lifts it up to separator.
In separator, used abrasive is separated from fines and contaminants by screen filtering and ventilation filtering, and returned to the abrasive silo.
From abrasive silo, that will be distributed to blast wheel and reused for blasting.

Dust Collection Device
Fan sucks dust into dust collection device.
Dust will be collected by gravity and other dust collector.
That will keep abrasive tidy and guarantee dust does not pollute environment.

Electric Control Unit
Electric control unit is brain of shot blasting machine, including PLC, touch screen, etc.
That will control all units working coordinately and stops machine if any emergency happens.
Machine can work on manual mode or automatic mode.
All components are international famous brand or China top brand.

Working Principle:
① Hang workpiece on hook or tool. Then workpiece enters into blasting chamber. Close door.
② Blast wheel gives angular hit of abrasive to rotating workpiece. Meanwhile, abrasive cycle system keeps delivering abrasive from chamber bottom to blast wheel. And dust collection device keeps separating dust from used abrasive to make it clean.
③ When set time is up, all devices stop working. Open door. Hook inside moves out and unload workpiece.
④ Another processing period starts from step 1.
