Airless Tunnel Type Shot Blasting Machine Manufacturer and Supplier
To Descale Mild Steel Plate & Structural Section Prior To Painting
"PCS" has a range of Airless Shot Blasting Machine Tunnel Type with number of Blast Wheels varying acording to the production output required.This is the most used after & the most flourishing series for the long structural, channels, angles, plates, gratings, pipes etc. for large production output in terms of surface treatment.
The opening of the tunnel and numbers of blast wheels, depend upon the structure of the job for attaining homogenious finish.
Major parts of the machine include blast wheel for giving high production output, roller conveyor for job conveying and the media recovery, consist of bucket elevator, screw conveyor, rotary screen seperator etc. and pulse rate type dust collector.
Essential Element :
1. Construction of Working Chamber : The heavy duty all welded cavinet is manufactured out of prime quality heavy duty steel plate and mounted on sturdy and rigid structural steel framework.Manganese steel liners are fitted in direct and indirect blast zone of the cabinet (complete lining).
2. Blast Wheel Assembly : The rotor is made out of EN grade material duly hardened. The drive system of blast wheel (rotor) entails a set of self-lubricated and self-aligning pedestal bearings. The rotor is dynamically balanced.
3. Abrasive Circulaion System : for continious and trouble free operation.
4. Pulse Jet type Dust Collection System : Dust Collector is provided to suck the dust from blasting cabinet.The filter bags of dust collector are made out of a non-woven PTEE pleated bags for low dust emission level.
5. Roller Conveyor : is provided at inlet and outlet of blasting cabinet driven by suitable variable AC drive.
