Airless tunnel type

Overview

An airless tunnel type machine is a shot blasting equipment that utilizes high-speed turbines to propel abrasive media at the workpieces. The workpieces are conveyed through a tunnel-like chamber for effective cleaning and surface preparation. As the leading shot blasting machine supplier in India, we are committed to delivering the finest machines and exceptional customer support.

Airless Tunnel Type Shot Blasting Machine Manufacturer And Supplier

"PCS" has a range of Airless Shot Blasting Machine Tunnel Types with a number of Blast Wheels varying according 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 the numbers of blast wheels depend upon the structure of the job for attaining a homogeneous finish.

Major parts of the machine include a blast wheel for giving high production output, a roller conveyor for job conveying and media recovery, consisting of a bucket elevator, screw conveyor, rotary screen separator etc. and pulse rate type dust collector.

Essential Element :

  • 1. Construction of Working Chamber: The heavy-duty all-welded cabinet is manufactured out of prime quality heavy-duty steel plate and mounted on a sturdy and rigid structural steel framework. Manganese steel liners are fitted in the 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 the blast wheel (rotor) entails a set of self-lubricated and self-aligning pedestal bearings. The rotor is dynamically balanced.
  • 3. Abrasive Circulation System: For continuous and trouble-free operation.
  • 4. Pulse Jet type Dust Collection System: Dust Collector is provided to suck the dust from the blasting cabinet. The filter bags of the dust collector are made out of non-woven PTEE pleated bags for low dust emission levels.
  • 5. Roller Conveyor: It is provided at the inlet and outlet of the blasting cabinet and driven by a suitable variable AC drive.
