Q69 Roller conveyor shot blasting machine is a multi-functional shot blasting equipment for cleaning structural parts, H-beam, steel plate and other types of steel. It can make the work piece be subjected to strong and dense projectiles from different coordinate orientations , remove the rust spots and welding slag and oxide layer, and obtain a uniform and uniform metallic luster surface to remove stress and improve the quality of steel structure and steel surface finish. Corrosion resistance.

Feature of Q69 roller shot blasting pretreatment lines

Q69 shot blasting pretreatment lines for steel plates and profiles is mainly composed of four parts: preheating, shot blasting, painting and drying. According to the user’s production needs, it can be shot blasting with a single machine, or it can be connected to realize continuous operations of preheating, hot shot cleaning, painting and drying. It is suitable for rust removal and painting (ie pretreatment) on the surface of section steel. , and can carry out shot blasting and rust removal for long structural parts.

  1. The production line can be programmed and controlled across the board.
  2. The design mechanism is compact and occupies a small area.
  3. The computer-aided design (CAD) is used to draw the simulated projection diagram, and the overall arrangement is more reasonable.
  4. The cleaning room is protected by steel plates, the service life is greatly improved, and the appearance is beautiful and easy to replace.
  5. The fourth-generation cantilever centrifugal blast wheel is adopted, which significantly improves the cleaning efficiency and quality.
  6. Using shift memory and photoelectric detection, automatically measure the thickness and width of the steel plate, automatically adjust the width of the throwing belt and the lifting height of the cleaning device.
  7. The four-stage variable frequency speed regulation of the roller table on the whole line can be fine-tuned in sections or on the whole line, which realizes high-precision synchronous transportation under variable load conditions, and ensures the quality of shot blasting and painting and drying of pretreated steel.
