Dustless Concrete Bridge Waterproof Shot Blast Machine

        Portable shot blasting machine blasts the pills on the road surface at high speed and certain angle by the method of mechinery , make pills impect the surface of the road and make the road surface roughness, reach the effect of removing residuum,at the same time,dust collector will produce negative pressure to make pills and impurities and dust dust recovery after air cleaning, intact pills will automatically be recycled to used, and impurities and dust will drop into the dust collecting box. 

       Function of road surface blasting once will be enough clear away surface laitance of concrete and remove impurities, and can undertake  hair treatment on the surface of concrete, make its surface well-distributed roughness, greatly improving the adhesive strength of the waterproof layer and concrete base layer, so that the waterproof layer and bridge deck can better combination, and at the same time the crack of concrete can be fully exposed, have the effect of nip in the bud.







Working Principle;

Shot material in the lower part of separation box is from the feeding tube into the blasting  compo nents and driven by the motor. The high-speed rotating shot will be thrown and stroke against the surface of workpieces at the speed of 80m/s. And thus carry out clean-up operation. Under the effect of negative pressure, the shot abrasive and dust will be back into sand separation box where the shot, dust and impurities will be separated completely. Good shot materia into the blast is expected to continue to use.
