The sand blast room is consist of  by shot peening Chambers, full curtain classifier, dust collector, pipe, blower, dust collecting device, sandblasting host, grid floor, transverse and vertical screw conveyor belt machine (horizontal screw conveyor, bucket elevator, electric control system, lighting system, air conditioning type sand blasting, fixed working platform, etc

QINGGONG has rich experience in designing and producing all kinds of air blast and wheel blast machines. Let us introduce sand blast rooms in laboratory for welding steel structure to you:


Sand is stored in the sandblasting tank. When sandblasting is carried out, the combination valve on the sandblasting tank ACTS to lift the sand sealing bracket on the sandblasting tank and charge the sandblasting tank. At the same time, the sand valve of the shot blasting equipment under the sandblast tank opens, the booster valve opens. Due to the charging of the sandblasting tank, the sand material is forced to be pressed out from the inlet of the sand valve to the outlet. The sand material in the outlet of the sand valve is accelerated through the boosting airflow. The mixed flow of the accelerated sand flow flows through the sandblasting pipe to the high-speed sandblasting gun and in the high-speed sandblasting gun to further accelerate the sand (the boosted airflow accelerates to supersonic speed); The accelerated sand is sprayed to the surface of the workpiece at a high speed to achieve the purpose of surface cleaning and strengthening.
