Environmental sand blasting machine is designed for cleaning large metal workpiece ,wipe off the paint and rust , oxide skin.
This machine is environmental, produce no dust . this machine adopt automatic recycle technology，so it can result in good cleaning quality,
you can also get the roughness you want on your workpiec surface.
Main technical parameter
Air pressure:0.5—0.65Mpa Air consumption: 3—8m3/min
Abrasive Media：mesh size 14—100,（1.6—0.06mm）.brown fused aluminum, copper grit, silica sand, steel grit, steel shot , glass bead.
According to different workpiece and different technological requirements , choose the right media .(for example, steel shot size should be less 1mm)
Power supply: 380V 50HZ Motor power: 4KW×2
Nozzle diameter: φ9 machine weight: 560kgs
cleaning surface capacity: Sa2.5-3 working efficiecy: 9-15m2/h
capacity: 450kgs abrasive media
boundary dimension: 1790×980×1810(mm)
air supply hose inner diameter: G1 1/4(φ32 mm)
sandpipe length: 5, 10, 15, 20(m)
recycling pipe length: 5, 10, 15, 20(m)
1.Check the machine to to assure the joints has no air leakage. Assure there is no breakage of the pipe.
2.To check the air pressure and air consumption,they should be the same as the technical parameter.
The compressed air should be dry, clean and no oil .
Notice: if it is just reach the parameter, there should be sand gas tank to put between compressor and sand blasting machine to assure the air supply is steady and continuous.
3.The abrasive sand put in the sand tank should be epigranular ,dry , inclusion-free, no dust,the mesh size should be according to the parameter.
Or the sand cannot be shaken out.
4.When adding sand , please open the three clamp on separator cartridge.take down the eparator cartridge.
Then add the sand .But the sand should be screened by the screen which meet the requirement of the parameter of the mesh size of the abrasive sand.
5.The filter element in the filter cartridge should be cleaned up at regular intervals
6.The vacuum pump motor should be covered in case of the sand fall into it.
7.Turn on the the vacuum pump before starting to operate this machine.
Then open the ball valve(15),check (13)pressure gage , then open stop valve(18).
8.Open the electric swich on the handel and open the sand valve (9) , tnen began to sand blasting.
9.Adjust sand valve(9) , stop valve(18),pressure regulating valve(13) to adjust sand flow rate
10.When sand blasting your workpiece, the hairbrush should be vertical and cannot leave from the workpiece.
11.When stop sand blasting or have a rest , the ball valve (15) Should be turn off .
12.Check and clean the screen on the separator tank (3), if it is broken ,you should change another one.
13.When add the sand , please turn off the switch and power supply on the c air supply ball valve(15) .
14.Please take off silencer and clean up its copper wire mesh in case of blocking .
15.Do not use machine out door on raining day; do not make the machine wet.
16.When the machine leave unused，please tie up the pipes, clean and wipe the machine.
17.The sand should be screened，it should be dry , no dust.,epigranular .
18.The compressed air should be clean ,dry, oil-free,pressure stability.
19.Clean machine every day after use.
