Steel structure treatment sandblasting machine parameters:

Sand tank diameter: 600MM   Sand tank height: 1300MM

Sand tank volume: 0.3 cubic meters 

Rust removal efficiency: 15-30 square meters / hour

Air consumption: 3 cubic meters / minute (single gun)

Air source pressure: 0.6-0.7MPA

By configuration:

1)Basic type: pure manual type, which is basically a pressure-retaining assembly.

Intake valve (ball valve control switch) + sand control valve (ball valve control switch). Electric control and pneumatic control system are not installed,

It requires 2 people to operate at the same time, one person takes a gun to blast the workpiece, and the other person controls the machine switch.

2)Pressure maintaining type: electric control type or pneumatic control type

Intake valve (aluminum alloy globe valve) + sand control valve (EMPAIR air-controlled sand valve or manual sand valve).

The sand tank is always under pressure and needs to be manually relieved.

The characteristics are: no matter any switch on the spray gun, as long as the exhaust ball valve on the top side of the sand tank is not opened, the pressure in the cylinder will not be released

(except manual sand valve self-discharge: it will cause serious sand accumulation in the sand pipe), suitable for short-term point sandblasting.

 3)Pressure relief type: electric control type or pneumatic control type

Intake valve (aluminum alloy globe valve) + sand control valve (EMPAIR air control sand valve or manual sand valve) + automatic air control exhaust valve.

When the sand tank is blasting, the pressure in the tank is the working pressure, and the tank is automatically exhausted when it stops, and the pressure in the tank is 0, which is suitable for long-term large-area blasting.

The pressure in the tank will never exceed the limit pressure, which plays the role of safety guarantee, and is also a necessary assembly method for automatic sand return.

 Pressure mobile sandblasting machine series products are widely used in sandblasting and three-dimensional engraving of glass, marble and other stone materials, shipbuilding sandblasting, bridges,

Surface treatment of steel structures such as railways, containers, and petrochemical facilities before painting, rust removal and anti-corrosion treatment, and fancy sandblasting for denim clothing.

1,Compact structure, superior performance, simple and convenient operation.

2,The design and production of the cylinder body conform to the pressure vessel standard, which is safe and reliable.

3,Standard common parts are used, easy to replace, and the cost is lower.

4,The instant control function is installed, and electric control or pneumatic control is adopted to meet the different needs of customers, and it can be operated by one person alone.

5,The shell is sandblasted and adopts advanced anti-rust paint to prevent rust.

6,Add wheels, easy to move.   

Abrasive control; sand for blasting and rust removal requires hard particles, angular, dry and free of mud and other impurities;

Quartz sand is better, coarse river sand is also acceptable; at the same time, sand transportation conditions, unit price, and recovery energy should be considered.

Force and other factors; the particle size of sand is preferably 0.5 to 1.5 mm, and it must be dried and stored before screening.

In the shed and indoors, the sieve size is: coarse sieve 40-48 holes (particle size 1.2mm), fine sieve 372-476孔

（particle size0.3mm)

During sandblasting operation, the air pressure of the air compressor is 6.0×105～6.5×105Pa, and the pressure amplitude is

0.5×105～1.0×105Pa。Generally, the air pressure of the sand bucket is 4.5×105～5.5×105Pa, not less than

4.0×105Pa。Before sandblasting, check whether the various pipes and control valves of the sandblasting machine are well connected, whether they are in the appropriate switch position,

Whether the protective tools, safety belts (ropes) and oxygen supply devices worn by sandblasters are safe and reliable, as well as the wear of the nozzles, when the orifice

The nozzle should be replaced when the diameter increases by 25%.

Compressed air must be processed by cooling device and oil-water separator to ensure dry and oil-free;

The oil-water separator must be cleaned regularly, and the distance from the nozzle to the surface of the base steel is preferably 100-300mm.

The non-sandblasted parts should be shielded and protected before sandblasting.

The angle between the spraying direction and the normal line of the surface of the base steel should be 15°~30°. After sandblasting and rust removal, and before the next process,

In case of rain or other conditions that cause the surface of the base steel to be wet, use a dry

Compressed air is used to dry the surface moisture before construction. If sandblasting is required again, the abrasive requirements cannot be reduced, so as not to reduce the roughness.
