What is the difference between water blasting machine and dry blasting machine?

 Sandblasting machine is divided into the dry sandblasting machine and wet sandblasting machine, each of which has advantages. Many people will ask if dry sandblasting is better for rust removal or wet sandblasting machine is better for rust removal? The dry sand blaster machine is powered by mechanical centrifugal force or compressed air. The abrasive (iron shot or sand) is sprayed onto the surface of the workpiece at a high speed through a special nozzle, and dirt and rust are removed by impact and friction. The processing quality is still relatively good.

The wet sandblasting machine is a combination of water jet and sand blasting technologies. It has the environmental protection and explosion-proof characteristics of water jet and the superior rust removal and paints removal effects of sand blasting. It is very suitable for flammable and explosive places, especially in storage. Anti-corrosion operations are carried out under normal operating conditions of oil tanks.

1. Efficiency: water sand blasting machine is not as efficient as dry sand blasting machine, the difference is obvious. The reason is simple, the liquid wet sandblasting machine mixes water into the abrasive, reducing the impact force. The dry sandblasting equipment sprayed out by others is full of sand, which is all effectively hit on the product. If your water sandblasting machine mixes a lot of water into it, the efficiency is inevitable.

2. Environmental pollution: water sand blasting machine can be said to prevent the generation of dust, which is one of the reasons why many manufacturers choose. Our company produces both portable sand blasting machines. I went to a dry sandblasting customer’s blasting room. Simply put, the dust generated by the blasting can't be tolerated without wearing protective clothing.

3. Cost, price: the price of water sand blasting machine and dry sand blasting machine can be said to be the same, both of which need to be driven by an air compressor. When calculating the cost of the wet sandblasting machine, it is also necessary to consider the consumption of water and the cost of adding rust inhibitors in the water.

4. Treatment effect: If it is only for removing rust, removing paint and other simple purposes, both can be achieved. If you don't do other treatments after sandblasting (such as stainless steel tanks), then you have to consider the color of the sandblasting. The matte effect of the sandblaster is more obvious. It is better to realize the difference of sandblasting color by adjusting the proportion of the mixed abrasive.
