What is the difference between a wet sandblasting machine and a dry sandblasting machine?

The main differences are different systems, different working principles, and different main features.

1. The system is different.

Liquid sandblasting machine.

Generally, a complete liquid sandblasting machine is generally composed of five systems, namely structural system, medium power system, pipeline system, control system and auxiliary system.

Suction type dry sandblasting machine.

Generally, a complete suction dry sandblasting machine is generally composed of six systems, namely structural system, medium power system, pipeline system, dust removal system, control system and auxiliary system.

Press-in dry sandblasting machine.

Generally, a complete press-in dry sandblasting machine working unit is generally composed of four systems, namely pressure tank, medium power system, pipeline system, and control system.

2. The working principle is different.

Suction type dry sandblasting machine.

The suction dry sandblasting machine is powered by compressed air, and the negative pressure formed in the spray gun through the high-speed movement of the air flow sucks the abrasive into the spray gun through the sand pipe and shoots out through the nozzle, and sprays it to the processed surface to achieve the expected processing purpose. In a suction dry blaster, compressed air is both the supply and acceleration power.

In a suction dry blaster, compressed air is both the supply and acceleration power.

Press-in dry sandblasting machine.

How press-in dry sandblasting machines work. Press-in dry sandblasting machine is powered by compressed air, through the working pressure established by compressed air in the pressure tank, the abrasive is pressed into the sand pipe through the sand outlet valve and injected through the nozzle, and sprayed to the processed surface to achieve the expected processing purpose. In press-in dry blasting machines, compressed air is both the supply and acceleration power.

Liquid sandblasting machine.

Compared with the dry sandblasting machine, the biggest feature of the liquid sandblasting machine is that it well controls the dust pollution during the sandblasting process and improves the working environment of the sandblasting operation.

Working principleThe liquid sandblasting machine uses the abrasive pump as the feeding power of the abrasive liquid, and transports the evenly stirred abrasive (a mixture of abrasive and water) into the spray gun through the abrasive pump. Compressed air is used as the acceleration power of the grinding liquid, through the air pipe, into the spray gun, in the spray gun, the compressed air accelerates the grinding liquid entering the spray gun, and is shot out through the nozzle, sprayed to the processed surface to achieve the expected processing purpose.

3. The main features are different.

Compared with the dry sandblasting machine, the biggest feature of the liquid sandblasting machine is that it well controls the dust pollution during the sandblasting process and improves the working environment of the sandblasting operation.

Dry sandblasting machines are pure abrasive blasting. In fact, there are dust-free sandblasting abrasives, such as RZG garnet sand, which has very little dust and is basically dust-free.

Outdated products, the derusting efficiency of the steel bar derusting machine is too low, hundreds of tons of steel bars, if you want to use the derusting machine one by one, the efficiency can be imagined, time-consuming, labor-intensive and labor-intensive. At present, the easiest way to remove rust is to spray steel bar rust remover.

Wet sandblasting machine and dry sandblasting machine are two common types of sandblasting equipment that have different applications and characteristics in the field of sandblasting processing.

1.The principle of operation is different: the wet sandblaster uses water and sand to mix to form a jet stream that sprays the sand onto the object to be processed at high speed. On the other hand, the dry sandblasting machine sprays the dry sand on the object to be processed without the participation of water.

2.Different ways of sand treatment: The wet sandblasting machine can clean the impurities and dust on the surface of the sand through the impact and flushing action of water, so as to obtain a better sandblasting effect.

Dry sandblasting machines, on the other hand, need to filter and clean the sand before blasting to ensure that the blasted sand is clean and free of impurities.

3.Different range of applications: Due to the involvement of water, wet sandblasting machines are suitable for treatment with high requirements on the surface of the object to be processed, such as sandblasting of fragile materials such as glass and ceramics.

Dry sandblasting machines, on the other hand, are suitable for materials that do not have strict surface requirements, such as steel, aluminum alloys, etc.

4.The environmental pollution situation is different: due to the participation of water in the wet sandblasting machine, a large amount of water mist and impurities will be generated during the spraying process, which is easy to cause environmental pollution.

The dry sandblasting machine does not have the participation of water, and the dust generated during the spraying process is far less than that of the wet sandblasting machine, and the environmental pollution is much smaller.

To sum up, there are differences between wet sandblasting machine and dry sandblasting machine in terms of working principle, sand handling method, application range and environmental pollution. When choosing to use, it is necessary to consider comprehensively according to the requirements of the specific processing material and environmental conditions.

The differences between wet and dry blasting are as follows:

First, the difference in the premise of work:

1. Dry sandblasting can be carried out without mixing sand and water when sandblasting.

2. Wet sandblasting must mix sand and water to carry out sandblasting operation when sandblasting.

Second, the difference in working principle:

1. Dry sandblasting is to pass the abrasive out of the sand valve by using compressed air as the power and the working pressure established by compressed air in the pressure tank.

2. Wet sandblasting is to spray the abrasive liquid to the surface of the workpiece to be processed at high speed through the spray gun by the abrasive pump and compressed air, and the sand is sprayed out of the sand valve.

3. Cause differences in working environments:

1. Dry sandblasting will cause a large amount of dust to pollute the environment when used, which seriously endangers the health of operators.

2. Wet sandblasting does not produce dust, does not discharge toxic wastewater, does not produce pollution to the environment, and the installation of the equipment is simple and convenient, and there is no need for a separate workshop.

In general, wet blasting is preferred over dry blasting for the health of workers.

Straight ** wet sandblasting is as follows:

Wet sandblasting is as follows:

Wet sandblasting is mainly aimed at sandblasting stainless steel parts, such as vacuum equipment, sewage treatment equipment, kitchen equipment and titanium alloy and aluminum alloy parts.

The liquid sandblasting machine places the abrasive in water, and uses the abrasive pump and compressed air to spray the abrasive liquid to the surface of the workpiece to be processed at high speed through the spray gun, so as to achieve the effect of surface cleaning and polishing of the part. The liquid sandblasting machine has high sandblasting efficiency and low abrasive consumption, which can achieve the purpose of improving the surface finish and strong bottom of the workpiece. Due to the wet sealing operation of the liquid sandblasting machine, the use of tap water and natural sand (pill) for the grinding liquid abrasive, and the circulating work, it does not produce dust, does not discharge toxic wastewater, and does not produce pollution to the environment, and the installation of the equipment is simple and convenient, and there is no need for a separate workshop.

The dry sandblasting machine is powered by compressed air, and the working pressure established by the compressed air in the pressure tank passes the abrasive out of the sand valve.

Sandblasting rust removal technology has a good rust removal effect, through quartz sand, river sand, iron sand and other abrasives, under a certain air pressure, sprayed onto the steel surface, using the hardness, impact toughness and edges and corners of the abrasive itself, the rust on the steel surface is removed from a corrosion protection construction method. Although this method is easy to use, it will cause a large amount of dust to pollute the environment, seriously endanger the health of the operator, and long-term use of this method for cleaning will damage the surface of the tank.

The water sandblasting machine is an upgraded version of the dry sandblasting machine, which has higher efficiency through the original sandblasting technology combined with hydraulic removal, does not damage the surface, can clean various shapes, various large-area cleaning, and can be configured with sandblasting accessories for surface polishing treatment.

Summary. It is better to be both wet and dryThe difference between a wet sandblaster and a dry sandblaster is that dry sandblasting is not suitable for cleaning grease and dirt, while wet sandblasting machines do not have this problem.

For golf workpieces that need to avoid the color difference of the material surface caused by the temperature rise of sandblasting, wet sandblasting is more suitable. The most important feature is the use of fine sand, wet blasting has a unique effect, while dry has its limitations. Generally, when the grit size of sand is more than 400, it is necessary to consider using a wet sandblasting machine.

Wet sandblasting machines are widely used in the cleaning of precision molds, electronic parts, piston rings, aviation parts, surface pretreatment of titanium-plated workpieces, circular saw blades and oil-stained workpieces. However, it is relatively higher than the dry sandblasting machine, and the work efficiency is not as good as the dry sandblasting machine.

Sandblasting machine wet and dry and dry sandblasting are good.

1. The water consumption is different

Dry sand method: no water is required.

Wet sand method: The production process requires the consumption of a large amount of valuable water resources.

2. Different environmental impacts:

Dry sand making method: the process is recognized as a better process, and the impact on the environment is small.

Wet sand making method: has a greater impact on the environment.

3. The quality of finished sand.

Dry sand method: the cost is higher.

Wet sand making method: Although both water and separator can remove mud powder from the sand, the wet sand making method will be more effective. Such finished sand is used in the construction industry, which can greatly increase its resistance to pressure and workability.

The main equipment used in the two sand making processes is the same, both are crushers and sand making machines as the main body, and the purpose is to improve the quality of the machine-made sand and make the machine-made sand meet the standards of construction sand.

1. The subsequent configuration equipment is different

Wet sand making is the mode of the sand washing machine used, which can reduce the soil content of the machine-made sand, and the sand particles have a round appearance and beautiful quality. Dry sand making is a mode that uses a separator, which can achieve sand powder separation, select high-quality sand particles that meet the construction sand requirements, and also collect dust as a by-product.

2. The applicable areas are different

Wet sand making is suitable for areas with abundant water resources and close distance from water sources, and wet sand making can also establish sedimentation tanks to realize the recycling of water resources. Dry sand making is not limited by environmental areas, and sand production can also be achieved in areas where water resources are scarce.

3. The investment cost is different

The process of wet sand production requires the use of a large amount of water for cleaning, while the dry sand making is separated by a separator, which does not require the use of a large amount of water.

Advantages of wet sand making:

1.There is no dust pollution in the production process of wet sand making, reducing air pollution.

2.The sand made by wet sand making has a clean surface, a round appearance, and a good appearance.

Disadvantages of wet sandmaking:

1. A large amount of water resources are needed in the process of wet sand making, and the cost is high.

2. Due to the limitation of the environment and geographical area, it cannot be used if the water resources in the area are insufficient.

Advantages of dry sand making:

1. In the process of dry sand production, the cost of water resources is reduced, and it is not limited by the regional environment.

2. The dry sand production line has a compact layout and a small footprint.

Disadvantages of dry sand making:

1. The dust content in the dry production process is large, which is easy to cause air pollution.

2. The raw materials for dry sand making are high, and the content of impurities such as soil and organic matter in the sand and gravel needs to be strictly controlled.

Look at the sand making process, have you chosen the right one?

In the current ban on natural sand and gravel mining, machine-made sand will replace natural sand and gravel aggregates on a large scale in the construction industry, the sand making process is particularly important. So how to choose the right sand making process according to your own situation?

1.Dry sand making.

From the name, we can clearly see that this sand making process does not use much water, and is suitable for areas with relatively drought and little rainfall. The specific processing process of dry sand making is as follows: raw material - > vibrating feeder (removal of soil waste) - > coarse crushing - > medium fine crushing - > screening (screening large aggregates) - > sand making - > screening (screening small aggregates) - > dust removal - > powder separation - > finished sand.

When discharging, the stone powder content in the machine-made sand can be adjusted by the separator to meet the standards of urban construction and hydropower engineering, and is used in construction projects, railways and other departments. The resulting fine powder can be used by dust removal and separators** for road bedding or slag brick raw materials. It can be seen that dry sand making can make full use of the discharged product.

2.Wet sand making.

The process of wet sand making and dry sand making is basically the same, but a large amount of water resources are required in the sand making process, so wet sand making is more suitable for rainy and abundant water resources. The specific processing process of wet sand making is as follows: raw material - > vibrating feeder (removal of soil waste) - > coarse crushing - > medium fine crushing - > screening (screening large aggregates) - > sand making - > screening (screening small aggregates) - > sand washing machine - > finished sand.

Compared with dry sand making, you will find that they only have a slight difference in the processing process, that is, the sand washing machine replaces the separator and dust collector, which requires a lot of water resources in the process, there is no dust pollution in the production environment, and the finished product is cleaner and better quality, but the output is lower.

After understanding the first two sand making processes, the dry and wet integrated sand making process is basically clear. That is, the dry sand making is combined with the wet sand making, and the aggregate is washed during the previous screening, and the finished sand part is no longer passed through the sand washing machine. This processing technology also requires a certain amount of water resources, and the cost of sand making is higher than that of dry sand making, and lower than that of wet sand making.

When choosing the sand making process, we should choose according to the requirements of the region, water resources, raw materials and discharge, but from the perspective of environment and cost, it is generally recommended to choose dry method, followed by dry and wet integration, and wet sand making. Water resources are the scarce resources in China, if the content of soil and organic matter can be controlled, the water content of the finished sand through dry sand production is low, the yield is high, and it is not affected by seasonal and other factors, it is a very popular sand making process when making sand.

If you have any other questions related to the configuration of the production line and the processing technology, you can consult it.
