Different Types of Sandblaster According to Needs

Sandblasting is a technique in which extremely small pieces of material are shot with great pressure in order to clean the surface of an object. The surfaces on which a sandblaster is used are generally metal, glass, brick and sometimes wood too. When sandblaster is used, the obvious choice of material, at times some other abrasives are also used, such as steel grit, copper slag or walnut shells etc.

Uses of Sandblaster

Dust and Paint Removal: It manually a very difficult task to remove dust and paint from the surface of various objects and especially of the area is large, therefore sandblasters are used.

Concrete Cleaning: Sandblasters are used to clean concrete as they have a large area and with time get covered with various foreign materials.

Rust Removal: Before repairing the metal parts or welding them it is necessary to clean them of any rust and what better than using a sandblaster?

Small Part Shaping: When create small parts of an object with intricate patterns and equipment a level of precision is required and sandblasters provide with exactly that.

Gravity Fed Sandblaster

Types of Sandblaster

Sanblasting is a versatile technique that is used for many purposes across the globe but has three types of sandblaster which can be selected depending on your need or desired work:

Pressure Sandblaster: In this type of sandblaster, there is a canister containing sand which is already under a pressure. When this canister is connected to a gun through a special hose and when the trigger of the gun is pulled the sand blasts out with air and high pressure. This sand blaster is low maintenance but the cost may be slightly higher.

Gravity-Fed Sandblaster: As the name suggests in this sandblaster the sand is forced down from the top (due to gravity) into the barrel of the gun. There is hopper at the top of the gun that holds the sand supply, when the trigger is pulled the sand is forced to come out of the barrel. The more sand will fall from the hopper, the more the pressure and this helps to continue the flow. When the trigger of the gun is released, the opening between the barrel and the hopper closes, thereby keeping the remaining sand for future use.

Siphon Sandblaster: Another type is the Siphon Sandblaster in which suction is the main action source. In this type of sandblaster the gun is connected through two hoses (one is an air compressor and the other is a sand reservoir). When the air is turned on, it creates a suction through which the sand gets pulled out of the barrel. This type of sandblaster is relatively affordable and can be used continuously as the sand can be shifted back to the reservoir. When a large surface needs to be cleaned, siphon sandblaster is the best choice.
