Sand Blasting Equipment Working Principle

QINGDAO KNNJOO MACHINE INC. | Updated: Oct 09, 2017

Sandblasting machine is generally divided into two categories: dry sandblasting machine and liquid blasting machine. Dry sandblasting machine can be divided into two types of sandblasting machine, sandblasting machine, , Shot blasting machine dry sandblasting machine. The general composition of a complete suction dry blasting machine is generally composed of six systems, namely, structural systems, media power systems, piping systems, dust removal systems, control systems and auxiliary systems.

classification

Sandblasting machine is generally divided into two categories: dry sandblasting machine and liquid blasting machine. Dry sandblasting machine can be divided into two types of sandblasting machine, sandblasting machine, , Shot blasting machine dry sandblasting machine. General composition

A complete suction dry blasting machine is usually composed of six systems, namely, structural systems, media power systems, piping systems, dust removal systems, control systems and auxiliary systems.

working principle

Inhalation dry blasting machine is based on compressed air as the driving force, through the high-speed movement of air in the gun to form a negative pressure, the abrasive throughSand pipe. Inhalation spray gun and spray through the nozzle, sprayed to the surface to be processed to achieve the desired processing purposes. A complete press-in dry blast blasting unit is usually composed of four systems, namely pressure tank, medium power system, piping system, control system. Pressure dry sandblasting machine working principle: pressure into the dry sandblasting machine is compressed air as the driving force, through the compressed air in the pressure tank to establish the working pressure, the abrasive through the sand valve, into the sand pipe and by The nozzle is ejected and sprayed onto the machined surface to achieve the desired machining head.

How to filter sandblasting machine

1. To see the size of the workpiece, choose box-type sandblasting machine, mobile sandblasting machine, and automatic sandblasting machine;

2. To see the shape of the product, choose the specifications of the blasting machine, generally one meter below the fixed specifications, especially large to build or choose open.

3. The degree of surface requirements of the product, this depends on the specific use of dry or wet spray, if it is dry spray, then the choice of a lot of abrasive, wet spray is generally glass sand and so on.

4. Blasting machine some of the accessories to be familiar with sandblasting guns and sandblasting gloves are often changing things, because the sandblasting is actually very bad wear. 1, surface cleaning processing: metal oxide, carbide black, metal or non-metallic surface rust removal, such as gravity die-casting mold, rubber mold oxide or removal of the removal of the ceramic surface black spots, uranium color removal, Painted rebirth. 2, landscaping processing: all kinds of gold, K gold jewelry, precious metal products, extinction or surface treatment, crystal, glass, ripples, acrylic and other non-metallic surface processing and can make the surface of the product into a metallic luster. 3, etching processing: jade, crystal, agate, semi-precious stones, seal, elegant stone, antique, marble tombstones, ceramics, wood, bamboo and other etching art. 4, pre-processing processing: Teflon (TEFLON), PU, rubber, plastic coating, rubber drum (ROLLER), electroplating, metal spray welding, titanium and other treatment before the surface adhesion increased. 5, burr processing: bakelite, plastic, zinc, aluminum die-casting products, electronic parts, magnetic core, such as the removal of the burr. 6, stress relief processing: aerospace, defense, precision industrial parts, rust, in addition to paint extinction, renovation and other stress relief processing. 7, electronic parts processing: silicon chip surface and etching, wafer back impurity removal, electronic parts packaging overflow rubber, finished product printing to remove the clean, ceramic electric cleaning 8, the mold of the processing: the general mold surface of the sandblasting, mold Bite after the surface treatment, line cutting die, glass mold, tire mold, conductive rubber mold, shoe mold, bakelite mold, electroplating mold, key mode, plastic mold. 9, the processing of large work: large parts such as oil tank, chemical tank, hull, copper, metal huts, containers, the automotive industry, such as rust, paint, maintenance and large flat glass automatic surface treatment.
