Origin of the blasting process

QINGDAO KNNJOO MACHINE INC. | Updated: Nov 27, 2015

World's first shot-blasting equipment was born 100 years ago, the United States. Began its main application on the surface of metal oxide skin removing impurities, and increase surface roughness, as well as aspects of the metal surface, and because of its high efficiency, environmental protection, and the advantages of recycling, on many occasions, and production is gradually replacing the traditional blasting methods. 

After a century of development, shot blasting equipment and technology is very sophisticated, its application is not in the field of heavy industry. In the 1970 of the 20th century, the world's first mobile blasting equipment in Bai Rui Teck (BLASTRAC) was born, its applications and spread quickly to the concrete surface coating process and ship deck on the surface treatment of metal surface coating, and direct the industry standard specifying construction methods and industry norms. 

With Bai sharp Thai grams (BLASTRAC) throwing pills equipment of constantly improved and technology of mature, its equipment form also by first of hand-held traction of form development expanded to itself, and car, variety form; throwing pills of range also by first of 25 cm evolution to applies different efficiency and uses of different width of products; drive form including has motor, and hydraulic, and gasoline machine, and diesel engine,. 

Accompanied by the blasting process matures, diversification of forms of technical innovation, equipment, shot blasting process and equipment relying on its proprietary technology and application, applications have expanded from the original industrial floor coating to the airport, highway and bridge maintenance and construction areas, and has been widely used in Europe and the United States. 

Shot blasting, by means of metal-mechanical material at very high speeds (around 70 m/s) and perspective projection on to a work surface, steel shot speed work surface, dealing with work surface impurities, attachments and other need to clean up the material of a surface treatment method. 

Against the surface of steel shot in support of cleaning equipment and under the impact of a rebound effect in itself, steel shot back to the separation system of the machine itself and impurities and impurities and can be recovered using steel shot automatic separation and recovery. Good steel shot inside the machine continues to recycle.
