Detailed Description

air pick brazing Scope of application：air pick borehole diameter： 34-42（mm） Perforating depth： 5（m） Impact energy： 75（J） impact frequency： 36（Hz） Pick brazing is a direct contact and work tools, pick brazing material, size and shape on the gas picks has remarkable effect on the productivity of pick brazing shape and length depending on the breakdown of the seam hardness, such as seam the harder the more short picks brazing, long conversely. Soft seam with crack or the mine is using length of 300-300 - mm, hard and toughening of the seam, use 150-300 mm. Pick brazing for the quality of different service life is an obvious difference, the reason lies in the quenching technology and material difference. product name Drill rod diameter Lengh Split the stone φ24（tail）φ30、φ40（head） 300-600 G10 Pick brazing φ24（tail）φ25、φ28（body） 300-3000 G10 Special steel pick brazing (hex) φ24（tail）φ25（body 300-3000 G20 Pick brazing φ30 450-3000 B87 Pick brazing φ28 φ32（On the margin） 500-1000 Pneumatic shovel bit φ17.5（tail）、φ20（body） 300-3000（Wide and narrow head） Hammer drill rod φ45-φ210 1000-2000
