\n Mixing screws are required for mixing and shredding biomass; these must be able to withstand high mechanical stresses during continuous operation.\r\n\r\n <\/div>\n<\/div>\n

\n\n \n\n\n

During the process, the mixer screws are exposed to both severe wear caused by the material being cut and high levels of corrosion caused by the aggressive, moist medium.<\/p>\n

The challenge<\/strong><\/p>\n

The spiral must be bent at a uniform pitch and welded to the worm body or hub with minimal distortion.<\/p>\n

The requirements include precise geometry and concentricity, consistently clean weld seams, and a design capable of withstanding the combined effects of wear and corrosion over long service life\u2014all while accommodating the demanding handling of large, heavy components.<\/p>\n

The solution – unique and clever<\/strong><\/p>\n

L+M Industriestahlbau supplies <\/a>the mixer screws as complete units.
\nThanks to precise preparation, fabrication using jigs, and a carefully selected welding sequence, a custom-made, robust assembly was created that withstands the high stress and corrosion demands of the biomass process.<\/p>\n
