Gyratory Screening Machines


Allgaier gyratory screening machines are used primarily in the particle board industry in order to effectively separate furnish into various groups. Within this context, chipped wood material is used in order to obtain the material for the core and outer layers in particle board.

Gyratory screening machines ARSM are an absolute classic when it comes to the screening machines used by the lumber industry, and the Jumbo model in particular is known for its outstanding furnish grading accuracy.
