Hook strip screen installation on Hunter-D shale shaker

Hook strip screen installation

Aipu Hunter-D series shaker will be configured with hook strip screen. Usually, we suggest ship shaker without screen panels installed. This will prevent any possible damage on the screen panel. So installation of screen panels for the first time will be important for users.

Prior to shaker screen installation, remove all package and shipping materials from the shaker bed. The tensioning bolts and lock system are fastened well. Locating bars provided along the interior well ensure screen panels are centered left to right on screen bed. Draw bolts are then engaged and tightened in stages, going from left to right side and finishing with final tensioning on the right side. The right and left sides of the equipment are determined by standing at the feed end and looking forward to discharge end.
