Its mission is to purify the waste stream from pretreatment, eliminating heavy and highly dense elements (such as metals or stones) to obtain high-purity light material. By ensuring this cleaning, the Windsifter becomes an ally to protect, reduce wear, and extend the service life of secondary shredders in treatment lines.

The light material, having lower density, is propelled by the air and \"flies\" over the conveyor into the stabilization chamber. Inside this chamber, chain and plate screens prevent the light materials from continuing to float in the air flow, forcing them to fall by gravity toward the exit belt. On the other hand, heavy material that fails to overcome the curve of the banana conveyor or be pushed by the air falls directly by gravity toward its own reject chute or heavy material conveyor. Finally, the air laden with fine particles is aspirated, taken to the bag filter for cleaning, and returned clean to the impulsion fan to start the cycle again."}],"equipos_gallery":[{"equipos_gallery_photo":["2491"]},{"equipos_gallery_photo":["2490"]},{"equipos_gallery_photo":["2489"]}],"equipos_video":"https:\/\/bianna.com\/wp-content\/uploads\/MW_Bianna-360o-Web.mp4","equipos_video-explosionado":"https:\/\/www.youtube.com\/watch?v=DCC4Qyk5VKM&t=5s","equipos_diagram-image":[{"width":150,"height":84,"file":"MW_bianna_diagrama.jpg","filesize":193584,"sizes":{"image-480":{"file":"MW_bianna_diagrama-480x269.jpg","width":480,"height":269,"mime-type":"image\/jpeg","filesize":12550,"url":"https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama-480x269.jpg"},"image-720":{"file":"MW_bianna_diagrama-720x403.jpg","width":720,"height":403,"mime-type":"image\/jpeg","filesize":24128,"url":"https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama-720x403.jpg"},"image-960":{"file":"MW_bianna_diagrama-960x538.jpg","width":960,"height":538,"mime-type":"image\/jpeg","filesize":38423,"url":"https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama-960x538.jpg"},"image-1250":{"file":"MW_bianna_diagrama-1250x700.jpg","width":1250,"height":700,"mime-type":"image\/jpeg","filesize":58359,"url":"https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama-1250x700.jpg"},"image-1920":{"file":"MW_bianna_diagrama-1920x1075.jpg","width":1920,"height":1075,"mime-type":"image\/jpeg","filesize":117035,"url":"https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama-1920x1075.jpg"}},"image_meta":{"aperture":"0","credit":"","camera":"","caption":"","created_timestamp":"0","copyright":"","focal_length":"0","iso":"0","shutter_speed":"0","title":"","orientation":"0","keywords":[]},"ID":"2496","name":"MW_bianna_diagrama.jpg","path":"\/var\/www\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama.jpg","url":"https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama.jpg","full_url":"https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama.jpg","title":"MW_bianna_diagrama","caption":"","description":"","alt":"Diagrama Windsifter","srcset":"https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama.jpg 2500w, https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama-480x269.jpg 480w, https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama-720x403.jpg 720w, https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama-960x538.jpg 960w, https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama-1250x700.jpg 1250w, https:\/\/bianna.com\/wp-content\/uploads\/MW_bianna_diagrama-1920x1075.jpg 1920w"}],"equipos_diagram-legend":[{"equipos_leyenda_color":"#e0241a","equipos_leyenda_text":"Material"},{"equipos_leyenda_color":"#25cee8","equipos_leyenda_text":"Air"}],"equipos_diagram-points":[{"equipos_diagram-points_coordinate-x":"19","equipos_diagram-points_coordinate-y":"48","equipos_diagram-points_title":"Tolva de alimentaci\u00f3n","equipos_diagram-points_description":"Inlet point where mixed material is fed into the equipment to initiate density separation."},{"equipos_diagram-points_coordinate-x":"33","equipos_diagram-points_coordinate-y":"78","equipos_diagram-points_title":"Heavy fraction","equipos_diagram-points_description":"Dense material (stones, metals) that falls by gravity as it is not carried by the airflow.
