Receiving a continuous high-volume mixture of circulating process water and freshly cut polymer pellets, the dehydrator rapidly strips away water and discharges dry, ready-to-pack plastic pellets with surface moisture as low as &lt; 0.05%.<\/p>\n<p>Featuring a multi-stage separation architecture, incoming slurry first passes through an inclined gravity pre-drainage chute that sheds over 90% of the transport water back to the tempered water reservoir. The pre-drained pellets then enter the vertical centrifugal drying chamber, where high-speed rotating rotor paddles propel the pellets upward in a spiral path against a precision non-clogging wedge wire screen basket. Strong centrifugal force expels residual water droplets outward through the screen slots while dried pellets exit tangentially from the top outlet.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>High-speed vertical centrifugal dewatering machine for continuous, high-efficiency solid-liquid separation of underwater and water-ring pellet slurry.<\/p>\n","protected":false},"featured_media":473,"template":"","equipment_category":[34,36],"process_stage":[69,78,44],"material_family":[93,131,133,129,95,132,92,91,89,90],"material_form":[75],"production_problem":[109,114],"class_list":["post-188","equipment","type-equipment","status-publish","has-post-thumbnail","hentry","equipment_category-drying-cooling-dewatering","equipment_category-pelletizing-auxiliaries","process_stage-compounding","process_stage-dewatering-and-drying","process_stage-post-pellet-treatment","material_family-eva","material_family-modified-plastics","material_family-multifunctional-masterbatch","material_family-resin","material_family-rubber","material_family-thermoplastic-elastomer","material_family-tpe","material_family-tpo","material_family-tpu","material_family-tpv","material_form-pellets","production_problem-high-surface-moisture","production_problem-insufficient-cooling"],"_links":{"self":[{"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/equipment\/188","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/equipment"}],"about":[{"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/types\/equipment"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/media\/473"}],"wp:attachment":[{"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/media?parent=188"}],"wp:term":[{"taxonomy":"equipment_category","embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/equipment_category?post=188"},{"taxonomy":"process_stage","embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/process_stage?post=188"},{"taxonomy":"material_family","embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/material_family?post=188"},{"taxonomy":"material_form","embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/material_form?post=188"},{"taxonomy":"production_problem","embeddable":true,"href":"https:\/\/polypelletizer.com\/wp-json\/wp\/v2\/production_problem?post=188"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
