developed. All refiners are equipped with variable-speed motors. The refiner loop is connected to several tanks for refining studies in recirculation or single-pass mode. The refiners allow for a range of refining prior to papermaking as well as for a comparison of the benefits provided by each type of machine. Our production scale refiners include:<\/p>\n\n\n<style>.kadence-column50_b6e79f-cc > .kt-inside-inner-col,.kadence-column50_b6e79f-cc >

pulp<\/strong>&nbsp;products. The PDC currently has three different plate types for this refiner, depending on the application.

paper industry and other related industries. It turns&nbsp;wood chips into pulp, conditions the pulp, and makes pulp of&nbsp;synthetic fibers, glass fibers and carbon fibers. With this machine, it is easy to perform processing into fiber and fibrillation of various polymers in diverse fields. Its shape is the same as the practical&nbsp;refiner used in the manufacturing plant, producing the same quality&nbsp;of the actual final product.<\/p>\n<\/div><\/div>\n\n<\/div><\/div>\n\n<style>.wp-block-kadence-spacer.kt-block-spacer-50_5216a8-d4 .kt-block-spacer{height:40px;}.wp-block-kadence-spacer.kt-block-spacer-50_5216a8-d4 .kt-divider{border-top-width:1px;height:1px;border-top-color:#eee;width:80%;border-top-style:solid;}<\/style>\n<div class=\"wp-block-kadence-spacer aligncenter kt-block-spacer-50_5216a8-d4\"><div class=\"kt-block-spacer kt-block-spacer-halign-center\"><hr class=\"kt-divider\" \/><\/div><\/div>\n\n\n<style>.wp-block-kadence-advancedheading.kt-adv-heading50_ede767-0e, .wp-block-kadence-advancedheading.kt-adv-heading50_ede767-0e[data-kb-block=\"kb-adv-heading50_ede767-0e\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading50_ede767-0e mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading50_ede767-0e[data-kb-block=\"kb-adv-heading50_ede767-0e\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading50_ede767-0e img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading50_ede767-0e[data-kb-block=\"kb-adv-heading50_ede767-0e\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h3 class=\"kt-adv-heading50_ede767-0e wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading50_ede767-0e\">PFI Mill<\/h3>\n\n\n\n<p>The PFI Mill is a high-precision laboratory refiner designed to evaluate the refining behavior of pulp under standardized conditions (ISO 5264-2, TAPPI T248). It processes 5\u201340\u202fg pulp samples at adjustable pressures (1.0\u20135.5\u202fN\/mm), simulating industrial refining to generate reproducible data on fiber development, freeness, and energy consumption. Ideal for R&amp;D environments, it features automated cylinder control, real-time monitoring of refining parameters, and robust construction for consistent, repeatable testing of fiber-based materials.<\/p>\n<\/div><\/div>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n<style>.kb-row-layout-id50_c70382-87 > .kt-row-column-wrap{align-content:start;}:where(.kb-row-layout-id50_c70382-87 > .kt-row-column-wrap) > .wp-block-kadence-column{justify-content:start;}.kb-row-layout-id50_c70382-87 > .kt-row-column-wrap{column-gap:var(--global-kb-gap-md, 2rem);row-gap:var(--global-kb-gap-md, 2rem);padding-top:var(--global-kb-spacing-sm, 1.5rem);padding-bottom:var(--global-kb-spacing-sm, 1.5rem);grid-template-columns:minmax(0, 1fr);}.kb-row-layout-id50_c70382-87 > .kt-row-layout-overlay{opacity:0.30;}@media all and (max-width: 1024px){.kb-row-layout-id50_c70382-87 > .kt-row-column-wrap{padding-top:0px;padding-right:50px;padding-bottom:0px;padding-left:50px;grid-template-columns:minmax(0, 1fr);}}@media all and (max-width: 767px){.kb-row-layout-id50_c70382-87 > .kt-row-column-wrap{padding-right:25px;padding-left:25px;grid-template-columns:minmax(0, 1fr);}}<\/style><div class=\"kb-row-layout-wrap kb-row-layout-id50_c70382-87 alignnone wp-block-kadence-rowlayout\"><div class=\"kt-row-column-wrap kt-has-1-columns kt-row-layout-equal kt-tab-layout-inherit kt-mobile-layout-row kt-row-valign-top\">\n<style>.kadence-column50_e9029b-cf > .kt-inside-inner-col,.kadence-column50_e9029b-cf > .kt-inside-inner-col:before{border-top-left-radius:0px;border-top-right-radius:0px;border-bottom-right-radius:0px;border-bottom-left-radius:0px;}.kadence-column50_e9029b-cf > .kt-inside-inner-col{column-gap:var(--global-kb-gap-sm, 1rem);}.kadence-column50_e9029b-cf > .kt-inside-inner-col{flex-direction:column;}.kadence-column50_e9029b-cf > .kt-inside-inner-col > .aligncenter{width:100%;}.kadence-column50_e9029b-cf > .kt-inside-inner-col:before{opacity:0.3;}.kadence-column50_e9029b-cf{position:relative;}@media all and (max-width: 1024px){.kadence-column50_e9029b-cf > .kt-inside-inner-col{flex-direction:column;justify-content:center;}}@media all and (max-width: 767px){.kadence-column50_e9029b-cf > .kt-inside-inner-col{flex-direction:column;justify-content:center;}}<\/style>\n<div class=\"wp-block-kadence-column kadence-column50_e9029b-cf\"><div class=\"kt-inside-inner-col\"><style>.wp-block-kadence-advancedheading.kt-adv-heading50_956081-42, .wp-block-kadence-advancedheading.kt-adv-heading50_956081-42[data-kb-block=\"kb-adv-heading50_956081-42\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading50_956081-42 mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading50_956081-42[data-kb-block=\"kb-adv-heading50_956081-42\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading50_956081-42 img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading50_956081-42[data-kb-block=\"kb-adv-heading50_956081-42\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<p class=\"kt-adv-heading50_956081-42 wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading50_956081-42\">To begin working with us, visit our <a href=\"https:\/\/umaine.edu\/pdc\/working-with-us\/\">Working with the PDC<\/a> page.<\/p>\n<\/div><\/div>\n\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Our pilot plant is fully equipped to perform all major areas of stock preparation, including size reduction, repulping, cleaning, screening, and refining.&nbsp;We can take virtually any raw material \u2013 from wood, agricultural residuals, plant, or synthetic source \u2013 and produce a wide range of products from laboratory to commercial scale.
