Excessive moisture will trigger furnace temperature fluctuation, poor activation performance and higher steam consumption.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Working principle of the industrial rotary activation furnace<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In physical\u2011method activated carbon production, carbonized feedstock is fed into the activation furnace. Saturated steam is injected as the activating agent. Under furnace temperatures of <strong>880\u20111050\u2103<\/strong>, gas\u2011solid activation reactions take place to open and expand internal pores within carbon particles, yielding porous activated carbon with a specific surface area ranging from 700\u20112000\u202fm\u00b2\/g.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The activation process proceeds in three sequential phases:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Pore\u2011opening Phase<\/strong>: Tar and amorphous carbon inside carbon particles are burnt away to unblock closed pores, with carbon burn\u2011off rate below 10%.<\/li>\n\n\n\n<li><strong>Micropore\u2011forming Phase<\/strong>: Selective oxidation acts on carbon matrices to generate abundant micropores, ideal for manufacturing high\u2011iodine\u2011value activated carbon.<\/li>\n\n\n\n<li><strong>Pore\u2011widening Phase<\/strong>: Continuous gasification\u2011burning of pore walls enlarges apertures and produces mesopores, suitable for activated carbon requiring high methylene\u2011blue value. The material burn\u2011off rate exceeds 50% in this phase.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Production Tip<\/strong>: To achieve a high iodine value (1400\u20111500\u202fmg\/g), raise the activation temperature to 1050\u2103, reduce rotary speed, and extend material residence time, which will significantly lower product yield. For maximum yield, keep the temperature below 950\u2103 to produce activated carbon with iodine value &lt;1100\u202fmg\/g.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"540\" data-id=\"13502\" src=\"https:\/\/www.charcoal-machines.com\/wp-content\/uploads\/2026\/09\/activated-carbon-rotary-regeneration-furnace.webp\" alt=\"activated carbon rotary regeneration furnace\" class=\"wp-image-13502\" srcset=\"https:\/\/www.charcoal-machines.com\/wp-content\/uploads\/2026\/09\/activated-carbon-rotary-regeneration-furnace.webp 720w, https:\/\/www.charcoal-machines.com\/wp-content\/uploads\/2026\/09\/activated-carbon-rotary-regeneration-furnace-300x225.webp 300w, https:\/\/www.charcoal-machines.com\/wp-content\/uploads\/2026\/09\/activated-carbon-rotary-regeneration-furnace-16x12.webp 16w\" sizes=\"auto, (max-width: 720px) 100vw, 720px\" \/><figcaption class=\"wp-element-caption\">Activated Carbon Rotary Regeneration Furnace<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"540\" data-id=\"13503\" src=\"https:\/\/www.charcoal-machines.com\/wp-content\/uploads\/2026\/09\/rotary-activation-furnace.webp\" alt=\"rotary activation furnace\" class=\"wp-image-13503\" srcset=\"https:\/\/www.charcoal-machines.com\/wp-content\/uploads\/2026\/09\/rotary-activation-furnace.webp 720w, https:\/\/www.charcoal-machines.com\/wp-content\/uploads\/2026\/09\/rotary-activation-furnace-300x225.webp 300w, https:\/\/www.charcoal-machines.com\/wp-content\/uploads\/2026\/09\/rotary-activation-furnace-16x12.webp 16w\" sizes=\"auto, (max-width: 720px) 100vw, 720px\" \/><figcaption class=\"wp-element-caption\">Rotary Activation Furnace<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Activated carbon rotary kiln main technical parameters<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Note: Parameters for furnace host only, excluding feeding, cooling, dedusting, and other auxiliary systems.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><thead><tr><th>Parameter Item<\/th><th>External\u2011Heated Rotary Activation Furnace<\/th><th>Traditional Internal\u2011Heated Rotary Activation Furnace<\/th><\/tr><\/thead><tbody><tr><td>Modell<\/td><td>JY\u20111600<\/td><td>Custom\u2011built rotary type<\/td><\/tr><tr><td>Cylinder Size<\/td><td>\u03a61.6\u202fm \u00d7 L12\u202fm<\/td><td>Custom dimension for different capacities<\/td><\/tr><tr><td>Cylinder Material<\/td><td>310S high\u2011temperature resistant stainless steel;baffle plate: 8\u202fmm 310S SS<\/td><td>Q235 carbon steel lined with refractory bricks<\/td><\/tr><tr><td>Activation Temperature Range<\/td><td>800\u20111050\u202f\u2103<\/td><td>880\u20111050\u202f\u2103<\/td><\/tr><tr><td>Material Residence Time<\/td><td>60\u2011120\u202fmin, variable\u2011frequency adjustable<\/td><td>60\u2011120\u202fmin, adjusted by rotary speed<\/td><\/tr><tr><td>Processing Capacity<\/td><td>1\u20112\u202ft\/d<\/td><td>0.15\u20110.25\u202ft\/h<\/td><\/tr><tr><td>Sealing Structure<\/td><td>Multi\u2011layer stainless steel fish\u2011scale seal<\/td><td>Ductile\u2011iron &amp;
