This can occur during pressing or when removing them. It can leave residues or block parts of the mold cavities..<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Poor briquette discharge <\/strong>means problems when taking briquettes out of the mold. This can include dragging, breakage, unstable release, or not fully removing the briquette.<\/p>\n\n\n\n<p data-block-type=\"core\">In practice, we closely relate these two issues. Mold sticking&nbsp;often leads to poor discharge, while discharge problems usually indicate unstable structure formation or unfavorable mold\u2013material interaction during briquetting.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"4-key-factors-behind-mold-sticking-and-poor-briquette-discharge\" data-block-type=\"core\"><strong>4 Key Factors Behind Mold Sticking and Poor Briquette Discharge<\/strong><strong><\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\">From a briquetting process&nbsp;perspective, mold sticking&nbsp;and poor discharge are rarely caused by a single factor. In practice, they result from multiple variables becoming unbalanced at the same time. Based on extensive on-site briquetting experience.<\/p>\n\n\n\n<p data-block-type=\"core\">The following four factors are the most common and most frequently overlooked.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" data-block-type=\"core\"><strong>1. Raw Material Moisture Imbalance<\/strong><strong><\/strong><\/h3>\n\n\n\n<p data-block-type=\"core\">Moisture-related sticking is mainly caused by improper moisture distribution rather than simply too much or too little water.<\/p>\n\n\n\n<ul class=\"wp-block-list\" data-block-type=\"core\">\n<li data-block-type=\"core\"><strong>Excess surface moisture<\/strong>&nbsp;makes materials soft and adhesive. During briquetting, water and fines are squeezed toward the mold, forming high-adhesion zones that increase friction during demolding.<\/li>\n\n\n\n<li data-block-type=\"core\"><strong>Insufficient moisture<\/strong>&nbsp;limits binder activation and particle compaction, resulting in loose briquettes with rough surfaces that are difficult to release.<\/li>\n\n\n\n<li data-block-type=\"core\"><strong>Uneven moisture distribution<\/strong>&nbsp;during mixing creates wet agglomerates that can trigger localized sticking, which may quickly spread across multiple mold cavities.<\/li>\n<\/ul>\n\n\n\n<p data-block-type=\"core\">Differences in particle size, surface area, and water absorption between raw materials further amplify these effects.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\" data-block-type=\"core\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-768x1024.jpg\" alt=\"Raw material wet test\" class=\"wp-image-18574\" style=\"width:500px\" srcset=\"https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-768x1024.jpg 768w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-225x300.jpg 225w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-1152x1536.jpg 1152w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-1536x2048.jpg 1536w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-9x12.jpg 9w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/Raw-material-wet-test-scaled.jpg 1920w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\" data-block-type=\"core\">Raw material wet test<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" data-block-type=\"core\"><strong>2.
