This not only disrupts production process but also increases recycling costs and material losses.<\/p>\n\n\n\n<p data-block-type=\"core\">Addressing these raw material challenges at the source ensures reliable briquette performance and more efficient recycling or smelting operations.<\/p>\n\n\n\n<p data-block-type=\"core\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"8-critical-raw-material-problems-that-lead-to-briquettes-breakage\" data-block-type=\"core\"><strong>8 Critical Raw Material Problems That Lead to&nbsp;Briquettes&nbsp;Breakage<\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\">Over years of on-site investigations and production analysis, it has been found that most cases of briquette breakage are closely linked to raw material characteristics rather than equipment or binder performance.<\/p>\n\n\n\n<p data-block-type=\"core\">The following eight raw material issues are the most common root causes of poor briquette strength and durability.&nbsp;By understanding how these problems arise and affect the&nbsp;briquetting process, producers can take targeted actions to improve&nbsp;briquettes&nbsp;stability and reduce breakage rates.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>1. Uneven or Excessively Fine Particle Size<\/strong><br>Raw materials with poorly graded or overly fine particles struggle to form a stable internal structure. Freshly pressed briquettes may appear smooth, but as drying progresses, uneven shrinkage occurs due to high porosity, leading to cracks and easy breakage during handling or transport.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>2. Unstable Moisture Content<\/strong><br>Moisture fluctuations, whether from inconsistent raw material storage, transport, or absorption, directly affect briquetting&nbsp;and drying. Excess moisture causes warping and cracking during drying, while too little prevents full binder activation, resulting in weakly bonded particles and poorly formed briquettes.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>3. High Impurity Levels<\/strong><br>Raw materials containing impurities such as Cl, S, P, Zn, or Pb can produce surface defects and internal weaknesses. During high-temperature use, these impurities may vaporize or react, compromising structural integrity and increasing environmental compliance risks.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>4. Inconsistent Chemical Composition<\/strong><br>Variation in key chemical components across batches leads to unpredictable&nbsp;briquettes&nbsp;strength and size. Plants may need to frequently adjust equipment or binder ratios, making standardized production difficult and reducing operational reliability.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>5. Presence of Oils or Organic Contaminants<\/strong><br>Some raw materials, especially industrial by-products, contain oils or other organic residues that coat particle surfaces. This prevents effective binder adhesion, resulting in weakly compacted briquettes that are prone to cracking, particularly under high-temperature conditions.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>6. Poor Compatibility with Binders<\/strong><br>Certain raw material surface properties, such as high oil content, the presence of waxes, or reactive impurities, can interfere with binder performance. Even when the binder dosage is carefully optimized, these materials may still produce fragile briquettes. This highlights the importance of selecting binders that are well-matched to the characteristics of the raw materials.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>7. Unstable Supply and Handling Conditions<\/strong><br>Variations in suppliers, inconsistent material quality, and storage or transportation challenges can exacerbate other raw material issues, such as moisture fluctuation or contamination. Unstable supply chains increase the risk of batch-to-batch variation and production disruptions.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>8. High Calcium Oxide (CaO) Content<\/strong><br>Materials with elevated CaO levels are highly hygroscopic. When exposed to moisture, CaO expands, causing internal stresses that lead to self-cracking, surface bulging, or powdering.&nbsp;<\/p>\n\n\n\n<p data-block-type=\"core\">This reduces storage stability and overall briquette yield. If left unaddressed, excessive CaO content significantly lowers production yield and increases material waste.<\/p>\n\n\n\n<p data-block-type=\"core\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"jianjie-binder-solutions-and-service-support-for-high-quality-briquettes\" data-block-type=\"core\"><strong>Jianjie Binder Solutions and Service Support for High-quality&nbsp;Briquettes&nbsp;&nbsp;<\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\">While raw material challenges are often complex and cannot always be fully resolved at the production site, their negative impact on&nbsp;briquetting&nbsp;can be significantly reduced through the right technical approach.<\/p>\n\n\n\n<p data-block-type=\"core\">Jianjie focuses on providing high-performance&nbsp;<a href=\"https:\/\/www.jianjiebinder.com\/zh\/full-guide-on-jianjie-binder-selections-for-briquetting-and-pelletizing\/\" target=\"_blank\" rel=\"noreferrer noopener\">tailored&nbsp;binders<\/a>, designed for&nbsp;different types of raw materials&nbsp;and professional support services to help producers stabilize their cold briquetting processes and improve overall product quality.<\/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=\"1024\" height=\"683\" src=\"https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/MG_9031-1024x683.jpg\" alt=\"Jianjie binder for coal briquetting\" class=\"wp-image-19077\" style=\"width:500px\" srcset=\"https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/MG_9031-1024x683.jpg 1024w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/MG_9031-300x200.jpg 300w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/MG_9031-768x512.jpg 768w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/MG_9031-18x12.jpg 18w, https:\/\/www.jianjiebinder.com\/wp-content\/uploads\/2025\/09\/MG_9031.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\" data-block-type=\"core\">Jianjie Briquetting Binder<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" data-block-type=\"core\"><span><b>How Jianjie Can <\/b><strong style=\"font-weight: bold;\">Help<\/strong><\/span><strong> <strong>Improve&nbsp;Briquettes&nbsp;Performance<\/strong><\/strong><\/h3>\n\n\n\n<p data-block-type=\"core\"><strong>Tailored Binder Formulations<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Custom-designed binders to address specific raw material issues, such as high-zinc EAF dust or powders with oil contamination.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Dynamic Recipe Guidance<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Recommendations for adjusting binder ratios in response to fluctuations in raw material composition, ensuring more consistent performance.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Improved Particle Bonding<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">High-activity binders that enhance adhesion in ultra-fine or high-porosity materials, helping to offset structural weaknesses.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Moisture Tolerance Enhancement<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">Binders formulated to remain effective within a wider moisture range, reducing the risk of cracking caused by uneven water content.<\/p>\n\n\n\n<p data-block-type=\"core\"><strong>Technical Consulting and Support<\/strong><\/p>\n\n\n\n<p data-block-type=\"core\">On-site guidance to help plants optimize handling practices, stabilize supply chains, and standardize quality control procedures.<\/p>\n\n\n\n<p data-block-type=\"core\">By combining targeted binder solutions with process expertise, Jianjie assists customers in minimizing the effects of raw material variability, resulting in stronger, more durable briquettes and more reliable furnace performance.<\/p>\n\n\n\n<p data-block-type=\"core\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"collaborative-approaches-to-improve-briquettes-quality\" data-block-type=\"core\"><strong>Collaborative Approaches to Improve&nbsp;Briquettes&nbsp;Quality<\/strong><\/h2>\n\n\n\n<p data-block-type=\"core\">Briquettes&nbsp;breakage usually results from several raw material issues interacting with each other.
