However, because coal particles do not naturally bond strongly under pressure alone, a suitable <strong><a href=\"https:\/\/www.jianjiebinder.com\/coal-briquette-binder\/\" data-type=\"post\" data-id=\"17514\">coal briquette binder<\/a><\/strong>&nbsp;is often required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" data-block-type=\"core\"><strong>So, what binder is commonly used for coal briquettes in Indonesia?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\" data-block-type=\"core\">There is no single binder suitable for every application. Common options include <strong>cassava starch (tapioca), molasses, sodium silicate (water glass), and composite binders<\/strong>. The right choice depends on the coal properties, briquetting process, required strength, and final application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" data-block-type=\"core\">Let&#8217;s go through the binders together.<\/p>\n\n\n\n<h2 id=\"1-cassava-starch-tapioca\" class=\"wp-block-heading\" data-block-type=\"core\">1.

It is an attractive option because it is relatively easy to obtain, combustible, and generally adds little inorganic ash to the briquette.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" data-block-type=\"core\">However, starch-based binders require appropriate control of <strong>moisture, mixing, and drying<\/strong>. If the formulation or preparation is not suitable for the coal, briquettes may have insufficient strength or become vulnerable to moisture.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" data-block-type=\"core\"><strong>Best suited for:<\/strong>&nbsp;producers looking for a relatively simple, combustible, and locally familiar binder.<\/p>\n\n\n\n<h2 id=\"2-molasses\" class=\"wp-block-heading\" data-block-type=\"core\">2.

Its natural stickiness helps coal particles adhere during forming and can improve the initial strength of briquettes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" data-block-type=\"core\">Molasses can be attractive when it is readily available locally. However, its performance can be affected by moisture and drying conditions. Producers also need to consider handling characteristics, storage stability, and whether the binder is suitable for their specific production process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" data-block-type=\"core\">Therefore, while molasses can work well in some applications, the lowest purchase price does not necessarily mean the lowest overall production cost. Binder consumption, drying requirements, rejected briquettes, and transportation losses should also be considered.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" data-block-type=\"core\"><strong>Best suited for:<\/strong>&nbsp;applications where molasses is readily available and its processing characteristics fit the production line.<\/p>\n\n\n\n<h2 id=\"3-sodium-silicate-water-glass\" class=\"wp-block-heading\" data-block-type=\"core\">3.
