This fluidization completely breaks inter-particulate friction, allowing dry bulk solids such as raw meal, pulverized fly ash, and finished cement powder to behave like a liquid. The fluidized material flows effortlessly down a slight downhill gradient of <strong>4% to 8% (2.5&deg; to 4.5&deg;)<\/strong> under natural gravitational pull, requiring zero internal mechanical propulsion. <\/p>\n<div class=\"w-full grid grid-cols-1 sm:grid-cols-2 gap-4 pt-4 border-t border-gray-100\">\n<div class=\"w-full p-4 rounded-[8px] bg-gray-50 border border-gray-100\"> <span class=\"text-xs font-semibold uppercase tracking-wider text-[#66727d]\">Power Requirement<\/span> <\/p>\n<p class=\"text-lg font-bold text-[#123a63] mt-1\">0.03 &ndash;
