Feeding Raw Material<\/strong><\/p>\n<p>Use a vibration feeding machine, feeding hopper, electromagnetic vibration feeder, belt feeder, wheel loader, or excavator to feed directly. It depends on process capacity and raw material conditions to choose which <a href=\"https:\/\/www.jxscmachine.com\/fr\/categorie\/machine-dalimentation\/\">machine d'alimentation<\/a> to use.<\/p>\n<p><strong>2. Washing &amp; Clay Removal<\/strong><\/p>\n<p>To remove clay, kaolin, and slurry from raw materials, the most commonly used silica sand washers include<strong> drum sand washers, log-type sand washers, spiral sand washers, and grinding sand washers.<\/strong> Silica sand washers, grinding sand washers, and spiral classification sand washers are particularly effective for cleaning silica sand with a particle size of less than 3 millimeters. For larger particle sizes, drum sand washers and log-type sand washers are recommended for cleaning.<\/p>\n<p><strong>3. Primary Sieving to Remove Coarse Waste Sand<\/strong><br \/>\nAfter washing and cleaning the clay, we need to sieve out some bigger waste sand, and the under-screen sand will go to the next <a href=\"https:\/\/www.jxscmachine.com\/fr\/categorie\/separateur-de-gravite\/\">machine de s\u00e9paration par gravit\u00e9<\/a>. This sieving process can use a normal vibration screen or a silica sand high-frequency vibration screen.<\/p>\n<p><strong>4. Gravity Separation to Remove Heavy Minerals<\/strong><br \/>\nIt is for primary silica sand gravity separation to remove heavy minerals, such as ilmenite, hematite, iron, etc. The most common uses of the silica sand separation machine are the <a href=\"https:\/\/www.jxscmachine.com\/fr\/separateur-de-gravite\/table-a-secousses-pour-lor\/\">table \u00e0 secousses<\/a> et le <a href=\"https:\/\/www.jxscmachine.com\/fr\/separateur-de-gravite\/chute-en-spirale\/\">s\u00e9parateur \u00e0 goulotte en spirale<\/a>. It depends on the processing capacity to choose which gravity separation machine. <em>High-capacity plants prefer spiral chutes; smaller setups use shaking tables.<\/em><\/p>\n<p><strong>6. Silica Sand Refining Process Removes Magnetic Minerals<\/strong><br \/>\nAfter silica sand gravity separation, there will still be some percentage of magnetic minerals in silica sand, so we need to remove them using the <a href=\"https:\/\/www.jxscmachine.com\/fr\/categorie\/separateur-magnetique\/\">s\u00e9parateur magn\u00e9tique<\/a><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">.&nbsp;Different<\/span> magnetic minerals will use different Gauss magnetic separators. To remove the iron, you need 1000 gauss. And to remove ilmenite and hematite, a field strength of 8000- 9000 gauss is needed. Different usage of silica sand will require different percentages of magnetic minerals remaining in the final silica sand product.<\/p>\n<p><strong>7. Sieving Out The Requested Size Silica Sand<\/strong><br \/>\nAfter removing magnetic minerals, we will need to sieve out the requested size silica sand, usually using the <a href=\"https:\/\/www.jxscmachine.com\/fr\/classer\/ecran-vibrant\/\">high-frequency vibration screen<\/a>, with a PU screen; the screen mesh size can be customized.<\/p>\n<p><strong>8. Drying<\/strong><br \/>\nAfter sieving out the final silica sand, then drying the sand by drying machine.<\/p>\n<p><strong>9. Packing<\/strong><br \/>\nAfter drying the sand, use a packing machine to pack the final silica sand product, and then you can sell it. The silica sand packing machine is a ton bag packing machine, which can be 0.5T, 1T, 2T, or 3T per bag as requested.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<div id=\"ultimate-heading-2706a5ef5e43ca44\" class=\"uvc-heading ult-adjust-bottom-margin ultimate-heading-2706a5ef5e43ca44 uvc-4463\" data-hspacer=\"no_spacer\"  data-halign=\"left\" style=\"text-align:left\"><div class=\"uvc-heading-spacer no_spacer\" style=\"top\"><\/div><div class=\"uvc-main-heading ult-responsive\"  data-ultimate-target='.uvc-heading.ultimate-heading-2706a5ef5e43ca44 h3'  data-responsive-json-new='{\"font-size\":\"\",\"line-height\":\"\"}' ><h3 style=\"font-weight:normal;color:#dd9933;margin-bottom:10px;\">Silica Sand Plant Flowchart<\/h3><\/div><\/div>\n\t<div  class=\"wpb_single_image wpb_content_element vc_align_center wpb_content_element\">\n\t\t\n\t\t<figure class=\"wpb_wrapper vc_figure\">\n\t\t\t<div class=\"vc_single_image-wrapper   vc_box_border_grey\"><img loading=\"lazy\" decoding=\"async\" width=\"506\" height=\"640\" src=\"https:\/\/www.jxscmachine.com\/wp-content\/uploads\/2018\/05\/How-to-process-silica-sand4.png\" class=\"vc_single_image-img attachment-full\" alt=\"Comment traiter le sable siliceux4\" title=\"Comment traiter le sable siliceux4\" srcset=\"https:\/\/www.jxscmachine.com\/wp-content\/uploads\/2018\/05\/How-to-process-silica-sand4.png 506w, https:\/\/www.jxscmachine.com\/wp-content\/uploads\/2018\/05\/How-to-process-silica-sand4-237x300.png 237w\" sizes=\"auto, (max-width: 506px) 100vw, 506px\" \/><\/div>\n\t\t<\/figure>\n\t<\/div>\n\n\t<div  class=\"wpb_single_image wpb_content_element vc_align_center wpb_content_element\">\n\t\t\n\t\t<figure class=\"wpb_wrapper vc_figure\">\n\t\t\t<div class=\"vc_single_image-wrapper   vc_box_border_grey\"><img loading=\"lazy\" decoding=\"async\" width=\"743\" height=\"605\" src=\"https:\/\/www.jxscmachine.com\/wp-content\/uploads\/2018\/05\/How-to-process-silica-sand5.png\" class=\"vc_single_image-img attachment-full\" alt=\"Comment traiter le sable de silice5\" title=\"Comment traiter le sable de silice5\" srcset=\"https:\/\/www.jxscmachine.com\/wp-content\/uploads\/2018\/05\/How-to-process-silica-sand5.png 743w, https:\/\/www.jxscmachine.com\/wp-content\/uploads\/2018\/05\/How-to-process-silica-sand5-300x244.png 300w\" sizes=\"auto, (max-width: 743px) 100vw, 743px\" \/><\/div>\n\t\t<\/figure>\n\t<\/div>\n<h2 style=\"color: #1e73be;text-align: center;font-family:Alegreya Sans;font-weight:400;font-style:normal\" class=\"vc_custom_heading vc_do_custom_heading vc_custom_1778226777939\" >Silica Sand Processing Equipment Manufacturer<\/h2>\n\t<div class=\"wpb_text_column wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p><strong>JXSC mine machinery factory<\/strong> in China has more than 40 years of professional experience in <a href=\"https:\/\/www.jxscmachine.com\/fr\/solutions\/usine-de-traitement-du-sable-siliceux\/\">silica sand processing plants<\/a>, designs a full set silica sand process flowchart, provides a complete set silica sand washing plant, and can send the engineer to the mine site for equipment installation and commissioning guidance.
