Non-magnetic material leaves normally; iron stays with the belt longer and drops into a separate path.<\/div><\/details>\r\n<details><summary>What is the difference between a magnetic pulley and a magnetic drum separator?<\/summary><div class=\"cl-faq-answer\">A magnetic pulley works at the conveyor head. A magnetic drum is a separate separator with its own feed and discharge. We choose from your process layout and material presentation.<\/div><\/details>\r\n<details><summary>Magnetic pulley or suspended magnet \u2014 which one should I use?<\/summary><div class=\"cl-faq-answer\">Use a magnetic pulley when the head is the right separation point. Use a suspended magnet when iron should be removed from above the belt before discharge.<\/div><\/details>\r\n<details><summary>Can a magnetic pulley replace my existing conveyor head pulley?<\/summary><div class=\"cl-faq-answer\">Yes, in some projects. We first confirm pulley size, shaft, bearings, drive, belt conditions and discharge space. We do not assume a size-for-size swap.<\/div><\/details>\r\n<details><summary>Does higher Gauss mean better magnetic separation?<\/summary><div class=\"cl-faq-answer\">No. Gauss is one reading at one point. Working distance, target iron, material depth, belt speed, feed condition and discharge layout also affect separation.<\/div><\/details>\r\n<details><summary>What RCTG magnetic pulley sizes are listed in the reference range?<\/summary><div class=\"cl-faq-answer\">The RCTG reference range covers drum diameters from 320 to 1250 mm and face lengths from 500 to 1800 mm. The 16 listed models use a reference maximum belt speed of 2.5 m\/s. Final model selection still depends on the conveyor, material depth and target iron.<\/div><\/details>\r\n<details><summary>What magnetic strength is available for the RCTG family?<\/summary><div class=\"cl-faq-answer\">The 16 listed RCTG models show approximately 1500 to 1800 GS at the stated reference condition. The RCTG published product family specifications also notes that other magnetic-strength versions from 800 to 8000 GS can be specified when ordering. Gauss is a configuration value, not a direct separation-efficiency rating.<\/div><\/details>\r\n<details><summary>What information should I send for magnetic pulley selection?<\/summary><div class=\"cl-faq-answer\">Start with material, target iron, throughput and process condition. For a retrofit, add belt details and the current head-pulley drawing or dimensions if available.<\/div><\/details>\r\n<\/div>\r\n<\/div>\r\n<\/section>\r\n<section class=\"cl-section cl-alt\" id=\"rfq\">\r\n<div class=\"cl-inner\">\r\n<div class=\"cl-section-title\">\r\n<div class=\"cl-kicker\">Initial RFQ<\/div>\r\n<h2>Send Us These Four Details First<\/h2>\r\n<p>You do not need a finished specification before contacting us.
