Your line can use that signal to sound an alarm, stop the belt or trigger another action. The LJT-B does not remove metal by itself, so removal needs a separate manual, reject or magnetic-separation method.<\/p>\r\n<\/div><\/section>\r\n<section class=\"cl-soft\" id=\"quick-fit\"><div class=\"cl-inner\"><div class=\"cl-eyebrow\">Where It Fits<\/div><h2>Where does the LJT-B fit on a conveyor?<\/h2><p class=\"cl-answer cl-fit-lead\">Use the LJT-B when unwanted metal may travel with bulk material on a belt conveyor and could damage crushers or other equipment farther down the line.<\/p>\r\n<div class=\"cl-grid-3\">\r\n<div class=\"cl-card\"><h3>Find unwanted metal on the belt<\/h3><p>Use the LJT-B when metal may travel with bulk material on a belt conveyor. The detector can then send a signal for the line to respond.<\/p><\/div>\r\n<div class=\"cl-card\"><h3>Protect equipment farther down the line<\/h3><p>Place the detector before crushers or other equipment that metal could damage. This gives the line time to alarm, stop or take another linked action.<\/p><\/div>\r\n<div class=\"cl-card\"><h3>Connect detection to the action you need<\/h3><p>Tell us what should happen after detection: alarm, conveyor stop, marker, bypass or another automatic action. Engineers often call this linked control an interlock.<\/p><\/div>\r\n<\/div><p class=\"cl-note cl-listed-apps\">Listed application industries include thermal power, cement, papermaking, mining, forestry, environmental protection and building materials. The setup still needs to match the real conveyor and target metal.<\/p><\/div><\/section>\r\n<section class=\"cl-soft\" id=\"principle\"><div class=\"cl-inner\"><div class=\"cl-eyebrow\">How It Works<\/div><h2>How does the LJT-B detect unwanted metal?<\/h2>\r\n<p class=\"cl-answer\">The detector watches the sensor signal while material passes through the sensing area. Metal changes that signal. The controller checks the change with phase-shift and correlation detection, and the sensitivity can be adjusted. It also uses anti-interference processing to reduce unwanted signal effects from nearby sources.<\/p>\r\n<div class=\"cl-grid-3\">\r\n<div class=\"cl-card\"><div class=\"cl-kicker\">01 \u2014 Sense<\/div><h3>Let the material pass through the sensing area<\/h3><p>The detector frame sits around the belt.

It also has a 1\u201310 second delayed-release setting before the output resets.<\/p><\/div>\r\n<\/div><\/div><\/section>\r\n<section id=\"performance\"><div class=\"cl-inner\"><div class=\"cl-eyebrow\">What Affects Detection<\/div><h2>What can change detection sensitivity on your conveyor?<\/h2>\r\n<p class=\"cl-answer\">Belt width tells you which frame size to start with. Actual detection depends on the target metal, material depth, belt construction, conveyed material and nearby equipment.<\/p>\r\n<div class=\"cl-grid-3\">\r\n<div class=\"cl-card\"><h3>Target metal<\/h3><p>Tell us what metal object must be detected and the smallest test size you want to use. Its size, shape, material and position can change the signal.<\/p><\/div>\r\n<div class=\"cl-card\"><h3>Material depth on the belt<\/h3><p>Tell us the normal and maximum depth of material on the belt. Engineers call this burden depth. A deeper load can make the target harder to detect because the metal sits farther from the sensing area.<\/p><\/div>\r\n<div class=\"cl-card\"><h3>Belt construction<\/h3><p>Splices, clips, steel cords and other metal parts in the belt can affect the signal. An optional splice detector is available, so send us the exact belt construction.<\/p><\/div>\r\n<div class=\"cl-card\"><h3>Nearby equipment<\/h3><p>Steelwork, motors, cables and magnetic equipment can disturb the signal. Send us the layout so we can check more than just the detector frame size.<\/p><\/div>\r\n<div class=\"cl-card\"><h3>Material condition<\/h3><p>Wet material, material that carries electrical current, high mineral content and changing product conditions can affect the signal. If the material is difficult, define the test condition first. Then set the pass\/fail target.<\/p><\/div>\r\n<div class=\"cl-card\"><h3>Required action<\/h3><p>Tell us what the line should do after detection.

Tell us the target metal and smallest test size you need. We do not publish one universal minimum detection size because the result depends on the material, belt and test condition.<\/p><\/details>\r\n<details><summary>Does the LJT-B remove the detected metal?<\/summary><p>No. The LJT-B is a detector and control device. After detection, the line can alarm, stop or trigger another linked action. Physical removal requires a separate manual, reject or magnetic-separation method.<\/p><\/details>\r\n<details><summary>Can the LJT-B be installed on an existing conveyor without cutting the belt?<\/summary><p>Yes. The LJT-B can be installed around an existing belt conveyor without cutting the belt. This type of upgrade is often called a retrofit.<\/p><\/details>\r\n<details><summary>Which conveyor belt widths are covered by the LJT-B model range?<\/summary><p>The listed models cover 500, 650, 800, 1000, 1200, 1400, 1600, 1800 and 2000 mm belt widths. We also check the available mounting space around your conveyor before finalizing the setup.<\/p><\/details>\r\n<details><summary>How do belt splices affect detection?<\/summary><p>Metal splices or clips can affect the detector signal. An optional splice detector is available. Send us the splice or clip type and belt construction so we can include it in the setup.<\/p><\/details>\r\n<details><summary>Can the LJT-B be installed near a magnetic separator?<\/summary><p>Yes, it can be considered on a line that also uses magnetic separation. The spacing, nearby steelwork and magnetic field still need to be checked. Send us the line drawing and equipment spacing with your quotation request.<\/p><\/details>\r\n<details><summary>What should I send for an LJT-B quotation?<\/summary><p>Send the material, target metal, belt width, material depth, conveyor speed, belt construction and splice type.
