Introduction:
The series LJT-H underbelt metal detector is a highly capable device designed to detect all types of tramp metal, including both ferrous and nonferrous metals. Its primary purpose is to safeguard crushers and other processing plants from damage caused by the presence of unwanted metal contaminants. The metal detector features a stable construction, making it an ideal choice for demanding mining applications, particularly in quarries and harsh conditions.
The versatility of the LJT-H underbelt metal detector enables its utilization across a wide range of industries and applications.It is widely used in various applications and offers easy operation, adjustable sensitivity and detection levels, and an electronic control panel for efficient monitoring and control.
The series LJT-H underbelt metal detector robust construction ensures durability and reliability, making it suitable for challenging mining applications. With its adjustable sensitivity and detection levels, user-friendly operation,optional electronic control panel, and optional extras, it provides effective protection to crushers and processing plants. The recognition of belt metal joints and its suitability for shallow burden applications further enhance its capabilities.
Installation:
The underbelt metal detector is installed beneath a conveyor belt, allowing it to scan the material as it passes over the detector. The installation process involves securely mounting the underbelt metal detector beneath the conveyor and ensuring proper alignment with the belt. The detector is positioned to cover the full width of the conveyor to maximize the detection area. The installation may require adjustments to accommodate different belt widths and heights. The compact design of the underbelt metal detector allows for installation in limited available spaces, making it ideal for applications with space constraints.
Operation:
Once installed, the underbelt metal detector operates by emitting a magnetic field or electromagnetic waves into the material on the conveyor belt. When tramp metal, such as iron or nonferrous metals, passes through the magnetic field, it disrupts the detector‘s electromagnetic balance, triggering an alarm or activating a signal to alert operators of the presence of metal.
Electronic Control Panel Function Introduction:
The underbelt metal detector is equipped with an electronic control panel that serves as the central hub for monitoring and controlling the metal detection process.
The control panel provides a range of functions, including:
Power Supply: The control panel supplies power to the metal detector unit and associated components.
Sensitivity Adjustment: The control panel allows operators to adjust the sensitivity level of the metal detector, enabling them to fine-tune the detection capabilities based on the type and size of metal to be detected.
Alarm System: The control panel incorporates an alarm system, such as visual indicators, audible alarms, or relay outputs, to immediately notify operators when metal is detected.
Underbelt metal detector electronic control panel is available with a choice of high sensitivity metal detector control panel.
After using high sensitivity metal detector control panel,underbelt metal detector will offer more function in contrast with common electronic control panel.
The main added function is below:
Detection Level Adjustment:
The control panel has multiple product memory and enables operators to set the desired detection level, determining the minimum size of tramp metal that triggers an alarm or signal.
This flexibility ensures optimal performance in different scenarios.
Calibration and Self-Diagnostics: The control panel provides options for calibration and self-diagnostics to ensure the metal detector is functioning correctly and accurately.
Optional extras:
Optional extras are available for the underbelt metal detector to cater to specific needs. One such optional feature is the belt metal joint/splice detector, which recognizes the presence of belt joints or splices. This capability prevents false alarms triggered by the conveyor belt itself, enhancing the accuracy of metal detection.
