Made For Rough Industrial Applications
The MPI SHARK® BIG Metal Detector is a heavy-duty, large-aperture detection system engineered to inspect oversized products and bulk materials for metal contamination in rugged industrial environments. Designed for wood processing, paper recycling, rubber bales, and heavy plastics applications, the SHARK® BIG is built to detect ferrous, non-ferrous, and stainless-steel contaminants in dense, irregularly shaped, or high-volume loads. Its reinforced frame, customizable aperture sizes, and advanced signal processing ensure accurate contaminant detection while withstanding the demanding conditions of bulk handling facilities. Whether mounted over or around conveyor belts, the SHARK® BIG helps protect downstream equipment, reduce maintenance costs, and ensure compliance with quality assurance programs.
Benefits of the BIG Metal Detector From Magnetic Products, Inc
-
Oversized Tunnel Aperture for Large Products
It accommodates massive and irregular materials like logs, bales, or bulk scrap with aperture widths up to several meters, making it ideal for heavy-duty applications.
-
High-Penetration Signal Processing
Advanced digital technology provides deep detection sensitivity through dense or conductive products, including wet wood, compressed paper, and rubber.
-
Reinforced, Vibration-Resistant Design
Built with a rugged, mechanically stable frame and shock-resistant housing to ensure long-term performance in high-impact environments.
-
Multi-Metal Detection Capability
It simultaneously detects ferrous, non-ferrous, and stainless-steel contaminants, even under challenging conditions involving large loads and material effects.
-
Wide Conveyor Integration Flexibility
It installs easily over or around belt conveyors and is compatible with high-speed, high-capacity lines in the wood, recycling, and material recovery industries.
-
Easy-To-Use Control System
Includes a user-friendly interface with auto-teach calibration, reject signal outputs, data logging, and multilingual menu options.
-
Weather-Resistant and Sealed Construction
Optional IP65 or IP69K enclosures are available for outdoor, dusty, or washdown environments, and they are ideal for mills and open-air recycling facilities.
-
Improved Safety and Equipment Protection
Early tramp metal detection prevents costly damage to shredders, grinders, saws, and other downstream equipment, increasing system uptime.
BIG Metal Detector Product Details
The SHARK® BIG Metal Detector operates as an inline detection system positioned around or above a conveyor carrying large, dense products. As materials pass through the oversized tunnel aperture, the system generates a balanced electromagnetic field that envelops the entire conveyor load.
When a piece of metal—ferrous, non-ferrous, or stainless steel—enters the detection zone, it disrupts this electromagnetic field. The disruption is instantly identified by the detector’s digital signal processor, which evaluates the disturbance and compares it to stored product compensation profiles.
Upon confirmation of contamination, the system triggers an alarm, stops the conveyor, or activates a reject signal (depending on the integrated control logic). Operators can then isolate the contaminated section or divert the load for further inspection or removal. The SHARK® BIG adapts to harsh environmental conditions and variable product characteristics to ensure consistent performance and minimal false rejects.
