Metal Detection for the Timber Industry
Metal detection to insure that incoming wood is free of contaminants, to prevent damage to expensive saw blades and make sure that wood boards, LVL, OSB, plywood, paperboard and other products are perfect quality.
WE PROTECT YOUR MACHINES
CASSEL has been specialising in metal detection for the timber industry for 25 years. Our METAL SHARK® systems are perfectly suited to inspecting boards as well as tree trunks. They are sturdy, stable and sensitive – providing optimum protection for your products and machines.
We love to protect your machines, your products, your customer.
All-rounders: Tunnel metal detectors
Tunnel metal detectors are particularly suitable for installation in conveyor belts, vibratory conveyors or trough channels.
METAL SHARK® BIG and METAL SHARK® BIG pba are specially designed for metal inspection of wood, chipboard or OSB boards. They can be used to monitor delivered co-products and thus protect chippers, shredders, flakers or mills. METAL SHARK® TU is an ideal solution to monitor sawdust or wood shavings for wood chipboard and thus protect the expensive presses.

The specialists: Round and octagonal openings
METAL SHARK® OCTA or METAL SHARK® BIG RD offer optimum protection for saws and saw frames when processing entire tree trunks. They reliably find the smallest metal particles on and deep inside large diameter logs – even at high conveying speeds. Thanks to the octagonal or round opening, they can be ideally integrated into trough or troughed conveyor belts.
METAL SHARK® OCTA and METAL SHARK® BIG RD detectors, like all METAL SHARK® detectors, have a very robust design and, with the appropriate sealant, can withstand extreme weather conditions and low temperatures.
Precision work: Multi-segment detectors
Multi-segment metal detectors have been developed for high precision and most accurate location of metal contaminants. Many individual sensor plates are mounted next to each other. This segmental design enables a consistently high detection accuracy even with very wide products. Each sensor individually detects possible metal contaminations and their position. This way, in case of contamination, as little valuable product material as possible is rejected.
The economical alternative: Single or tandem probes
In case of low bulk height, single-plate metal detectors (so-called under belt coils or under belt probes) like the metal detectors SQ or QLC can be an easy to install and inexpensive alternative to tunnel detectors. They are stable and weatherproof and simply installed under belt or vibratory conveyors. Their accuracy is a little less than that of detectors that detect the product completely from all sides, but this is quite sufficient for many applications. A possible application is the inspection of wood chips for chipboard production. If the height of a product is too high, a second probe can be mounted above the belt (tandem version).
