Whole Log Metal Detector for Forestry Applications and Saw Mills.

Industrial application: Conveyor Feed, Forestry

For whole log inspection in forestry and saw mills, 1300-2200 mm opening

The Metal Detector OCTA is made for rough industrial applications at saw mills and in forestry operations. Designed specially for big products such as wood logs. The machine is typically installed in a half pipe or U-shaped conveyor.

The Metal Detector OCTA is available with aperture diameter of 1300 to 2200 mm (51,2 to 88 inch).

Available digital controllers: METAL SHARK® 1,  METAL SHARK® 2A

Features & Benefits of Metal Detector OCTA

New Metal Detector Protects Machinery and Reduces Rejection of Valuable Logs

The wood industry has been spoilt for choice: Either it has protected its machinery while rejecting valuable logs or has had to accept excessive downtime. Cassel Messtechnik GmbH puts an end to this with its new metal detector: METAL SHARK® OCTA SPD.

Conventional metal detectors cannot find metal parts of the same size throughout the log. Example: When set up to find a bombshell inside a log, the metal detector would find tiny nails on the outside of the log which do not pose a danger to a saw or a knife. So, actually, the log could be processed.

When adjusted not to find these tiny nails, however, conventional metal detectors do not find dangerous metal parts inside the log that do cause damage. Therefore, one is spoilt for choice: Either one protects machinery while rejecting valuable logs or one has excessive downtime.

The new Cassel OCTA metal detector is different. It detects outside and inside the log metal objects of similar size. When you set it up to detect a bombshell, it detects a bombshell. Tiny nails are not detected. This way, only logs posing serious danger to the machinery are rejected. The forest industry saves money because it processes and sells all valuable logs, decreases sharpening costs and reduces downtime to a minimum.

“One hour of downtime costs at least 5,000 euros,” the technical manager of a big German panel board factory knows. When being asked how valuable a Cassel metal detector is he answers: “We could not run our OSB production line without the Cassel METAL SHARK®.”

The standard size of the METAL SHARK® OCTA SPD is 1800×1800. It can be supplied in other sizes and with additional options like a Xenon warning flash lamp or an acoustic alarm. It is specially constructed for the rough environments of the forest industry.

The METAL SHARK® OCTA SPD 1800×1800 has a homogeneous area of 1000 mm in the center of its aperture. There it can find metal pieces the size of a metric nut M6-M8. The sensor field is more than ten times stronger than that of conventional metal detectors. Hence, interference from other machinery is strongly reduced.

The metal detector comes with a control unit featuring the newest digital technology. This is very easy to handle. One can say that the service technician is already included. “Once set up, the metal detector has run for three years now not needing to be adjusted again,” the technical manager, quoted above, explains.
