Ø25×230 mm Neodymium Rod Magnet with Mounting Brackets for Turkish Coffee Grinding Lines
Ø25×230 mm Neodymium Rod Magnet with Mounting Brackets for Turkish Coffee Grinding Lines
Key Features
- Fits the feed chute or hopper of a Turkish coffee grinder
- Catches wire, nails and steel fragments before they reach the grinder
- 8,000 Gauss at the tube surface
- Slotted brackets at both ends bolt straight onto the chute wall
- Sealed stainless tube; no power supply needed
- Made to order in other lengths, diameters and Gauss levels
The Ø25×230 mm neodymium rod magnet with mounting brackets, also known as a magnetic rod, magnetic bar or tube magnet, is fitted ahead of Turkish coffee grinders to catch iron and steel in the roasted beans. Its 230 mm magnetic length suits narrow feed chutes and grinder hoppers, and the slotted brackets at both ends bolt directly to the chute wall without a separate housing.

Why Turkish Coffee Grinders Need a Magnet
Turkish coffee is ground to a very fine powder, so stone and steel-burr grinders work with a very small gap. A single nail or a loose rivet entering that gap can chip a burr or score a stone. Sack stitching wire, parts from bucket elevators and bolts forgotten after maintenance can pass through roasting and cooling and reach the grinder. A rod magnet fitted just before the grinder holds these pieces, protecting the grinder and reducing the risk of metal in the packed coffee.
Where to Fit It
- In the feed chute to the grinder, after the cooling tray
- At the inlet of the grinder hopper, where the beans fall
Do not fit the rod at the hot outlet of the roaster. The tube is rated to 80 °C, and beans fall below this temperature after the cooling tray.
Model Code Explained
The code 2TM6S88-K reads as follows: 2T M6 = M6 thread at both ends; S = sealed tube; 8 = maximum 80 °C; 8 = 8,000 Gauss; K = with mounting brackets.
Installation and Cleaning
Bolt the brackets to the chute wall with M6 screws so that the rod lies across the flow and the beans pass over and around it. If the chute is wider than 230 mm, use two rods side by side or our 320 mm version. Ground coffee is oily and leaves a fine film on the tube that can hide captured metal. At the end of each shift, remove the rod, slide the captured metal off the end of the tube with a gloved hand, then wipe the tube clean with a dry cloth. The sealed tube can be rinsed with warm water if needed.
Limits
The rod holds ferromagnetic metals such as iron, carbon steel and tool steel. Austenitic stainless steels (AISI 304 and 316) are not magnetic, or only weakly so, and are not reliably removed; aluminium, brass, glass and stone pass straight through. Do not use the rod above 80 °C. Neodymium magnets are very strong: keep fingers clear when handling the rod near steel, and keep it away from anyone fitted with a pacemaker or other implanted medical device and from bank cards and other magnetic storage media.
Other Sizes and Options
Length, diameter, thread size and Gauss level are made to suit your chute. See our rod magnets with special connections, or read more about rod magnets. Where the magnet must be cleaned without opening the chute, an easy-clean rod magnet or a drawer magnet may suit better. Contact us with your chute width for a quotation.
Frequently Asked Questions
Does the magnet affect the taste or aroma of the coffee?
No. The magnetic field only attracts iron-bearing particles and has no effect on the coffee itself.
Will it catch fragments from worn grinder burrs?
Fragments from carbon steel or tool steel burrs are magnetic and are held on the tube. Stainless steel parts are usually non-magnetic and may not be held.
My chute is a different width. Can you make one to fit?
Yes. Send us the chute width and the direction of flow, and we will size the rod and brackets.
