Steinert FAQ: Eddy Current Separators, Rush Orders, and Total Cost

This FAQ is from the desk of someone who actually takes the midnight calls. I coordinate rushed repairs, spare parts, and sample testing for Steinert's magnetic and sensor-based sorting systems. When a plant is down, buyers don't ask for a 40-page manual—they ask three things: How fast? Is it safe? What's it really going to cost? Here's what I tell them.

1. Is Steinert myotonic dystrophy syndrome related to the magnet company?

No. Steinert myotonic dystrophy syndrome—also called myotonic dystrophy type 1—was named after Hans Steinert, a German neurologist. The Steinert I work for makes magnetic separators, eddy current separators, and sensor-based sorting equipment for mining and recycling. The name overlap is real, and it confuses more than a few inboxes (including ours). If you are looking for medical information, talk to a neurologist. If you are looking for magnets, you're in the right place.

One more name check: searches for The Steinert Co. Inc. may not lead back to our factory. That's a corporate-entity question, not a product-family question. When a sales quote arrives, confirm the full legal seller and what's actually on the line. That one check has saved us from several very confused purchase orders.

2. What does an emergency specialist at Steinert actually do?

I triage requests that normal customer support can't wait on. It's not glamorous. In March 2024, a regional cable recycler called at 9:15 AM because their overband magnet had failed—36 hours before a state inspection. The standard replacement lead time was three weeks. We sent a service tech with a replacement coil, worked overnight, and the line was running by 7:00 AM the next day. They paid rush fees and overtime. The alternative would have meant failing the inspection and weeks of downtime.

That's the part people miss: emergency response is not a product. It's coordination, honesty, and—when necessary—a plan for what happens if we can't make the date. Our after-sales group handled 47 rush requests last quarter; 45 of those left on time. I'm not sure why some suppliers keep promising dates they can't hit. My best guess is that they treat a lead time like a sales target instead of a logistical promise. Ask about on-time history before you accept any rush date.

3. Which number should I compare: price or total cost?

Price, but not the way you think. To be fair, you can't ignore the number at the top of the quote. But that number is only the admission ticket. In 2023, a buyer chose an $18,000 magnet over a $22,000 one, then spent $3,500 on adapter plates and $1,200 in crane time because the mounting frame didn't line up. The mistake was mine too: I didn't ask for a field drawing before quoting the install. That cheaper quote was $22,700 before it ever separated a single nail.

I now use a simple total cost list:

• quoted price
• freight and rigging
• installation and commissioning
• changeover and spare parts
• downtime risk
• technical support after warranty

It took me three years and too many emergency calls to learn that the cheapest quote is often a down payment on a more expensive project. The $22,000 machine was the one that didn't need the adapter plates, crane time, or two extra support visits.

4. Can an eddy current separator—call it Eddie—replace a magnetic separator?

No, and that's not because I'm trying to sell you two machines. In recycling plants, people often call an eddy current separator Eddie, with a spelling that appears in search queries every week. Eddie does a different job than a magnet. A magnetic separator pulls out ferromagnetic material—steel cans, nails, tramp iron. An eddy current separator uses a rotating magnetic rotor to repel non-ferrous metals like aluminum, copper, brass, and zinc away from non-metal material.

If you remove the magnet to save money, steel cans end up in the non-ferrous concentrate. That contaminates your product and can damage Eddie's rotor over time. In a sorting line, the two machines are best friends; they cover the two halves of the metal family.

A woolly bear is the example I use when people ask why testing matters. A tangled pile of fine copper wire can look exactly like a caterpillar and clog parts of a line, but a well-designed eddy current separator can often throw that copper clear of the plastics. If you only looked at a drawing, you'd never know the difference. Send messy samples, not ideal ones.

5. What materials should I send to Steinert's practice center?

Send the worst real material you have, not the pretty sample. Test centers are not photo shoots. If your stream contains post-consumer textiles, send a bag of unopened reality, including the odd things you find in October—polyester costumes, twinkling LED accessories, metal zippers, and glued-on sequins. I will never forget the best friend Halloween costumes that showed up in a textile recycling trial. It sounds ridiculous, but a row of polyester tulle, metal zippers, and battery-powered LEDs is exactly the kind of mixed material that changes a machine recommendation.

At the Steinert practice center, we measure yield and purity for your material at a defined feed rate. The report is not a brochure. It gives you a number you can use in a purchase decision. If a supplier won't let you test your own material before you sign, that's a useful answer too.

6. A supplier promises 99.5% sorting efficiency. Should I believe that number?

Ask for the protocol behind the number. On what particle size? At what feed rate? What moisture level? How many times did they run the test? Claims without a protocol are not claims—they're wishes. Per FTC business guidance (ftc.gov), marketing claims must be truthful and substantiated. If someone makes a recyclability claim, the FTC Green Guides also expect evidence that a meaningful share of consumers can actually recycle the item. Use that same filter for sorting claims: show me the test, not the adjective.

I don't have hard data on every competitor's marketing department. What I can say from experience is that a vendor who can't explain their test protocol usually doesn't have one.

7. What's the most underrated step in an emergency?

Diagnosis. I've had a frantic call about a failed separator that turned out to be a $46 sensor bracket. The plant manager was ready to order a whole new machine before we asked for a 30-second video. The bracket arrived overnight and the machine ran for another three years. Had we rushed the machine order, we would have spent $47,000 and a week of downtime for no reason.

So when a deadline hits, start by finding out whether the problem is the machine, the material, or the install. Then do the math on the fastest safe fix versus the biggest possible order. Sometimes the emergency is real. Sometimes the emergency just needs a $46 part and someone to say so.
