How to Sell a Used Industrial Coffee Grinder (Ditting, Mahlkönig, MPE and More)

An industrial coffee grinder is easy to overlook when a roastery changes shape. The roaster gets the attention, and the grinder sits in the packing room doing its job. But a well-kept Ditting, Mahlkönig or MPE grinder has a real buyer waiting for it. If you want to sell a used industrial coffee grinder, the good news is that buyers in this category know exactly what they need. The catch is that they ask very specific questions about burrs, rolls, power and throughput.

This guide covers how to sell a used industrial coffee grinder in every tier. That runs from shop grinders that bag 60 pounds a day to roller mills that feed a packaging line. It builds on our 7-step guide to selling a used coffee roaster, so pricing, negotiation and payment stay brief here. The focus is on what changes when the machine grinds instead of roasts.

Key Takeaways

• Buyers group grinders into three tiers: shop burr grinders, industrial disc grinders and roller mills. Name your tier in the first line of the listing.
• Power decides your buyer pool. State voltage, phase and amps straight from the motor plate.
• Burr or roll condition is the first mechanical question. Service dates and spare burrs answer it fast.
• A short video of the grinder running with beans, plus a photo of the grind, does more than any written description.
• Shop grinders ship on a pallet. Disc grinders and roller mills often need a crate and a forklift at both ends.
• Grinders sell well alongside a roaster or packaging line, because many buyers are building a whole production room.

What Counts as an Industrial Coffee Grinder?

An industrial coffee grinder is built to grind roasted coffee in bulk, for retail bags, wholesale accounts or a packaging line. It is a different machine from the espresso grinder behind a cafe bar. Most fall into three tiers.

• Shop and bulk burr grinders grind into a bag on demand. Think Ditting KR1203 and KFA1403, Mahlkönig EK43, Guatemala and GH2. Many are built for 60 pounds a day or more.
• Industrial disc grinders run continuously at higher output. The MPE GPX and GPC-140, Mahlkönig DK15 and DK27, and the Ditting KF1800 sit here.
• Roller mills (granulizers) crack beans between corrugated rolls in two or three stacked sections. MPE and its older Gump models, Probat UW mills and Petroncini MCR units lead this tier.

CoffeeTec's seller program focuses on roastery and production equipment, so this guide covers those three tiers. Shop the industrial and commercial coffee grinder collection to see how buyers compare them side by side.

Here is what sellers actually bring us. From June 2022 to October 2026, sellers submitted 50 shop and industrial grinders to CoffeeTec from the four brands that lead this category. MPE (including Gump) led with 20, Mahlkönig followed with 18, and Ditting and Probat had 6 each. More than half of those 50 machines, 27 in all, ran on three-phase or 380 to 480 volt industrial power. That one detail shapes who can buy your grinder, so it gets its own section below.

Who Buys a Used Industrial Grinder?

Knowing your buyer tells you what to put in the listing. Most used industrial grinders go to one of four groups:

• Growing roasteries moving from an EK43 or Guatemala up to a dedicated bagging grinder like a Ditting KFA1403.
• Wholesale and private-label roasters who need a disc grinder that runs all shift without overheating.
• Packaging and co-packing operations that pair a roller mill with fillers, VFFS baggers or K-Cup lines.
• Retail roasters and grocery programs that grind to order at the counter.

Each group reads the same listing for different facts. A roastery adding retail bags wants burr size and hopper capacity. A co-packer wants pounds per hour and grind range. Give both, and you answer most first questions before the phone rings.

What Buyers Check First, by Grinder Type

Every tier gets a different first question. Answer it in your listing and you skip a round of back-and-forth.

How to Sell a Ditting Grinder

Ditting shop grinders are workhorses in retail roasteries, and buyers know the model numbers well. Browse the Ditting coffee grinder collection to see how current listings describe them.

Read the model off the data plate

The KR1203, KFA1403, KR1403 and KF1800 sound alike but suit very different buyers. Photograph the data plate and use the exact model in your title. A buyer looking for 120 volt power will skip a 1403 the moment they see the model, and that saves you both a call.

Give the burr history

Say when the burrs were last replaced, or that they are original. If you have a spare set, list it. One Ditting seller noted a fresh cleaning and new burrs right in the form. That single line answered the buyer's biggest question.

Show the bagging parts

The shake plate, bag clamp and paddle start take the most wear on a shop grinder. Photograph each one. Name small faults plainly, like a torn rubber connector or a frayed cord. Buyers will fix those. What they won't accept is finding them after delivery.

How to Sell a Mahlkönig Grinder

Mahlkönig covers the widest range of any brand in this guide. It runs from the EK43 on a roastery counter to the DK27 in a production plant. The Mahlkönig grinder collection shows how buyers see that lineup.

Separate shop models from industrial models

An EK43, Guatemala or GH2 buyer wants grind quality and hopper size. A DK15 or DK27 buyer wants output. Mahlkönig rates the DK15 at roughly 105 to 200 kg per hour, so lead the listing with that figure and your power specs.

Track the hours, not just the years

A low-hour industrial grinder stands out. One DK15 seller gave months in service, hours per week and a weekly calibration and burr cleanout routine. Numbers like that turn "lightly used" into a fact a buyer can check.

List the stand, trolley and hopper

Industrial Mahlkönig grinders often come with a stainless trolley or stand and an oversized hopper. A DK-15LS submitted to CoffeeTec came with a trolley and a hopper holding about 40 pounds of beans. Buyers count those parts when they compare listings.

How to Sell an MPE Disc Grinder, Roller Mill or Probat Mill

Disc grinders and roller mills serve a smaller, more technical buyer pool, mostly roasteries feeding a packaging line. These buyers read a listing like an engineer reads a spec sheet.

Describe the rolls and sections

State how many grinding sections the mill has and the condition of the rolls. Worn rolls crush instead of cut, and buyers know it. If the rolls were reconditioned, give the date. MPE runs an exchange program for granulizer heads and rolls, and paperwork from it adds real value to a used mill.

Disclose any reconfiguration

Mills get changed over their life. A pair of MPE IMD 8888 mills listed with CoffeeTec had one unit reconfigured into a three-section mill with coarser rolls. The seller said so up front, and that kind of disclosure keeps a deal alive at inspection.

List the support equipment

Water-cooled rolls, a normalizer, chillers, a magnet and a conveyor all change the buyer's install plan. That IMD 8888 listing included a Chain-Vey conveyor and two chillers. A sold MPE GPC-140 in CoffeeTec's sold listings archive came with a hopper magnet and two spare grinding discs. Extras like these are worth a line each.

Rebuilt Probat mills

Probat UW mills often stay in service for decades and get rebuilt more than once. If yours has been rebuilt, say who did the work and when. Give the rated capacity in kilograms per hour too.

MPE disc grinders (GPX and GPC-140)

MPE's disc grinders are the most common industrial grinders sellers bring us. Give the disc size (5.5 inches on the GPX, 7.1 inches on the GPC-140) and the date the discs were last changed or re-sharpened. MPE discs can be re-sharpened, so a re-sharpening invoice reads as care, not wear. One GPC-140 seller noted the disc was changed once a year.

Power: The Detail That Decides Your Buyer Pool

Power is where industrial grinder sales most often stall. Two sellers who came to CoffeeTec gave the same reason for selling: their building could not run three-phase power. Their grinders were fine. The site was the mismatch. One of them, a 2017 MPE GPX, has since sold through CoffeeTec to a buyer set up for three-phase.

The same thing can happen in reverse with your buyer. So put these specs in the first lines of your listing, copied from the motor plate. On an MPE GPX, for example, the power specs sit on the motor, not on the maker's plate on the hopper:

• Voltage (120, 208, 220 to 240, 380 or 480). If the plate lists two ranges, like 208-230/460, give both
• Single-phase or three-phase
• Amps and hertz (50 or 60 Hz)
• Motor horsepower, if shown

A buyer on the right power reads on. A buyer on the wrong power can price a phase converter or an electrician before they call. Either way, you get a better conversation.

Prepare Your Grinder Before You List

Grinder buyers want facts they can check. Work through these steps before you fill in the seller form.

1. Purge and clean it. Run cleaning tablets or a purge batch, then vacuum the grind chamber, chute and hopper. Old coffee oil photographs badly.
2. Run it with beans. Grind at coarse and fine settings. Note the setting numbers so the buyer sees the full range works.
3. Photograph the grind. A close photo of the grounds at each setting shows particle consistency. For a roller mill, a recent sieve or Ro-Tap result is even better.
4. Shoot both plates and the burrs or rolls. Buyers use the maker's plate to confirm model and year, and the motor plate to confirm power. Burr or roll close-ups show wear.
5. Film a walk-around under one minute with the grinder running and beans going through.
6. Gather the paperwork: manual, service invoices, burr or roll replacement dates and any wiring diagram.
7. Measure and weigh it, with and without the hopper, and note whether it needs a forklift.

Then pick an honest condition grade. Every used item on CoffeeTec is described against its used equipment condition guidelines, from As-Is through Like New. That way the grade in your listing matches what the buyer finds.

Pick your grinder type below and fill in what you know. The builder writes a listing title in the format buyers search for and shows which questions a buyer will still ask.

Shipping an Industrial Coffee Grinder

Size changes everything. A KR1203 travels on a small pallet. A disc grinder over five feet tall needs a crate and a forklift at both ends. The figures below are approximate and come from recent seller submissions to CoffeeTec. Always weigh and measure your own unit.

Remove the hopper before crating if the design allows it. That often brings a tall grinder down to a standard pallet height. For a roller mill, plan the chillers, conveyor and control panel as separate pieces, and label every cable before you disconnect it.

Sell the Grinder With the Rest of the Line

Many industrial grinders come out of a roastery that is closing, moving or replacing its whole production room. A buyer setting up a packaging line would rather buy a matched grinder, filler and sealer than hunt for each one. If you are selling several machines, our guide to selling a complete coffee roastery covers how to package them. On CoffeeTec's seller form, list the main machine first and add the grinder under "Other Included Equipment."

What Is a Used Industrial Grinder Worth?

Value comes down to brand, tier, hours or pounds ground, burr or roll condition, power and what's included. A low-hour disc grinder with spare discs and a magnet holds value far better than a bare unit with unknown history. Check current and sold listings for the same model, then read how much a used coffee roaster is worth for the factors that move the number. Most of them apply to grinders the same way.

The fastest way to lose value is a vague listing. "Works great" with no burr date and no power specs reads as a risk. Our list of mistakes to avoid when selling used coffee equipment covers the rest.
