Commercial Coffee Grinder for Sale: What to Know Before You Buy
If you're shopping for a commercial coffee grinder, whether for a new cafe, a restaurant, or even a serious home setup, the market has a huge range of options from $300 refurbished units to $5,000+ flagship models. I've helped set up grinders in three different coffee shops and bought two commercial units for my own use over the years. The difference between picking the right grinder and the wrong one can mean thousands of dollars in wasted coffee, slower service, and unhappy customers.
I'll walk you through the types of commercial grinders available, what to look for when buying new versus used, the price ranges you can expect, and the brands that have earned their reputation in commercial settings. Whether you're opening your first shop or upgrading existing equipment, this guide will help you make a smart purchase.
Types of Commercial Coffee Grinders
Commercial grinders fall into a few distinct categories, and the type you need depends entirely on your brewing method and volume.
On-Demand Espresso Grinders
These are the most common commercial grinders. They sit next to the espresso machine and grind a fresh dose directly into the portafilter when you push a button. Brands like Mazzer, Eureka, Mahlkonig, and Ceado dominate this space.
Key features to look for: - Burr size: 64mm is entry-level commercial, 75mm is mid-range, and 83mm+ is high-volume - Dosing method: Timed (grind for X seconds) or gravimetric (grind to X grams by weight) - Speed: Measured in grams per second. High-volume shops need 3+ g/s - Retention: How much coffee stays in the grinder between doses. Lower is better for quality and waste reduction
Bulk/Batch Grinders
These grind larger quantities at once for drip brewers, cold brew, or pre-ground retail bags. They have bigger hoppers, faster motors, and grind at coarser settings. The Bunn G series and Mahlkonig Guatemala are popular in this category. If your cafe serves batch drip coffee alongside espresso, you'll likely need one of these in addition to your espresso grinder.
Shop Grinders (Retail Grinding)
These are the grinders you see in grocery stores and coffee shops where customers can grind whole beans to take home. They're built for durability and ease of use, with simple grind-size selectors and large hoppers. The Grindmaster 810 and Bunn G3 HD are industry standards.
New vs. Used: Where the Deals Are
Commercial coffee equipment depreciates quickly, and grinders are no exception. A two-year-old Mazzer that retailed for $2,000 might sell for $600-800 when a cafe closes or upgrades. This creates real opportunities for buyers who know what to look for.
Buying New
New commercial grinders come with full warranties (typically 1-2 years), fresh burrs, and no wear on the motor or bearings. You pay full price, but you know exactly what you're getting.
Typical price ranges (new): - Entry commercial (64mm burrs): $800-1,500 - Mid-range (75mm burrs): $1,500-3,000 - High-volume/flagship (83mm+ burrs): $3,000-5,500
Buying Used or Refurbished
Used commercial grinders are everywhere. Cafes close, upgrade, or switch brands regularly. Sources include restaurant equipment dealers, online marketplaces, coffee equipment forums, and sometimes directly from roasters who've updated their training labs.
What to inspect on a used grinder: - Burr wear: Remove the burrs and check for smooth spots, chips, or uneven edges. Replacement burrs cost $50-150 depending on the brand and size - Motor health: Run the grinder empty. It should hum smoothly without grinding noises, clicking, or vibration - Dosing mechanism: Test the timer or gravimetric system for consistency across 10 doses - Adjustment collar: Should move smoothly without jumping, catching, or excessive looseness - Electrical: Check the cord, plug, and any visible wiring for damage. Commercial kitchens are tough environments
A used grinder with worn burrs but a healthy motor is a great buy. You replace the burrs for $50-150 and have a machine that performs like new for a fraction of retail price.

Brands Worth Considering
After working with commercial grinders across multiple shops, these are the brands I trust.
Mahlkonig
The gold standard for specialty coffee shops. Their EK43 redefined commercial grinding, and the E65S and E80 are top picks for espresso. Expensive, but the build quality and grind consistency justify the price for busy shops. Parts and service are widely available.
Mazzer
Italian-made, practically indestructible, and the most common commercial grinder you'll find on the used market. The Super Jolly, Major, and Robur models have been cafe staples for decades. Parts are cheap and easy to source. The newer Mazzer ZM and Kold series bring modern features to their lineup.
Eureka
Growing fast in the commercial space. Their Atom, Olympus, and Helios models offer excellent grind quality with lower noise than most competitors. Italian manufacturing with strong quality control. Good value compared to Mahlkonig at similar performance levels.
Ceado
Less well-known but highly respected among specialty coffee professionals. Their E37S and E37Z are popular in competition settings. Ceado grinders tend to produce very low retention and clean, consistent grinds.
What Size Burrs Do You Actually Need?
This is the most common mistake I see new cafe owners make: buying a grinder that's either too small or too large for their volume.
64mm Burrs
- Good for: Low-volume cafes (under 100 drinks/day), home prosumer use
- Examples: Mazzer Super Jolly, Eureka Mignon XL
- Limitations: Slower grinding speed, burrs wear faster at high volumes
75mm Burrs
- Good for: Medium-volume cafes (100-300 drinks/day), most specialty shops
- Examples: Mahlkonig E65S, Eureka Helios 75
- Sweet spot: Fast enough for rush periods, precise enough for specialty quality
83mm+ Burrs
- Good for: High-volume shops (300+ drinks/day), drive-through operations
- Examples: Mahlkonig E80, Mazzer Robur, Eureka Olympus
- Advantages: Fastest grinding speed, longest burr life, best heat management
If you're opening a new cafe and aren't sure about volume, 75mm burrs give you the most flexibility. You can handle morning rushes without bottlenecking, and the burrs last longer than 64mm sets under moderate use.

Total Cost of Ownership
The purchase price is only part of the equation. Factor in these ongoing costs:
- Burr replacement: $50-200 per set, every 6-18 months depending on volume
- Cleaning supplies: Grinder tablets, brushes, about $100/year
- Electricity: Commercial grinders draw 250-500 watts, but only during grinding
- Calibration time: Every new bag of beans requires dialing in, which wastes 20-30 grams per adjustment
Over a five-year period, a $1,500 commercial grinder with annual burr replacements and cleaning supplies costs about $2,200-2,500 total. That's $450-500 per year for professional-grade grinding performance, which is a small fraction of most cafes' operating budgets.
FAQ
Where can I find commercial coffee grinders for sale?
Restaurant supply stores, used equipment dealers, online marketplaces like eBay and Facebook Marketplace, and specialty coffee forums. Authorized dealers like Prima Coffee and Clive Coffee sell new units with full warranties. For used grinders, local cafe closings and equipment liquidation sales offer the best prices.
How much does a commercial coffee grinder cost?
New commercial grinders range from $800 for entry-level 64mm models to $5,500+ for flagship 83mm grinders. Used units in good condition typically sell for 30-50% of retail price. A refurbished Mazzer Super Jolly (64mm) might cost $300-500, while a used Mahlkonig EK43 runs $2,000-3,000.
How long do commercial coffee grinder burrs last?
It depends on volume. For a cafe doing 200 drinks per day, 64mm burrs last 6-12 months, 75mm burrs last 12-18 months, and 83mm+ burrs can go 18-24 months. For lower-volume use, double those timelines. You'll notice burrs need replacing when grind times increase, consistency drops, or you see visible wear on the cutting edges.
Should I buy a new or used commercial coffee grinder?
For a first cafe, I'd recommend buying the grinder new and getting the full warranty. It's one of the most important pieces of equipment, and a warranty gives you peace of mind during the critical first year. For a second grinder, a backup, or a batch grinder, used is a smart way to save money. Just inspect the burrs and motor carefully before purchasing.
Making Your Decision
The right commercial coffee grinder matches your volume, brewing method, and budget. For most new specialty cafes, a 75mm flat burr grinder from Mahlkonig, Eureka, or Mazzer will cover your needs for years. Buy new for your primary espresso grinder and shop used for supplementary equipment. Inspect burrs and motors on any used purchase, and budget for annual burr replacements as part of your operating costs. The grinder is where coffee quality starts, so this is the one piece of equipment worth spending on.
