The Major Electronic Low RPM Commercial Burr Grinder from Mazzer is the epitome of what a commercial grinder should be. It handles a huge amount of coffee with a four-pound bean hopper and industrial-grade 83mm burr grinder plates. But it's not all power and muscle, the Major also has a tasteful and attractive steel housing, a well-designed exterior that is meant to take center stage in your coffee shop or kitchen. We think it's safe to say that there's nothing minor about this Major, especially when it comes to the exceedingly fine control and quality the Major allows.

Features and Functionality

  • Large Capacity - The sturdy clear plastic bean hopper with finger guard holds holds a whopping 4 pounds of beans.
  • Consistent Grind - The 83mm stable stainless steel burr grinders are flat and remove for easy cleaning. Designed to operate at a super low RPM (rotations per minute) so that minimal heat builds up and is transferred to your beans.
  • Stepless Adjustment - Features a stepless micro-metrical grind adjustment for total control over the precise grind of your beans.
  • Cooling System - The internal fan prevents the motor from overheating and guarantees consistent and uniform coffee grinds.
  • Dosing Control - Programmable to grind by time at the push of a button for fresh espresso directly into your portafilter.
  • Huge Blades - The giant burr blades ensure that it can handle the large quantities of beans it holds.
  • Large Hopper - Super large hopper holds four pounds of beans.
  • Nobody Puts Major in a Corner - With large capacity and output comes a huge footprint. This is not a machine that can be tucked under a counter.

What type of grind retention does this machine have? If I grind about 20grams, how much should I expect to be withheld in the chamber?
Yarden F on Apr 21, 2014
Best Answer: Yarden,

I've only just started using the grinder, but it appears that all of the grind falls out of the chamber. If you lift the cover with the digital readout off, you see all the way through to the portafilter. There may be some grind left in the machine itself but my guess is that if there is it is nominal. Hope this helps

can I get 220v?
A shopper on Mar 13, 2015
Best Answer: No, all of the grinders that we carry are only available in 110v. If you are needing 220v, you would need to purchase internationally. All grinders in the US run on 110v, and anything higher is not necessary for the machine.
