The 10 Worst Blade Grinder Fails Of All Time Could Have Been Prevented
Blade Grinder - Why You Shouldn't Use One
A blade grinder employs an e-type propeller (think blenders) to chop coffee beans. They are cheaper than burr mills and easy to clean, however they don't create a uniform ground and can cause bitterness or excessive extraction in your coffee.
To get the best coffee experience, you must have uniform distribution of particles. This is only possible using a burr mill. This is the reason why coffee snobs loathe burr grinders.
Inconsistent Grinds
If you've been using a blade grinder for some time there's a good chance that your grinding results have changed. This is because the grinding device has likely become dull and worn out. As the grinder gets older it will produce different sized pieces of beans. This results in ground with different degrees of coarseness. It's a challenge for your coffee brewer to get the same, balanced taste due to the different sizes of the particles.
Blade grinders use the same propeller-like blade to break beans. It basically chops the beans into smaller and smaller pieces, which are then dropped through a screen into the catcher. While this method is effective, it's not ideal for making the most perfect grind for your beverage. A better option is the burr grinder. A burr grinder is a much larger machine that has a powerful motor and two grinding burrs. The burrs can be set at a certain distance apart which determines the coarseness of the coffee that is ground.
If the burrs get too close, they smash rather than cut beans. This results in a finer, less coarse ground. They are also more brittle, which can negatively impact your coffee's taste. On the other side, if the burrs are too spread out, they will create large chunks of coarsely-ground coffee. It is important to select a grinder that has a setting that matches the coarseness you want.
A sharp blade, adjusted properly, will produce a consistent and fine grind for your coffee. If you find that your grind is becoming more uneven, it's probably best to replace the blade or burrs. It is also advisable to change the grind setting if you haven't before in order to help you achieve an even grind.
It's also worth mentioning that if your grinder creates clumped up grounds this could be an indication of worn or damaged blades. The clumping happens due to tiny particles bonded to one another and larger pieces of ground, creating larger granules that aren't able to dissolve in water. As your burrs become more and more dull, this will occur more often.
Uneven Extraction
If you're brewing drip, French press, or pour-over, the size of your grounds plays an important role in flavor extraction. Uneven sizes of the grounds cause uneven extraction, resulting in an imbalanced cup of coffee.
The beans are cut into pieces and shred indiscriminately as they move through a blade mill, which results in an uneven distribution of grind particle size. A blade grinder can create a mix of large pieces, dust-sized particles, and everything else. Different grind sizes produce at different rates, leading to an inconsistent and often bitter cup of coffee.
The lack of uniformity also results in problems with the tamping process and filtration. With a burr mill you can get a uniform particle size, allowing better tamping and filtration, which prevents over-extraction. With a blade grinder it is more difficult to attain an even grind. You might be tamping from side to side or using the Stockfleth method (which requires some time to master).
Another problem with blade grinders is their speed and the generation of heat. This could cause the ground to become burned and create a bitter taste. Burr grinders create less heat and are cooler, preserving the flavor of beans.
A final downside of grinding with a blade is that it's very easy to over-grind your beans. The grinder will generate a lot heat and your beans will eventually become over-extracted. This can result in a bitter drink. To avoid this, put the grinder off before turning it back on.
Blade grinders are a simple, inexpensive way to grind coffee at home. However they're not the ideal option for those who are serious about their brewing. You'll want to stick with whole beans and use burr grinders for the best results.

A burr mill, on the other hand creates a uniform distribution of particle sizes that can be replicated over a number of brews.
Blade grinders offer a variety of advantages, including their low cost and speedy operation. However, they have some disadvantages for instance, the fact that they produce heat when used, produce inconsistent grind sizes and are not able to control the final particle size. There are ways to increase the efficiency with this kind of grinder despite its inherent limitations.
When using a burr mill, the user can easily alter their desired ground size by adjusting the gap between the discs. This lets them to extract the flavor they desire every time from their favourite coffee beans. However, creating a quality beverage using a grinder takes a lot of trial and trial and.
An angle grinder is a potent tool that should be used only by trained personnel. It can cause grinding burn when it is used improperly. This can cause localized changes to the metallographic surface of the workpiece. This could lead to cracks that, if unchecked, can eventually result in macropitting and tooth fracture.
Grinding burn is a serious issue that can be caused by a variety of factors including excessive grinding pressure, inadequate cooling, or improper operator training. If you intend to use an angle grinder, be sure you wear the correct PPE such as gloves and a face shield, safety glasses, steel toe boots and long sleeves.

These sparks can be as hot as 3,600 degF, and can be able to burn through the materials like paint or metal.
Brew that is disappointing
