For brewing high-quality coffee drinks, blade grinders don’t grind reliably. They chop the coffee beans with a blade resembling a propeller. How long you let the grinder run using the timer built into the machine will decide how fine the grind is. The coffee gets finer as it grinds for a longer period of time, check this out
The disadvantages of a blade grinder are that the coffee builds up a static charge, which will make it stick to just about everything, and that the grind can vary from chunks to powder. This makes the coffee quite messy. We do not suggest blade grinders due to these factors.
In the meantime, the burr grinder is the component of the grinder that uniformly grinds the coffee beans, which is necessary for making outstanding espresso or coffee. Conical or flat plate burr grinders are the two types available.
Two cone-shaped burrs with ridges are used in conical burr grinders to crush or grind coffee. Flat Plate Burr Grinders have two parallel, identical rings, one of which is serrated on the opposite side. One burr on each burr grinder is stationary, and the other is rotated by the motor. The beans are crushed into a consistent size after being drawn between the two burrs. Both varieties of grinders have a reputation for dependability and excellence. With either one, you simply can’t go wrong.
If both grinders are compared, the residential and commercial grinders can use either type of burr. They offer a consistent grind appropriate for any high-end or inexpensive espresso equipment. Conical burrs are frequently used on gear reduction grinders with very low speeds. Flat plate burrs can be utilized with a wide range of grinders, including low-cost, high-speed grinders and low-speed, direct-drive grinders of professional quality.
