Burr grinders are more consistent than blade grinders. This is important when it comes to coffee extraction. Thus we can see there are generally two types - conical burr coffee grinders and flat burr coffee grinders on the market. Most home grinders use conical burrs since they are cost effective.
We manufacture coffee grinder burrs in 95%, 99% and 99.5% alumina. Alumina represents the most commonly utilized ceramic material in industry. Due to its extremely superior abrasion and chemical resistance, alumina has been widely used in makeing coffee grinder burrs.
