About the manual coffee girnder, which is better: ceramic or stainless steel burr?

Advantages

Temperature: high speed rotation heating up slowly, the temperature is relatively stable

Deformation: Ceramic is not easily deformed after heating up, and the shape is relatively normal

Cost-effectiveness: in general, the grinder with stainless steel core is cheaper than the grinder with ceramic core.

Manual coffee grinder with ceramic burr temperature is relatively low, will not be the second heating of the coffee powder; the price is also relatively cheap, suitable for beginners to use.

Noise: compared to ceramic core coffee bean grinder, the noise is relatively larger

Hardness: the inner core is ceramic, a little less hard than stainless steel blades, with a certain degree of flexibility.

Fragile: coffee bean grinder with a very high breakage rate. Especially when the coffee beans have foreign objects (stones, nails, etc.)

Grindability: uneven grinding

The ceramic core coffee bean grinder is only suitable for home use, not for commercial use.

Advantages

Noise: relatively low noise, relatively more quiet

Hardness: the burr is stainless steel, relatively hard, not easy to wear.

Grinding degree: stainless steel burr has a knife edge, coffee bean grinding coarser and finer relatively more uniform

Coffee bean grinder with stainless steel burr is sharper and quieter to use, but relatively expensive and more suitable for daimler and commercial use

Temperature: high speed grinding coffee beans, heating up relatively quickly, the second heating of the coffee powder

Deformation: coffee bean grinder with stainless steel burr heats up faster, which can easily lead to core deformation

Cost-effectiveness: in general, grinders with stainless steel burr are more expensive than grinders with ceramic burr.
