The grinding mechanism is nylon and the copper body is thin with a plastic insert that holds the salt. This may be necessary to help minimize salt corrosion, but it is definitely not solid metal construction like the pepper mill.
This Atlas 8 inch salt mill is hand made in Greece using the same methods used for the past 300 years with durable all metal bodies and a nylon grinding mechanism. It is fitted with a nylon liner to protect the mill from corrosive salt. The Atlas mill is a unique piece of European tradition that is functionally the best in the world
110 Copper Sheet amp Plate, is widely known for its architectural applications whereas the familiar green patina appearance is acheived when exposed to the sheets and plates have excellent hot or cold workability and is ductile when heated. Copper sheets plates are also noted for their high electrical and thermal conductivity, and good corrosion resistance.

Grinding is a subset of cutting, as grinding is a true metalcutting process. Grinding is very common in mineral processing plants and the cement industry. Grinding is used to finish workpieces that must show high surface quality and high accuracy of shape and dimension. It has some roughing applications in which grinding removes high volumes

Enfield Rolling Mills was in Millmarsh Lane, Brimsdown, Enfield, Middlesex on a 40acre site set up in the early 1920s with a copper refinery Enfield Copper Refinery, rod mill, wire mill, brass cake foundry, hot and cold rolling mills, 39Encon39 continuous casting plant for bearing alloys, billet casting foundry and forge for high conductivity
Rates measured in a laboratory system compared favorably with those measured in the field. Cast steel was found to have corrosion rates in a copper mill and laboratory test cell of 22 and 21 mpy, respectively. Corrosion was found to account for less than 5 pct of the total grinding media wear in the operations studied.

Copper metals are inherently corrosionresistant, but thin tarnish films andor patinas can form over time. Clear organic coatings can retard formation of such films and thus preserve the metals natural colors by acting as physical andor chemical barriers to atmospheric chemicals.
This mechanochemical process can leach 9799 copper directly on site, from concentrates as low as 5 copper in less than six hours. This makes it feasible for you to produce cathode copper from concentrate directly at the site rather than to sell the concentrate to a smelter. The ROL process can even leach copper from arsenicladden concentrates.
