How long was the development process of the machine for crushing stone

1 answer:

6 0

Answer:

Well based on the fact that the very first patented rock crushing machine was made in the year 1830, and the first successful, Eli Whitney Blake's, was in 1858, I'd say the development process was around 30 years.
