The given diagram provides information about the process by which

cement

and concrete are produced. Overall, it requires 6 steps and a number of tools to manufacture

cement

from crushing limestone and clay to packing into bags. Meanwhile, there are 4 materials and a mixer in order to make concrete. The

first

step to produce

cement

is to put limestone and clay into a crusher by which these two materials are crushed into powder. Once the crushed powder has been put into a mixer, it

then

goes through a rotating

before being packed into bags. Regarding the
