there are some regulations out there that deal with compost piles. along with odor smell. along with water regulations (being to close to wells, lakes, streams, etc..) possibly run off water being an issue from pile/s. there may be some sort of distance issue from your own home / other folks homes.
keeping correct temperatures , aerating pile (turning pile) i would think help speed up overall process of stuff breaking down.
getting into non-aerobic bacteria, bugs, etc... that dislike oxygen. = generally takes much longer to break stuff down. when speaking about waste treatment.
getting into aerobic waste treatment that deals with getting air mix'ed into the process = a shorter time for stuff to break down.
would suggest contacting local agricultural department for your area. they might recommend some things. work with them and you will more likely get much further along.
might suggest watching some youtube videos from other folks that have some sort of composite buisness or DIY compost for homes. and reading up on the material. most of it is all the same just different amounts "small home" vs large waste from livestock. and ways of doing certain things to make better use of tools / area at hand.
