    Roller chains are made up of a series of cylindrical rollers that are connected by links. The distance from one roller-pin center to the next is considered the "pitch" of the chain. There are standard sizes of roller chains available starting with a petite 25 chain up to a massive 240 chain.

  • Mill (grinding)Wikipedia

    A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g. via a hand crank) working animal (e.g. horse mill) wind or water (). The initial outlay for a roller as well as the whole idler frame can be quite substantial. However you should consider the entire service life of this important componentry in line with your operating system outlay.. Each time a roller or idler system needs to be serviced or replaced this cost can potentially be substantial as the conveyor system needs to be completely isolated and shut down.
