The conventional mechanised wet grinder was inspired from the traditional manual wet grinder. The primary component , the stone and the mortar are made from a specific kind of stone, found in abundance in the quarries surrounding Coimbatore.The mechanised wet grinder of the conventional type consists of an electric motor that is mounted on a wooden or plastic base. The base also houses the grinding stone and the mortar. A chain links the mortar to the base unit and rotates in a faster and more efficient manner, as compared to the manual rotating process.
