A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while material is fed into a feed hopper.

Pros of Two Roller Grain Mills. Two roller mills are substantially cheaper than three roller mills and provide adequate results for the average homebrewer. The benefits of a three roller grain mill can largely be achieved by running the grain through a two roller mill twice. This makes the price savings worthwhile for homebrewers on a budget.

Winner: Smooth face hammer. Durability: Milled face hammers tend to be more durable than smooth face hammers because the textured surface helps to protect the head from impact. When the head of a hammer hits a hard surface, such as a nail or piece of wood, the shock is absorbed by the milling. This reduces the risk of cracking or chipping.
