The hammer mills are fed radially for dualrotational operation to achieve uniform wear and full utilization of screens and hammers. Models with tangential inlets are available for low density products. The hammer mills have a directly coupled motor mounted on a base frame. The front doors are bottomhinged and open on sliding rails.
In filling mill by grinding balls on 40 – 50% and nonsmooth liner, the outer layers slip is virtually absent, but the sliding of the inner layers one on another observed in various modes of operation mill. In a monolayer filling mill by grinding media, they rotate around their axis parallel to the drum axis of rotation.
FEECO Hammer Mills. The FEECO double rotor hammer mill is a super heavyduty mill adapted to do the toughest jobs with two sets of chain / bar links. Our hammer mills reduce dry and semimoist materials with a minimum amount of fines and caking or plastering within the crusher. They are ideal for granulated and pelletized materials.
other products may be called flaking mills or flakers. Roller mills used to grind in a feed mill are commonly referred to as a roller mill or roller mill grinder. Double pair (two pair high) roller mills may be utilized in feed milling operations when two distinctly different grains are processed through one mill
Optimal hammer design and placement will provide maximum contact with the feed ingredient. Hammer mills in which the rotor speed is approximately 1,800 rpm, should be using hammers which are around 25cm (~ 10 inches) long, 6.35cm (~2.5 inches) wide, and 6.4mm (0.25 inches) thick.
