What is hammermill used for?Hammermills have traditionally been used to produce the finer grinds commonly used for pelleting and for many mash (meal or non-pelleted) feed applications as well. The hammermill is a relatively simple machine and requires a fairly low degree of s in regards to both the operation and maintenance.What is a roller mill?A mill used to crack grain or other types of friable materials may be called a cracking mill. Mills used to flake grains or 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.What is the mean particle size?Although technically it is not correct, the mean particle size (in microns or µ) is commonly referred to as the “average” or the “micron size”. Another common calculation performed in the size analysis procedure is to determine the “log- normal standard deviation”.What is descriptive terms?Descriptive terms such as coarse, medium and fine are simply not adequate. What is “fine” in one mill may well be “coarse” in another. Describing the process or equipment is also subject to wide differences in terms of finished particle size(s) produced.Should rotor be supported at each end?As noted earlier, the rotor should be supported at each end, preferably with standard bearings and bearing housings. This will provide a degree of rigidity not available with an “overhung” rotor design and reduce any problems with rotor shaft “wind up”, even if the mill operates with an out of balance rotor.What is step grind?Step grinding in the simplest terms, is size reduction accomplished in steps or stages, usually incorporating two grinding machines (hammermills, roller mills, pulverizers, or some combination thereof). The primary objective of step grinding is to reduce the cost to produce a ton of fine ground finished product.

What does a roller mill do?Roller Mill Maintenance. Roller mills are used around the feed mill to perform a variety of tasks. Applications include crumbling pellets, cracking corn, dry rolling and steam flaking grain, and grinding corn, wheat, or milo for mash and pelleted feeds.What happens when rolls are not in parallel?When the rolls are not in tram or parallel, there is a tendency for the material being processed to "drift” in the nip of the rolls towards the open end(s). This excess material may over time actually begin to “pile up” in the nip of the rolls and cause accelerated wear.Best roll corrugation lifeAs noted, the best roll corrugation life will be realized with easy to process materials like corn, soybean meal, and pellets made from similar products. As products become tougher or contain more abrasive impurities, roll life will be reduced.Can you switch top and bottom rolls?After rolls have been recorrugated two or three times, the top pair will be smaller in diameter than the bottom pair in a two pair high machine. To maintain the best capacity and mill performance, it is a good idea to switch the top and bottom rolls after two, three, or four recorrugations.What is two pair high roller mill used for?In two and three pair high machines it is necessary to “balance” the work being done between the pairs of rolls to avoid uneven roll wear. When properly managed, a two pair high roller mill used for grinding corn or cracking soybeans will wear the top and bottom pairs of rolls at approximately the same rate.What causes a roller mill to shift?If the roller mill is operated with the rolls out of tram or out of parallel, significant thrust loads may be exerted on the rolls and bearings. In machines with straight bore bearings, the forces may be enough to cause the rolls to shift sideways in the machine, even contacting the mill frame.
