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. While each application has some unique aspects, maintenance and operation of the equipment is remarkably similar.

Ease of maintenance, lower operating cost. The grinding roller can be taken out from the machine through the hydraulic device, a large space for maintenance. Both the two sides of the roller shell can be used for a longer working life. The mill can run without raw material on the grinding table, which erases the difficulty in starting.

Hammer mill is the most widely used grinding mill and among the oldest. Hammer mills consist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact. The materials to be milled are struck by these rectangular pieces of hardened steel (ganged hammer ...

Principle of operation The grinding material is comminuted in the Loesche roller grinding mill between the rotating horizontal grinding track and the stationary grinding rollers. Grinding is effected primarily by compression. A certain amount of shear force increases the quantity of fine particles in the grinding material.

roller mill operator can control the particle size by widen-ing or narrowing the roll gap. For most roller mills, the roll gap is automatically adjusted through a PLC that's pro-grammed to change the gap to match the specs for a new product or batch. This allows roll gap adjustments to be made in just seconds while the mill is operating ...

Fluid energy mills. The general principle of operation in a fluid energy mill is that the material to be ground is fed into a grinding chamber in a high speed, high pressure and, often, high temperature jet of air (or other gas). The particles collide violently and this causes comminution to take place.
