Higher productivity is achieved through the use of special high alloy, low wear knives. Their unique construction provides less downtime for replacement or resharpening. When maintenance is required, knives can be individually replaced or resharpened outside the cutting chamber. This permits sharpening of the full edge and prevents contaminants from entering the chamber.

Maintenance ease applies to more than just the knives. The hinged cabinet can be opened or removed without tools for total access. The cutting chamber is accessible from a hinged hopper or front and rear chamber access doors which may be removed for total cleanout or knife adjustment from above the machine. The specially designed discharge blower swings away from the machine without the need to disconnect wires or piping.

The cutting chamber, a heavy one-piece weldment, has all internal surfaces ground smooth for easiest cleaning during color or material changovers. The assembly is mounted on I-beams on the smaller size, and on the large sizes, a 3″ thick steel bed plate; which results in maximum rigidity, even under stress, for the frame and drive mechanism..

The rotor is solid steel with three rows of knives. These knives are specially ground on a shear angle for point contact cutting. A multiplicity of 15″ long knives is used, rather than one long knife. This arrangement permits the removal of one knife from each row for stagger-cutting action sometimes used on thinner materials.

Foremost’s new 30″ X 30″ large barrel grinder is intended for pit mounting and features an over 1000 lb flywheel, pneumatically operated feed control with direct vertical drop, and numerous servicing convenience features.

The rotor in the 3030 granulator, a massive open weldment, has six staggered fly knives. Outboard isolated pillow block bearings with 6″ journals, a 32″ 1067 lb steel flywheeel and a seperate drive sheave using five belts complete the drive system. The staggered rotor knife design results in more positive, uniform< feeding, smoother operation and a better distribution of impact stresses.

You can use Foremost’s standard HD-5B Granulator for a second stage; or replace it with any model you choose. Dual stage granulators use two separate cutting chambers. The first has a solid cylindrical rotor embedded with 18 disc-shaped cutters which shave off small sections or pieces of the solid lumps loaded in the hopper. The greater the weight of purgings on this rotor, the higher its output.

The DSC-18 upper stage uses unique disc-type cutters. Their concave “cutting circle” has been optimized through extensive engineering analysis to achieve maximum output at the lowest power requirement. Since just one quarter of each disc is used for cutting at any time, a new keen surface can be easily revolved into place simply by loosening a single hold-down bolt on each disc when it dulls. In this way, four fresh surfaces are available on each cutter before the disc must be removed for resharpening. And since the knives rest in machined seats in the upper chamber rotor, no gap settings are ever required. Knife access is obtained by pivoting the hopper to one side.
