Jeffrey Rader - Model Mini-Mill -Hammermills

Unmatched Versatility
You can use these small-to-medium-sized hammermills in a wide variety of applications. The type of material you are reducing determines the rotor configuration, and the product size you desire determines the screen bar arrangement.

For pulverizing friable materials such as limestone, Jeffrey Rader hammermills come with rectangular swing hammers. For shredding materials such as waste paper, fiberglass mats, or rubber–or when the application requires the machine to run at slow speed–choose rigid hammers.

EZ Access® Technology
The hammermills have been designed with Jeffrey Rader’s exclusive EZ Access technology, which allows safe, fast, and easy access to the hammers, rotor and liners. Now maintenance operators can safely and quickly perform routine maintenance with more safety and ease.
 
Screen Grates
Jeffrey Rader fabricated screen grates, racks and bars and perforated plate is designed to provide the greatest amount of free open area, allowing the machine to obtain the highest capacity while accurately sizing the material to the specified size. Our screen grates are made of abrasion resistant materials, but can be supplied with other materials depending on the application and sizing requirements.

Heavy-Duty Rotor Design
Our disc-type rotor is assembled on a high-strength, alloy-steel shaft and is mounted in self-aligning spherical roller bearings (Models 30ABE & 34AB) or ball bearings (JR & mini) in rugged steel housings. Rotor discs allow maximum flexibility of hammer arrangements. Jeffrey Rader rotors can setup with three, four, or six rows of hammers for premium efficiency when shredding to a smaller product size.

Hammer Designs
Our hammers are manufactured from our Ultralloy® material to provide the ultimate in performance, long life and low operating costs. The hammers are hard throughout, yet still have the ductility and toughness to withstand high-impact conditions. Where the application requires we have both harder and softer materials to provide the optimal performance and life in the hammers while keeping operating costs to a minimum. In addition to our current material offerings, we are constantly looking at new alloys to improve overall equipment performance.

Our hammers also are available in a variety of shapes from a standard bar hammer to a six-point rigid hammer. The hammer design is based on the application and when combined with the appropriate material will ensure the machine is operating at its maximum efficiency.

Steel Housing
Rolled-steel, structurally reinforced housings ensure long-lasting durability. When properly maintained, the hammermill’s fully-lined interior prevents the housing from wearing on the inside. Doors on the upper housing provide access to the metal trap and the interior of the machine.
