    Abstract: Methods for making elastomer compounds are described. The compounds include reclaimed vulcanized elastomer materials such as micronized rubber powders (MRP). The elastomeric compositions exhibit lower tensile strength variability. As described herein, shorter mixing times can be used to achieve the same minimum tensile strength as composition containing no reclaimed material. The elastomeric compositions may include various proportions of reclaimed vulcanized elastomer materials. A rubber compound is also described which comprises reclaimed material and which has a minimum tensile strength equal to or higher than a predetermined minimum tensile strength associated with a compound containing no reclaimed material. The rubber compound is manufactured with a reduced mixing time compared to that of the compound with no MRP.

    Abstract: An impact mill including a base portion on which is disposed a rotor rotatably mounted in a bearing housing, the rotor having an upwardly aligned cylindrical surface portion coaxial with the rotational axis. The impact mill is provided with a mill casing within which is located a conical track assembly which surrounds the rotor to form a conical grinding path. The mill casing is provided with a downwardly aligned cylindrical collar which may be axially adjusted to set a grinding gap between the rotor and the mill casing. The rotor is provided with a plurality of impact knives complementary with a plurality of impact knives disposed on the inside top surface of the mill casing. The conical track assembly can be a series of assembled conical sections or one unit with varied number of serrations in either a vertical or sloped configuration. This flexibility allows for greater compatibility with the feedstock being milled.

    Abstract: Elastomer compositions comprising uncured elastomer and reclaimed elastomer are described. In one embodiment, the compositions comprise reclaimed elastomer material (micronized rubber powder) of broad particle size distribution, which is less expensive than traditional reclaimed elastomer material with narrow particle size distribution. Further, compositions comprising reclaimed elastomer materials with broad particle size distribution perform comparably to those comprising reclaimed elastomer materials with narrow particle size distribution. In other embodiments, the compositions comprise both vulcanized and devulcanized elastomer materials. Advantageously, by using a combination of vulcanized and devulcanized material, it is possible to incorporate a greater percentage by weight of reclaimed material in to an elastomer composition, thus providing additional cost savings while maintaining high levels of mechanical properties. Further, the use of the reclaimed material reduces landfill waste resulting in a more environmentally friendly product.
