Abstract: An illustrative example enclosure includes a support frame having longitudinal beams and lateral channel members that define an outward facing flow passage. A first roof panel and a second roof panel respectively include lateral edges aligned with the channel members. The lateral edge of the first roof panel is situated adjacent the lateral edge of the second roof panel. An interface between the lateral edge of the first roof panel and the lateral edge of the second roof panel is situated above or within the flow passage of one of the channel members. At least one seal engages the first roof panel and the second roof panel. The seal is received in the flow passage of the channel member in sealing engagement with the channel member.

Abstract: A grinder roll assembly (500) is provided herein. The grinder roll assembly (500) includes a grinder roll (505), a shaft (510) in a through bore of the grinder roll, a first tapered sleeve (615A), and a second tapered sleeve (615B). The first tapered sleeve (615A) fits between the shaft (510) and the grinder roll (505) in one direction, and the second tapered sleeve (615B) fits between the shaft (510) and the grinder roll (505) in an opposite direction to form at least one friction lock that mounts the grinder roll (505) to the shaft (510).
