Abstract: A method and apparatus for wirelessly monitoring and/or controlling the processing operations of a mobile rock crushing plant.

Abstract: A seal for sealing around a drive shaft protruded through a hole or opening in a liquid containing box. The seal includes a seal housing secured to the box and having a center opening, and a flinger sleeve secured to the drive shaft and projected through the center opening of the seal housing. The sleeve includes an inner wrap-around flange that extends axially inward and radially outward of the center opening to repel liquid directed towards the box hole. A clamping ring provides radial location setting of the seal housing relative to the shaft and axial location setting of the sleeve relative to the seal housing while also providing clamping of the sleeve to the drive shaft.

Abstract: A rock crushing plant including rock crushers, screens and conveyors. The assembly is modularized whereby major components and associated support structures are organized into movable modules that are independently movable from site to site over public roadways. The modules are equipped with appropriate support wheels for traveling and stabilizing jacks for stabilization of the modules at a rock crushing site. Modifications are made to certain of the components to satisfy road height and width restrictions, e.g., folding conveyors. Each module is preferably equipped with its own power plant.
