Abstract: The present disclosure provides a generally cylindrical bowl support for a cone crusher which includes a plurality of evenly, circumferentially spaced ears around the periphery of the support. The ears are designed to have clamping cylinders mounted thereto to provide protection from tramp iron and the like passing through the cone crusher. A plurality of thickened ribs are defined in the support, at least some of the thickened ribs extending downwardly from the ears to form abutting polygon configurations to spread and absorb forces from a crushing operation. Other ones of the ribs define at least one circumferentially-extending, continuous ring forming portions of the polygons.

Abstract: Embodiments disclosed herein include a stacker for stockpiling bulk material. The stacker may include a linear conveyor having a rear portion including a hopper, and front portion, the conveyor being designed to carry bulk material along an elevating path from a low position adjacent the rear portion to a higher position adjacent the front portion. At least one leg may be mounted to the frame below the hopper, the at least one leg may include a hydraulic jack for increasing and decreasing the effective length of the leg, thereby raising and lowering the rear portion of the conveyor to increase and decrease a degree of elevation of the path. The hopper may be pivotally mounted to the conveyor, with hydraulic cylinders mounted thereto in order to raise and lower an end of the hopper to alter a degree of inclination of the hopper. Means may also be provided for maintaining the hopper in a horizontal disposition regardless of the degree of elevation of the conveyor.

Abstract: A rock crusher is provided that has a crusher cavity defined between a first part and a second part. A plurality of hydraulic cylinders are mounted between the first and second part, the hydraulic cylinders including a relief system. The relief system is included for reducing oil pressure within the hydraulic cylinders in the event uncrushables enter the crusher cavity, the relief system including a relief valve that is designed to open when hydraulic pressure in hydraulic cylinder reaches a predetermined level. This reduces the pressure in the hydraulic cylinder as oil pressure is dumped from the hydraulic cylinder via various oil passages.

Abstract: A portable trommel has a chassis, including support wheels at one end thereof for movement of the trommel. A trommel is rotatably mounted on the chassis and has an input and an output end. A hopper and an input conveyor, for supplying material to be screened to the input end of the trommel, are mounted on the chassis adjacent the input end of the trommel. An output or fines conveyor, for collecting material passing through the trommel screen, is mounted on the chassis, below the trommel. A stockpiling conveyor is mounted on the chassis and has a lower end adapted to receive screened material from the fines conveyor and an upper end for discharging screened material to form a stockpile. The stockpiling conveyor can be in two parts, which can be folded into a retracted position for storage and transportation, and further can be mounted for rotation about a vertical axis to enable an arcuate storage pile to be formed.
