Abstract: A system relating to ceramic/rubberized lined steel pipes adapted to carry crushed rock and other highly abrasive materials.

Abstract: An inflatable liner with vibratory function related to lining mining hoppers and other such devices. The inflatable liner has an exterior expandable layer and ceramic wear layer beneath that assists maintaining a long-use-life of the inflatable liner. Use of the air-control device to rapidly inflate and deflate exterior expandable layer vibrates in the exterior expandable layer and assist removing unwanted material/debris from the exterior lining of exterior expandable layer to further maintain a long-life use of the inflatable liner and lower maintenance of the machinery/hopper.

Abstract: A screen for a vibrating material sorting apparatus of the type used to sort material in mining operations and the like has a plurality of rows and columns of trapezoidal apertures formed through it. The apertures are oriented so that the narrowest end first encounters material moving down the screen. The apertures are further tapered in cross section, and flare outwardly from the top surface of the screen to the bottom surface. In addition, each of the apertures slopes at an angle which is selected to be the same as the degree of incline of the screen when it is mounted in a vibrating material sorting apparatus.

Abstract: A vibrating screen apparatus for effecting screening of materials includes a frame with first and second vibrating screen deck units mounted one above the other in it. To provide maximum flexibility of operation, the vibrating deck units are pivoted at the material feed end on the frame. Hydraulic cylinders are attached between the free ends of the first and second vibrating screen deck units and the frame for independently varying the angle or slope of each of the deck units, relative to the frame, for adjusting the dwell time of material passing over the deck units. A flexible corrugated rubber curtain extends between the upper deck unit and the lower deck unit to ensure that material which passes through the upper deck unit is guided onto the surface of the lower deck unit. In addition, each of the vibrating screen deck units has an independent vibrator mechanism on it; so that the vibration rate and magnitude may be independently adjusted for each of the deck units in the system.
