Abstract: A palletizer or depalletizer of containers with a product carrier and product support having four pickup or deposit positions providing improved operational speeds and container placement precision. The ends of two air cylinders are slidably secured to at least one crank arm of a pivot shaft disposed in the carrier, actuation of the cylinders causing rotation of the shaft and the product support.

Abstract: A gyratory mantle liner assembly for use in a gyratory cone crushing machine; each assembly includes a retaining ring formed from high density steel having a conical lip on the edge surface thereof, a conical shape upper liner having arcuate teeth and a bevelled lower-end surface on the arcuate teeth formed from mild steel, a plurality of lower liner segments having an upper arcuate tooth surface with a bevelled edge and a seat, and a retaining nut for tightening and holding in position the upper and lower liner segments. The lower liner segments defining the crushing surface are made from heat treated alloy material and are arranged in a ring fashion on the bell skirt without the need for adhesives.
