The cycle time of polymer compositions subjected to a rotomolding process is improved (i.e., reduced), while the processing window is simultaneously enlarged through the use of a polymer-stabilizing amount of a processing stabilizer system having at least one chroman-based compound according to Formula V: 

Processing additives and uses of same in rotational molding

Stabilizer compositions having a chroman-based compound according to Formula (V): and their use in processes for stabilizing organic materials subject to degradation and/or discoloration due to the effects from light, oxygen and heat, and in processes for producing articles from organic materials blended therewith, are provided herein.

Stabilizer compositions containing substituted chroman compounds and methods of use

A mobile crushing station for receiving and comminuting excavated material from earth moving vehicles provides at least one moveable skip connected to a chassis or frame for receiving material from vehicles, such as rear unloading vehicles like dump trucks. The skips are configured to move to dump material fed into the skips into a feed hopper. The feed hopper is positioned to guide material onto a feed conveyor, such as an inclined apron conveyor. The feed conveyor is configured to transport material to a feed orifice of a crushing device, such as a sizer, a crusher, or a crushing circuit. The crushing device is configured to crush material fed into the crushing device. The crushing device also has a discharge orifice that is positioned above a portion of a discharge conveyor. The mobile crushing station is moveable so it may be repositioned closer to an excavation site as excavation activities progress.

Mobile crushing station

A conveyor apparatus includes a first conveyor apparatus and a second conveyor apparatus. The first conveyor apparatus is positionable adjacent to a feed conveying device. The first conveyor apparatus is configured to pivot about a position adjacent to the feed conveyor device or move laterally adjacent to the feed conveyor. The second conveyor apparatus is configured to move such that the second conveyor apparatus maintains a position substantially parallel to the first conveyor apparatus when the first conveyor apparatus moves or pivots. In some embodiments, the second conveyor apparatus may also be configured to move along a path so that the second conveyor apparatus is extendable beyond an end of the first conveyor apparatus. The path may be a linear path and may be substantially parallel to the length of the first conveyor apparatus such as a path that extends in a direction that is a few degrees off of being perfectly parallel.
