A mobile crushing system is for crushing inputted objects and dropping the crushed objects directly into an ore path. The mobile crushing system includes a crusher vehicle on which a crushing device for crushing the objects is mounted and which includes carriers, and a feeder vehicle on which a transfer device for transferring the objects to the crushing device and which includes carriers. The crusher vehicle and the feeder vehicle travel independently and include a crusher-side connecting portion and a feeder-side connecting portion that are connected to each other. During crushing operation, the ore path is interposed between the crusher vehicle and the feeder vehicle in the front-rear direction.

Disclosed are polyvinyl chloride resinous compositions containing cellular fillers such as Silus Balloon and pearlite and molded products prepared by subjecting the compositions to heating at an increased pressure. The molded products may be combined with a core layer such as a non-woven fabric and a victria lawn, a foamed layer such as PVC paste resinous foam, a surface layer such as a non-foamed synthetic resin and molded into laminated sheet products. Those are made lighter and superior in soundproof and adiabatic effects, bending strength, dry touchness, water resistance, dimensional stability, cold resistance and the like so that structural materials such as floor coverings and the like are supplied more advantageously as compared with conventional ones.
