Portable 42" Gyratory Crusher ? Introduction

For the past 50 years, the primary crushing of stone at the Dolase Bros. Co. Richards Spur Quarry. 13 miles north of Lawton, Oklahoma, has been accomplished by a Traylor 42-inch gyratory crusher. The production capacity of the primary system, consisting of a feeder, grizzly, and the gyratory crusher, was approximately 2100 tons per hour. Shot-down scone was hauled from the working face about one mile to the feeder by a fleet of Caterpillar Model 773's and WABCO 60- and 65-ton trucks. In order to maintain production, nine to ten trucks and four Caterpillar Model 992 front-end loaders were required to be operational at all times.
