Two is better than one

摘要

There are a variety of reasons to increase the hourly production rate of a rock crushing-screening plant. One reason is to maintain or increase the daily production output while eliminating the overtime labor costs. Further, extensive long workdays are fatiguing for the work crew, which results in work inefficiency. Justifying a second shift may not be warranted, so the challenge is to increase the production rate efficiently and cost-effectively to eliminate the overtime; in turn, this reduces the labor costs per ton of aggregates produced. Meeting this challenge successfully might require a significant capital investment in terms of new equipment needed for the crushing-screening plant. But choosing the most cost-effective equipment can be a challenge. Leo Journagan Construction Co. Inc. successfully met the challenge recently by increasing the production rate of one of the crushing-screening plants it operates. All overtime labor costs have been eliminated as a result.
