Heavy Duty Eriez Vibratory Feeders in Aggregate Operations

This case study focuses on the operational efficiency of Eriez Model 75B Vibratory Feeders at Edwards Sand & Gravel, a company engaged in aggregate and quarry handling operations. The feeders are utilized to move crushed sandstone from the quarry to a belt conveyor, demonstrating a feeding capacity of up to 350 tons per hour, which is 20 percent greater than previous models. The quarry, operational for about 25 years, produces 750,000 tons of aggregate annually and has significant reserves remaining. The feeders are noted for their low profile and space-saving design, which enhances employee safety and workflow. They operate effectively in harsh conditions due to their electro-permanent magnet drive design, eliminating the need for lubrication. The case study also highlights the long-standing relationship between the company and Eriez, emphasizing trust and reliability in equipment procurement. Overall, the study illustrates the importance of robust equipment in maintaining production efficiency in the aggregates industry.
