Building Aggregates Plants to Suit Customers’ Needs

When building a new aggregates plant, getting exactly what is needed to provide customers with the precise spec materials they want — and do it as productively and efficiently as needed to be profitable in an increasingly competitive and demanding market can be challenging.

And will the new system be capable of handling day-in, day-out grueling operations and/or increased production requirements in the future without being overkill in the present — and thus being overly expensive to purchase and operate in the present?

Grasan of Mansfield, Ohio, engineers and manufactures all or integral parts of total systems, using whatever types, brands and combinations of equipment are best suited, according to the manufacturer.

Experienced engineers will research available equipment, processes, recent developments and innovations related to the customer’s project. It also can do material analysis, product specification tests and system capacity checks. Process flow charts are created to show how the system will work, including all components and their production capacities. Costs are itemized and options spelled out to show costs versus benefits.

Grasan has extensive experience in custom-engineering precision structures for all or part of virtually any quarry application. Field assembly normally is accomplished without the use of a cutting torch and welder. CAD-CAM is used for the design/build and detailing of each system and plates and wear liners are cut with a computer-controlled plasma burner to assure perfect fit-up. Beams and structural shapes are cut with a modern, high-speed saw for accuracy and squareness and extra heavy-duty structural members and oversized conveyors and drives provide longer wear life and can generally handle production increases.

Shop fabrication is monitored for consistent weld quality and most structures are shop-assembled for proper fit. Strategic placement of wear liners and rock boxes minimizes maintenance and wear costs. Maintenance is further aided by large access doors, roll-away chute designs and convenient access platforms.

Grasan field technicians are available for assistance during assembly and startup. Operation and maintenance manuals are written for each system and Grasan can provide training for production and service personnel.
