This can also be added to existing designs. When it comes to magnetic drum separators and scrap drums, one will find that the magnetic power of new magnetic drum separators may be incorporated into the old model. With vibratory feeders, newer designed prod- ucts now come equipped with energy- saving components that should be explored before someone rebuilds or buys new. These should be asked for when a rebuild order placed. Today's metal detectors come with software and even smart phone technol- ogy that one may wish to consider. By talking to the rebuild facility, one can investigate whether they need to go new or can upgrade their current unit. What's the Timetable? When is the product needed? At Eriez, it typically takes one to four weeks to rebuild most products. They may be able to expedite delivery at a premium price. The delivery lead time of new ver- sus rebuild will need to compared. When they have stopped production or face safety issues that compromise their working environment, they will need to find the best answer in terms of a firm delivery date. Evaluate the Warranty and the Vendor's Reputation Mining operations entail numerous pieces of equipment working together in a seamless operation to bring the fin- ished product to market. Metal detec- tors, magnetic separators, vibratory feeders, screeners and conveyors all play an integral role in many functions. Mining companies use this equipment independently or in a comprehensive flow system to help increase product purity, preserve downstream equipment and improve productivity. Since process equipment represents a significant capital investment, plant operators should perform routine inspections to detect any malfunction- ing or underperforming equipment. This procedure helps spot trouble areas, minimizes downtime, and prevents potential harm to plant personnel and downstream equipment. There are several ways to determine which rebuild facility to trust with an upgrade project. Companies can ask for references from past and present cus- tomers or ask their peers who have used the facility. They can also visit the rebuild facility and see first hand the setup and how equipment is repaired and upgraded. Warranty is also important. Be sure to understand the extent of the warran- ty before committing whether to buying new or rebuilding. Eric Taylor is manager of Eriez Manu- facturing Co.'s 5-Star Service Center.
