Eriez® has announced the expansion of its extensive B-series line of heavy-duty electromagnetic vibratory feeders with four all-new B-HC high-capacity models.
Boasting nearly 70-100% greater capacity than previous models, these feeders offer the widest capacity range in the industry, capable of delivering controlled amounts from just a few pounds to 1,089 t of bulk material per hour, the company claims.
The B-HC line of feeders incorporates an innovative electromagnetic drive that features an exceptionally strong rare earth permanent magnetic armature assembly. This system applies power in both the forward and reverse directions of the feeder tray, ensuring precise linearity and control compared to traditional attract-release systems. The coil-and-magnet assembly is encased in epoxy, protecting it from dust and moisture, eliminating coil movement and significantly extending the feeder’s lifespan.
Equipped with a compact and energy-efficient AC control system, Eriez B-HC feeders provide precise, variable-speed feed rate control with accelerometer feedback. The design eliminates sliding and rotating parts, enhancing profitability and productivity by reducing power consumption and maintenance requirements.
B-HC feeders are ideal for head-load applications below a hopper, efficiently metering bulk materials to belt conveyors, screens, crushers and elevators. Standard and custom-engineered trays can be supplied with features such as dust covers, screens and grizzlies. Abrasion-resistant steel or UHMW liners are optional.
These feeders support both base and suspended mounting options, with the flexibility to choose between undermount or overhead drive configurations. Rob Yandrick, Eriez Global Product Manager-Vibratory, says that the 65B-HC feeder is already demonstrating its superiority among early adopters, including Washington Mills, a leading producer of abrasive grains. Yandrick explains that Washington Mills previously needed their feeder to run at full capacity to meet material feed requirements. In contrast, the 65B-HC can deliver the same feed quantity while maintaining significant feed capacity in reserve.
The full range of high-capacity electromagnetic feeders is being officially unveiled at MINExpo INTERNATIONAL 2024, in Las Vegas, this week.
