Conveyors are no strangers to dust: It's generated by rubbing corrugated boxes during packaging, the conveying of pet food or bakery confectionary, and in the processing of other granular products that go airborne and then settle. The trouble is that the very T-slots that simplify attachment of accessories to conveyors in these applications also collect and trap dust.

To address this issue, Dorner Mfg. Corp., Hartland, Wis., now offers DustPruf 2300 and 5300 Series conveyors that feature solid sides with indented guide grooves called SmartSlots — thin, continuous racing stripes that mark the sections of conveyor frame engineered to be thinnest and easily tapped — for the mounting of guides and automation accessories with self-tapping screws and a cordless drill, even on curved sections.

The new conveyors are suitable for dusty or dirty environments requiring occasional wipedown or spot cleaning, or in medical and pharmaceutical production, where dust is unacceptable. An FDA-approved, low-friction bedplate coating also reduces friction with the conveyor belt by 20% — so load capacity is increased that much for a given motor.
