Martin Shaftless Screw Conveyors — The Problem SolverMartin Shaftless Screw Conveyors are theideal solution for hard-to-transport materialsranging from irregularly shaped dry solids suchas scrap wood and metals, to semi-liquid andsticky materials including pulp, compost, foodprocessingrefuse, hospital waste, and wastewaterproducts.Martin Shaftless Conveyors’ simple, pipelessdesign employs fewer parts than conventionalshafted-screw conveyors, reducing lifetimemaintenance costs. It enables higher troughloading and lower RPMs, maximizing the volumeof materials conveyed. Martin‘s Shaftless Screweliminates jamming and buildup typical inshafted-screw conveyors for greater uptime,higher efficiency, and lower maintenance. Iteliminates hanger bearings and end bearingsto reduce maintenance and increase efficiency– enabling direct transfer to another conveyor.Martin Shaftless Screw Conveyors andcomponents are manufactured and stocked atour branches strategically located near majorindustrial markets across North America. Thisensures rapid shipping on new installations andnext-day delivery on stock replacement parts.Several test units, as well as video footageof actual applications, are available fordemonstration of the unique capabilities ofthe shaftless screw.
