Screw conveyor

horizontalverticalfor the mining industry

Screw conveyors are often used inside plants because they are completely enclosed, thus material transfer is weather-proof and dust-free. Thanks to the small number of installed components, these machines require minimum maintenance. Motridal’s range of production varies from the most common tubular or channel trough screw conveyors, to screw feeders, dozers, and mixers, where process and transport requirements are combined. Trough ends are dust-tight with bearings suitable both for radial and axial loads; longer screw conveyors are equipped with intermediate hanger bearings, in order to minimise shaft deflection. Thanks to its Augers Division, that produces forged and continuous flighting, Motridal can manufacture, upon request, machines for special purposes, with shape, dimension and materials, not included in standard production. Motridal supplies tubular and troughed screw conveyors suitable for all industrial sectors. Depending on the application and specific requirements, the built materials are appropriately selected (carbon steel, stainless steel, anti-wear steel, alloys resistant to high and low temperatures). Hot materials, like ashes, are often required to be cooled down before discharging or conveying to downstream process. Motridal, if the process conditions allow it, is able to design and provide water cooled screw conveyors to reach the desired outlet material temperature.
