MOTRIDAL - Screw Conveyors
From Material Handling Systems
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.
Product Overview
Motridal’s range of production includes every type of screw conveyor, from the most common tubular or channel trough screw conveyors, to screw feeders, dosers, mixers, where the process and transport requirements are combined.
The design and selection of materials are adapted each time to the properties of the product to be conveyed (abrasiveness, bulk density, size, moisture, chemical properties, etc.).
Trough ends are dust-tight with bearings suitable both for radial and axial loads; longer screw conveyors are equipped with intermediate hanger bearings (made by Motridal) properly spaced, in order to minimise shaft deflection.
Thanks to its Augers Division, which produce forged and continuous flighting, Motridal can manufacture, upon request, machines for special purposes, with shape, dimension and materials, not included in standard production.
Features
- Drive unit composed by a parallel axis motor-gear that is directly mounted on the drive shaft, with torque arm and rubber shock absorbers. As an alternative, drive units can be equipped with chain drive or belt drives.
- Intermediate Hangers are used to minimise shaft deflection, avoiding contact between the flights and casing.Intermediate hanger bearings may be lubricated or self-lubricated and the two shafts can be connected by means of pin and bushings or by removable plates for easy shaft replacement. Intermediate hangers are also available in a “Heavy Duty Series” (for ØS > 400 mm).For special applications, the shafts of screw conveyors up to 12 m can be oversized in order to avoid the installation of intermediate hanger bearings.
- Inlet/outlet easily removable to allow a perfect cleaning of the screw casing when conveying sticky materials.
- Cleaning Hatches easily removable to allow a perfect cleaning of the screw casing when conveying sticky materials.
- Head supports can be of divisible pillow blocks mounted on an external frame or Motridal’s design, cast iron flanged supports. Sealing between shaft and head plates can be made by means of stuffing box with adjustable packing gland, or by means of blow-in air, for special applications.
- Flighting can be continuous or forged sectional flighting, with constant or variable thickness. The materials more commonly used are: Carbon Steel (S235JR, S275JR, S355JR), Stainless Steel (AISI 304, AISI 316 and 400- class), and wear resistant steel (T1, Hardox 400, Creusabro 321, 4800 and others).
