| SCREW CONVEYOR :- i) Functions : A versatile conveying equipment which can be used for almost all bulk solids from fines to lumps of 3" size. Conveyor capacities can vary from few Kgs. Minimum to 500 M3 / HR and diameters ranging from 150 mm to 1200 mmand speeds from 175 RPM to 10 RPM. It is meant to convey materials from One point to another horizontally and can do so without any dusting and spillage at very reasonable power expense. This equipment can also be used for inclined conveying for which capacity duration to be considered while sizing. This will depend on inclination sought and material characteristics. ii) Construction :- Helical flights made from prime quality steel, cold pressed in die to retain its strength, welded on strong central pipe, encased in 'U' or 'Circular' trough rolled out of steel plates. Screw pipe ends are fitted with carefully selected shafts, machined and supported by high quality bearings. Shaft exists are properly sealed by glands, bearings are housed in outboat type housing so as to ensure avoidance of dust ingress. Top of 'U' trough is sealed by top cover. Fixing will depend on application / specific locations to ensure easy maintenance. Equipments are generally provided with rugged saddle type short supports. Any other supporting arrangements can be tailored to suit clients specific requirements. Additional feature is provision of reverse flights at both the ends to ensure smooth flow of material to discharge spout / opposite to shaft exists only and do not gather at the ends. Hanger bearings of various proven designs are available and made to suit applications wherever the screw length exceeds. the standard available length of pipe or 2.5 / 3 mtr. Interval. This solely depends on diameter of screw and lengths required. |
