manufacture screw conveyors for transportation of bulk solids. Standard
materials of construction used are stainless steel (AISI-304 &
AISI-316) polished to a suitable finish. However, other materials
with appropriate surface treatment can also be employed, depending
upon the application. Conveyor flights will be selected from amongst
standard ones such as sectional, helicoid, ribbon or cut type, depending
upon the application & product characteristics.
a standard practice, geared motors & variable speed drives are
used to achieve desired operating torque & good control over
the delivery rate. Also, PTFE bush supports, ball bearings, &
mechanical seals (or stuffing boxes) are used on one or both ends
to prevent leakage through the shaft openings. In cases where the
conveyor length is large, hangers with adjustable bearings are provided
at appropriate distances.
conveyors are suitable for transportation of a wide variety of bulk
solids, ranging from light, finely divided non-abrasive solids to
abrasive, pasty & lumpy ones.
