What does a screw conveyor actually do?

A screw conveyor moves bulk powders, grains, granules, and semi-solid materials from one point to another through a rotating helical screw (the auger) inside a sealed closed trough. The screw turns, the material moves along its length, and because the trough is closed the material stays contained - no dust escaping into the plant, no contamination from outside, no spillage. It is the right tool whenever you need to move bulk material that is not in a package or bag - flour, sugar, cement, grain, fertilizer, plastic pellets, recycled granulate - and you cannot or should not use an open belt or roller conveyor for it.

What materials does the screw conveyor handle, and what is the cooling jacket for?

The screw conveyor handles bulk powders (flour, sugar, cement, fly ash), grains (wheat, corn, rice, animal feed), granules (plastic pellets, fertilizer), and semi-solid materials. Catalog applications specifically cover animal feed, grains, sugar, and sand. The optional cooling jacket is for materials that need temperature control during handling - sugar that clumps or caramelizes when warm, flour that loses quality if exposed to friction heat, fertilizers that degrade above certain temperatures, and chemical powders with reaction-sensitive temperature limits. The jacket wraps around the trough exterior and circulates cooling water or chilled fluid, drawing heat out of the material as the screw moves it through. Standard screw conveyors do not need this; specific products and continuous high-volume operations do.

Can the screw conveyor work both horizontally and inclined?

Yes - this is one of the defining features. Horizontal operation handles the highest capacity at the lowest energy cost. Inclined operation lets the conveyor lift material up to feed silos, hoppers, mixers, or upper-floor equipment without needing a separate vertical lifter. The trade-off is that capacity drops as the incline angle increases - typical industrial design keeps inclined screw conveyors under 30 degrees for efficient operation, though steeper angles are possible with reduced throughput and specialized screw geometry. SANAM sizes the screw diameter, pitch, and motor based on your specific incline angle and target throughput so the conveyor performs at the duty point you actually need.

Mild steel or stainless steel — which construction should I choose?

Material choice depends on what the screw conveyor will handle. Mild steel is the cost-effective standard for industrial powders and abrasive materials - cement, sand, fly ash, construction materials, recycled aggregates - where food-grade hygiene is not required and the lower material cost matters. Stainless steel SS 304 is the standard for food-grade applications: flour, sugar, animal feed, grain, food powders, and pharmaceutical bulk materials. Stainless steel SS 316 is for aggressive chemistries, fertilizers, and applications where SS 304 would corrode. The trough, screw flights, and end bearings can all be specified in different materials based on the application. SANAM recommends the right material during the engineering consultation based on your specific bulk product.

Does the screw conveyor integrate with silos, hoppers, and upstream equipment?

Yes - integration with silos, hoppers, mixers, packers, and other bulk handling equipment is standard scope. The inlet can be configured as a hopper-feed (for gravity-fed delivery from above), a flange-feed (for direct connection to a silo discharge), or a side-feed (for connecting to mixers or process equipment). The outlet can be configured as a gravity discharge, a controlled discharge gate, or a direct flange to downstream equipment. SANAM engineers the inlet and outlet geometry to match your existing or planned upstream and downstream equipment, with PLC integration available for plants running automated bulk handling lines.

Material Handling Conveyor

Screw
Conveyor

The conveyor that moves bulk material without spilling a gram — a rotating helical screw turning inside a sealed closed trough that handles powders, grains, granules, and semi-solid materials without dust escape, contamination, or spillage. Runs horizontally or inclined at an angle, with an optional cooling jacket for materials that need temperature control during handling — sugar, flour, fertilizers, chemical powders. Built in mild steel for industrial powders and cement, or stainless steel SS 304/316 for food-grade and pharmaceutical handling.

Key Features

What Makes a SANAM
Screw Conveyor
Different

Six things that set a SANAM-built screw conveyor apart from a generic imported solution — every one of them a decision we make at the engineering desk before fabrication begins.

Sealed Closed Trough — Dust-Tight Containment

The defining feature — the helical screw turns inside a fully sealed closed trough. Bulk material stays contained: no dust escaping, no contamination falling in, no spillage. The right choice when the material is fine, hazardous, valuable, hygienic, or messy.

Built for Real Bulk Materials

The screw conveyor handles bulk materials that defeat most other conveyors: powders that aerate, grains needing gentle handling, granules flowing like liquid, and sticky semi-solids. Catalog covers feed, grains, sugar, sand; we also handle flour, fertilizers, plastic pellets, cement, fly ash.

Horizontal or Inclined — Same Cell

The catalog confirms it — screw conveyors run horizontally or inclined. Horizontal gives the highest capacity at the lowest energy. Inclined lifts material up into silos, hoppers, or upper-floor equipment without a separate vertical lifter. Industrial design keeps incline angles under 30 degrees.

Optional Cooling Jacket — Catalog-Distinctive

When cooling is needed during material handling, we add a jacket that wraps the trough exterior and circulates cooling water or chilled fluid. Critical for sugar that clumps when warm, flour that loses quality from friction heat, and fertilizers that degrade above certain temperatures.

Mild Steel or Stainless Steel — Built to Your Product

Material choice depends on what the conveyor handles. Mild steel for industrial powders and abrasive materials — cement, sand, fly ash — where food hygiene is not needed. SS 304 is standard for food-grade: flour, sugar, animal feed, grain. SS 316 is for aggressive chemistries — acids, alkalis, fertilizer corrosives.

Custom-Engineered to Your Product — Not a Catalog Box

Every screw conveyor SANAM builds is sized to the specific product — density, particle size, abrasion class, moisture, temperature, flow behavior. Screw diameter, pitch, rotation speed, motor power, trough length, inlet and outlet geometry, and material of construction all specified during engineering.

Industries Served

Where the Screw Conveyor Earns Its Place

Six industries where the sealed-trough screw conveyor removes the dust, contamination, and spillage problems that defeat open conveyors when handling bulk powders, grains, and granules.
