Screw Conveyor

A screw conveyor transfers cement, fly ash, mineral powder, and other powder materials from silos to weighing systems, mixers, or production lines. It is used in concrete batching plants, dry mortar plants, cement silos, and powder handling systems where sealed conveying and controlled feeding are required.

Model Advantages

Screw Conveyor Advantages for Powder Feeding Layout Planning

QIC Machinery screw conveyors are selected according to powder type, bulk density, required capacity, conveying distance, installation angle, silo outlet height, downstream equipment position, motor power, flange interface, shaft support, and maintenance access. The focus is to help your project match the conveyor with the actual powder feeding route.

Diameter and Capacity Matching for Powder Feeding

LSY219, LSY273, and LSY325 models can be compared by pipe diameter, reference capacity, motor power, conveying distance, and installation angle. The selected model should match powder consumption, silo outlet flow, weighing hopper demand, and production line layout.

Inlet Feeding and Screw Pitch Review

Powder pressure at the silo outlet, butterfly valve opening, inlet hopper shape, screw pitch, and motor load should be reviewed together. This helps your project prepare a more suitable feeding condition before the conveyor starts daily operation.

Hanger Bearing and Shaft Support Planning

Longer tubular conveyors may require intermediate hanger bearings and shaft support. Bearing type, shaft alignment, powder abrasiveness, sealing condition, and inspection access should be considered during configuration and maintenance planning.

Flange, Angle, and Retrofit Interface Matching

Retrofit projects often need to connect existing silo outlets, weighing hoppers, mixers, or plant frames. Inlet flange size, outlet height, installation angle, gasket method, ball joint range, and site measurement should be checked before production.

Core Systems

Screw Conveyor Core Systems

A screw conveyor normally includes tube body, screw blade, drive motor, reducer, inlet flange, outlet flange, hanger bearing, sealing structure, and connection supports.

The tubular casing carries cement, fly ash, lime, filler, or mineral powder along the conveying route. Tube diameter, wall thickness, support position, coating, inlet opening, outlet position, and inspection access should match the selected LSY model and site layout.

Layout & Installation

Conveyor Angle and Connection Confirmation

QIC Machinery helps you check silo height, conveying distance, installation angle, inlet and outlet position, support frame, power supply, and connection with the weighing system or mixer.

Powder Type and Bulk Density Review

Cement, fly ash, lime, filler, mineral powder, and other dry materials have different flowability and bulk density. Powder condition, moisture, abrasiveness, and storage pressure should be checked before selecting conveyor diameter and motor power.

Conveying Length and Installation Angle Check

Conveying capacity changes with installation angle and transfer distance. Your project should confirm total length, lift height, angle range, silo outlet position, downstream inlet height, and available support points before choosing LSY219, LSY273, or LSY325.

Silo Outlet and Inlet Flange Measurement

The inlet flange should match the silo outlet, butterfly valve, gasket position, bolt pattern, and material drop direction. For retrofit projects, site photos and existing flange dimensions should be reviewed before production.

How do I choose between LSY219, LSY273, and LSY325 screw conveyors?Click to expandClick to close

Choose according to required capacity, powder type, bulk density, conveying length, installation angle, silo outlet height, downstream equipment position, and motor power. LSY219 is suitable for compact feeding layouts, LSY273 fits common batching plant powder transfer, and LSY325 can be reviewed for higher-capacity powder feeding routes.

What powders can a screw conveyor transfer?Click to expandClick to close

LSY screw conveyors can be configured for cement, fly ash, lime, filler, mineral powder, calcium powder, and other dry powder materials. Powder flowability, moisture, abrasiveness, and bulk density should be checked before configuration.

What affects screw conveyor capacity?Click to expandClick to close

Capacity depends on screw diameter, powder bulk density, conveying length, installation angle, motor power, inlet feeding condition, outlet height, material moisture, and operating method.

How does installation angle affect conveying output?Click to expandClick to close

As the installation angle increases, powder transfer usually becomes more demanding because the screw must lift material against gravity. The final model should be reviewed according to angle, conveying distance, powder type, required capacity, and motor configuration.

What conveying length should I choose?Click to expandClick to close

Conveying length should be based on the distance between the silo outlet and downstream equipment inlet, available support points, installation angle, maintenance access, and site layout. Longer routes may require shaft support and additional layout review.

How should the screw conveyor match a cement silo?Click to expandClick to close

The conveyor should match the silo outlet diameter, butterfly valve, inlet flange, gasket method, discharge height, installation angle, powder type, and downstream weighing or mixing equipment. Site measurements should be reviewed before production.

How should the screw conveyor match a concrete batching plant?Click to expandClick to close

For a batching plant, the screw conveyor should connect the cement silo or fly ash silo to the powder weighing system. Plant capacity, powder weighing speed, mixer position, silo height, and control interface should be reviewed together.

Can a screw conveyor be used in dry mortar plants?Click to expandClick to close

Yes. Screw conveyors can transfer cement, filler, lime, calcium powder, and other dry materials between silos, weighing bins, mixers, and packing sections in dry mortar plants. Powder type and formula requirements should be reviewed before configuration.

What should be checked for retrofit projects?Click to expandClick to close

Retrofit projects should provide existing silo outlet size, butterfly valve position, inlet and outlet flange dimensions, bolt pattern, installation angle, conveying length, downstream inlet height, available support points, voltage, and site photos.

What wear parts should be prepared?Click to expandClick to close

Common spare parts include hanger bearings, bushings, seals, shaft connection parts, flange gaskets, fasteners, reducer parts, and selected electrical components. The final list should match conveyor length, powder abrasiveness, and working frequency.
