Lead Slag Screw Conveyor is a waste slag conveying equipment designed for lead smelting and recycling industries. Addressing the characteristics of lead slag—high temperature, high hardness, and corrosive media—it employs a customized structure and materials to achieve safe and stable continuous transfer. This conveyor supports horizontal, inclined, and vertical conveying, with a conveying capacity of 10-50 m³/h and a conveying length of 3-30 meters. It can flexibly connect to process nodes such as lead smelting slag outlets, slag bins, and crushing equipment. Its compact structure and small footprint make it particularly suitable for complex layouts in smelting workshops. The blades and trough can be replaced individually after wear, reducing later maintenance costs. Suitable angles, power outputs, and multiple feed and discharge points can be customized according to your production site.
The material selection for a Lead Slag Screw Conveyor requires comprehensive consideration of the physical properties of lead slag and the process environment. Our factory can provide three types of materials: alloy steel, stainless steel, and wear-resistant composite steel plates, to meet the needs of different customers.
Alloy steel: A balanced choice between high strength and wear resistance, its comprehensive mechanical properties are significantly improved through heat treatment. It is suitable for conveying dry, uniformly sized lead slag, and for medium- and low-temperature environments, avoiding softening during high-temperature annealing.
Stainless steel: Represented by 304 and 316L, it has outstanding resistance to pitting and crevice corrosion, and its smooth surface effectively reduces material adhesion. Its core applications include conveying lead slag containing acidic or alkaline components, and in food, pharmaceutical, and other fields with stringent hygiene requirements.
Wear-resistant composite steel plate: With a high-hardness alloy layer welded to the surface, its wear resistance is 5-10 times that of ordinary steel plates. It is suitable for conveying large-particle, sharp-edged lead slag, and for high-wear, high-impact environments.
With its strong sealing performance, wear and corrosion resistance, large and continuous conveying capacity, the Lead Slag Screw Conveyor can adapt to complex working conditions such as high temperatures and strong corrosion, effectively reducing material loss and environmental pollution.
High conveying efficiency: The screw conveyor can achieve continuous and uniform conveying, with a conveying capacity of tens to hundreds of tons per hour, meeting the needs of large-scale lead slag processing.
Angled conveying: The horizontal conveying angle can reach 20°, and the vertical conveying height does not exceed 6 meters, suitable for production lines with complex layouts.
Multi-point feeding/discharging: By opening multiple feeding and discharging ports on the shell, flexible distribution and collection of lead slag can be achieved.
Flexible conveying: Using a flexible screw conveyor, the conveying task can be completed in three-dimensional space, reducing the equipment footprint.
Sealed and environmentally friendly: The fully enclosed shell design effectively prevents lead slag dust from overflowing, and with the dust removal system, it can meet environmental protection requirements.
The Lead Slag Screw Conveyor mainly consists of a drive unit, screw assembly, trough assembly, sealing system, and support components. The drive unit employs an explosion-proof motor and a hardened gear reducer, providing high output torque suitable for high-load lead slag conveying. The screw assembly includes a main shaft and wear-resistant blades, with the blades designed for full-surface operation to improve conveying efficiency. The trough has a U-shaped structure with wear-resistant material lining the inner wall to reduce lead slag wear. The sealing system includes a dust cover and end cap seals to prevent dust leakage. Support components include bearing seats and brackets to ensure stable equipment operation. All structures work together, designed to meet the high-temperature and wear-resistant requirements of lead slag, achieving safe and continuous transfer.
The lead slag screw conveyor uses a motor to drive the screw shaft to rotate. The continuous propulsion of the screw blades transports materials such as lead slag from the inlet to the outlet.
Feeding Stage: Lead slag enters the conveyor housing through the inlet and accumulates at the bottom of the housing under gravity.
Propulsion Stage: The motor drives the screw shaft to rotate, generating friction between the blades and the material, causing the material to move in the direction of blade rotation. Simultaneously, the material adheres tightly to the inner wall of the shell under centrifugal force, forming a stable propulsion layer.
Discharge Stage: Under the continuous propulsion of the spiral blades, the material reaches the discharge port and is naturally discharged under gravity, completing the conveying process.

Can screw conveyors be used with corrosive lead slag?
Yes. Targeted corrosion-resistant configurations are necessary, such as using 316L stainless steel or duplex steel for the tank and blades, with a PTFE lining on the inner wall; anti-corrosion treatment for welds; and corrosion-resistant seals. This resists the corrosive effects of acids and alkalis in lead slag, achieving sealed and stable conveying.
For large-particle, highly abrasive lead slag, how should a Lead Slag Screw Conveyor be selected?
Emphasis should be placed on wear resistance enhancement. The spiral blades should use wear-resistant composite steel plates with a high-hardness alloy outer layer to resist impact and wear; partial ceramic lining should be laid at the bottom of the tank to enhance the durability of easily worn areas. A heavy-duty reducer should also be included to prevent material jamming.
What is the horizontal conveying length of a Lead Slag Screw Conveyor?
The horizontal conveying length can reach 30 meters, meeting the material transfer needs of most workshops and sites. If a longer conveying distance is required in actual working conditions, multiple units can be connected in series. Through reasonable planning of equipment layout and connection methods, continuous and stable conveying can be achieved.
How is the high-temperature resistance of the lead slag screw conveyor?
The lead slag screw conveyor boasts excellent high-temperature resistance, with standard configurations capable of withstanding temperatures up to 600℃. The core components utilize a low-carbon steel base with an alloy weld overlay, maintaining structural strength even at high temperatures. If the conveying temperature exceeds 600℃, a double-layer water-cooling jacket can be added to prevent material annealing through circulating water cooling.
