Twin-shaft Screw Conveyor

1.Product Overview

The twin-shaft screw conveyor is a high-efficiency continuous conveying equipment equipped with two parallel counter-rotating screw shafts.Different from the single-shaft type,its double-spiral structure achieves forced material pushing,mixing,stirring and dense conveying at the same time.It is specially designed for wet,sticky,bulky,easy-to-block and mixed bulk materials,and widely applied in environmental protection,chemical industry,building materials,mining,food and waste treatment fields.

2.Working Principle

Two screw shafts rotate synchronously in opposite directions.The intermeshing spiral flights limit material floating and backflow,and continuously squeeze,push and convey materials forward.The double-shaft interleaved structure can break up agglomerated materials during transportation,realizing integrated functions of conveying,homogenizing and feeding.

3.Core Structural Features

Double parallel drive system,stable operation and strong driving force;

Interlocking screw blades,anti-blocking design,reducing material winding and accumulation;

Sealed U-type or fully enclosed tank body,dust-proof and leak-proof,meeting environmental protection emission standards;

Wear-resistant lining plate and high-strength alloy shaft body,strong compression and corrosion resistance;

Customizable feeding and discharging ports,supporting horizontal and small-angle inclined installation.

4.Key Advantages

Strong material adaptability:Suitable for wet sludge,clay,biomass,fertilizer,coal slime,sticky powder and mixed materials that single-shaft conveyors cannot handle;

Anti-blocking&self-cleaning:Mutual scraping of double shafts effectively prevents material adhesion and clogging;

High conveying density:Forced feeding structure with large volumetric conveying capacity and stable discharging;

Multi-function integration:Complete conveying,mixing and homogenizing in one process to simplify production layout;

Environmental&energy-saving:Fully sealed structure,no dust overflow,low noise and low energy consumption.

5.Main Application

Environmental protection industry:Municipal sludge,industrial sludge,garbage residue conveying and transportation;

Chemical industry:Chemical powder,wet granule,viscous raw material and compound fertilizer;

Building materials&mining:Clay,coal slime,mineral powder,wet sand and limestone powder;

Agricultural&biomass:Crop straw,manure,feed raw materials and organic fertilizer materials.

6.Technical Characteristics

Conveying capacity:Large volume,higher efficiency than single-shaft conveyor of the same specification;

Equipment material:Carbon steel as standard,stainless steel or wear-resistant alloy for special anti-corrosion and wear-resistant working conditions;

Driving mode:Chain drive,gear reducer drive,stable and suitable for heavy-load operation;

Sealing performance:Fully sealed design,adaptable to harsh working conditions with high humidity and high dust.
