Choosing the Right Conveyor System: A Guide for Process Engineers & Plant Managers

When it comes to material handling in the food, chemical, mineral, and biopharma industries, selecting the right conveyor system is critical. Process Engineers, Plant Managers, Project Managers, and Procurement Managers must weigh multiple factors—including material properties, energy efficiency, and maintenance costs—to ensure seamless operations.

This guide explores the differences between pneumatic and mechanical conveyors, their industry-specific applications, and how our expertise in engineering design, process plant installation, and equipment fabrication can help optimize your operations.

Pneumatic Conveyors: Efficient, Clean, and Flexible

What Is Pneumatic Conveying?

Pneumatic conveying systems use air pressure or vacuum to transport bulk materials through enclosed pipelines. This method is ideal for handling fine powders, granules, and small particulates over long distances.

Advantages of Pneumatic Conveyors

• Flexible Routing: Easily integrates into existing plant layouts with minimal modifications.

• Dust-Free Operation: Enclosed systems prevent contamination, ensuring compliance with strict industry standards.

• Low Maintenance: With fewer moving parts, downtime is significantly reduced.

Disadvantages of Pneumatic Conveyors

• High Energy Consumption: Blowers and compressors require substantial power.

• Not Ideal for Heavy Materials: Best suited for light, free-flowing substances rather than dense or abrasive solids.

Industry Applications

• Food & Beverage: Sugar, flour, cocoa, and coffee beans.

• Chemical: Plastic pellets, powders, and hazardous substances.

• Biopharma: APIs, excipients, and other sensitive powders.

• Minerals: Fine-grained materials like cement or talc.

Key Components

• Blowers or Compressors: Generate the airflow required for transport.

• Rotary Valves & Feeders: Regulate material entry into the system.

• Pipelines & Elbows: Designed for wear resistance and minimal clogging.

• Separators & Filters: Ensure efficient material discharge and air filtration.

Mechanical Conveyors: Reliable, Cost-Effective, and Ideal for Heavy Loads

What Is Mechanical Conveying?

Mechanical conveying systems use physical components such as belts, screws, or chains to move materials. These systems are typically employed for handling larger, heavier, or more abrasive bulk materials.

Advantages of Mechanical Conveyors

• Energy-Efficient: Requires less power than pneumatic systems.

• Ideal for Heavy Loads: Suitable for high-density materials and large volumes.

• Consistent Flow: Provides steady transport, reducing batch inconsistencies.

Disadvantages of Mechanical Conveyors

• Higher Maintenance: Moving parts are subject to wear and tear.

• Larger Footprint: Requires more space compared to pneumatic conveyors.

Types of Mechanical Conveyors

• Belt Conveyors: Best for long-distance material transport but require open space.

• Screw Conveyors: Ideal for enclosed, controlled material movement.

• Bucket Elevators: Efficient for vertical transport but need regular maintenance.

Industry Applications

• Food Processing: Transporting grains, dairy powders, and bulk ingredients.

• Chemical Plants: Moving abrasive or corrosive substances.

• Mineral Processing: Handling large rocks, ores, and mining materials.

Pneumatic vs Mechanical Conveyors: Which One Should You Choose?

Choosing between pneumatic and mechanical conveying depends on several factors:

For facilities requiring hygienic and flexible transport, pneumatic systems are the preferred choice. However, if handling large volumes of abrasive materials, mechanical conveyors offer greater efficiency and durability.
