Glass Conveying Systems
The glass industry in India is a vital part of the manufacturing sector, producing container glass, flat glass, and specialty glass for diverse applications. Driven by growth in construction, automotive, and packaging sectors, it combines traditional craftsmanship with modern technology, contributing significantly to exports and domestic industrial development.
Pneumatic conveying in the glass industry plays a critical role in modern glass industry material handling, enabling efficient, dust-free transport of bulk solids like silica sand, soda ash, and limestone. It ensures a consistent feed to batch houses, improves plant hygiene, reduces material loss, and minimises manual handling. Doing so enhances productivity, safety, and reliability in raw material handling across glass manufacturing processes.
Bulk Materials in the Glass Industry
The following materials are used in precise proportions to produce various types of glass for industrial and consumer applications.
- Silica Sand: Primary component, provides silica (SiO₂) for glass formation
- Soda Ash (Sodium Carbonate): Lowers the melting point of silica
- Limestone (Calcium Carbonate): Adds durability and chemical stability
- Feldspar: Improves hardness and resistance
- Dolomite: Provides magnesium and calcium, enhancing strength
- Borax: Lower melting temperature & enhances thermal & chemical durability
- Alumina: Increases chemical resistance
Improve glass manufacturing efficiency with our precise and dust-free pneumatic conveying solutions.
Solutions offered by Macawber
- 1. Dense-phase pneumatic conveying system
Dense phase conveying for glass manufacturing is ideal for abrasive bulk materials like silica sand, soda ash, and dolomite. It uses low-velocity, high-pressure air to move materials in slug flow, minimising wear on pipelines and preserving material integrity. This solution ensures reliable, long-distance transport with reduced maintenance and operational downtime. We offer dense phase solutions with capacities ranging from 1 TPH to 25 TPH over distances of up to 100 metres, subject to application. Learn more about our complete range of Dense Phase Pneumatic Conveying Systems.
- 2. Lean-phase pneumatic conveying system
Dilute phase systems transport lighter, less abrasive materials, such as feldspar and alumina, using high-velocity air, making them well-suited for applications typically handled by lean phase pneumatic conveying systems. In this system, material is suspended in the airflow, allowing continuous, low-pressure conveying. It’s suited for applications where material degradation is not a concern, offering flexible routing and easy integration.
- 3. Batch Feeding Systems
Batch feeding systems deliver precise quantities of raw materials into the batch house or furnace. Integrated with weighing and metering controls, they ensure accurate formulation of glass batches. These systems improve process consistency, reduce waste, and support automation in glass production, leading to higher quality and operational efficiency.
- 4. De-dusting system
Effective dust collection is critical when handling fine, powdery glass raw materials. Integrated filtration systems capture airborne particles during conveying, improving plant hygiene and worker safety. They help manufacturers comply with environmental regulations, reduce dust-related wear on equipment, and maintain the cleanliness of sensitive production areas.
- 5. Automation
Macawber’s automated pneumatic conveying systems enhance operational efficiency, accuracy, and safety, making them integral to advanced conveying systems in glass manufacturing. By integrating sensors, controls, and real-time monitoring, we optimise material flow, reduce human intervention, and ensure precise delivery, all while minimising downtime and improving overall reliability.

Frequently Asked Questions
Pneumatic conveying uses pressurised air to transport bulk glass raw materials like silica sand, soda ash, and limestone through enclosed pipelines. It enables dust-free, automated material handling from storage to batch houses, ensuring consistent feed rates and improved plant hygiene.
Common materials include silica sand (primary component), soda ash, limestone, feldspar, dolomite, borax, and alumina. These vary in abrasiveness and flow characteristics, requiring different conveying approaches: dense phase for abrasive materials and lean phase for lighter components.
Glass plants use dense phase systems for abrasive materials like silica sand (low velocity, high pressure) and lean phase systems for lighter materials like feldspar (high velocity suspension). Batch feeding systems with weighing controls ensure precise formulations.
It provides automated material handling, eliminates manual labour, reduces material loss, maintains dust-free environments, and ensures precise batch formulations. This results in improved safety, consistent product quality, reduced waste, and enhanced overall productivity.
