The paint and pigment industry produces essential materials for protective, decorative, and functional coatings. It involves the formulation of paints, inks, dyes, and coatings by blending pigments, binders, solvents, and additives. This industry serves diverse sectors like construction, automotive, and consumer goods, with a strong focus on quality, consistency, and innovation.
Pneumatic conveying for paints and pigments is vital for the efficient, dust-free transfer of powders and granules. Pneumatic conveying in the paints and pigments industry ensures precise material handling, minimises contamination, and protects particle integrity. Used in batching, mixing, and packaging, pneumatic systems support consistent quality and automation in modern paint and pigment production processes.

Macawber’s Solutions for Smart Paints and Pigments Handling
At Macawber, we specialise in engineering customised dense-phase pneumatic conveying systems for challenging powders, making us a trusted partner for the paints and pigments industry. Our pneumatic conveyors for paints and pigments are built around the principles of efficiency, accuracy, and dust-free operation, with a focus on long-term system reliability and ease of integration with existing process control architectures.
- Jumbo bag & small bag unloading system
Our systems begin with ergonomically designed jumbo bags and small bag unloading stations. These units are equipped with dust-tight enclosures, integrated dust extraction systems, and mechanical agitators or bag massagers to ensure complete discharge of materials such as pigments, extenders, and additives. For smaller operations, manual or semi-automatic bag splitters are also available, allowing for safe and efficient material input with minimal operator exposure to dust.
- Drum handling & tilting
Drum handling and tilting in the paint and pigment industry involve safely lifting, transporting, and pouring heavy drums containing powders. Specialised equipment like drum lifters and tilters ensure precise control, minimises spillage, and reduces worker strain, enhancing efficiency and safety during material transfer and batch processing operations.
- Dense phase pneumatic conveying system
Our dense-phase pneumatic conveying systems are at the core of material transport. These systems use low-velocity, high-pressure airflow to gently move materials through pipelines, minimising segregation, preserving product quality, and greatly reducing wear and air consumption. Each system is built with our patented Dome Valve®, ensuring reliable sealing and unobstructed material flow, making them ideal for both batch and continuous processing lines.
- Lean phase pneumatic conveying system
In the paint and pigment industry, lean phase pneumatic conveying systems transport cohesive, moist, or sticky powders, coarse granules, and flakes efficiently. Using high-velocity air, they ensure smooth flow, prevent clogging, and maintain material consistency—critical for quality formulations and continuous production in pigment dispersion and paint manufacturing processes.
- Storage silos with flow promoting devices
To support intermediate storage, we supply robust storage silos constructed from mild or stainless steel. These silos are fitted with flow-promoting devices such as fluidising pads, air blasters, vibration systems, bin bottom vibrators, bin bottom aerators, and live bottom designs to handle materials with poor flow characteristics. Each silo features smooth-wall design, level sensors, and overfill protection, ensuring consistent and controlled discharge.
- Batching & Weighing systems
Macawber also offers fully integrated batching and weighing systems designed for high-precision dosing. This recipe management system for the paint industry utilises load cell-based gain-in-weight or loss-in-weight configurations, governed by automated recipe control. Whether operating sequentially or simultaneously, these solutions ensure consistent formulation, batch-to-batch accuracy, and streamlined changeovers for diverse paint formulations.
- Screw feeders & Isolation gates
To manage flow control and system isolation, we provide a full range of screw feeders and isolation gates. As a leading screw feeders manufacturer in India offer variable-speed control for accurate metering of bulk materials, while isolation devices such as knife gates, slide gates, and rotary valves ensure safe, dust-free separation of process zones. These components are designed to integrate seamlessly with both pneumatic conveying and downstream equipment like mixers or reactors.
- Customised automation for handling minor powders
In the paint and pigment industry, customised automation for handling minor powders includes precise micro dosing, pneumatic conveying, mechanical carousel transfer, and rail car systems. These tailored solutions ensure accurate ingredient handling, reduce contamination risks, improve efficiency, and support consistent batch quality in complex, multi-component pigment and paint formulations.
- SCADA control systems
All systems are governed by SCADA-based control architecture, offering centralised monitoring and recipe-driven automation. The SCADA platform provides real-time visualisation of conveying and batching operations, data logging, alarm management, remote diagnostics, and full traceability of every ingredient batch.

Unique Selling Points (USPs) of Our Design
- ASME Compliance
Macawber emphasises ASME standards when designing pressure vessels for pneumatic dense-phase conveying, ensuring safety, efficiency, and compliance. Adhering to specific codes and guidelines guarantees reliable operation.
- Dome Valves
The dome valve, crucial for regulating bulk powder flow, is the most wear-prone component. Macawber’s dome valves feature special hard coatings tailored to material properties and customer requirements, including ceramic, tungsten carbide, and frit coatings.
- Rotary airlock valves
Designs customised to handle plastic flakes with special non-pinning designs and venting arrangements suited for handling flakes.
- Heavy-Duty Design for Long Life
Macawber has been the leading pneumatic conveying system manufacturer in India, successfully supplying conveying solutions over the past 30 years across the Indian cement industry, thanks to a focus on heavy-duty design that results in extended equipment lifespan.
- Optimal Sizing Design
Based on required conveying capacity and corresponding air requirements, Macawber optimises vessel and pipeline sizes to meet critical performance parameters and energy efficiency.
- Healthy Filtration Area
Proper venting of air is essential before material is dropped at reception points. An inadequate filtration area can lead to back pressure and system malfunctions. Macawber prioritises a healthy filtration area for efficient venting.

FAQ's
Pneumatic conveying is preferred for paints and pigments because it offers a dust-free, enclosed method of transport, reducing contamination and product loss. It minimises material degradation, which is crucial for maintaining pigment quality and consistency. Additionally, it is efficient for handling bulk quantities while maintaining a clean and safe working environment.
Pneumatic conveying is a method of moving powdered or granular materials like pigments through a pipeline using air or gas flow. In the paint industry, it ensures smooth, continuous transport of pigments and other fine powders from storage to processing units. This system supports automation and maintains the integrity of sensitive materials.
Yes, pneumatic conveying systems can be tailored to handle the unique properties of different paint or pigment formulations. Customisations can include adjustments in airflow, pressure, and material of construction to prevent clogging, degradation, or contamination. This ensures efficient handling while preserving product quality and meeting production requirements.
