Introduction

Putty powder, also known as wall putty or skim coat, is a crucial material in construction for smoothing and finishing walls before painting. A well-designed putty powder production line ensures high-quality, consistent output for various construction applications. In this blog, we’ll explore the key components, working process, and benefits of a modern putty powder production line.

What is Putty Powder?

Putty powder is a mixture of:

• Binders (e.g., white cement, gypsum, or lime)

• Fillers (e.g., calcium carbonate, talc, or quartz powder)

• Additives (e.g., cellulose ether, redispersible polymer powder)

It improves wall adhesion, crack resistance, and smoothness, making it essential for interior and exterior wall coatings.

Putty Powder Production Line Components

A fully automated putty powder production line includes:

1. Raw Material Storage System

   • Silos for cement, fly ash, and other bulk materials

   • Hopper for additives

2. Weighing & Batching System

   • Precision scales for accurate ingredient measurement

   • Automated control system for consistent mixing ratios

3. Mixing System

   • Horizontal Ribbon Mixer (for dry powder blending)

   • High-Speed Disperser (for wet mixing if required)

4. Packaging System

   • Valve bagging machines for 20kg–50kg bags

   • Bulk loading for large-scale distribution

5. Dust Collection System

   • Cyclone separators & bag filters to minimize pollution

6. Control Panel

   • PLC-based automation for precise operation

Production Process Flow

1. Raw Material Feeding – Ingredients are transported to storage silos.

2. Weighing & Batching – Each component is measured according to the formula.

3. Mixing – Dry materials are blended uniformly (5–10 minutes per batch).

4. Packaging – The finished putty powder is packed into bags or bulk containers.

5. Quality Control – Samples are tested for fineness, adhesion, and workability.

Advantages of an Automated Production Line

✅ High Efficiency – Produces 5–30 tons per hour (depending on capacity).
✅ Consistent Quality – Eliminates human error in mixing ratios.
✅ Low Labor Cost – Requires minimal manual intervention.
✅ Customizable Formulas – Adjust recipes for different putty types (e.g., waterproof, flexible).
✅ Eco-Friendly – Dust control systems reduce environmental impact.

Conclusion

Investing in a putty powder production line enhances productivity, ensures product uniformity, and meets growing construction demands. Whether for small-scale or industrial manufacturing, automation improves efficiency and profitability.

If you're planning to set up a putty powder plant, consider factors like raw material availability, production capacity, and automation level to optimize your production line.
