The Importance of Chemical Additives in Dry Mix Mortar Production Line

Chemical additives play a critical role in determining the quality and performance of dry mix mortar. These additives enhance workability, adhesion, water retention, and durability, making them indispensable in modern construction materials. However, the precise dosing of additives is crucial—too little may result in poor performance, while too much can lead to excessive costs or adverse effects on mortar properties.

High-Precision Metering Systems for Chemical Additives

To ensure consistent mortar quality, accurate metering and delivery systems are essential. The most reliable systems feature:

• Stainless Steel Construction: Metering equipment is typically made of stainless steel to resist corrosion and ensure long-term durability.

• Precision Screw Conveyors: The metering screws are usually housed in 140 mm or 133 mm stainless steel tubes, providing smooth and consistent additive flow.

• High-Accuracy Gear Reducers: K-series helical gear reducers are commonly used due to their high precision, ensuring minimal deviation in additive dosing.

Efficient Delivery of Additives to the Mixer

Once accurately measured, chemical additives must be efficiently transported to the mixer. The most effective method is:

• Negative Pressure (Vacuum) Feeding: This system sucks additives into the mixer using pneumatic suction, preventing segregation and ensuring uniform distribution. This method is dust-free, energy-efficient, and ideal for handling fine powders.

Conclusion

The quality of dry mix mortar heavily depends on the precise metering and delivery of chemical additives. By using stainless steel metering systems, precision screw conveyors, and high-accuracy reducers, manufacturers can achieve consistent dosing. Additionally, negative pressure feeding ensures efficient and contamination-free transfer to the mixer. Investing in advanced metering and delivery systems is essential for producing high-performance dry mix mortar.TEL:+8615137127837
