Zero Shear Dosing Technology
In the realm of continuous fertilizer blending, the blend controller’s role is not limited to controlling the total amount of fertilizer dosed but also extends to regulating the dosing rate. This necessitates a variable rate dosing mechanism, exemplified by an auger driven by a variable speed motor. The rotation speed of the auger directly influences the fertilizer dosing rate. These dosing methods, originally developed by the bulk handling industry, are not always ideally suited for the unique properties of granulated fertilizer. Zero Shear dosing technology addresses several critical aspects of the blending process: efficiency, accuracy, preservation of fertilizer granules’ integrity, and minimizing dust formation.
Key aspects of Zero Shear dosing technology include:
- Granule Preservation: Traditional dosing methods, such as augers or rotary valves, often subject fertilizer granules to shear forces, potentially causing damage. The Zero Shear dosing method employs a servo-driven mechanism that remains largely stationary during dosing, minimizing the impact on the granules and preserving their integrity.
- Dust Reduction: Shearing of fertilizer granules can lead to the creation of dust particles, posing challenges for worker safety, environmental concerns, quality control, and maintenance.
- Accuracy: The gate component in Zero Shear technology is driven by a servo motor, enabling extremely precise control of the dosing rate, adjustable to increments as small as 0.003 millimetres
The advent of Zero Shear dosing technology marks a significant milestone in the fertilizer blending industry and agriculture at large, enhancing product quality, promoting environmental sustainability, improving operational efficiency, and leading to lower maintenance costs with its unravelled mechanical simplicity.
Fully Integrated Control Systems
Despite the outward simplicity of Zero Shear dosing technology, the control systems required to manage such a device are complex, surpassing the mere variation of motor speed. Servo motor technology, which has been around for decades, was traditionally perceived as expensive and technically challenging. However, with the advent of economies of scale and significant advancements in software and electronics, servo motors have become a common feature in automation industries. Nevertheless, they require sophisticated, integrated control systems for effective operation. These systems enable seamless communication between all devices in a blending plant via a high-speed network, either directly or through the main control unit. Unlike standalone, process-specific controllers that manage each process independently, a fully integrated control system oversees the entire operation. This system enables highly customized configurations of blending plants, allows for future expansions and upgrades, and most importantly, offers unrivalled levels of diagnostics. It is the operational heart of the blending plant.

Yet, the brilliance of Bagtech’s approach lies in addressing a common challenge: the often arduous task of identifying faults within these systems, which can be both time-consuming and complex. By harnessing the power of digital safety systems and seamlessly connecting them to the plant’s control system, Bagtech has enabled sophisticated digital communication right down to the level of individual safety sensors. This integration has unlocked the potential for precise diagnostics and unparalleled flexibility in operations. The plants are now ingeniously segmented into distinct safety zones at the software level, a futuristic approach that ensures that the operation in one zone can continue unhindered even when another zone enters a safe mode. This strategic segmentation not only enhances safety but also significantly minimizes downtime, propelling Bagtech’s blending plants into a new era of operational efficiency and safety.
Liquid Coating On-The-Fly
Liquid coating of granular fertilizers is a cutting-edge technique in modern agriculture, enhancing nutrient efficiency and environmental sustainability. This process involves applying a specifically formulated liquid coating, which can include nutrients, pesticides, or conditioners, to fertilizer granules. The primary advantage is the controlled release of nutrients, which reduces leaching and runoff, particularly in areas with high rainfall or irrigation. This slow release also decreases the need for frequent fertilizer applications, saving labor and time.
A notable advantage of liquid coating is its ability to amalgamate multiple nutrients or additives into a single granule, streamlining the application process for farmers. This method not only optimizes plant growth but also reduces environmental impact by minimizing nutrient runoff, thus safeguarding nearby water bodies from eutrophication and promoting more efficient resource utilization.
Additionally, liquid-coated fertilizers possess enhanced physical properties, such as reduced dust generation and improved flowability, which facilitate handling and application. The coating also protects the fertilizer from environmental factors, extending its shelf life and maintaining its efficacy. Overall, the liquid coating of granular fertilizers presents a beneficial approach in agriculture, offering improved nutrient delivery, environmental benefits, and ease of application.
Bagtech has observed a marked increase in demand for liquid coating, with an influx of suppliers introducing their unique liquid coating products. A significant effort has been dedicated to developing systems to accurately dose and coat these liquid products, a challenging task due to the varying compositions of these products, ranging from oil-based to water-based, and from low to high viscosity, and including solids in suspension. The integrated control system plays a pivotal role in managing this complexity.
Typically, the liquid coating application is either a pre-blend or post-blend step. Pre-blending involves coating raw materials in bulk before they are blended with other components. Post-blending coating occurs after the blending process, ensuring an even coating on all ingredients in the blend. To enhance efficiencies and reduce handling, Bagtech has innovated coating equipment that integrates into the blending plant, enabling both pre-blend and post-blend coating in a single continuous production run.
A common scenario involves a blend of Urea, MAP, and KCL. Initially, the Urea requires a coating of a slow-release agent. It is then blended with MAP and KCL in controlled proportions, followed by an even coating of the entire blend with a liquid Zinc nutrient additive. Traditionally a three-step process, Bagtech’s integrated coating solution consolidates this into a single continuous operation. This is achieved by incorporating a coating blender into one or more of the raw hoppers, along with variable rate liquid dosing pumps, all meticulously controlled by the integrated control system to match the rate of liquid with the fertilizer rate continuously.
