Automatic Dosing System with High Accuracy for Powder Material
Processing
The Automatic Dosing System is designed for accurate weighing,
dosing, and automatic feeding of powder, granules, and additives in
industrial production. The system automatically controls each
material according to preset recipes, improving production
efficiency while reducing manual operation and material waste.
The equipment adopts a modular structure that integrates storage
silos, weighing hoppers, feeding units, screw conveyors, vacuum
conveying systems, and an intelligent PLC control system. Operators
can easily manage multiple formulas through the touch screen,
allowing fast product changes and stable production performance.
The weighing process is monitored continuously by high-precision
load cells. Once the preset weight is reached, the feeding unit
stops automatically, ensuring excellent dosing accuracy and
repeatability. This automatic control minimizes human error while
maintaining consistent product quality.
The system supports both batch and continuous production. After
weighing, materials are automatically transferred to mixers,
storage bins, extrusion lines, or other downstream equipment,
creating a fully automated material preparation process.
Designed for flexibility, the Automatic Dosing System can be
configured with different numbers of material stations, weighing
capacities, and conveying methods according to customer
requirements. It can also be integrated into existing production
lines or supplied as part of a complete turnkey material handling
solution.
The system is widely used in plastics, chemicals, food processing,
building materials, masterbatch production, recycling, and many
other industries where accurate material dosing is essential for
maintaining stable production quality.

Application Industries
The Automatic Dosing System is widely applied in industries that
require accurate material batching and automatic weighing. It is
commonly used in PVC compounding plants, SPC and WPC flooring
production, plastic granule manufacturing, masterbatch processing,
chemical powder production, rubber processing, food ingredient
preparation, and building material manufacturing. The system is
also suitable for recycling plants, mineral powder processing, and
other industrial applications where multiple raw materials must be
weighed accurately before mixing or further processing. By
providing stable and repeatable dosing performance, the system
helps manufacturers improve production efficiency while maintaining
consistent product quality.

Applicable Materials
The system is suitable for handling a wide variety of dry bulk
materials with different densities and flow characteristics. It can
accurately dose PVC resin, calcium carbonate, talc powder, titanium
dioxide, stabilizers, lubricants, pigments, fillers, plastic
granules, recycled plastics, masterbatch, mineral powders, chemical
additives, and many other industrial raw materials. Depending on
the material properties and production requirements, different
feeding methods such as screw conveyors, vacuum conveying systems,
or pneumatic conveying systems can be selected to ensure stable
feeding performance and high weighing accuracy throughout the
production process.
Optional Configuration
To meet different production requirements, the Automatic Dosing
System can be equipped with a variety of optional equipment and
intelligent control functions. Customers may choose storage silos,
weighing hoppers, vacuum conveying systems, screw conveyors,
automatic feeding stations, dust collection systems, centralized
material conveying systems, barcode management, MES communication,
recipe management software, and remote monitoring functions. The
equipment can also be connected with hot and cold mixers, ribbon
mixers, extrusion lines, packaging systems, and other automated
production equipment, providing a complete material handling
solution for modern factories.
