Automatic Rotary Monoblock with Sealed Hopper for Challenging Products

LDP-200 Sealed Hopper Rotary Monoblock for Dusty & Aggressive Powders.

Contained, Efficient and Clean Packaging for Demanding Materials

The LDP-200 Automatic Rotary Monoblock is a robust, carousel-style solution built to solve the most difficult packaging challenges. It is specifically designed for products that are dusty, abrasive, or otherwise problematic for standard packaging equipment. The integrated sealed hopper system is the core of this design, creating a closed loop that prevents product escape, ensuring a clean, safe, and efficient operation while minimizing product loss.

The LDP-200 Automatic Rotary Monoblock tackles the specific challenges of packaging fine, lightweight powders that tend to generate significant dust. This machine transforms a messy and problematic process into a clean, closed, and highly efficient operation. The combination of a precision screw dispenser and a robust dust extraction system guarantees high accuracy while maintaining a safe and clean factory environment, protecting both your product and your workforce .

Advanced Dust Control & Precision Dosing

The machine’s effectiveness lies in its specialized components:

• Screw Dispenser (Auger Filler): Provides gentle, precise volumetric dosing of fine powders, minimizing air entrapment and product compaction for exceptional weight accuracy .

• Integrated Dedusting System: Actively captures dust particles at key points, such as during filling and sealing, preventing them from escaping into the atmosphere .

• Closed-Loop Design: The machine is designed to contain the product, with features like "No pack – no product" functionality to prevent spillage .

Sealed Hopper & Screw Dispensing Technology

This machine combines two critical technologies for handling sensitive materials:

• Hermetically Sealed Hopper: This fully enclosed system is engineered to prevent dust from escaping into the atmosphere, making it ideal for aggressive, dusty powders that can be hazardous or simply wasteful. It protects operator health and maintains a clean production line.

• Precision Screw Dispenser (Auger Filler): Provides gentle, consistent, and highly accurate volumetric dosing. It is perfectly suited for everything from free-flowing granules and dusty powders to thick, pasty substances, ensuring reliable performance without bridging or clogging.

Complete Automated Packaging Cycle

The rotating dial of the LDP-200 executes a seamless, automated sequence:

1. Pouch Pickup & Positioning

2. Pouch Opening & Air Purging (with filtered air if needed)

3. Precision Filling within the controlled, sealed environment

4. Hermetic Heat Sealing

5. Package Marking/Date Coding

6. Finished Product Discharge

7. Active Dust Extraction during the filling process

Standard Integrated Equipment

This monoblock is supplied as a complete, ready-to-run system, including:

• Receiving Hopper with Screw Feeder: Ensures a consistent and controlled supply of product to the main sealed hopper.

• Checkweigher (Weight Rejector): Provides 100% quality control by automatically weighing each finished pouch and rejecting any that are outside the specified tolerance, ensuring compliance and reducing giveaway.

Target Industries & Product Applications

This machine is perfectly suited for a wide array of demanding products:

• Chemical & Industrial: Abrasive cleaning powders, cement additives, fine chemicals, pigments, and granular fertilizers.
