Mixing Wet Granulator

UnionPack’s Fully Automated Intelligent High-Efficiency Mixing Wet Granulator combines advanced technologies in optics, electronics, and pneumatics. The system uses a Siemens PLC microcontroller for precise control and includes touch-screen operation with infinite variable-frequency speed control. 

The design features several innovative functions, including:

Automatic Adhesive Application: The granulator includes a unique system for automatically spraying or dripping adhesive into the mixture, improving granule uniformity and consistency.

Vacuum Feeding: A vacuum system ensures efficient material feeding into the granulator, reducing product loss and enhancing production efficiency.

Vibration Dust Removal: The machine’s built-in vibration dust removal system minimizes the contamination risk and ensures cleaner production.

Safety Protection: Multiple safety features ensure operational safety during the granulation process, preventing accidents.

Cooling & Humidity Control: The jacketed cooling system and humidity control regulate temperature and moisture, ensuring stable and efficient granulation.

This technology drastically reduces adhesive consumption by up to 25% compared to traditional methods and shortens drying times. The granules produced have uniform particle size, high hardness, and excellent pelletization, making the machine suitable for a wide range of industries.

LM Series (LM-10 to LM-800) can efficiently granulate various powdery and pasty materials into solid particles with uniform size and high sphericity. It is particularly advantageous for producing granules used in the pharmaceutical, chemical, metallurgy, and other industries. Notably, it can granulate Chinese medicinal herb extracts and powders, addressing a significant challenge in traditional Chinese medicine production.

Features and Innovations: 

Infinite Speed Control: Unlike traditional granulators that use fixed speed ratios between mixing and granulating blades, the LM Series uses variable frequency drive (VFD) technology. This provides infinite adjustable speed ratios for both the mixing paddle and granulating knife, allowing for more precise control tailored to various materials and processes.

Program Control with Memory Storage: Traditional granulators lack programmable control and batch-specific parameter storage. LM Series features an intelligent PLC system that stores multiple batch parameters and recipes. This allows for consistent granulation quality across different production runs and enables one-touch recall of settings for repeat production.

Reduced Adhesive Use: The innovative design and precise control of adhesive application reduce adhesive consumption by up to 25%, resulting in shorter granulation and drying times, and contributing to higher cost efficiency.

Superior Granulation Performance: The granulator produces irregularly shaped granules with a wide particle size distribution. Granules have strong compressibility, good solubility, and moderate breathability. The final granule size can be adjusted by changing the mixing and granulating speeds—slower speeds produce larger granules, and faster speeds result in smaller granules. This flexibility is ideal for different materials and applications.

Hygienic and Safe Design: The granulator incorporates a sealed system to prevent dust contamination and supports water-based cleaning of the sealing chamber to avoid cross-contamination. The drive shaft is sealed with inflatable seals to protect the internal components from dust and moisture.
