Flat Die Granulation Production Line: A High-Efficiency Granulation Manufacturing Solution

Flat die pelleting production lines play a vital role in modern industrial production, improving the efficiency of material storage, transportation, and utilization by processing powdered materials into uniform granules. This article introduces the production line's capacity characteristics, applicable materials, working principle, and selection recommendations to help global readers gain a comprehensive understanding of this technology. Production Capacity Overview The hourly output of flat die pelleting production lines varies significantly depending on the model, configuration, and material characteristics. Common small production lines (such as those used in laboratories or small-batch production scenarios) typically have an hourly output between 0.08 and 0.3 tons, with a power configuration of approximately 5.5 to 11 kW. Medium-sized production lines are suitable for small to medium-sized farms or fertilizer plants, with an hourly output of 0.4 to 2.5 tons and a power configuration of 15 to 55 kW. Large production lines are used for large-scale production, with an hourly output of 2.5 to 5 tons and a power configuration of 55 to 75 kW. For extra-large customized production lines, the hourly output can even reach 8 to 20 tons, with power requirements exceeding 90 kW. Key factors affecting production capacity include material moisture content, particle size, viscosity, hardness, as well as die orifice diameter and roller pressure. Generally, the material moisture content should be controlled between 15% and 25%, the particle size is preferably less than 2 mm, and the die orifice diameter commonly ranges from 3 to 30 mm. Proper control of these parameters helps improve pelleting yield and production efficiency. Main Application Areas: Flat die pelleting technology is widely used in multiple industries. In the fertilizer industry, it is suitable for the production of organic fertilizers, bio-organic fertilizers, and compound fertilizers. Raw materials include livestock and poultry manure, straw, and humic acid, with a pelleting yield typically exceeding 95%, high particle strength, and low secondary pulverization rate. In the feed industry, this technology is used to produce livestock, poultry, and aquatic pellet feed, retaining nutrients while maintaining a temperature rise below 30 degrees Celsius during processing. In the biomass energy sector, flat die pelleting can compress raw materials such as sawdust and straw into high-density fuel pellets, facilitating storage and combustion. Furthermore, this technology is also suitable for the chemical and mining industries, such as the pelleting of activated carbon, catalyst carriers, and mineral powders, especially suitable for low-viscosity and heat-sensitive materials. Working Principle and Structural Features: The flat die granulator works by using a motor-driven reducer to rotate the flat die. Under centrifugal force, the pressure rollers adhere to the die, forcing the material into the die holes and extruding it into cylindrical granules. Finally, a scraper cuts the granules into uniform lengths. The entire process is carried out at low temperatures (typically below 30 degrees Celsius), making it suitable for processing heat-sensitive materials.
