In the realm of sustainable agriculture and waste management, the roller extrusion granulation machine has emerged as a crucial technology for compost granule making. This machine is specifically designed to transform organic waste into uniform, high-quality granules that can be used as an efficient fertilizer. In this blog, we will delve into the working principle, feeding moisture requirements, output granule size, and other essential aspects of the roller extrusion granulator.
Working Principle
The roller extrusion granulator working priciple is dry granulation, utilizing mechanical pressure to compact and form granules without the need for a liquid binder. The process begins with the raw compost material being fed into the granulator. Two counter-rotating rollers, equipped with matching cavities, apply pressure to the material. As the compost passes through these rollers, it is compacted into dense, uniform granules. These granules are then expelled from the machine and can be screened to achieve the desired size distribution.
The key advantage of this method is its efficiency and simplicity. Unlike wet granulation methods, there is no need for drying phases, which significantly reduces energy consumption and operational costs.
Feeding Moisture
One of the critical factors in the successful operation of a double roller press machine is the moisture content of the feed material. Optimal feeding moisture is crucial to ensure that the compost is sufficiently pliable to be compacted, yet dry enough to prevent sticking to the rollers. Typically, the moisture content should be between 10% and 20%. If the moisture level is too low, the material may not compact properly, leading to weak or incomplete granules. Conversely, if it is too high, the material may adhere to the rollers, causing blockages and inefficiencies.
Output Granules Size
The size of the output granules is another important consideration. The roller extrusion granulator is capable of producing granules in a variety of sizes, typically ranging from 3mm to 10mm in diameter. The size can be adjusted by changing the roller design or by using different screens to separate the granules post-extrusion. Smaller granules are generally preferred for more even distribution in soil, while larger granules may be used for specific agricultural applications where slower nutrient release is desired.
