Uneven feeding during production in a double roller press granulator directly affects the quality of the finished product, equipment lifespan, and production efficiency, leading to numerous adverse effects.
Firstly, it severely impacts the quality of the finished granules. Excessive feeding results in over-compacted material, producing larger and harder granules; insufficient feeding leads to insufficient extrusion force, producing loose, broken, and hollow granules, resulting in significant variations in particle size and appearance. Simultaneously, the large differences in particle strength increase the number of defective products, drastically reducing the finished product forming rate, causing a large amount of powder to be recycled and reworked, making it difficult to meet product qualification standards and market demand.
Secondly, it exacerbates equipment wear and causes operational malfunctions. Uneven feeding causes uneven force on the extrusion rollers, resulting in localized wear on the roller skin, accelerating wear and aging, and shortening service life. Frequent fluctuations in hydraulic pressure and repeated cylinder adjustments can easily lead to oil leaks; fluctuating loads on transmission components can generate abnormal noises and overheating, accelerating damage to gears, bearings, and reducers. In severe cases, material jamming, equipment tripping, and shutdowns can occur, disrupting normal production.
Ultimately, this leads to increased production costs and decreased capacity. Uneven feeding disrupts the production process, resulting in actual capacity being far below standard output. Increased rework material increases equipment load and significantly raises power consumption. Frequent equipment maintenance and sorting of defective products consume substantial manpower and resources, further increasing production expenses. In addition, insufficient material compression causes unstable physical and chemical properties of the product, making it prone to breakage and clumping during subsequent storage, severely impacting overall production efficiency.
