  After daily shutdowns, promptly clean residual raw materials from the roller shells and feed hopper to prevent material caking and corrosion of the roller surfaces; do not use hard objects for scraping, as this can cause wear or tooth damage to the roller shells. Check the gap between the roller shells during every shift to ensure uniformity; make fine adjustments if the deviation is excessive to prevent uneven granule size. Regularly replenish grease in the gearbox and bearing housings—adding grease every three days and performing a complete oil change monthly—to prevent dry friction caused by a lack of lubrication. Clean dust from drive chains and belts, maintain proper tension (tightening them promptly if loose), and immediately replace any damaged parts. Before startup, check the tightness of all bolts—paying special attention to the roller pressing assembly and the machine frame's anchor bolts—to prevent loosening due to operational vibration. Strictly prohibit hard metal ob...

The overall arc structure design allows for a granulation rate of over 93%. This equipment has a simple structure, is easy to operate...

Bio-organic fertilizer is a core agricultural input for ecological agriculture. The efficiency and stability of the production line directly determine fertilizer quality, production capacity, and market competitiveness. Currently, many production lines suffer from uneven fermentation, rapid equipment wear and tear, and low finished product qualification rates. To improve quality and efficiency, efforts must be made in multiple aspects, including raw material control, process optimization, equipment operation and maintenance, and refined management, to comprehensively empower production. Strict control of raw material pretreatment is the foundation of efficient production. Raw material quality directly affects fermentation results. During production, the carbon-to-nitrogen ratio must be precisely controlled, adjusting the ratio of raw materials such as straw, livestock manure, and humic acid to the optimal range of 25-30:1. Simultaneously, the moisture content of the raw materials shoul...

Granulation is a core process in fertilizer production, turning powdered raw materials into uniform granules, improving fertilizer utilization, facilitating storage, and enabling mechanized fertilization. Based on production processes, raw material characteristics, and production capacity requirements, commonly used granulators in the fertilizer industry are mainly divided into four categories: disc granulators, rotary drum granulators, double roller press granulators, and flat die pellet machines. They are widely used in the production of various fertilizers such as organic fertilizers, compound fertilizers, and slow-release fertilizers. Disc granulator s are the mainstream equipment in small and medium-sized fertilizer production lines, with extremely high applicability. They rely on the centrifugal force generated by the rotation of an inclined disc to continuously roll and bind the powder into balls, achieving a granulation rate of over 90%. This equipment has a simple structure, i...

Based on the core principle of "transforming waste into treasure," the bio-organic fertilizer production line has established a unique production system that differentiates it from traditional chemical fertilizers and has become a key force in promoting the green transformation of agriculture. Its core advantage lies in transforming agricultural waste into functional fertilizers rich in active bacterial communities, achieving both ecological and economic benefits. A notable feature is its diverse raw material system. The production line can process a variety of organic wastes, including livestock and poultry manure, crop straw, and food waste. Through pretreatment processes such as crushing and mixing, the carbon-nitrogen ratio of each material is adjusted to an optimal range for fermentation. For example, mixing chicken manure with corn straw in a specific ratio not only balances the composting rate of high-nitrogen raw materials, but also utilizes straw fiber to improve fer...

In the fertilizer production line , the working efficiency of the flat die granulator directly affects the production capacity and cost. Mastering scientific methods to improve its efficiency can inject strong power into production. Material pretreatment is the basis for improving efficiency. The raw materials need to be screened to remove impurities such as stones and metals to avoid damage to the pressing wheel and die plate. For coarse fiber materials, such as straw and sawdust, they can be crushed first to make the material particle size more uniform and reduce the resistance during granulation. At the same time, control the moisture content of the raw materials. Too high will easily lead to blockage of the die hole, and too low will make granulation difficult. According to the characteristics of the material, adjust the moisture content to an appropriate range to make the granulation process smoother. Equipment debugging needs to be precise. The gap between the pressing wheel and...
