A custom order for a Malaysian client has recently been loaded into containers at Huaqiang Heavy Industry. The shipment includes four double roller extrusion granulator s, horizontal ribbon mixer s, and a full set of accessories; all items have been securely packed and are ready for ocean transport to the client's production site in Malaysia. To withstand long-distance sea transport, all main units are wrapped in multiple layers of stretch film to seal out moisture and prevent rust. Inside the containers, the equipment is tightly lashed and secured to prevent shifting or impact damage during transit. Smaller components—such as screws and seals—are boxed, labeled, and categorized to facilitate easy inventory checks upon delivery. The core equipment in this shipment is the double roller extrusion granulator . Utilizing a dry granulation process, it eliminates the need for water addition or drying, directly compressing powdered materials into uniform granules; it is ideally suited for...

The bustling container-loading scene marks the successful delivery of Huaqiang Heavy Industry's double-roller extrusion granulation production line order for Malaysia; the complete equipment set has been packed and is en route to the overseas project site. To ensure suitability for containerized sea freight, all equipment components were strategically disassembled, precision parts were wrapped in multiple protective layers, and on-site workers meticulously secured the loads to prevent damage from movement during transit—effectively managing the final quality checkpoint before shipment. Compared to traditional rotary drum or disc granulation processes, double-roller extrusion dry granulation technology offers distinct advantages: it requires no binders and utilizes ambient-temperature extrusion molding. This makes it particularly well-suited to Malaysia's tropical climate, effectively solving the issue of high drying costs associated with humid environments. The system produce...

Large rotary drum equipment sits securely on the flatbed truck; as the loading process concludes, the rotary drum granulation fertilizer production line —custom-built by Huaqiang Heavy Industry for a Nigerian client—officially sets off for the African continent, marking the start of a new overseas project journey. With many African nations vigorously promoting local fertilizer manufacturing to reduce reliance on imports, the market for fertilizer production equipment in Nigeria is experiencing rapid growth. The delivered rotary drum granulation line is capable of producing both organic and compound fertilizers. It processes various organic raw materials—such as crop stalks and livestock manure—using a wet drum granulation process to yield uniform, spherical, and durable fertilizer granules. These granules are easy to store, transport, and apply in the field, making them ideally suited to the needs of local farmers. To meet the specific requirements of this overseas project, Huaqiang He...

The biggest highlight of rotary drum granulator is its strong adaptability to raw materials. It covers almost all powdery and finely divided fertilizer raw materials. It does not require complicated modification processing and is suitable for the production of organic fertilizers, compound fertilizers, biological fertilizers and other categories. It can be divided into three major categories: 1. Organic raw materials Decomposed livestock and poultry manure (chicken manure, sheep manure, cow manure, pig manure), crushed straw, sawdust, fungus residue, sugar residue, sludge, kitchen fermentation materials, cakes and other agricultural and industrial organic waste are the core processing equipment of the organic fertilizer production line. 2. Compound fertilizer raw materials Basic chemical fertilizer powders such as urea, monoammonium phosphate, diammonium phosphate, potassium chloride, potassium sulfate, calcium magnesium phosphate fertilizer, bentonite, kaolin, etc. can process high, ...

  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...

Answer: The production of bio-organic fertilizer involves many processes and requires high levels of process control. New factories and those in mass production commonly encounter four main categories of common problems: fermentation, granulation, quality, and cost. These are also the core issues affecting fertilizer compliance and production efficiency. First is inadequate fermentation and composting. This is the most common problem in production, mostly caused by an imbalance in the dry-to-wet ratio of raw materials, improper inoculum addition, and untimely turning. This easily leads to incomplete fermentation, residual pathogens and insect eggs, root and seedling burn in the finished fertilizer, and may also be accompanied by a pungent odor, mold, and blackening, directly resulting in products that do not meet industry testing standards. Second is poor granulation formation. Excessive or insufficient moisture content in the composted material, uneven powder particle size, and chaot...
