Establishing a roller press granualtor production line requires comprehensive planning across various aspects—including site layout, equipment selection, process matching, safety and environmental protection, and ease of operation and maintenance—to ensure stable operation, compliant granule quality, and efficient production capacity.

The site and layout must be rational; the workshop area should be planned based on the projected daily output, with adequate space reserved for raw material storage, finished product warehousing, maintenance activities, and internal traffic flow. Equipment should be arranged linearly according to the process workflow to minimize material transfer losses. The ceiling height must be sufficient to accommodate material feeding and maintenance requirements, while the flooring should be hardened to facilitate cleaning and support heavy loads.

Equipment selection and integration constitute the core of the project. A double roller pess granaultor should be selected based on the specific characteristics of the raw materials, with careful determination of the roller skin material, operating pressure, and die hole specifications. Auxiliary equipment—such as crushers, mixers, screening machines, and packaging machines—must be carefully matched to the capacity of the main granulator to prevent production bottlenecks. Additionally, dust removal and iron removal devices should be installed to prevent impurities from damaging the roller skins, thereby extending the service life of the fertilizer production machine.

Process parameters require precise control. The moisture content of the raw materials should be maintained within the range of 8% to 15%; excessive moisture causes material to stick to the rollers, while insufficient moisture prevents granule formation, and overly dry material results in loose, fragile granules. The uniformity of mixing and the feeding rate must remain stable to ensure constant pressure between the rollers, thereby preventing inconsistencies in granule size and minimizing the generation of excessive fines.

Safety and environmental protection cannot be overlooked. Protective guards must be installed on all transmission components, and electrical systems should be treated with waterproofing and explosion-proofing measures. Dust collection systems should be implemented to mitigate airborne dust pollution, and drainage and waste recycling systems must be rationally planned to ensure full compliance with environmental regulations.

Ease of operation, maintenance, and long-term usage is essential. Sufficient spacing should be left between equipment units to facilitate maintenance access, and an adequate inventory of critical wear parts should be kept on hand. Operators must undergo prior training to become proficient in pressure adjustment procedures and troubleshooting protocols. Regular inspections of roller skin wear and bearing lubrication, coupled with timely maintenance, are crucial for ensuring the long-term, stable operation of the production line.
