Roller Press Extrusion Fertilizer Production Line

The core equipment of the roller-pressed round pellet extrusion line is the double-roll extruder, whose working principle relies on two rollers rotating relative to each other. The raw materials are evenly fed between the rollers and pressed into dense round pellets under high pressure.

First, the raw materials are conveyed to the feed port of the double-roll extruder through a feeder. Then, under the strong extrusion of the rollers, the powdered raw materials are compressed and formed into regular pellets. These pellets are then passed through a screening device, and the pellets that do not meet the standards are separated and returned for further processing. Qualified pellets are conveyed to the next step of cooling and drying.

The whole process ensures high yield and pellet uniformity. By adjusting parameters such as roller gap, speed and pressure, the production line can flexibly produce pellets of different specifications to meet market demand. This efficient production method not only improves production efficiency, but also reduces production costs.

1) The requirements for raw materials of the roller-pressed round pellet extrusion production line are mainly concentrated on particle size and moisture content. In order to ensure the molding quality of the pellets, the raw material particles need to be uniform and fine, generally required to be less than 0.3 mm.

2) The moisture content of the raw materials is also a key factor, which should not exceed 5%. Excessive moisture may cause the pellets to stick together, affecting the molding effect and equipment operation efficiency. The raw material ingredients must have a certain plasticity and adhesion to form dense and stable pellets during the extrusion process.

3) When mixing different raw materials, pay attention to their chemical properties to avoid reactions or instability. Through scientific raw material ratios and strict quality control, it can be ensured that the produced granular fertilizers meet market standards and customer needs. Therefore, choosing the right raw materials and their processing process is the key to ensuring efficient operation of the production line and product quality.

The production capacity of roller-pressed round granule extrusion production lines is an important indicator of its efficiency, which is usually related to equipment specifications, raw material characteristics and operating conditions. In general, the production capacity of small and medium-sized production lines can reach 0.5 tons to 5 tons per hour, and large production lines can even have higher production capacity under optimized configuration.

The specific production capacity is also affected by factors such as raw material fluidity, particle size and equipment configuration. By adjusting parameters such as roller gap and speed, the production line can adapt to different production capacity requirements. In addition, by increasing the number of equipment or optimizing the process flow, the overall production capacity of the production line can also be significantly improved.

Modern production lines also use automated control systems to achieve real-time monitoring and adjustment of the production process, thereby improving production efficiency and product consistency. Stable and efficient production capacity output enables the production line to meet the market demand for fertilizers of various specifications and ingredients, while reducing operating costs and improving economic benefits.
