The double-roll extrusion granulation fertilizer production line adopts a dry granulation process to press the powdered material into 2-10mm granular materials through extrusion and supports customized molds.
The double-roll extrusion granulator is generally suitable for the production of granular fertilizers such as chemical fertilizers, compound fertilizers, inorganic fertilizers, and biological organic fertilizers. It can also be used to produce graphite particles, snow-melting agents, desiccants, bentonite cat litter, and other powdered materials. This production line has the characteristics of high efficiency, energy saving, and environmental protection. It is equipped with an automated control system to ensure the stability and high quality of granulation production and meet the fertilizer production needs of large, medium and small enterprises.
Advantages of Dry Granulation
1. Environmental protection and energy saving: no need for drying and cooling after granulation, saving energy consumption.
2. High particle hardness: the particle density produced by dry granulation is high, and no additives are required in the granulation process.
3. Wide range of applications: low requirements for the moisture content of raw materials, suitable for granulation of various powdery materials.
4. Avoid agglomeration: During the wet granulation process, the raw materials will agglomerate due to excessive moisture. Dry granulation avoids this situation and ensures the uniformity and quality of the granules.
How to produce high-quality granular fertilizer?
Fertilizer equipment included in the roller extrusion granulation production line
1. Automatic batching system: complete automatic proportioning according to demand, equipped with a remote monitoring system, the batching process can flexibly adjust the formula to ensure the nutrient content and quality of the raw materials are stable.
2. Conveying system: the material is accurately delivered to the target area through a belt conveyor or a bucket elevator, equipped with a dust protection device.
3. Crusher: the material can be quickly crushed to the ideal particle size.
4. Mixer: fully stir and mix the material to achieve the purpose of homogenization.
5. Roller extrusion granulator: the processed raw materials are squeezed and granulated in one time. No additives are required, the granules are of high hardness and low return rate.
6. Screening machine: classify the finished granules and remove impurities. The granules that do not meet the requirements are sent to the crushing mixer through the conveying system for re-granulation.
7. Packing machine and palletizer: the final finished granules are packaged and stacked by the weighing packaging system. It is convenient for the storage, transportation and sales of fertilizer granules.
Strictly controlling each link in the entire fertilizer production process can ensure the quality and stability of granular fertilizers. Timely adjusting production processes and formulas can effectively improve product quality and market competitiveness.
