Release time:2025-08-12 Views:14 Sources:Tai an Zhonglan Xuye Environmental Protection Technology Co., Ltd


The compound fertilizer equipment production line is a complete process system used for producing compound fertilizers, which has the characteristics of low investment, fast results, and good economic benefits. The following introduces the equipment composition, process flow, technical parameters, and equipment characteristics:

Equipment Composition

The compound fertilizer production line usually consists of the following equipment:

Mixing equipment: such as double shaft mixers and horizontal mixers, used to mix the prepared raw materials evenly and improve the overall uniform fertilizer efficiency content of fertilizer particles.

Granulation equipment: such as disc granulators, drum granulators, and extrusion granulators, used to feed uniformly stirred raw materials into the granulator for granulation.

Drying equipment: such as a drum dryer, used to feed the granules made by the granulator into the dryer, dry the moisture contained in the granules, increase their strength, and facilitate storage.

Cooling equipment: used to cool the dried fertilizer particles, prevent clumping, and facilitate bagging, storage, and transportation.

Screening equipment: such as a drum screening machine, used to grade the cooled particles. Unqualified particles are crushed and re granulated to screen out qualified products.

Induced draft dust removal equipment: used to treat dust generated during the production process to ensure environmental compliance.

Conveyor equipment: such as belt conveyors, used to transport raw materials and finished products between various devices.

Return material processing equipment: used to process unqualified particles, crush them and re pelletize them.

Equipment that can be added according to user needs, such as raw material processing equipment, anti caking wrapping equipment, and automatic measuring and packaging equipment.

technological process

The process flow of compound fertilizer production line can usually be divided into the following steps:

Raw material ingredients: Based on market demand and soil testing results in various regions, urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, dicalcium phosphate, tricalcium phosphate), potassium chloride (potassium sulfate) and other raw materials are prepared in a certain proportion.

Raw material mixing: Mix the prepared raw materials evenly.

Raw material granulation: Send the mixed raw materials into the granulator for granulation.

Particle drying: Send the particles made by the granulator into the dryer for drying.

Particle cooling: Cool the dried fertilizer particles.

Particle classification: Classify the cooled particles.

Finished product coating: Coat qualified products with coating to increase the brightness and roundness of the particles.

Finished product packaging: Pack the coated particles into bags for storage.

Technical Parameter

The technical parameters of the compound fertilizer production line vary depending on the equipment model and production scale. For example, some models of compound fertilizer production lines can produce 0.8 to 1.8 tons per hour, with particle diameters adjustable between 3.5 and 5.5 millimeters, and installed power ranging from 26 kW to 33 kW.
