The key equipment and processes you need to understand when investing in a granular organic fertilizer production line. Due to the lightweight texture of organic fertilizers, their powder form is easily affected by wind during application, and there is also a risk of machine jamming during machine sowing. Therefore, many organic fertilizer producers choose to process organic fertilizers into granules. So, how much capital investment is needed to build an organic fertilizer production line? Next, we will delve into this issue in depth.

Overview of Key Equipment

In order to improve the efficiency and quality of material granulation, wet granulation technology has become a key process in organic fertilizer production. Compared to powdered organic fertilizer production lines, granular organic fertilizer production lines also add drying and cooling processes in addition to the granulation process. Drying is achieved by evaporating the moisture in the particles at high temperatures, while cooling is achieved by cooling the particles to near room temperature for coating and bagging.

Composition of organic fertilizer production line

Firstly, let briefly understand the composition of a basic granular organic fertilizer production line. This production line includes fermentation equipment, raw material storage, conveyor belt, crusher, screening machine, granulator, dryer, cooler, re screening machine, elevator (conveyor belt), and packaging scale. In the second screening stage, a conveyor belt can be used to return the unqualified particles to the crushing stage for re granulation. This production line layout is suitable for the production of organic fertilizers with single raw materials and less strict ratios.

Depending on the selected equipment and specifications, the reasonable price range for this production line is approximately between 300000 and 500000 yuan.

Coating and Agglomeration Prevention

To prevent organic fertilizers from clumping during production, a coating process can be added before bagging after screening. Simply put, this step involves covering the surface of organic fertilizer particles with a protective film to effectively prevent clumping and enhance the product market competitiveness. The price of the coating machine depends on its model and specifications, roughly ranging from 50000 to 100000 yuan.

Ingredient equipment and mixing equipment

For organic fertilizer production lines with a wide variety of raw materials and strict proportioning requirements, additional batching equipment and mixing equipment need to be added. The starting price for these devices is 30000 yuan, and the specific price will depend on the selected model and specifications.

Requirements for environmental protection equipment

For raw materials such as pig manure, distiller grains, hotel swill, and underwater sludge, solid-liquid separation treatment is usually required before entering the fermentation process. In this stage, the price range of the solid-liquid separator is approximately between 10000 and 20000 yuan. In addition, in areas with strict environmental standards, it may be necessary to install dust removal equipment to ensure the approval of environmental impact assessments and the normal operation of factories. The price of such devices depends on the specific model and specifications, usually ranging from 30000 to 100000 yuan.

The above is an overview of the various stages and equipment required for the production line of granular organic fertilizer. Enterprises can flexibly configure their organic fertilizer production lines based on their own production needs and investment budgets. Next, we will provide a detailed introduction to the specific equipment types involved in each stage.

Detailed introduction of equipment types

Drying and cooling equipment

In terms of drying and cooling equipment, we provide rotary dryers and rotary coolers to ensure that the raw materials are fully dried and cooled. In the screening process, we are equipped with drum and vibrating screening machines, which can choose different levels of screening according to needs, such as three-stage screening or two-stage screening. In addition, a rotary coating machine has been introduced to efficiently coat organic fertilizers. To meet different packaging needs, we offer spiral and DC automatic packaging equipment, as well as multiple options such as single head and double head.

Dehydration and dust removal equipment

In terms of dehydration equipment, we provide solid-liquid separators and inclined screen dehydrators to effectively achieve solid-liquid separation and dehydration of raw materials. At the same time, in order to meet the dust removal needs, we are equipped with water curtain dust collectors and cyclone dust collectors to ensure effective control of dust during the production process.
