Turning waste into treasure: A practical guide to making granules from mushroom and herbal medicine residues

by organic fertilizer production line

With the widespread adoption of environmental protection concepts, mushroom mycelium residue and traditional Chinese medicine residue can be transformed into practical granules for use in agricultural fertilization, biofuels, and other fields. The following are the key steps for efficient granulation.

Raw material pretreatment is fundamental. Fresh mushroom residue has a water content exceeding 70%, so it needs to be air-dried or oven-dried to 30%-40%, with frequent turning to prevent mold. Herbal medicine residue should be screened to remove impurities; hard lumps of roots and stems need to be crushed to a particle size of less than 5 mm using a fertilizer crusher. The two are mixed in a ratio of 3:1 or 2:1 (increasing the proportion of mushroom residue for fertilization, and increasing the proportion of herbal medicine residue for fuel), and a small amount of straw powder or bran is added to adjust the hardness and improve granulation stability.

The granulation process requires attention to operational details. Select a flat die pelleting machine or ring die pelleting machine, and preheat the mold to 60-80℃ before starting to prevent sticking. Feed the material at a uniform speed; if the granules are loose and easily broken, spray a small amount of water (not exceeding 2% of the total raw material); if the hardness is too high, reduce the moisture content. Regularly check the particle diameter and adjust the mold aperture to obtain standard 5-8 mm granules.

Finished product processing and application are also crucial. Newly made granules need to be spread out and cooled to room temperature, and then screened with a fertilizer screener machine to remove broken pieces (broken pieces can be returned to the machine for reprocessing). After cooling, pack them in sealed bags and store them in a dry and ventilated place; the shelf life is 6-8 months. In agriculture, they can be used directly as organic fertilizer to improve soil; they can also be used as feed additives for livestock and poultry (provided the herbal medicine residue is tested for harmful residues); and they can also be used as fuel, burning efficiently with low pollution.

This method not only achieves the resource utilization of waste but also reduces production costs. Whether for farmers or small processing plants, this method can be tried according to actual needs, truly achieving “turning waste into treasure.”

Large wheel compost turning machine: A high-efficiency pretreatment solution for fertilizer granulation production

by organic fertilizer production line

In modern fertilizer production systems, the large wheel compost turning machine plays a crucial pretreatment role. Although not directly involved in the final granulation stage, this equipment is key to ensuring the efficient operation of subsequent granulation equipment.

As the large wheel compost turning machine slowly moves through the fermentation field, it is creating the ideal raw material foundation for the entire production line. The massive disc rotates steadily, evenly turning the fermented material. This seemingly simple action actually determines the success or failure of the subsequent granulation process. Raw materials carefully processed by it exhibit better plasticity and forming rate, whether fed into a rotary drum granulator for agglomeration or a flat die pelleting machine for pressing.

In modern fertilizer production lines, the value of the large wheel compost turning machine is increasingly prominent. It provides stable, uniformly moist raw materials for the new type two in one organic fertilizer granulator, allowing this multi-functional equipment to fully utilize its technological advantages. Similarly, for equipment like ring die pelleting machines that have high requirements for raw materials, the raw materials thoroughly fermented and mixed by the large wheel compost turning machine can effectively extend the die’s lifespan and improve production efficiency.

The unique feature of this equipment is its ability to tailor raw materials to the characteristics of different granulation equipment. Whether it’s raw materials with specific particle sizes required by fertilizer compaction machines or physical property parameters needed by other granulation equipment, the large wheel compost turning machine can prepare them for subsequent processes through precise fermentation control. This pretreatment is becoming increasingly important throughout the entire production line.

These scenarios necessitate the use of a half-wet material crusher to meet the needs of the production line!

by organic fertilizer production line

In the field of bio-organic fertilizer production, the half-wet material crusher, as a specialized piece of bio-organic fertilizer equipment, is not required for all production lines. Its core application scenarios are concentrated in addressing the pain points of half-wet material processing.

First scenario: The raw materials mainly consist of high-moisture organic materials. If the core raw materials of the production line are poultry and livestock manure, kitchen waste, municipal sludge, etc., these materials usually have a moisture content of 30%-60%, are highly cohesive, and prone to clumping. The anti-sticking blades and special chamber design of the half-wet material crusher can precisely solve the problem of wet material processing and ensure a smooth crushing process.

Second scenario: The production line requires refined pre-treatment. Fermentation is crucial in bio-organic fertilizer production. When the production line aims for efficient fermentation and improved nutrient uniformity in the final product, a half-wet material crusher is needed to refine the half-wet raw materials into uniform particles, laying a solid foundation for the subsequent fermentation process.

Third scenario: Processing special half-wet waste residue raw materials. Some production lines use industrial waste residues such as traditional Chinese medicine residue, distiller’s grains, and sugar residue as raw materials. These waste residues are mostly in a semi-wet state and contain fibrous or viscous components. The shear + compression dual crushing mode of the half-wet material crusher can efficiently decompose these special materials.

Fourth scenario: Large-scale bio-organic fertilizer production lines have high requirements for process continuity. If semi-wet materials are not properly processed, it can easily cause blockage and downtime of subsequent equipment. In this case, configuring a half-wet material crusher can stably process wet materials, prevent clumping and blockage, and ensure efficient and continuous operation.

Scientifically designing a disc granulation production line: Key steps and core considerations

by organic fertilizer production line

Disc granulation production lines have become the mainstream choice for organic and compound fertilizer production due to their high granulation rate, convenient operation, and adaptability to various fertilizer types. Building an efficient and stable production line requires careful consideration of initial planning, equipment matching, and process integration.

Initial planning requires precise needs assessment. First, clearly define the production capacity target and determine the model and specifications of the disc granulator based on your production scale, avoiding overcapacity or undercapacity. Second, analyze the characteristics ofthe raw materials, predicting the granulation difficulty based on parameters such as moisture content, particle size, and viscosity, providing a basis for subsequent equipment debugging and process setting. Simultaneously, plan the site layout rationally, reserving space for equipment installation, material transportation, and future maintenance to ensure a smooth production process.

Matching core equipment is crucial. In addition to the core disc granulator, suitable pre-processing equipment (crushers, mixers) and post-processing equipment (dryers, screening machines) are necessary: raw materials are crushed to a uniform particle size, then mixed and conditioned using a fertilizer mixer machine to improve granulation efficiency; the granulated wet particles need to be dried to remove excess moisture, and then screened to select particles of the correct size. It is essential that the capacity of all equipment is matched to avoid any single stage becoming a production bottleneck.

Post-installation debugging and standardized operation are indispensable. After the production line is built, small-scale trial production is necessary to adjust parameters such as disc rotation speed, inclination angle, and material moisture content until the granulation rate and uniformity meet the standards; simultaneously, establishing standardized operating procedures and regularly maintaining the equipment will ensure the long-term stable operation of the production line.

How ring die pelleting machines work and their advantages in granulation?

by organic fertilizer production line

In the world of powder granulation, various granulation technologies have their strengths. Whether it’s a rotary drum granulator suitable for high output and good pelletizing, a compact flat die pelleting machine, or a fertilizer compaction machine specializing in high-hardness products, they all play a crucial role in their respective fields. Among them, the ring die pelleting machine, with its unique structure and wide applicability, has become an indispensable piece of equipment.

From pelleted feed for livestock and poultry to fuel for biomass power generation, and the preparation of organic fertilizers, many seemingly insignificant granular items may have its contribution behind the scenes. It doesn’t have a fancy appearance; at its core is a ring die filled with precise holes. This process is essentially a highly efficient physical molding. The change it brings is intuitive: loose powder disappears, replaced by regular, solid granules. This transformation brings enormous practical value.

It’s worth noting that technological evolution has never stopped. For example, the new type two in one organic fertilizer granulator, which emerged to meet market demand, integrates multiple functions to simplify the process. However, the fundamental principles of ring die granulation, due to its reliability and efficiency, remain the cornerstone of many equipment designs.

It can be said that this silent industrial artist does not change the essence of the material, but powerfully endows it with the most practical form.

NPK blending fertilizer production line: Equipment selection and uniformity improvement

by organic fertilizer production line

The core advantage of NPK blended fertilizers lies in their flexible nutrient ratio, and this advantage is achieved through the precise coordination of various blending and mixing equipment in the production line. Whether it’s a BB fertilizer mixer, an NPK blending machine, or a bulk blending fertilizer machine, the selection, suitability, and operating status of the equipment directly determine the nutrient uniformity and market competitiveness of the final product.

Equipment selection must match production needs. Small and medium-sized production lines are suitable for BB fertilizer mixers, which are easy to operate and have low energy consumption, meeting the needs of small-batch, multi-ratio blending, especially suitable for customizing special fertilizers for regional crops; large-scale production is more suitable for NPK blending machines, which have large mixing capacity and high mixing efficiency, and can ensure the full integration of nitrogen, phosphorus, potassium, and trace elements through a multi-stage mixing structure, adapting to a continuous production rhythm. Bulk blending fertilizer machines focus on the on-site blending needs of bulk materials, offering strong flexibility and effectively reducing packaging and transportation costs, suitable for direct supply to large planting bases.

Operational optimization is key to ensuring uniformity. Regardless of the equipment used, the feeding sequence and speed must be strictly controlled, following the principle of “fine materials first, then coarse materials; light materials first, then heavy materials,” to avoid material stratification; at the same time, the mixing speed and time should be adjusted according to the material characteristics to prevent over-mixing leading to material segregation, or insufficient mixing resulting in uneven nutrient distribution.

In summary, an NPK blending fertilizer production line needs to rationally select a BB fertilizer mixer or a bulk blending fertilizer machine based on production capacity and application scenarios, and optimize operating parameters to consistently produce high-quality blended fertilizers.
