fertilizer granulator Oct 7, 2023

The ground composting and fermentation organic fertilizer production equipment, the walking tipper, is the main unit of a complete set of equipment dedicated to the production of bio organic fertilizers. The machine adopts a four-wheel walking design, which can move forward, reverse, and turn, and is operated and driven by one person. During driving, the entire vehicle rides on a pre stacked long strip of fertilizer base, and the fertilizer base raw materials are mixed, fluffy, and moved by a rotating blade shaft mounted under the frame. After passing by, the vehicle is tampered with into new strip piles. Operations can be carried out in open spaces or in workshop greenhouses. Advanced fermentation processes adopt microbial good fermentation, designed based on the principles of good fermentation, allowing fermentation bacteria to fully utilize their functions.

Ground composting and fermentation organic fertilizer production equipment, equipped with drum and knife shaped teeth, is mainly used for flat stacking and fermentation. It has dual functions of flipping and crushing. It can evenly mix materials and bacterial strains such as fecal base materials and sludge, and effectively break the plate lumps in the fermented materials. It is an essential specialized tool in fertilizer production operations.

The fermentation of walking type composting machine is an important step in the production of organic fertilizer using livestock and poultry manure, and flipping is an important measure to improve composting efficiency and the quality of composting products. Due to the fact that in the process of composting livestock and poultry manure to produce organic fertilizers, the flipping of fertilizers consumes a lot of manpower, material resources, and financial resources, and the research and production of slot type composting flippers can achieve a time-saving and labor-saving production effect.

The highly mechanized design of the walking stacker allows the stacker to achieve automatic feeding and discharging, achieving complete automation. One time flipping saves time and effort, takes only effort, and does not require much investment, which can save manpower and reduce production costs.

The raw materials for the production of organic fertilizers come from a wide range of sources, including plant residues, peat soil, humic acid, cow dung, chicken manure, sheep manure, duck manure, free manure, sludge, sugar mill filter mud, winery lees and so on. In response to different raw materials and the requirements for product quality and product output improvement, various organic fertilizer equipment manufacturers have developed various granulators, with different models and configurations, and fertilizer granulator machine price vary, such as double roller press granulator, stock transfer granulator , disc granulator machine, new organic fertilizer granulator, flat die granulator, ring die granulator, etc.

Double roller press granulator

The double roller press granulator can be used for the granulation of organic fertilizers such as livestock manure, kitchen waste, industrial waste, straw leaves, trough residues, oil and dry cakes, and npk fertilizer granulator for compound fertilizers such as nitrogen, phosphorus and potassium. Granulation of chemicals, feed, etc. The roller extrusion granulator belongs to dry granulation, no drying process is required, high granulation density, good fertilizer efficiency, full organic matter content, advanced technology, compact structure, novel and practical, and low energy consumption. Save the cost of buying dryer and cooler, no need to burn coal in the later stage, which saves a lot of money. If the organic fertilizer produced by machine-seeded farmers should use this granulation process with caution, it is recommended to choose compound fertilizer.

Disc granulator machine

Granulation raw materials include bio-organic fertilizer, pulverized coal, cement, clinker, fertilizer, etc. A disc granulator machine is a more traditional granulation process. Personally, I advocate this granulator, the granulation is smooth, it sells well, the price of the equipment is low, the only downside is the low density. The particle diameter has a large selection range, can be adjusted flexibly, and has a beautiful and uniform appearance. The granulation disc is reinforced with multiple radiant steel plates, which is durable and not easy to deform. The disc of the equipment adopts an overall arc structure, and the granulation rate is as high as 93%.

Application of Flat Mold Granulator in Organic Fertilizer Production Line

fertilizer granulator Oct 7, 2023

The granulating organic fertilizer equipment commonly used in the production of organic fertilizers includes disc granulator machine, npk fertilizer granulator, drum granulation, wet granulator, roller extrusion granulator, flat die granulator, ring granulator, etc. The fertilizer granulator machine price varies. Let’s take a look at the flat die granulator.

Flat die granulator is suitable for granulation of rough fermented organic fertilizer. Mainly suitable for coarse fiber granulation, such as: wood chips, rice husks, cotton stalks, cottonseed husks, weeds and other crop straws, household garbage, waste plastics and factory wastes, granulation of materials with low adhesion rate and difficult to form , briquetting, bar making, and also suitable for low-temperature granulation of biological bacterial fertilizer, organic fertilizer, compound fertilizer, etc.

The advantages of the flat die granulator are: wide adaptability of raw materials, especially for organic substances, wide requirements on raw material density and raw material moisture, and raw materials do not need to be dried. The diameter of the pressing roller is large, the template can be used in both positive and negative directions, the material is evenly distributed in the compression chamber, the granulation is stable, the particle forming rate is high, the appearance of the finished particles is uniform and not easy to break, the production capacity: 1.0 ~ 4.0 tons / hour; % or more, less material is returned; power: 22 to 90 kilowatts. No water is added in the whole granulation and forming process, which saves the cost of subsequent granule drying. The requirements for the fineness of raw materials are not high, and the granulated raw materials (after composting) generally do not need to be finely pulverized, and small stones can be directly crushed.

The disadvantages of the flat die granulator are: the flat die granulation machine consumes a lot of energy, and the extrusion strength is large. When iron and steel waste is mixed into the organic fertilizer raw material, it is very easy to damage the granulation template and sometimes block the granulation template hole. Additional equipment care and replacement of consumables are required. At the end of each shift, it is best to add blocking materials to granulate to prepare for the next shift of workers.

The price of a small organic fertilizer production line with an annual output of 10000 tons

fertilizer granulator Oct 7, 2023

Organic fertilizer also contains three elements of nitrogen, phosphorus and potassium 5%, and organic matter 45%, which can provide comprehensive nutrition for crops. The actual utilization rate of chemical fertilizers is only 30% to 45%, and some of the chemical fertilizers are fixed in the soil and cannot be directly absorbed and utilized by plants. When organic fertilizer is applied, due to beneficial biological activities, the soil structure is improved, the soil water and fertilizer retention capacity is increased, and the beneficial microorganisms can dissolve phosphorus and potassium, which can increase the effective utilization rate of chemical fertilizers to more than 50%.

Simple organic fertilizer equipment configuration includes pulverizer, mixer, granulator, screening machine and packaging machine. The  different configuration size fertilizer granulator machine price varies, and the whole set of equipment is only 50,000 to 60,000 yuan.

The complete set of equipment configuration includes fermentation equipment, pulverizer, mixer, disc granulator machine, dryer, cooler, screening machine, coating machine and packaging machine, as well as a conveyor for material transportation between the equipment. Such a complete set of equipment configuration requires 200,000 to 300,000, but the entire production line only needs five or six workers to complete the production operation and realize automated production.

If you invest in a small organic fertilizer production line with an annual output of 10,000 tons, it will cost about 220,000-250,000. This includes: the need to build a rain-proof steel structure greenhouse during the production process; labor wages; depreciation, electricity, and miscellaneous expenses. To open a small organic fertilizer factory, an organic fertilizer production line with an annual output of less than 10,000 tons is usually enough, and a high degree of automation requires 200,000 to 400,000 to 500,000 yuan. A more suitable individualized production line is generally a small organic fertilizer production line with an annual output of 5,000 tons of about 100,000 yuan, including organic fertilizer turning machines, animal manure pulverizers, conveyors and other equipment. For better ones, forklifts and horizontal mixers can be added, npk fertilizer granulator, screening machine, weighing packaging machine and other complete sets of equipment, need about 300,000 yuan.

What should I do if the fertilizer particles processed by the fertilizer granulator are not round?

fertilizer granulator Oct 7, 2023

The principle of fertilizer granulator granulation is the process of material layer by layer wrapping, which requires a core. With a core, particles have a certain strength matrix, and particles are less prone to deformation. If all of the particles are produced with new materials, no returns or very little returns, and there is no core, the liquid phase will increase when encountering high temperatures, making the particles appear particularly soft. In addition, the internal copying board of the equipment will copy the particles to the top and drop them vertically, causing the originally round particles to fall into a round and flat shape. To change this situation, first lower the temperature of the dryer to reduce the solubility of the material; The second is that there must be enough in the return volume Ф 1-2 mm small particles.

If the formula is not reasonable, excessive use of viscous fillers can also cause particles to be out of round. When using PVC lining inside the fertilizer granulator, each shift must shovel all the accumulated materials inside (tools such as shovels cannot damage the smooth surface), and adjust the tilt angle to the appropriate level. The smoothness and sphericity of the product are still good. The roundness of particles is a quality indicator that every factory attaches great importance to. In the production process, the more round the particles are made, the higher the output, so it is also higher. Therefore, most manufacturers consider the roundness of their own products as a key content of technical research and an important indicator of measuring the technical level of a complex factory.

The formation process of high concentration composite fertilizer particles is as follows: initially, small particles with a diameter of 1~2mm in the returned material are used as the core. Under the conditions of 60~650C temperature and appropriate liquid phase, under the rolling of the powder material and mechanical power, the particles are wrapped layer by layer to form soft particles with a diameter of 2~4mm. Then, the moisture of the material gradually evaporates in the dryer, and the soft particles gradually solidify, forming normal particles with a certain strength.

The liquid phase exceeds the standard, and the powder content is low during the granulation process of the fertilizer granulator. The particles lack a flat and filling powder material during rolling. Therefore, the moisture inside the granulator should be controlled to be dry, as long as it causes Ф 1-2mm particles are recommended and should not cause damage Ф 2-4mm qualified particles. Due to the excessive liquid phase, there is material bonding and large particles on the lifting plate and cylinder wall inside the dryer. Due to the lack of smooth conditions in the dryer, the particles will be irregular.

A small amount of finished products and excessively high drying temperature can also cause particle breakage and the formation of irregular particles.
