Working principle and granulation process of organic fertilizer drum granulator

fertilizer granulator Nov 18, 2023

The organic fertilizer granulation equipment drum granulator is a molding machine that can manufacture materials into specific shapes. The cylinder is lined with special rubber plates or acid resistant stainless steel plates, achieving automatic scar removal and tumor removal, eliminating traditional devices. A drum type granulator, in which steam, gas ammonia, or phosphoric acid or nitrogen solution, phosphorus ammonia slurry, and heavy calcium slurry are introduced to complete the chemical reaction and heating process of compound fertilizer granulation in the cylinder; Alternatively, in the cold granulation process of adding a small amount of water to the compound fertilizer, the materials that need to be granulated are rotated through the cylinder, causing rolling rotation when there is no material in the cylinder, and then agglomerated into balls at a certain humidity and temperature to complete the granulation process.

The working principle of the organic fertilizer drum granulator: The rotating components of the traditional horizontal centrifuge are separated into two parts: the inner and outer shaft systems that rotate synchronously. The outer shaft system is fixed axially, and the inner shaft system can move axially under the action of the synchronous rotating oil cylinder. The filter cloth is bag shaped, with one end fixed to the large end of the drum on the outer axis and the other end fixed to the small end of the push plate on the inner axis. During separation, under the action of centrifugal force, the filtrate passes through the filter cloth and drum, and the solid is intercepted by the filter cloth and forms a filter cake; When unloading, under the action of synchronous rotating oil cylinder, the inner shaft system is pushed out along the axial direction and drives the filter bag to flip, while completing the operation of filter cake unloading and filter cloth regeneration.

The granulation process of organic fertilizer granulation equipment is: the main motor drives the belt and pulley, which are transmitted to the driving shaft through a reducer. The split gear installed on the driving shaft engages with the large gear ring fixed on the body, working in opposite directions. The material is added from the feeding end and passes through the inside of the cylinder. Through the special structure inside the cylinder, it is made into particles and flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production can be achieved.

What aspects need to be considered when building a small organic fertilizer plant

fertilizer granulator Nov 18, 2023

Recently, the investment project to open an organic fertilizer processing plant has become a popular project, as organic fertilizer can be said to be a marketable product with policy subsidies and support. Many people want to open a small organic fertilizer processing plant, although it is a small organic fertilizer plant, its profitability is not small, and it is also a block in the current cycle. But having a cavity full of enthusiasm is not enough. Let’s take a look at what aspects need to be considered when building an organic fertilizer plant together?

1. Selection of raw materials for organic fertilizer production

There are many raw materials that can produce organic fertilizers, such as cow, sheep, pig and other livestock manure, urban sludge, animal and plant residues, straw, etc. Due to the difficulty in transportation of these raw materials, it is necessary to first determine them based on the principle of proximity. It is also possible to build factories around rich raw materials, which is the first step to consider and a top priority.

2. Production scale and annual output planning

Firstly, determine the expected production scale based on one’s own investment budget. If the investment scope is not limited, conduct in-depth investigation and research from the supply of surrounding raw materials, market demand, and other aspects to determine the expected production scale.

3. Selection of production site

Firstly, considering the cost of land use, choose regions with high cost-effectiveness. Then choose an area with complete water and electricity supply and convenient transportation. Next, choose the area with sparse surrounding residents and closest to the raw materials. You can look for it near the local farm.

4. Determine the process flow for organic fertilizer production

The determination of production process is very important, for example, there is a significant difference between powdered organic fertilizer and granular organic fertilizer. Not only do the finished products have different shapes, but also the production equipment required is different. It needs to be carefully studied and decided based on the surrounding market.

5. Plant construction planning

Visit and learn from large organic fertilizer manufacturers, or inquire with organic fertilizer equipment manufacturers, consider multiple factors, make reasonable plans for organic fertilizer factories, and finalize plans.

The granulation process and technical characteristics of a new type of organic fertilizer granulator

fertilizer granulator Nov 18, 2023

The new type of combined organic fertilizer granulator machine has the characteristics of simple organic fermentation fertilizer granulation with organic fertilizer texture, livestock manure, urine, composting fertilizer, green manure, sea fertilizer, cake fertilizer, peat, soil and miscellaneous fertilizer, three wastes, microorganism and so on. The particles are pellets.

The process of the new combined organic fertilizer granulator: according to the needs, several fertilizer raw materials are selected for metering and mixing, and the binder is used as the cement to form granules in the granulator. The granulation of dry powder mixture needs heating, adding water or steam to increase the liquid phase, and then agglomerate into particles in the granulator under rolling condition.
The qualified granulation rate of the machine is more than 80-90%. It can be used in many kinds of formulas. The compressive strength of organic fertilizer is higher than that of disc and drum, and the large ball rate is lower than 15%. The particle size uniformity can be adjusted according to the user’s requirements. The machine is more suitable for the direct granulation of organic fertilizer after fermentation, saving the drying process and greatly reducing the cost.

The granulation process and performance characteristics of disc granulator

fertilizer granulator Nov 18, 2023

The disc granulator can be used for various dry powder granulation and wet granulation of dry powder. Wet granulation has a good effect and should be prioritized. It is the main equipment for pelletizing powder materials, with advantages such as uniform pelletizing, easy control of water content in the pellets, high strength of the pellets, simple structure, convenient control, low power consumption, and smooth operation.

Principle of disc granulator: Various dry powder materials are added from the top of the equipment, degassed, spiral pre compressed, and transported to the curved grooves of two rollers. The two rollers rotate at equal speed and in reverse direction, biting the materials into the grooves and performing forced compression. The pressure the materials bear after passing through the compression zone gradually decreases, and their surface tension and gravity cause them to naturally come out. They enter the crusher and granulator for crushing and trimming, and then enter the vibrating screen for screening, Qualified products are sent to the finished product warehouse or directly packaged through a conveyor, and the powder screened materials are sent back to the raw material warehouse for secondary rolling through a feeding device. The size of the extrusion pressure can be adjusted by the hydraulic system according to the particle strength needs. By changing the groove form of the roller surface, materials such as flakes, strips, olives, and flat balls can be obtained.
