Quality Granular Fertilizer Production

 Granular fertilizer is favored by customers. Now there are more and more granulator manufacturers using chemical fertilizer in the market. Some new fertilizer manufacturers do not know the equipment well in the fertilizer production line. It is inevitable that there is no need to operate such a group of equipment, which leads to the uneven processing of fertilizer granules and the production of fertilizer particles.

 SX heavy industry has uneven fertilizer granules for the convenience of customers' use and processing Production problems and solutions of granulator for chemical fertilizer.

Matters needing attention in chemical fertilizer production:

1. The granulation process of fertilizer granulator is the fourth process in the chemical fertilizer production line, and the impact process before the granulation process has obvious impact on the granulation process, because the fineness and complete crushing will directly affect the granulation molding.

2. Granulating fertilizer source of drum granulator is used for processing and production, and the requirements for particles are different, ranging from 3 mm in diameter, 4 mm in diameter to 1 cm in diameter. Therefore, the production and processing of particles with different diameters are different from the requirements of grinding fineness. Generally speaking, the smaller the particle diameter is, the higher the requirement for grinding fineness is, the thinner the crushing is, and the better the uniform particles are formed.

3. If not thoroughly crushed, there will be large particles and small particles of raw materials. The processing of grain materials is not uniform, and the fineness of granular materials is not up to standard, which will also affect the formation of particles. Therefore, the crushing effect of the production line in the process of fertilizer production is very large. If it is found that the fertilizer granulation equipment is handling uneven particles, it is OK To start the disease from the comminution stage.

Large number of fertilizer granulator, with the characteristics of wide and heavy granulator, welcome to investigate!

Disc Granulator Structural Design

Pan Granulation Rate

Disc granulator is a new type of inclined plate pelletizing equipment, the granulation rate is more than 95%. The granulator of disc granulator has three discharge ports, which is convenient for intermittent production and greatly improves the labor efficiency. The production capacity can reach 24t / h. The reducer and motor are driven by flexible belt to make the starting stable and reduce the impact force. The bottom of the pelletizing pan is reinforced with a number of radiating steel plates, which are durable and non deformable. The thickened base design eliminates the need for anchor bolts. The main gear of granulator is quenched by high frequency, and its service life is doubled.

Performance 

Disc granulator has the advantages of uniform granulation, stable operation, high sphericity, high roundness, intuitive operation and convenient maintenance.

How does it work?

The raw powder is evenly wetted by the atomized water in the material mixer to form a spherical core with very uniform particle size, and then sent to the spherical disc for spherical formation. The moisture content of the ball should be controlled at 12-14%. Most of the water should be added to the twin shaft mixer. Only a small amount of make-up water is added to the ball plate, and the amount of water added is controlled at about 0 to 3%.

Finished products by pan granulation

The dry powder is directly added to the spherical plate and sprayed with appropriate amount of water. The core of raw material enters into the ball disc and is affected by centrifugal force, friction force and gravity, and moves along the parabola. Due to the adhesiveness and plasticity of materials, the cores adhere to each other and grow gradually in the process of movement. When the tilt angle, the height of the disc edge, the rotation speed and the humidity of the disc remain unchanged, the balls with different particle sizes will roll down from the edge of the disc at different exit angles due to different gravity. In the continuous rolling process, the ball constantly discharges water from the ball surface. Due to the cohesiveness of the material and the natural volatility of the liquid film on the surface, the ball has a certain strength, and then the swash plate body rotates. Both sides of the disc are discharged out of the carton. Detailed info, go here.

Compost Turners Applications

In the modern industrial organic fertilizer production line, aerobic composting is a method that uses organic fertilizer production equipment to convert aerobic microorganisms into organic fertilizer, so that livestock manure and other organic substances are harmless under aerobic conditions. 

The main function of composting turning machine is to control temperature and volatile water, increase oxygen in composting process and meet aerobic fermentation conditions. Composting turning machine promotes efficient fermentation of livestock manure. According to the fermentation mode of organic matter composting process such as livestock manure, composting machine can be divided into two types: tank type and belt type.

Organic fertilizer production line ditch composting turning machine

The grooved composter is suitable for organic fertilizer production line with fermentation tank. The track is laid on the wall of the long fermentation tank. The tank type composting and turning machine can walk along the track of the fermentation tank to save energy. The turning machine can be operated automatically and conveniently. Ditch composting turning machine is widely used in organic fertilizer production and is the main self unloading equipment for livestock manure composting. The composting turning machine designed by us contains strong stirring teeth and rotates animal materials by mechanical rotation. It has strong production capacity per unit time and large processing output.

Cow Dung Compost

Organic fertilizer production line popular composting truck

The popular composting truck is a walking dump truck, suitable for stacking compost. Windmill composting machine is mainly used in large-scale farms and other large-scale fields to stack compost, without the need to build fermentation tanks. However, strip composting has the characteristics of low depth, slow heating and large space occupation, so the site environment is not good when the wind direction composting turning machine works. Windmill composting truck is mainly composed of driving device, dump device and transmission system. It is usually driven by an internal combustion engine and is a diesel engine.

Double Roller Granulator Installation Guides

 Guide for installation and commissioning of organic fertilizer double roller granulator

1. Installation:

After arriving at the plant, the drum extrusion organic fertilizer granulator will be installed with granulator as the main machine. According to the number of units and the organic fertilizer manufacturing process flow chart, the elevation and horizontal position are found. There are corner holes in the frame, which can be installed on the concrete (the solid vibration is not large, and a very solid concrete foundation is not required).

2. Debugging:

Our double roller granulator has been debugged before delivery, but it still needs to be adjusted after trial.

(1) Adjust the press roll clearance

In the production process, it is sometimes necessary to increase data output or data biting angle. In this case, the distance between the two compression shafts can be increased and the clearance between the drive shaft roller and the drive shaft can be increased.

The steps are as follows: stop the roller granulator, remove the frame above the two bearing blocks, adjust the adjusting plate between the two bearing blocks to the required thickness, prevent the roller collision between the two rollers, and maintain a minimum clearance of 0.3-1 mm. Go here for details.

(2) Ball and socket alignment adjustment

The ball and socket are formed by pits on the surface of the main roller, so there are problems of axial alignment and circumferential alignment.

Axial alignment has been adjusted during installation. Generally speaking, the possibility of adjustment is very small. When adjustment is required, tighten or loosen the seal rings on both sides of the passive bearing housing to push the displacement of the eccentric sleeve corresponding to the roller of the drive shaft.

Align the circumference. The steps of circumferential alignment are as follows: loosen the 6 connecting bolts of the drive gear and the adjusting sleeve, so that the adjusting sleeve and the driving gear are slightly separated. Since a spherical and socket adjustment is considered in the design and two adjusting bolts are provided, the deviation can be adjusted no matter the deviation is too large. As the ball sleeve of the double roller granulator is too small, the paperboard is placed between the two rollers during the adjustment process. After scrolling, you can see whether the adjustment has achieved the goal. After alignment, tighten the 8 connecting bolts.
